본 연구는 iOS GUI 디자인의 변화에 함의된 어포던스의 변화와 이를 통한 어포던스 간의 관계를 고찰하는 것을 목적으로 하였다. 선행연구를 통해 다양한 어포던스 개념을 도출하고 연구에 사용될 6가지 어포던스(본능적, 행동적, 반성적, 명시적, 메타포적, 패턴 어포던스)를 선정하고 iOS의 GUI 디자인 변화를 어포던스 관점에서 고찰하여 다음과 같이 그 결과를 도출하였다. 첫째, iOS GUI 디자인의 본능적 어포던스는 이미 충분한 반성적 어포던스를 형성하고 있어 이를 과감히 생략하거나 제거하고 있으며 이로 인해 보다 명확한 명시적 어포던스의 제공이 가능하다. 둘째, iOS의 행동적 어포던스와 패턴 어포던스는 사용 경험의 누적으로 인해 반성적 어포던스를 형성하고 있으며 이를 통해 새로운 패턴 어포던스를 형성하고 있으며 이는 또한 메타포적 어포던스의 기반 영역으로도 활용된다. 셋째, iOS의 플랫 디자인을 어포던스 관점에서 고찰해 본 결과, 본능적 어포던스의 감소로 인하여 시각적 표현 상의 제약이 줄어들게 되어 화면 공간의 여유, 컬러 변화의 자유, 명시적 어포던스의 제공 등이 가능하게 된 것도 그 원인 중 하나임을 알 수 있었다. 또한 본 연구에서는 본능적 어포던스가 사용경험 누적에 따라 반성적 어포던스를 형성하고 이는 메타포적 어포던스의 기반 영역으로 활용되며, 본능적 어포던스의 제거나 감소는 보다 명확한 명시적 어포던스를 제공하고 있으며 이를 통해 새로운 패턴 어포던스가 생성되는 어포던스 간의 상호작용에 의한 관계 변화 또한 고찰할 수 있었다.

Intelligence is thought to be related to interaction rather than a deep but passive thinking. Interactive tangible media "iT_Media" is proposed to explore these issues. Personal robotics is a major area to investigate these ideas. A new design methodology for personal and emotional robotics is proposed. Sciences of the artificial and intelligence have been investigated. A short history of artificial intelligence is presented in terms of logic, heuristic, and mobility; a science of intelligence is presented in terms of imitation and understanding; intelligence issues for robotics and intelligence measures are described. A design methodology for personal robots based on science of emotion is investigated. We investigate three different aspects of design: visceral, behavioral, reflective. We also discuss affect and emotion in robots, robots that sense emotion, robots that induce emotion in people, and implications and ethical issues of emotional robots. Personal robotics for the elderly seems to be a major area in which to explore these ideas.

In this study, I have researched the theories about Gibson's real affordance and Norman's perceived affordance which are central fact of affordance, And I have examined the context of affordance in smart-phone interface which was consist of affordance and signifier with viewpoint of amalgamation of Gibson & Norman. The results of this study are as follows; The first, Gibson's real affordance is a physical space in ubiquitous environment that interact through the behavioral space is composed with physical space and electronic space. Norman's perceived affordance is mediated to electronic space and signifier makes a behaviroal space which provide the clue of interaction. The second, signifier can be categorized into visceral, behavioral and reflective signifier based on three brain actions which are visceral, behavior, and reflection. Through the categorization, we can grasp that behavioral and reflective signifies generate visceral signifier. The third, the context of affordance in smart-phone has the structure of circulation. The structure of circulation is as follows: Real affordance makes the perceived affordance, the perceive affordance makes the signifiers and the signifiers make new real affordance. This study could provide the theoretical basis for using signifier in smart-phone interface design.

Purpose: According to current guidelines, perioperative chemotherapy is an integral part of the treatment strategy for advanced gastric cancer. Randomized controlled studies have been conducted in order to determine whether perioperative chemotherapy leads to improved R0 resection rates, fewer recurrences, and prolonged survival. The aim of our project was to critically appraise three major studies to establish whether perioperative chemotherapy for advanced, potentially resectable gastric cancer can be recommended on the basis of their findings. Materials and Methods: We analyzed the validity of the three most important studies (MAGIC, ACCORD, and EORTC) using a standardized questionnaire. Each study was evaluated for the study design, patient selection, randomization, changes in protocol, participating clinics, preoperative staging, chemotherapy, homogeneity of subjects, surgical quality, analysis of the results, and recruitment period. Results: All three studies had serious shortcomings with respect to patient selection, homogeneity of subjects, changes in protocol, surgical quality, and analysis of the results. The protocols of the MAGIC and ACCORD-studies were changed during the study period because of insufficient recruitment, such that carcinomas of the lower esophagus and the stomach were examined collectively. In neither the MAGIC study nor the ACCORD study did patients undergo adequate lymphadenectomy, and only about half of the patients in the chemotherapy group could undergo the treatment specified in the protocol. The EORTC study had insufficient statistical power. Conclusions: We concluded that none of the three studies was sufficiently robust to justify an unrestrained recommendation for perioperative chemotherapy in cases of advanced gastric cancer.

