  • In spite of the rapid growth of mobile multimedia contents market, most of the customers experience inconvenience, lengthy search processes and frustration in searching for the specific multimedia contents they want. These difficulties are attributable to the current mobile Internet service method based on inefficient sequential search. To overcome these difficulties, this paper proposes a MOBIIe COntents Recommender System for Movie(MOBICORS-Movie), which is designed to reduce customers' search efforts in finding desired movies on the mobile Internet. MOBICORS-Movie consists of three agents: CF(Collaborative Filtering), CBIR(Content-Based Information Retrieval) and RF(Relevance Feedback). These agents collaborate each other to support a customer in finding a desired movie by generating personalized recommendations of movies. To verify the performance of MOBICORS-Movie, the simulation-based experiments were conducted. The results from this experiments show that MOBICORS-Movie significantly reduces the customer's search effort and can be a realistic solution for movie recommendation in the mobile Internet environment.

  • In the course of magnetic study on several perovskite-type oxides, A2Fe(Ⅲ)BO6 (A = Ca, Sr, Ba and B = Sb, Bi), we have observed a strong irreversibility in their dc-magnetizations. When the structural data and the Mossbauer spectra are considered, such an irreversibility is to be associated with some competitions between the nearest-neighbors (nn) and the next-nearest-neighbors (nnn) in their magnetic sublattices. Particularly, the Mossbauer spectra indicate that Sr2FeBiO6 of cubic perovskite-structure is apparently well ordered crystalline compound. Nontheless this antiferromagnet shows a magnetic property which resembles that of a spin-glass. The strong history dependence is observed below 91 K and the irreversible magnetic behavior is also observed from the measurement of hysteresis loops at 10 K after zero-field-cooled (zfc) and field-cooled (fc) processes. Considering the nn and the nnn superexchanges of almost same order in ordered perovskite, it is proposed that there exists a competition and cancellation of antiferromagnetic and ferromagnetic superexchange between the nearest-neighbors and the next-nearest-neighbors, thus introducing a certain degree of frustration.

  • The purpose of this study was to understand the influence of the level of social emotional competence of college students on their achievement emotion, life satisfaction, and academic achievement. To this end, a survey was conducted with 301 college students in the Busan and Gyeongnam areas of Korea in 2019. The students were divided into high, medium, and low levels according to social emotional competence. Then, on the basis of these divisions, their achievement emotion, life satisfaction, and academic achievement were compared with oneway ANOVA. The results indicated that students with high social emotional competence had higher average scores in positive achievement emotion: enthusiasm, hope, and pride; lower average scores in negative achievement emotion: anger, anxiety, shame, frustration, and boredom; and higher average scores in life satisfaction, and academic achievement compared to the group with middle and low social emotional competence. Based on the results, this article discusses considerations and recommendations for follow-on studies. It also highlights the need for social emotional competence education in Korea against the backdrop of intense pressure on students to perform well academically and a culture where emotion is not freely expressed.

  • This paper represents a partial outcome of a doctoral research undertaken at the University of Tokyo, Japan. The doctoral research looked on the phenomenology of innovation and its implications for the construction industry in Japan. This paper focuses on the perception of innovation by major Japanese construction clients and major Japanese construction firms. Among construction researchers innovation is a popular topic and no conference will miss covering the issue. After a period of very critical judgment on the ability of the construction sector to innovate and partially even frustration on the inflexibility of the sector, a much more positive attitude was taken. At present, most construction researchers would agree that the construction sector clearly is very innovative. That stands in contrast with how construction practitioners perceive their own sector. This paper presents the results of and empirical research in how construction clients and contractors in Japan perceive the issue of innovation. In fact the perceptions differ largely and give interesting insights on particularities of the Japanese construction sector and on the mismatch of clients and contractors perceptions.

  • This article is based on a research conducted from 2009 to 2012, on the political disputes in Thailand. During the data collections periods, it was common to hear the frustration, bitterness and anger, expressed by the Redshirts, especially those who lived in the northeast and northern regions. Coming from the said research, this paper will examine the relationship between emotions and rights. According to the sociology of emotions, there are connections between macrolevel social processes and the arousal of emotions. Emotions arising from macrostructural processes may affect individuals at the microlevel, prompting them into actions collectively. In addition, expressions of resentment and articulation for vengeance can be interpreted as the emotions related to the awareness of rights, which may include the rights to one's needs and the access to resources that fulfill such needs. It will demonstrate how emotions, political demonstrations and the increasing awareness of rights, are related.

