Objectives: The purpose of this study was to explore the moderating effect of stress coping styles on the relationships between loss experiences and depression of the men and women elderly. Method: The subjects of the study were 116 men and 156 women aged over 60 years. For the data analysis, frequency, Cronbach's ${\alpha}$. Pearson's correlation coefficients, and multiple regression were used. Results: The main results were as follows: First, elderly men reported higher role loss experience, relation loss experience, and problem-focused coping styles than elderly women. Also elderly women reported higher bereavement experience than elderly men. Second, there were main effects of health loss experience, economy loss experience, role loss experience, relation loss experience, problem-focused coping style, and emotion-focused coping style on depression of elderly men and women. Third, problem-focused coping styles moderated the relationships between physical health loss experience, economy loss experience, role loss experience and depression in the elderly men group. Last, social support-seeks coping styles moderated the relationships between economy loss experience and depression in the elderly women group. Conclusions: These results were discussed in terms of educational programs related stress coping strategies for the elderly.

The objective of this study is to find out the effect of yeast on hair loss treatment and the role of hair follicle stem cell activator, which is important in hair growth. The authors have recently produced a substance, which has no disgusting odor, does not precipitates and does not easily corrupt, to use instead of yeast acquired from raw rice wine(Makgeolli). The substance is named Yeast Constituent Extract(YCE). In this research, the Produced YCE was applied on the hair loss area of 10 Androgenic alopecia patients, twice every day for 6 months, in order to test the effect of hair loss treatment and the role of stem cell activator. As a result, all of the patients showed a significant growth of hair after 3 months of test, and showed much more growing, thickening and strengthening of hair after 6 months. As a result of measuring the number of hair strings in the same scalp region of the patients after 6 months, it is found that the density of hair has increased, indicating that the hair loss treatment was effective. Also the hair follicle stem cell was isolated from the patients and the contents of growth factors (IGF, VEGF, FGF, HGF) derived from hair follicle stem cell were measured with ELISA. As result, the amount is found to be about 10 times greater than before the test. The hair follicle stem cell contains many growth factors that affect growth of hair, so it takes a highly important role in hair loss treatment. The YCE that the authors have produced was found to be effective in increasing the contents of growth factors that are derived from hair follicle stem cell. Thus it can be inferred that the YCE plays a role as a stem cell activator that activates the hair follicle stem cells. In conclusion, the YCE is considered to be highly effective for hair loss treatment and to have a role as a stem cell activator.

본 연구의 목적은 (1) 자녀의 독립과 은퇴에 직면하는 중·노년기에 부모 및 직업역할의 비중축소를 통한 역할 재구조화와 심리적 안녕감 간의 관계를 알아보고, (2) 부모 및 직업역할 재구조화에 영향을 미치는 심리사회적 요인을 살펴보는 것이다. 역할 재구조화는 부모 및 직업역할에 대한 집착 정도로 측정하였으며, 일본의 기혼남녀 378명을 대상으로 우편조사를 실시하였다(회수율 48.3%). 그 결과, 부모 및 직업역할에 집착할수록 그 역할에 대한 상실불안감이 증대되어 심리적 안녕감이 저하되는 경로가 여성에게서 확인되었다. 역할집착의 개인차 요인에 대한 분석 결과, 남성의 경우 자율성이 높고 성역할태도가 전통적이며 사회적 지지망이 협소할수록 직업역할에 집착하였다. 여성의 경우 성역할태도가 전통적이고 사회적 지지망이 좁을수록 부모역할에 집착하였으며, 성역할태도가 비전통적일수록 직업역할에 집착하였다. 본 연구의 결과는 중·노년기의 역할 재구조화의 중요성 및 성별 사회화 과정에 따른 역할 재구조화의 성차와 관련지어 논의되었다.

Research has emphasized that relationship marketing programs enhance customer satisfaction and reduce switching intentions by building switching barriers. However, the psychological reactance theory demonstrates that building switching barriers can make customers fsel that the alternative not chosen is more attractive, because their freedom of choice has been deprived. It can be hypothesized that a relationship marketing program, which is intended to offer various benefits to customers, may not result in positive customer attitude and behavior. This paper examines the effects of relationship marketing programs on customers' perceptions of switching cost and loss of freedom. The effects of those perceptions on customer satisfaction and switching intentions were identified. In addition, the moderating role of personal reactance was examined. The results of this study suggest that (1) perceived switching cost has significant influence on boosting perceived loss of freedom; (2) perceived loss of freedom has no significant effects on customer satisfaction; (3) perceived loss of freedom enhances customers' switching intentions. Furthermore, psychological reactance has a significant influence on customers' switching intentions. This study concludes that the role of relationship marketing programs should be reconsidered, especially in terms of customers' switching intentions. Customer satisfaction is not the key factor of predicting customers' future behavior.

Genetic hearing loss crosses almost all the categories of hearing loss which includes the following: conductive, sensory, and neural; syndromic and nonsyndromic; congenital, progressive, and adult onset; high-frequency, low-frequency, or mixed frequency; mild or profound; and recessive, dominant, or sex-linked. Genes play a role in almost half of all cases of hearing loss but effective treatment options are very limited. Genetic hearing loss is considered to be extremely genetically heterogeneous. The advancements in genomics have been instrumental to the identification of more than 6,000 causative variants in more than 150 genes causing hearing loss. Identification of genes for hearing impairment provides an increased insight into the normal development and function of cells in the auditory system. These defective genes will ultimately be important therapeutic targets. However, the auditory system is extremely complex which requires tremendous advances in gene therapy including gene vectors, routes of administration, and therapeutic approaches. This review summarizes and discusses recent advances in elucidating the genomics of genetic hearing loss and technologies aimed at developing a gene therapy that may become a treatment option for in the near future.

Hair loss causes psychological stress due to its effect on appearance. Therefore, the global market for hair loss treatment products is rapidly growing. The present study demonstrated that ginseng berry-derived and sequence-modified peptides promoted the proliferation rate of dermal papilla (DP) cells and keratinocytes, in addition to having antioxidant properties. Moreover, the potential role of these ginseng berry peptides as TGF-β2 antagonists was confirmed through in silico computer docking. In addition to promoting the growth of ,the ginseng berry-derived peptides also promoted the proliferation of keratinocytes experimental Particularly, an unmodified ginseng berry-derived peptide (GB-1) and two peptides with sequence modifications (GB-2 and GB-3) decreased ROS generation and exhibited a protective effect on damaged HaCaT keratinocytes. Computer-aided peptide discovery was conducted to identify the potential interactions of important proteins with transforming growth factor-beta 2 (TGF-β2), a key protein that plays a crucial role in the human hair growth cycle. Our results demonstrated that MAGH, an amino acid sequence present in herbal supplements and plant-based natural compounds, can inhibit TGF-β2.

It has been known that ring current particles can be lost through dayside MP(magnetopause). However, details of the loss mechanism of this process has not received much attention. In this study, we show that the solar wind dynamic pressure P$\sub$D/ can play a significant role in the dayside loss. In order to show that, we have first conducted superposed epoch analysis using 95 geomagnetic storm events selected from the period 1997 to 2002. (omitted)

Queueing models are good models for fragments of communication systems and networks, so their investigation is interesting for theory and applications. Theses queues may play an important role for the validation of different decomposition algorithms designed for investigating more general queueing networks. So, in this paper we illustrate that the batch size distribution affects the loss probability, which is the main performance measure of a finite buffer queues.
