A Local Currency in a Dollarized Economy  [PDF]
Sokchea Lim
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.35086
Abstract: The paper uses a dual-currency search theoretic approach to demonstrate that it is possible to induce the acceptance of a local currency in a dollarized economy. In the model, we assume that a foreign currency is in full circulation and the government policy tool is the convertibility of the local currency to the foreign currency. We show that the economy can achieve equilibria where two monies are in circulation if the government can raise a sufficiently high probability of exchange between the two currencies.
Taijin-Kyofu-Sho: A subtype of social anxiety  [PDF]
Leslie Lim
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.34042

Taijin-Kyofu-Sho (TKS) has long been considered as a Japanese culture-bound form of social anxiety disorder, although subsequent case-reports from countries outside Japan have dispelled this notion. There are subtle yet distinct differences between TKS and DSM-defined social anxiety disorder (SAD). For instance, the TKS subject fears causing offence to others, whereas the SAD subject is more fearful of causing embarrassment to him/herself. Four sub-categories of TKS have been recognised of which the Jikoshu-kyofu variety resembles the olfactory reference syndrome (ORS) known to Western psychiatrists. There are two TKS subtypes, general (or simple) and offensive (delusional). The general subtype resembles social anxiety disorder, whereas the offensive subtype is characterised by delusions. True community-wide prevalence is unknown, although clinic studies estimate between 7.8% to 45.5% patients have a diagnosis of TKS, with a slight male preponderance. Cultural and societal norms engendering guilt, shame, and embarrassment are likely etiological factors. Treatment may consist of antidepressant and/or antipsychotic medications, while some patients may also benefit from cognitive behavior therapy.

An Analysis of the Jonsei and Purchase Prices in the Korean Housing Market  [PDF]
Gieyoung Lim
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.61007
Abstract: The primary purpose of this paper is to construct and estimate an econometric model for the Jonsei-to-Purchase price ratio (JPR), and to draw implications for the development in the Korean housing market. In particular, we are interested in: a) identifying regimes across which the ratio shows markedly different dynamic behavior; and b) drawing implications from the model for the recent increases in the ratio. Estimation of the model for the period 1987:Q1-2011:Q3 confirms the presence of two different regimes: one with the zero trend in the JPR, and the other with positive trend. Furthermore, it is found that cyclical variations play nontrivial role only in the first regime, while the movements of the JPR in the other regime are mostly governed by the trend component. We also find that the cyclical deviations of the ratio from its trend are corrected, if any, by the changes in the future purchase price.
The Growing Evidence for Photobiomodulation as a Promising Treatment for Alzheimer’s Disease  [PDF]
Lew Lim
Journal of Biosciences and Medicines (JBM) , 2018, DOI: 10.4236/jbm.2018.612010
Despite the current belief that there is no effective treatment for Alzheimer’s Disease (AD), one emerging modality may change this belief: Photobiomodulation (PBM). It has credible mechanisms and growing evidence to support its case. Transcranial PBM for AD is a single intervention with multiple pathway mechanisms stemming from delivering low energy near infrared (NIR) light to the mitochondria in brain cells. The mechanisms involve the activation of gene transcription that lead to neuronal recovery, removal of toxic plaques, normalizing network oscillations that can lead to improved cognition and functionality. When PBM is delivered at 810 nm wavelength and pulsed at 40 Hz, early evidence suggests that very significant outcomes are possible. Literature related to PBM and AD has covered in vitro cellular, animal and human case reports, with promising results. They warrant robust randomized trials which are either ongoing or ready to start. The evidence in human studies is manifested in assessment scales such ADAS-cog, MMSE, and ADAS-ADL, and are supported by fMRI imaging and EEG.
Social Connectedness Predicts Lower Loneliness and Depressive Symptoms over Time in Adolescents  [PDF]
Paul E. Jose, Bee Teng Lim Lim
Open Journal of Depression (OJD) , 2014, DOI: 10.4236/ojd.2014.34019