  • Despite the important role of manganese (Mn) in cobalt-free, Ni-rich cathode materials, existing reports on the effects of Mn as a substitute for cobalt are not consistent. In this work, we analyzed the performance of cathodes comprised of Li(Ni1-xMnx)O2 (LNMO). Both beneficial and detrimental results occurred as a result of the Mn substitution. We found that a complex interplay of effects (Li/Ni mixing driven by magnetic frustration, grain growth suppression, and retarded lithium insertion/extraction kinetics) influenced the performance and was intimately related to calcination temperature. This indicates the importance of establishing an optimal reaction temperature for the development of high-performance LNMO.

  • This study was done to provide information which would lead to nursing care of the elderly being more holistically through an understanding of the phenomena of powerlessness based on the lived experience of powerlessness by the elderly, the meaning the elderly give to such phenomena, and what essence of powerlessness is. The methodology used in this study was Max Van Manen's phenomenological method based on the philosophy of Merleu-Ponty and a concerted approach was realized through the 11 steps suggested in the Van Manen's method. Data collection was done from March 2, 1995 to December 30, 1995. The subjects for this study were four elderly persons who lived with their families and who were over 60 years of age. Data were collected about the lived experience of the elderly, this researcher's experience of powerlessness, the linguistic meaning of powerlessness, idioms of the word or a feeling of powerlessness, and descriptions of powerlessness in the elderly as they appeared in the literature, are works, and phenomenological literature. All data were used to provide insights into the phenomena of powerlessness. Data about the experience of powerlessness by the elderly were collected through open interviews, participation, and observation. In the analysis of the theme of this study, the aspects of the theme, powerlessness in the elderly were clarified, thereby abstracting and finding meaningful statements by the elderly about their feeling of powerlessness, and then those significant statements were expressed as linguistic transformations. The summarized findings from the study are as follows : 1. Five meanings of powerlessness in the elderly were defined. 〈weakness〉, 〈dependence〉, 〈frustration〉, 〈worthlessness〉 and 〈giving up〉. 2. 〈Weakness〉 means that the elderly experience, not only their aging but also, their becoming weak and the loss of physical function frequently caused by diseases. 〈Dependence〉 means that the elderly experience dependence without any influence from the surroundings and that elderly patients who are hospitalized lose their autonomy, follow entirely their doctor's prescriptions, use aid equipment and directions, and depend only on those things. 〈Frustration〉 means that the elderly experience the loss of their roles from the past, there by feeling that there is no work for them to do anymore and therefore feel unable to do anything. 〈Worthlessness〉 means that the elderly experience the feeling of losing their social roles from the past, having no financial ability, thereby being a burden to their children or the people around them, and therefore regarding themselves useless. 〈Giving up〉 means that the elderly experience the feeling of closeness to death in the final stage of their lifetime, lose hope to be healed from their disease, and recognize the incontrollability of their own body. 3. From a general view of the meaning of the theme the powerlessness in the elderly-the most essential meaning of the theme is the 〈sense of loss〉. For the elderly are experiencing a sense of loss in the situation of being elderly and therefore being often hospitalized. Brief definitions of the five phenomena could be 〈weakness〉 meaning the loss of physical strength, 〈dependence〉 the loss of mentality caused by disease and hospitalization, 〈frustration〉 and 〈worthlessness〉 the loss of social performance caused by the loss of social functions from the past, and lastly 〈giving up〉 the loss of the controllability of such situations of aging and suffering disease. In light of the discussion above, it is understandable that the hospitalized elderly experience powerlessness not only as it related to their diseases but also to their normal aging, and this related to other characteristics of being elderly means that the 〈sense of loss〉 is the very essence of their powerlessness. 4. While most cases are of the normal elderly experiencing powerlessness in relation to their social network, cases of elderly who are hospitalized are of those experiencing powerlessness in relation to the loss of their physical desire. 5. The findings discussed above can serve as guidelines for nurses who take care of the ill elderly who are hospitalized and that can provide cues to appropriate nursing service, recognizing that the subjective experience of the objective age of the elderly is so important. Nurses can provide highly qualitative nursing service, based on their deep understanding of the suffering of the elderly due to feelings of powerlessness.

