With e-commerce becoming international, understanding the effects of national culture in consumer acceptance of e-commerce is required. This study examines consumer e-commerce acceptance in Korea and China. The research model consisting of perceived usefulness, perceived ease of use, trust and perceived risk was proposed, and the hypotheses based on Hofstede's cultural dimensions of power distance, individualism/collectivism, masculinity/femininity, uncertainty avoidance and long-term orientation, were established. The results show that perceived usefulness contributes less to consumer acceptance of e-commerce in China than it does in Korea. In addition, perceived ease of use contributes more to consumer acceptance of e-commerce in China. Trust contributes significantly to consumer acceptance of e-commerce in both countries, but perceived risk didn't influence consumer acceptance of e-commerce in either country. The contribution of this study is to provide strategic insights for successfully managing cross-cultural e-commerce.

This study aims to point out the basic strategy of agrotechnical and -political approaches toward successful settling for the environmental agriculture system in Korea. Although environmental agriculture & forestry strategy toward the 21st century and it's action program were released in 1996, some scientist from environmental agriculture and organic agriculture still argue on the errors of it's strategy and action program in terms of environmental sound functions. Especially it's strategy and action program of government did not focus the reduction of fertilizer and pesticide as the matters of weight and importance to reduction of fertilizer and pesticide as the matters of weight and importance to realize an environmental sound agriculture system. And korean organic agriculture gets a point in dispute, because 1) they do not practice of Basic Standard of IFOAM and FAO/WHO Codex draft, and 2) organic farming is defined quite differently from internationally recognized core aspects of organic agriculture. Organic farming, in Korea, is taken to mean the replacement of chemical fertilizer by organic manure and avoidance of agricultural chemicals. In the paper it is discussed the necessity, purpose, effect and consequence of basic standard for korean organic agriculture. The reformation of the certification system and t he direct payment system in environmental agriculture & forestry strategy toward the 21st century and it's action program by government, and on the need of the teaching program and curriculum in high education institution, the breeding program of resistant cultivars, the soil testing for optimum fertilization strategy, the nutrient management program, the declaration for 2020 environemntal agriculture are also discussed.

The remedies available to a seller that has suffered a breach of contract by the buyer are addressed in Section III of Chapter III of Part III. The first provision in the section, 61, catalogues those remedies and authorizes an aggrieved seller to resort to them. The remaining provisions of the section address particular remedies or prerequisites to remedies. The subject matter of the current section remedies for breach of contract by the buyer obviously parallels that of Section III of Chapter II of Part III remedies for breach of contract by the seller. Many individual provisions within these sections form matched pairs. Thus 61, which catalogs the seller's remedies, which catalogs the buyer's remedies. Other provisions in the current section that have analogues in the section on buyer's remedies include 62, seller's right to require buyer's performance 63, seller's right to fix an additional period for buyer to perform and 64, seller right to avoid the contract. As was the case with the provisions on buyers' remedies, the articles governing sellers' remedies operate in conjunction with a variety of provisions outside the current section. Thus the seller's right to require performance by the buyer is subject to the rule in 28 relieving a court from the obligation to order specific performance in circumstances in which it would not do so under its own law. The authorization in 61 for a seller to claim damages for a buyer's breach operates in connection with 74-76, which specify how damages are to be measured. 49, stating when an aggrieved seller can avoid the contract, is part of a network of provisions that address avoidance, including the definition of fundamental breach, the requirement of notice of avoidance, provisions governing avoidance in certain special circumstances, measures of damages available only if the contract has been avoided and the provisions of Section V of Part III, Chapter V on effects of avoidance.

Objectives: University students's oral health care practice and oral health status are very important. Because its affect their systemic disease, so as to have confidence, and to be eager to study. However if they feel dental fear, they avoid dental treatment. It is miss opportunities of early treatment and prevention treatment and have little effect on dental treatment. The aim of this study was to investigate the factors influencing dental fear of university students to reduce their dental fear. Methods: A total of 366 self-administered questionnaires were collected from university student in Cheon-an. To investigate the factors influencing dental fear of university students, t-test, one-way ANOVA, correlation analysis, linear regression analysis were carried out by using SPSS ver. 18.0 Results: University students feel the most fear of specific dental stimuli. Especially, 'Feeling the needle injected'. University Students felt dental fear in order of 'fear of specific dental stimuli', 'physiologic arousal', 'avoidance fear'. 'Feeling the needle injected', they felt severe dental fear. 'My muscles become tense' of Symptoms they feel dental fear was the most frequent Sex affects avoidance fear, physiologic arousal, fear of specific dental stimuli and dental fear. Femal feel more its than male. The time since last dental clinic visit affects physiologic arousal, fear of specific dental stimuli and dental fear. Group do not visit the dental clinic within a year feel more its than others. Conclusions: To reduce dental fear in university students, it is necessary to make them visit dental clinics frequently and dental staffs consider their sex. Therefore, Department of dental hygiene and dentistry must be added the management of dental fear of the curriculum. In addition, it must be emphasized that to visit dental clinics frequently for university students.