Although research has shown that loneliness in adolescents leads to higher rates of depressive symptoms, the presumed protective factor of social connectedness has not been studied in conjunction with these two constructs. The aim of the present study was to determine if social connectedness would predict lower loneliness and depressive symptoms over time in a large sample of adolescents. A large sample of adolescents (N = 1774; 9-16 years at Time 1) were surveyed three times, separated by one year each, with self-report measures of social connectedness, loneliness, and depressive symptoms obtained. As expected, social connectedness was negatively associated with loneliness and depressive symptoms concurrently and longitudinally. Contrary to prediction, social connectedness did not function as a buffer between loneliness and depressive symptoms over time. However, consistent with prediction, a significant longitudinal mediation pattern was obtained over the three years: the effect of social connectedness on depressive symptoms was mediated by loneliness. Social connectedness at T1 predicted a reduction in loneliness at T2, which in turn predicted a reduction in depressive symptoms at T3. Moderation analyses of this mediation pattern suggested that this obtained mediation result was obtained for males, but not females, and obtained for older adolescents, but not for younger adolescents. The results are congruent with the view that social connectedness exerts an effective protective influence on adolescents against loneliness and depressive symptoms.

Legacy of the Asian Currency Crisis: The Case of Korea  [PDF]
Jangryoul Kim, Gieyoung Lim
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.38118
Abstract: This paper reexamines the long run effects of the 1997 Asian crisis on the Korean economy. Using unobserved components models subject to Markov regime-switching, we address two questions:1) whether the output losses of Koreaduring 1997-1998 were permanent or transitory;2) when the trend growth rate decreased. Estimation results suggest that the trend growth rate of the Korean economy has already declined around 1992-1993 prior to the 1997 crisis, and given the transition of the Korean economy into the low-growth regime in the early 90s, the effects of the crisis are mainly transitory.
Ballistic Behavior of Heracron®-Based Composites: Effect of the Number Multifilaments on High-Speed Projectiles  [PDF]
Jung Seop Lim
Modeling and Numerical Simulation of Material Science (MNSMS) , 2013, DOI: 10.4236/mnsms.2013.33011
Abstract: In this study, two Heracron? woven fabrics, HT840-1 and HT840-2, were fabricated with different multifilament fibers, and their resistance to ballistic impact was investigated. For the same weight and number of plies, the HT840-2 fabric showed improved ballistic properties, compared with HT840-1; this result is contrary to the fiber and fabric properties. With the exception of the yarn’s physical properties, this behavior can be explained in terms of the number of multifilaments, which strongly influenced the ballistic mechanism, i.e., a greater number of multifilament fibers facilitates energy dissipation from a high-speed ballistic projectile. In summary, establishing this optimal number of multifilaments is the key to optimizing the ballistic properties of any given fabric.
A Case Study on Peer-Teaching  [PDF]
Leng Leng Lim
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28006

This paper reports on the feedback of a case study on peer-teaching activity in a third year university mathematics course. The objective of the peer-teaching activity was to motivate learning and raise student commitment. From the questionnaires conducted, students welcomed the peer- teaching activity and their learning motivation was also improved.

Cognitive Behavior Therapy of Urinary Incontinence Phobia: A Case Report  [PDF]
Tina Tan, Leslie Lim
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.51009
Abstract: A significant association exists between lower urinary tract symptoms and anxiety. Despite the efficacy of cognitive behavior therapies in treating a variety of phobic disorders, there are few published reports about the use of such treatments for urinary problems. We report a case of the phobia of urinary incontinence treated with cognitive behavioral techniques, which involved cognitive restructuring, distraction, relaxation training, and exposure to feared situations.
Issues to Consider in Designing Immunotherapy Clinical Trials for Glioblastoma Management  [PDF]
Adela Wu, Michael Lim
Journal of Cancer Therapy (JCT) , 2016, DOI: 10.4236/jct.2016.78060
Abstract: Glioblastoma (GBM) is the most common primary brain malignancy in adults and has a poor prognosis despite standard of care treatment. The mainstay of GBM treatment has relied on maximum surgical resection and chemotherapy and radiation. Cancer immunotherapy has made great strides since the advent of anti-PD-1, anti-CTLA-4, and other immune checkpoint inhibitors. With the advancement of novel therapeutics, more clinical trials for patients have opened as well. An important future direction of clinical trials is the ability to identify appropriate patients to optimize treatment response and minimize toxicities. This review describes considerations in designing future GBM clinical trials in not only immunotherapy but also with other promising treatments. We will discuss factors, such as pseudoprogression, genetic and circulating biomarkers, and the commensal microbiome of patients in the setting of clinical trial design.