  • 공자의 대동(大同)과 도연명(陶淵明)의 도화원(桃花源) 이후 중국의 유토피아 상상은 오늘날까지 지속되어 왔다. 이러한 유토피아 상상은 다양한 문학텍스트로 형상화되어 왔으며 이 작품들은 유토피아 상상을 구현하고자 하는 인간의 욕망과 좌절을 묘사하고 있다. 일반적으로 '도화원(桃花源)'은 동아시아적 유토피아의 표상으로 인식되고 있다. 도화원(桃花源)은 노자의 소국과민을 바탕으로 하는 무정부주의 성격이 강한 유토피아이다. 도화원(桃花源)은 통치계급이 존재하지 않는 세상이다. 그러나 공자가 이상향으로 생각했던 대동(大同)세상은 덕치(德治)를 전제로 상상 가능한 세상이다. 청말(淸末)에 이르러 강유위(康有爲)는 "대동(大同)서"를 저술하고 이 가운데 제도를 통해 현실화된 유토피아를 제시하고 있다. 그리고 문학텍스트로 정전화 되었던 유토피아는 신해혁명 이후 오늘날 중화인민공화국에 이르기까지 문학 속의 '상상'을 일상의 '현실'로 구현하고자하는 실험이 계속되었다. 거페이의 "인면도화(人面桃花)"는 바로 그 실험의 지점에 대한 성찰적 보고서의 성격을 띠고 있는 것이다. 거페이의 "인면도화(人面桃花)"는 이러한 유토피아적 상상의 구현과정과 좌절을 묘사한 뛰어난 작품이라고 평가받고 있다. 또한 선봉파 작가로서 거페이는 "인면도화(人面桃花)"를 통해서 유토피아적 상상의 욕망과 좌절을 시지프스의 신화와 같음을 이야기하고 있으며 그 자체로서 유토피아는 끊임없는 생명력을 지니고 있음을 이야기하고 있는 것이다. 본 논문에서는 고대 중국 이후 지속되어온 유토피아적 상상을 현실에서 구현하고자 했던 흔적들을 문학텍스트 가운데서 탐색하고자 한다. 공자의 대동(大同)과 도연명(陶淵明)의 도화원(桃花源) 이후 21세기에 이르러 거페이는 작품가운데서 다양한 인물형상을 통해 전통적 유토피아를 실현시키고자 하는 욕망과 좌절의 과정을 묘사하였다. 작가는 그 좌절과 욕망의 과정이 바로 인간의 유토피아 상상의 생명력임을 이야기하고 있는 것이다.

  • This study was made to find out how stress affect on nutrition status of the college freshmen who were experiencing physical growth and development as well as drastic emotional change. 400 male and female freshmen in 4 year colleges were surveyed respectively through the health check-up procedure for college entrance in February, In order to find out the stress in each group frustration, deprivation, lack of self efficacy, type A behavior and anxiety response were surveyed through 10 questions with total 40 points by assigning 4 points for each question. Diet Status was expressed by DDS (Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). 24-hrs recall method was used to find out the quantity of daily nutrient of EAR(estimated adquacy ratio) by KDRIs(Korean Dietary Recommended Intakes). Nutrition level was analyzed by Can-Pro for professionals (Korea Nutrition Association). And for the quality intake, percentage was calculated and MAR(Mean Adequacy Ratio) were produced. Highest point was obtained in the stress of anxiety with the total 40 score of 30.20, and the scores were 29.79, 28.67, and 28.39 for deprivation, type A behavior and frustration respectively. There was no difference of blood components in accordance with stress type. Stress type was divided into less sensitive group and highly sensitive one and the relationship with the blood nutrient status was observed. The difference of blood component and blood pressure in sensitive and highly sensitive groups was observed in deprivation and anxiety. The index of blood pressure(p<0.05), hemoglobin(p<0.01), HDL-cholesterol(p<0.05), and Fe(p<0.05) was high in the deprivation of sensitive group. Blood pressure and hemoglobin was high in type A of sensitive group(p<0.05). And the contents of blood triglyceride was high in the anxiety of sensitive group(p<0.001) The result of nutrition intake analysis according to stress type showed that there was low intake for energy, riboflavin, and niacin. When the degree of deprivation was high there was a lack of riboflavin intake and there was no significant difference of nutrition intake in lack of self efficacy, type A behavior and anxiety response. Thus, it is necessary for colleges to educate the students to maintain mental stability through various programs and activities after catching a kind and extent of the stress college students we meeting with like the confusion of value system, open heterosexual relationship, and the employment difficulties linked with political uncertainty and economic recession.
