In old age, measures to cope with the natural phenomenon of aging and various diseases of the elderly due to the deterioration of physical function are also a challenge for this society. While interest in systematic health is increasing, it is true that awareness and interest in oral-related diseases is relatively lacking. This study aims to present basic data necessary to improve the quality of life for senior citizens aged 65 or older by improving the oral dryness caused by systemic health. By research method, improve oral dryness caused by whole-body health with the elderly over 65 and promote their oral health, inducing the increase of the salivary flow rate through oral health care education, oral exercise, and salivary gland massage. First, on the DMSQ according to the general characteristics of the elderly, the recognition of the whole body and oral health status, independent sample t-test and One-way ANOVA were conducted. Second, on changes in the salivary flow rate and saliva pH according to the general characteristics of the elderly, recognition of oral and whole-body health status, and whole-body health, paired samples t-test was conducted. Studies have shown that salivary gland flow increased significantly after oral exercise and salivary gland massage, the salivary flow rate significantly increased. In all variables of the recognition of the oral health status, the salivary flow rate increased after oral exercise and salivary gland massage, and in the whole-body health, regardless of hypertension, diabetes, cardiovascular disorders, and osteoporosis, the salivary flow rate increased after oral exercise and salivary gland massage, and the salivary flow rate increased after oral exercise and salivary gland massage if the subjects responded that they did not have thyroid abnormality, anemia, abnormalities of breathing, hypotension, gastrointestinal disturbance, or kidney diseases. As a comprehensive analysis of this study, many felt oral dryness when they had a problem with the whole-body health, and many felt oral dryness when they had a problem with oral health cognition. After applying oral exercise and salivary gland massage as intervention methods in the oral health care for the elderly, the salivary flow rate significantly increased, and it is judged that the methods were very effective for controlling oral dryness. Furthermore, it is judged that the factors affecting oral health, whole-body health, and oral dryness would be identified, which would be helpful for the promotion of whole-body health and oral health. It is judged that continuous research would be needed so that measures for the application of the oral care program and system for the elderly would be prepared in the future.

Regulator of calcineurin 1 (RCAN1) binds to calcineurin through the PxIxIT motif, which is evolutionarily conserved. SP repeat phosphorylation in RCAN1 is required for its complete function. The specific interaction between RCAN1 and calcineurin is critical for calcium/calmodulin-dependent regulation of calcineurin serine/threonine phosphatase activity. In this study, we investigated two available deletion rcan-1 mutants in Caenorhabditis elegans, which proceed differently for transcription and translation. We found that rcan-1 may be required for calcineurin activity and possess calcineurin-independent function in body growth and egg-laying behavior. In the genetic background of enhanced calcineurin activity, the rcan-1 mutant expressing a truncated RCAN-1 which retains the calcineurin-binding PxIxIT motif but misses SP repeats stimulated growth, while rcan-1 lack mutant resulted in hyperactive egg-laying suppression. These data suggest rcan-1 has unknown functions independent of calcineurin, and may be a stimulatory calcineurin regulator under certain circumstances.

In women's clothing the shoulders are distorted and exaggerated. Consequently, the wearers' bodies are transformed and interpreted according to modern standards. We therefore refer to this aspect of women's clothing as the power shoulder. This study aims to analyze the differences in sensibility images on variations in the shoulder shape of power shoulder jackets. Nine samples were examined that involved combinations of three variations of the shoulder height and three variations of the shoulder width. The data was evaluated by 123 fashion design majors. Four factors were selected: attractiveness, personality, activity, and self-respect. Among these factors, attractiveness is the most important. The study results indicated that changes in shoulder height acted as a major effect that had an independent influence on all four factors. In contrast, changes in shoulder width acted as a major effect that had an independent influence on attractiveness, personality, and activity but not on self-respect. It also had an influence on the interaction effect of attractiveness, personality, activity, and self-respect. We anticipate that this study will help individual customers select clothing that is suitable for their preference and body shape because it is now possible for them to estimate images of power shoulder jackets.

