Purpose: The cane is one of the most popular assistive devices for stroke patients. Clinical complaints of sensorimotor functions on the ipsilateral upper limb were appealed in stroke patients who had used a cane for a long period. Therefore, we investigated whether cane usage for a long-term period affected sensoriomotor dysfunctions on the non-affected upper limb, in terms of pain presence, shoulder joint sense, a nine-hole pegboard test, and a tracking task. Methods: We recruited 12 stroke patients, who were divided into the cane-using (CU) group or the non-cane using (NCU) group, according to cane usage experience. We evaluated joint position sense for the integrity of proprioceptive reposition sense in the shoulder joint, used a nine-hole pegboard test for upper limb dexterity evaluation, and a tracking task for visuomotor coordination. Results: Four patients in the CU group had complained of shoulder pain none did in the NCU group. In addition, the CU group showed more reposition errors on the shoulder joint than the NCU group did. In addition, the CU group had more difficulty in proprioceptive sense perception and in performance of the nine-hole pegboard teat and tracking task, compared with the NCU group. Conclusion: Our findings suggest that cane usage for a long period in stroke patients could give rise to trigger joint pain and decrease proprioceptive sense. In addition, complex motor performance in the ipsilateral upper limb could deteriorate. In stroke patients who had used acane for long period, careful observation and proper intervention will be necessary.

As senile diseases increase with the aged increasing rapidly in an aging society, implementation of the aged long-term care insurance have an effect on the aged care and treatment. Though a decrease in prevalence rate can reduce social costs, the significance of that is overlooked. Especially, a program for a slight Alzheimer's disease and senile demetia in the spot of care facilities and welfare organs is nothing or a few programs which use only fragmentary techniques. So, In this paper, we propose a five-senses stimulation program for preventing senile dementia disease. It includes twenty processes stimulating five senses through proper harmony of senile dementia disease prevention techniques - hand exercises(sense of touch), remembrance therapy(sense of sight), cure recreation(sense of taste), music therapy(sense of hearing), gardening remedy(sense of smell).

The challenges to achieve three dimensional facial proportionality and occusal stability in many patients with complex dentofacial deformity have been met by the development and use of the maxilla, mandible, and chin surgery techniques in combination with efficient orthodontic treatment. There is a clinical, biological, and biomechanical foundation for simultaneous surgical repositioning of the maxilla, mandible, and chin in a significant proportion of adult and adolescent patients. A combination of the surgical and orthodontic approach may provide increased treatment efficiencies and optimal esthetic results. Art and science to determine the treatment objectives, specifically, the desired soft tissue changes are firstly established by using the clinician's "esthetic sense" of the facial beauty and proportion aided to a few cephalometric guidelines. In this sense, the dependence on the clinician's "esthetic eye" by Dr. Bell is more important in analyzing the facial proportion than the satisfaction of rigid cephalometric norms. The purpose of this article was to elucidate the indication for simultaneous surgical repositioning of the maxilla, mandible, and chin, and to describe the clinical cephalometric analysis for orthognathic surgery. Representative 6 case reports were presented and discussed to illustrate the esthetic, orthodontic, and surgical treatment objectives with long-term follow-up.

The study was applied to context window sizes and weighting method to obtain the best performance of word sense disambiguation using support vector machine. The context window sizes were used to a 3-word, sentence, 50-bytes, and document window around the targeted word. The weighting methods were used to Binary, Term Frequency(TF), TF ${\times}$ Inverse Document Frequency(IDF), and Log TF ${\times}$ IDF. As a result, the performance of 50-bytes in the context window size was best. The Binary weighting method showed the best performance.

In a conventional sense, dried-spermatozoa are all dead and motionless due to the lost of their natural ability to penetrate oocytes both in vivo and in vitro. However, their nuclei are completely able to contribute to normal embryonic development even after long-term preservation in a dried state when the dried-spermatozoa are microinjected into the oocytes. In this sense, dried spermatozoa must still be alive. Thus, defining spermatozoa as alive or dead seems rather arbitrary. Several drying method of sperm including freeze-drying, evaporative/convective-drying and heat-drying were represented in this review. Although the drying protocol reported here will need further improvement, the results suggest that it may be possible to store the male genetic resources.