Objective : The purpose of this study is to investigate the relationship among the degree of symptoms of posttraumatic stress disorder (PTSD) and social support, stress coping strategies, and self-esteem in patients with PTSD. Methods : A total of 48 patients meeting DSM-5 criteria for PTSD and 48 normal controls were recruited for participation in this study. We evaluated subjects using the Clinician-Administered PTSD Scale (CAPS), Hamilton Anxiety Scale (HAM-A), Hamilton Depression Scale (HAM-D), Rosenberg Self-Esteem Scale (RSES), Multidimensional Scale of Perceived Social Support (MSPSS) and The Ways of Stress Coping Questionnaire (SCQ). We analyzed data using an independent t-test and Pearson's correlation analysis. Results : In PTSD patients, total CAPS scores showed a significant positive correlation with HAM-A and HAM-D scores and a significant negative correlation with MSPSS scores. RSES scores showed a significant positive correlation with MSPSS and SCQ scores. MSPSS scores showed a significant negative correlation with PTSD avoidance and numbing and HAM-D scores. SCQ scores showed a significant negative correlation with PTSD avoidance and numbing. Conclusion : These results revealed that the better the stress coping strategies and social support, the lower the degree of symptoms in patients with PTSD. In addition, it was found that the higher the social support and self-esteem, the lower the degree of depression and anxiety. Therefore, in the treatment process, it seems important to identify and correct the self-esteem, social support system, and stress coping strategies of patients with PTSD.

This paper presents a new collison-free trajectory problem for SCARA robot manipulator. we use artificial potential field for collison detection and avoidance. The potential function is typically defined as the sum of attractive potential pulling the robot toward the goal configuration and a repulsive potential pushing the robot away from the obstacles. In here, end-effector of manipulator is represented as a particle in configuration space and moving obstacles is simply represented, too. we consider not fixed obstacle but moving obstacle in random. So, we propose new distance function of artificial potential field with moving obstacle for SCARA robot. At every sampling time, the artificial potential field is update and the force driving manipulator is derived from the gradient vector of artificial potential field. To real-time path planning, we apply very simple modeling to obstacle. Some simulation results show the effectiveness of the proposed approach.

Objectives : The purpose of this study was to identify correlation of personality preference, and achievement goal orientation, academic self-efficacy, test anxiety in selecting college students who majored in dental hygiene. This study also provides a basic data regarding personality for education of dental hygiene students. Methods : 192 students of S college who majored in dental hygiene were asked to answer the MBTI GS form, academic self-efficacy scale, achievement goal orientation scale and test anxiety scale during the month of May, 2009. The total of 160 copies were analyzed. MANOVA, independent-sample t-test were conducted. Results : 1. Looking at distribution of personality preference type of the students, extroversion type (63.1%) was more than introversion type(36.9%), sensing type(87.5%) was more than intuition type(12.5%), thinking type(54.4%) was more than feeling type(45.6%), judging type(59.4%) was more than perceiving type (40.6%) 2. In subscale of achievement goal orientation, performance approach level was higher in extroversion type than in introversion type. Performance avoidance level was lower in extroversion type than in introversion type. However, other preference personality type didn't show any significant difference in subscale of achievement goal orientation. 3. Academic self-efficacy was higher in extroversion type and thinking type than in introversion type and feeling type. There wasn't any significant difference between judging type and perceiving type, sensing type and intuition type. 4. In subscale of academic self-efficacy, confidence was higher in extroversion type than in introversion type. Task difficulty preference and self-regulated efficacy were higher in thinking type than in feeling type. 5. There wasn't any significant difference between personality preference type and test anxiety. Conclusions : Professor should find out difference between students through using information of preference personality and develop a teaching strategy that can encourage strength and make up weakness of each students.