Angiogenesis, the formation of blood vessels, is essential for preparing a closed circulatory system in the body, and for supplying oxygen and nutrition to tissues. Major diseases such as cancer, rheumatoid arthritis, and atherosclerosis include pathological angiogenesis in their malignant processes, suggesting anti-angiogenic therapy to be a new strategy for suppression of diseases. However, until the 1970s, the molecular basis of angiogenesis was largely unknown. In recent decades, extensive studies have revealed a variety of angiogenic factors and their receptors, including vascular endothelial growth factor (VEGF)-VEGFRs, Angiopoietin-Tie, Ephrin-EphRs and Delta-Notch to be the major regulators of angiogenesis in vertebrates. VEGF and its receptors play a central role in physiological as well as pathological angiogenesis, and functional inhibitors of VEGF and VEGFRs such as anti-VEGF neutralizing antibody and small molecules that block the tyrosine kinase activity of VEGFRs have recently been approved for use to treat patients with colorectal, lung, renal and liver cancers. These drugs have opened a novel field of cancer therapy, i.e. anti-angiogenesis therapy. However, as yet they cannot completely cure patients, and cancer cells could become resistant to these drugs. Thus, it is important to understand further the molecular mechanisms underlying not only VEGF-VEGFR signaling but also the VEGF-independent regulation of angiogenesis, and to learn how to improve anti-angiogenesis therapy.

Seoul Fashion Week aims to be the world’s fifth Fashion Week from the year after 2000. This has involved significant labour and investment, not all of which has been successful. This study analyses the strengths and weaknesses of SFW based on the London Fashion Week as a successful model. By identifying its obvious and less obvious characteristics, this analysis aims to diagnose SFW’s current status in order to upgrade the event at an international level. Key factors are organisational body, designers, visitors, sponsors, schedule, venue, main events and supportive events. The following points have emerged from the research: the success of Seoul Fashion Week was based on the combination of separate collections, an appropriate fashion show venue, and the active role of new designers. The problems were: lack of an independent organisation, non-professional staff, lack of diverse visitors, exclusive governmental funding, late timing, excessive distance from the main European and American fashion markets, lack of sustainability of the main events, a limited variety of supportive events, the absence of online promotion and, last but not least, no distinctive features. The study concludes that Seoul Fashion Week has great potential with its fast growth and young designers. This should be complemented with an independent organisation and effective administration and strategy.

Human postural responses appeared to have stereotyped modality, such as ankle mode, knee mode and hip mode in response to various perturbations. We examined whether human postural control gain of full-state feedback could be decoupled along with the eigenvector. To verify the model, postural responses subjected to fast backward perturbation were used. Upright posture was modeled as 3-segment inverted pendulum incorporated with feedback control, and joint torques were calculated using inverse dynamics. Postural modalities such as ankle, knee and hip mode were obtained from eigenvectors of biomechanical model. As oppose to the full-state feedback control, independent eigenvector control assumes that modal control input is determined by the linear combination of corresponding modality. We used optimization method to obtain and compare the feedback gains for both independent eigenvector control and full-state feedback control. As a result, we found that simulation result of eigenvector feedback was not competitive in comparison with that of full-state feedback control. This implies that the CNS would make use of full-state body information to generate compensative joint torques.

이방성 암석에서 결정되어야 할 탄성상수의 수는 전부 9개이므로 실험적으로 얻기 매우 어렵다. 대부분의 암반체는 등방성 또는 펑면이방성으로 해석할 수 있어 독립적 탄성상수의 수는 감소하며, 평면이방성체에서는 5개이다. 실험실 시험을 통하여 하나의 평면이방성체 시험편으로 얻을 수 있는 응력-변형률 관계식은 4개 뿐이므로 5개의 독립적 탄성상수를 결정하는 것은 이론적으로 불가능하다. Lekhnitskii는 많은 실험을 통하여 제 5의 관계식을 설정하여 이를 해결하였지만, 이 식은 이론적으로나 실제값과 비교하면 오차를 갖고 있다. 본 연구는 이방성체에서 응력-변형률의 관계와 탄성상수의 독립성에 대하여 설명하고 있으며, 한개의 평면이방성 시험편에서 5개의 독립적 탄성상수를 결정하는 실험실 시험법을 제시하고 있다.
