  • Most of Korean broiler farms are constructed with vinyl houses. Such types of broiler farms might be cheaper in terms of cost, but poor in terms of environment condition. According to enlargement of broiler farm size, high value production systems or automatic facilities are introduced in this field. However, investment may not always guarantee the profit of the management. Therefore, it is necessary to undertake the investment analysis before decision making for the investment. Under the assumption that 870 Pyoung(≒$3.3㎡) of a broiler farm within 1,740 Pyoung(≒3.3㎡) of land is built with the producing capacity of 50,000 heads of chicken in a time. The total investment is calculated to be 600 million won(1,000 won≒$1.1), and out of them 58.1% is provided by the owner, 31.6% from the government loan, 5.8% from government subsidy, and 5.3% from other agencies or banks. The expected profit of the broiler farm is 64.6 million won(1,000 won≒$1.1) per year. The IRR calculated is 0.0808 which means that the rate to profit of this project would be 8.1%. This also means that for this investment the interest rate of the capital provided should be less than 8.1% per year. Considering that the current opportunity cost of the own capital is 8.5% this project is not so attractive for those who is going to build broiler farms mainly with their own capital. In other words this project would not be profitable, unless the average interest rate of the loans provided for this project is less than 8.1% per year.

  • Tooth is the most important element in esthetic consideration on facial area. Tooth alignment which is in harmony with gingiva, lips, and face is also key element. The purpose of this study was to give a clinical discipline for restoration of gingival contour, which contains a ratio of maxillary 6 anterior teeth, research for gingival contour etc., in case of rehabilitation of maxillary anterior teeth. 300 Dankook university dental school students ,who is their twenties and free from periodontitis, participate in this study. The result was from each 70 males and females who had normal occlusion and tooth alignment. Length, width and length/width ratio of maxillary 6 anterior teeth were 0.74-0.81 in male, 0.81-0.84 in female. There was significant difference between male and female. The most deepest position of gingiva in maxillary central incisor and canine was located in distal part of teeth and maxillary lateral incisor was middle portion. In maxillary central incisors, gingival line of the most deepest point appeared significant difference between male and female (p<0.01) whereas there was no difference in lateral incisors and canines. Distance between interdental papilla apex and the most deepest portion appeared significant difference between male and female. Distance of the deepest position of gingiva is statistically significant except maxillary central incisors and lateral incisors. Standard deviation and mean of the width of labio-lingual were measured in cervical area and there was a significant difference both male and female.(p<0.01) From this result, we could get the mean of maxillary anterior gingival line and these results have great value in clinical guidance in studying maxillary anterior teeth.

  • Our main concerns in this paper are with the several kinds of social economy organization in rural South Korea, in where social exclusion is likely to be prevalent over time. Approximately, there are 2,500~3,000 social economy organizations which have been set up from 1990s. Most of their operational social aims are either to offer jobs or to provide social services for the vulnerable social groups in rural communities. They have several normative principles as a social economy organization. But the two principles were less supported than the others; 1) the community's initiative and participation, and 2) sharing surplus with community. The social economy organizations are involved in various types of business. The greatest number of social economy organizations are doing businesses in agriculture and agro-industry. On average, their value of asset is worth of 300 million wons. They are indebted for 130 million wons, averagely. Their average surplus is 110 million wons. Most of them are small businesses. It is enough to say that the social economy is at an early stage in rural South Korea. The social economy is confronted with some challenges, as follows. Firstly, the social economy organizers should be based on the needs of community in both setting up a new social economy organization and managing businesses. Secondly, networking and cooperation between social economy organizations should be expanded and strengthened. Thirdly, the sound governance with public sector should be built.

  • Purpose: This study was carried out in order to examine organizational commitment in dental technicians and turnover intention level according to it, and to analyze its effects. Methods: A self-reported questionnaire survey was carried out by having convenience sampling as 200 dental technicians. An analysis of the collected data was computationally processed by using SPSS Win 19.0 program. An analytical technique was made by using statistical techniques such as frequency & percentage, t-test, One-way ANOVA analysis. The following are the analytical results of the collected materials. Results: In consequence of analyzing organizational commitment level in research subjects, there was a significant difference in the items for age, task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for organizational commitment level stood at 3.29, thereby having been indicated to be high. As a result of analyzing turnover intention level in research subjects, there was a significant difference in the items for task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for turnover intention reached 3.04, thereby having appeared to be relatively high. As for a correlation between organizational commitment and turnover intention, all variables were shown to have inverse correlation at a significant level. In consequence of conducting regression analysis in order to analyze the influence of organizational commitment upon turnover intention, a factor of having the most impact on turnover intention appeared to be normative commitment. The test value of the model was statistically significant. The explanation power about this was indicated to be 26.9%. Conclusion : In the above findings, the dental technicians are considered to need to be immersed in work with a sense of mission in performing job in charge, to strive to possibly have an opportunity of achievement and self-growth, and to perform a research and development in a manpower management strategy such as turnover prevention.