In case of international long-term transactions, there are various risks of economic change of circumstances including skyrocketing price increase and shortage of raw material, as well as force majeure in a general sense. Nevertheless, pretty many of international long-term commercial contracts do not include the provisions of renegotiation and adaptation of the contract. In this case, possibility of renegotiation and adaptation depends mainly on the applicable law. Namely, it may be possible or not, according to choice of law. The reason is that national laws have nuances each other, and most of national courts are traditionally reluctant to accept hardship. and also, provisions of international uniform law (CISG) has ambiguity and inflexibility in relation to the problems of change of circumstances. Accordingly, this paper analyzes comparatively the doctrines and provisions related to renegotiation and adaptation of contracts of the most representative countries such as England, U.S.A., France, Germany as well as provisions CISG and soft law such as PICC. By doing so, the author makes clear which laws of instruments is more flexible or acceptable in allowing renegotiation and adaptation of long-term commercial contracts, and emphasizes on the importance of inclusion of express terms by using other alternative supplementing clauses, as a best solution for settling the problems of legal uncertainty of contract in relation to renegotiation and adaptation.

A dual substructuring method with a penalty term was introduced in the previous works by the authors, which is a variant of the FETI-DP method. The proposed method imposes the continuity not only by using Lagrange multipliers but also by adding a penalty term which consists of a positive penalty parameter ${\eta}$ and a measure of the jump across the interface. Due to the penalty term, the proposed iterative method has a better convergence property than the standard FETI-DP method in the sense that the condition number of the resulting dual problem is bounded by a constant independent of the subdomain size and the mesh size. In this paper, a further study for a dual iterative substructuring method with a penalty term is discussed in terms of its convergence analysis. We provide an improved estimate of the condition number which shows the relationship between the condition number and ${\eta}$ as well as a close spectral connection of the proposed method with the FETI-DP method. As a result, a choice of a moderately small penalty parameter is guaranteed.

Modernization drastically changed the cosmetic culture of Korea and Japan. A classic case that shows this is the appearance of the term 'Hyangjang (香粧)'. This paper investigated the background to the formation of the term Hyangjang (香粧), and reviewed the aspects of cosmetic culture that changed with the emergence of Hyangjangpum (香粧品), or cosmetics containing perfume. The investigation revealed that the term Hyangjang (香粧) appeared for the first time in Hirano (1899), a literature published in the Meiji period in Japan, and that the new term Hyangjang (香粧) had been formed against the background of advanced Western synthetic perfume and played an important role in contemporary techniques for the manufacture of cosmetics. The term Hyangjang (香粧) and cosmetics containing perfume, or Hyangjangpum (香粧品) were then introduced from Japan to Korea. In Korea, the term 'Hyangjang (香粧)' appeared for the first time in an advertising copy written by Hyeon Hui-un, a pioneer of the Korean modern theater movement during the period of Japanese colonial rule. At that time, cosmetic companies in Korea and Japan were releasing cosmetic products that contained perfume that stimulated a women's desire to purchase them by emphasizing 'fragrance' in their advertising. Existing public tendencies to regard a fragrant smell from a made-up face as vulgar were changing and the public perception of fragrance were also changing. The appearance of Hyangjangpum (香粧品) indicates that the existing cosmetic culture revolving around visual sense changed into a complex cosmetic culture involving olfaction. This change in culture is significant in that it heralded the direction of future development towards cosmetic culture that uses increase combinations of different senses including touch, taste, and hearing.

This paper derives the algorithm to estimate the operating cost, its marginal cost, and the reliability indices for the long term planning of power system. Treating the load duration curve and the system in the stochastic sense takes the place of the inverted load duration curve, effective load duration curve, and the numerical integration in the conventional methods. The time and accuracy of computation are substantially improved due to the fact that all expressions are represented by simple analytic form instead of the existing recursive form.
