The name of the department is not only a means of notifying the existence of the department, but also acts as an important indicator that includes the overall curriculum, specialization strategy, student management, and employment of the department. The importance of the department name, which is a collection of internal and external public relations, has emerged greatly, but the existing research related to this is insufficient. Therefore, in this study, the terminology used in the names of beauty departments at two-year colleges and four-year colleges nationwide is surveyed year by year to contribute to the establishment of developmental goals that the department should aim for and a systematic analysis for curriculum reform. As a result of the study, in 1994, 7 schools (41.18%) had the most skin care departments, and in 2005, 2013 and 2020, 'Beauty' was 50 cases (21.55%), 67 cases (28.03%), and 92 cases (34.20%), respectively. Through this study, it is possible to analyze the overall trend of the beauty industry, and it is expected that it will be used as basic data when promoting a department name change or opening a department in the future.

In this article, a fairly extensive literature review was conducted to depict the current status of academic motivation and its developmental trend among Korean adolescents. The focal factors were perceived competence and autonomy which have been considered as major determinants of academic motivation. Theoretical frameworks adopted were self-efficacy theory, expectancy-value theory, and self-determination theory. Empirical studies conducted in Korean educational settings during the past decade were the target of the literature review. Results of the literature analysis revealed that, in general, there was a decreasing tendency in perceived competence from elementary to middle school which followed by a slight increase after entering high school. Similar trend revealed in the development of autonomous motivation, in that middle and high school students' intrinsic motivation levels were lower than that of the elementary groups. The amotivational tendency was increased as the grade level proceeded toward high school, which requires attention from educators. Discussion was followed in an attempt to provide plausible interpretations for this undesirable current status of Korean adolescents' academic motivation and to suggest implications for possible remedial actions both in pedagogical perspectives and students' well-being.

Objective: To evaluate whether co-culture of oocytes on vero cell monolayers from Day 0 (Day 0 group) after egg retrieval results in an increase in developmental capacity such as fertilization rate, embryo quality, blastulation and clinical pregnancy rate compared with co-culture of oocytes from Day 1 (Day 1 group). Methods: Sperms were treated with Hams F-10 supplemented with 10% human follicular fluid (hFF). Vero cells for co-culture were prepared in TCM-199 with 10% FBS. Oocytes were co-cultured from Day 0 and fertilized oocytes were co-cultured from Day 1 on vero cell monolayers in DMEM with 10% and 20% hFF, respectively after egg retrieval. On day 1, 2 and 5, fertilization rate and grade of embryos and blastocysts were evaluated. Results (fertilization rate, cleavage rate, grade of embryos and blastocysts and pregnancy rate) were considered statistically significant when p value was less than 0.05 using t-test and $x^2$. Results: In sibling oocytes of same cycles, no differences were found in fertilization rate (94.6 vs. 91.4%), cleavage rates (94.6 vs. 91.4%), embryo grade (on day 2 and 3) and blastulation (65.6 vs. 57.0%) and their grade. In different oocytes of different cycles (patients), no differences were found in fertilization (79.8 vs. 78.3%), cleavage rates (77.7 vs. 76.4%) and blastulation (56.0 vs. 45.3%), but pregnancy rate was higher in the Day 0 group than in the Day 1 group (60.0 vs. 42.9%). Conclusions: This study revealed that the embryonic development capacities were not affected by the different co-culture time in the sibling oocytes of same cycles. Although no statistical significance, because of small size of study, there was a trend for higher pregnancy rates in Day 0 group compared to Day 1 group in different oocytes of different cycles.