  • Background: This study is a quantitative evaluation of the influence of the mentolabial angle on perceived attractiveness and threshold values of desire for surgery. Methods: The mentolabial angle of an idealized silhouette male Caucasian profile image was altered incrementally between $84^{\circ}$ and $162^{\circ}$. Images were rated on a Likert scale by pretreatment orthognathic patients (n = 75), lay people (n = 75) and clinicians (n = 35). Results: A mentolabial angle of approximately $107^{\circ}$ to $118^{\circ}$ was deemed the most attractive, with a range of up to $140^{\circ}$ deemed acceptable. Angles above or below this range were perceived as unattractive, and anything outside the range of below $98^{\circ}$ or above $162^{\circ}$ was deemed very unattractive. A deep mentolabial angle ($84^{\circ}$) or an almost flat angle ($162^{\circ}$) was deemed the least attractive. In terms of threshold values of desire for surgery, for all groups, a threshold value of ${\geq}162^{\circ}$ and ${\leq}84^{\circ}$ indicated a preference for surgery, although clinicians were least likely to suggest surgery. The clinician group was the most consistent, and for many of the images, there was some variation in agreement between clinicians and lay people as to whether surgery is required. There was even more variability in the assessments for the patient group. Conclusions: It is recommended that in orthognathic and genioplasty planning, the range of normal variability of the mentolabial angle, in terms of observer acceptance, is taken into account as well as threshold values of desire for surgery. The importance of using patients as observers in attractiveness research is stressed.

  • This study focuses on online communities and the ritual conversations of users when participating in sharing activities. The study aims to understand the social and psychological phenomena that occur between users within the context of Erving Goffman's impression management theory. Case studies and a content analysis were conducted by collecting posts and comments related to fashion products in the sharing activities category on Naver Cafe "Family Sale." On the one hand, the study identified various disposition motives among givers, including a desire for recognition, self-expression, activation of the community, emotional sympathy, goodwill, play, and simple disposition. On the other hand, receivers' purchase motives included the need for a product, reciprocation based on a sense of belonging, play, gift-giving, and simple response. Analyzing the posts of givers and the comments of receivers of fashion products using impression management strategies and dramaturgical analysis, the study interpreted users' impression management and revealed propensities in fashion consumption: fashionability, conspicuousness, value orientation, and economic feasibility. Through ritual conversations, users managed to attain emotional stability on an individual level, while they reinforced collective bonds on a social level. They fulfilled their roles with their own narratives to achieve personal and collective goals in a non-face-to-face situations and non-monetary transactions. This study is significant in that it examines normative communication in an online community and user relationships to understand a recent phenomenon in the fashion industry.

  • 우리는 이 논문에서 존 스타인벡(John Steinbeck)의 "에덴의 동쪽(East of Eden)"에서 중요한 역할을 하고 있는 주인공 캐릭터인 Caleb Trask (또는 Cal)의 삶을 통해 얻은 교훈을 연구한 결과를 제시한다. Caleb의 삶은 자아, 타인, 그리고 사회와의 갈등을 극복하며 자아 발견의 과정에서 하나의 좋은 예를 제공해 주고 있다. 그는 여정 동안 자신의 감정을 인정하고 표현하는 법을 배우며 감정을 관리하고 이해하는 중요성을 강조한다. 욕망과 갈등에 직면하는 경우에는 지신이 생각하는 도덕적인 판단을 내려 행동하고, 윤리적 결정에 기반한 자기 결정의 중요성을 투명하게 보여주면서 자신의 진솔한 감정 표현과 수용은 감정 관리와 이해의 핵심 가치를 강조한다. 더불어 그의 이야기는 인간 관계에서 이해와 타협의 명확한 중요성을 강조한다. 우리는 이러한 주제에 대한 철저한 탐구를 제시하며, Caleb의 이야기에서 얻은 교훈이 어떻게 우리의 일상생활에 적용될 수 있는지를 고려한다. 이 논문에서 분석한 결과, 우리는 이러한 교훈을 어떻게 실제로 적용하고 실천할 수 있는지에 대한 통찰력을 얻을 것으로 기대한다.