Objective: An experiment was conducted to determine the effect of algae-based antioxidant containing Se yeast (EconomasE^®) on the growth performance, visceral organ weight, meat quality, and oxidative stability of broiler chickens. Methods: Nine hundred sixty, day-old male broiler chickens (Cobb, 43.97±0.55 g) were divided into three dietary treatments and allocated into 12 deep litter pens in a completely randomized design giving 4 replicate cages for each treatment. Three dietary treatments were: i) control (CON, basal diet with sufficient nutrient), ii) vitamin E (VitE, basal diet supplemented with 100 IU VitE), and iii) Algae-based antioxidant containing Se yeast (EcoE, basal diet supplemented with 0.2% algae-based antioxidant containing Se yeast: EconomasE^®). Maize soybean meal based basal diets were formulated to meet or exceed the nutrition requirement for broiler chickens. Chickens were fed ad-libitum experimental diets during the 42 days experiment period. On days 21 and 42, body weight and feed intake were measured to calculate the feed conversion ratio of the chickens. Intestine and visceral organs were measured together with meat quality and oxidative stability on days 14 and 42. Results: Chickens fed with EcoE showed improved (p<0.05) growth performance, meat quality, and higher (p<0.05) oxidative stability compared to the chicken fed on CON. Moreover, broiler chickens fed with EcoE showed similar (p<0.05) growth performance with better (p<0.05) meat quality and higher oxidative stability compared to the broiler chickens fed VitE (p<0.05). Conclusion: The algae-based antioxidant containing Se yeast can be supplemented into commercial broiler diets as a substitution of VitE while maintaining growth performance with enhancing meat quality and oxidative stability of the broiler chickens.

Objective: The present study examined the effects of exogenous emulsifiers and multi-enzyme supplementation into a low energy density diet on growth performance, visceral organ parameters, blood metabolites, ileal morphology, and nutrient digestibility in broiler chickens from hatch to 21 days. Methods: One hundred and sixty-eight one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to 24 pens and each pen was assigned to one of four dietary treatments to give six replications with seven chickens in a cage. Dietary treatments were: i) positive control with standard energy level (PC); ii) negative control with 100 kcal/kg lower energy of the standard level (NC); iii) NC diet supplemented 0.05% calcium stearoyl-2 lactylate as an emulsifier (NC+E); and iv) NC diet supplemented with both 0.05% calcium stearoyl-2 lactylate and 0.05% multi-enzyme (NC+E+M). Corn and soybean meal-based control diets containing vegetable oil were formulated to meet the Ross 308 nutrition specification. Chickens were fed ad-libitum with the treatment diets and sampling was conducted on day 21. Results: Our results revealed that emulsifier and multi-enzyme supplementation into NC diets improved (p<0.05) feed efficiency of the broiler chickens compared to the broiler chickens fed NC diets from hatch to 21 days. Supplementation of emulsifier and multi-enzyme into NC diet improved (p<0.05) nutrient digestibility of the broiler chickens. However, emulsifier and multi-enzyme supplementation into diet did not influence (p>0.05) visceral organ weight, blood metabolites, and intestinal morphology in broiler chickens fed NC diets. Conclusion: Supplementation of emulsifier and multi-enzyme in the NC diet would support improving growth performance in young broiler chickens with improved feed efficiency and increased nutrient digestibility thereby curtailing the negative impact of energy reduction in the diets.

Purpose: The aim of the study was to determine the effects of a community based participatory program in obese middle-aged women. Methods: One-group pretest-posttest design was used. The subjects were 35 middle-aged women. Data were collected at public health centers in Chungcheongnam-Do from March to May, 2013. To evaluate the effect of the program, physiological indexes(body mass index, skeletal muscle mass, body fat mass, visceral fat area) and health behavior indexes(dietary practice guidelines score, moderate physical activity, drinking frequency) were measured. Analysis was performed using a Wilcoxon Signed Rank Test. Results: After the program, physiological indexes (BMI, BFM, SMM, VFA) and health behavior indexes (dietary guidelines scores, frequency of physical activity, drinking frequency) were significantly improved. Conclusion: The community based participatory obesity program by public health centers is considered to be effective. Therefore, greater effort is needed for better participatory program development of several health promoting fields, and more research is needed in order to examine a continuous effect.