Purpose: This study aims to evaluate and prospect for current research trend and developmental perspectives via analyzing recent biomaterial coated-implants study. Materials and methods: To investigate each subject respectively, several biomaterials that are using for implant surface coating were set as 'keywords'. By these keywords, major research groups in each subject were chosen, and research trend of them was analyzed. Trend of In vivo studies that examined selected biomaterials were analyzed to evaluate commercial potential. Results: The collagen research accounted for 40% of total implant study, which was the highest, and fibronectin, BMPs (bone morphogenetic proteins) and RGD (Arg-Gly-Asp) peptides followed, which were ranked in descending order. Furthermore, figures of all four research subjects were also increased with time, especially a sharp increase in RGD research. According to the results of major research group, collagen that was combined with other organic and inorganic biomaterials was mostly examined, rather than using collagen only. Major research groups investigating BMPs mostly focused on rhBMP-2. In animal studies, collagen was used as resorbable membrane in guided bone regeneration (GBR) or drug carrier, while BMPs were used with bone graft materials or coating material for titanium implant surface. Conclusion: There is not consistency of results even in identical subjects research field. Many studies are ongoing to optimize combination between mechanical surface treatment and biomaterials such as extracellular matrix component and growth factors.

This study investigates the developmental conditions of functional clothes for the elderly. First, preceding studies and relevant web sites were analyzed along with a survey of commercial functional elderly clothes in Korea. A KIPRIS patent information database was used to study registered and disclosed patents and utility models in order to analyze patent application trends in relevant fields. Patents were searched by year of application from 1990 to 2013. Keywords used for searching included 'senior, aged, and elderly'. Among collected data, overlapping and irrelevant data were excluded to select 162 cases for analysis. Details of analysis are annual patent application trends of functional elderly clothes, topic analysis, shape and characteristics. An examination of commercially available functional clothing products for the elderly indicated that most of products were developed in the form of inner wear or protective clothing for seniors who have bodily discomfort. An annual patent application of functional elderly clothes showed slight fluctuations; however, there was an overall increase. For patent topics, technologies related to secretion and excretion were the most at 47 cases total (29%), followed by 23 cases (14%) on biometric information technology. However, the development of relevant technologies seems necessary in the future as therapeutic function and fiber technologies gradually stagnate.

The latest trend in the automotive industry demands the development of high stiffness car bodies and the securement of inter-system performance for low vibration and noise vehicles. This demand, however, conflicts with need for light weight design and greater fuel efficiency, thus raising the importance of optimization design to satisfy both developmental goals. We chose two European medium sedans, which has gasoline engine and diesel one, to elucidate the noise characteristics of diesel passenger cars, whose sales have been increasing in both Korea and Europe. In the present study a systematic experiment was conducted to analyze the noise characteristics in diesel cars. we made it possible for differentiating car management according to customer demand while allowing for improved commercial feasibility. it was possible to improve interior noise by 2 dB(A) on average sound pressure level. As a result, by 4% higher on articulation index(AI).

2007년 노동부의 사회적기업 육성법을 시행하면서 정부의 인증을 받으 사회적기업들이 탄생하였고 이는 기존의 국내 기존의 사회적기업의 개념과 정의에 새로운 국면을 탄생시켜 관련 연구들이 새롭게 시작되게 되었다. 또한, 시간이 지날수록 학계, 정부, 민간의 사회적 기업(Social Enterprise)에 대한 관심이 커지고 있으며, 앞으로도 정부의 적극적인 지원으로 인해 사회적 기업이 많이 늘어날 것이다. 하지만, 사회적 기업이 추구하는 가치에 대한 정확한 이해와 이를 바탕으로 한 지속적인 발전(Sustainable Development)에 대한 연구는 부족한 것이 현실이다. 본 연구에서는 사회적 기업이 추구하는 사회적 가치와 경제적 가치, 환경적 가치 등에 관한 개념을 국내외 문헌 고찰을 통해 폭넓게 제시하며, 아울러 이제 막 태동하기 시작한 사회적 기업에 대한 확장적 사고를 통해 지속적인 발전이 가능한 사회적 기업의 바람직한 모델에 관해 논의하고자 한다. 이를 위해 선진 해외 사회적 기업의 다양한 모델 사례를 다양하게 제시하고, 이를 통해 우리나라 사회적 기업이 추구해야 할 시사점을 제시하고자 한다. 본 연구는 사회적 기업의 가치에 대한 폭넓은 시각에 기초하여 기업가적인(entrepreneurial) 사회적 기업의 다양한 모델을 제시함으로써 우리나라 사회적 기업의 경쟁력을 강화하는데 기여할 수 있는 의미 있는 연구이라고 판단된다.
