Since SNS has gained its popularity as the means of diffusion of Hallyu, this study aims to examine the relationships between SNS use and Hallyu. In particular, this study explored how the use of SNS as a tool for obtaining information about Korean entertainment influence Chinese attitude toward Hallyu and Hallyu contents In doing so, the study conducted the case of Sina Weibo, the most leading SNS in China. The survey questionnaire was administrated to college students who use Sina Weibo in China. Two hundreds forty one surveys were included in the final analysis. The result indicated that Sina Weibo use is strong predictor influencing attitude toward Hallyu and Hallyu contents. The more students use Sina Weibo to get Korean entertainment information the more they have positive attitude toward Hallyu contents and acceptance of Hallyu in their life. In addition, the study found that attitude toward Hallyu(in terms of acceptability) depends on the level of activity in the Sina Weibo among college students in China. In other words, the passive users (e.g. lurking) are more likely to adopt Hallyu rather than active users (e.g. people who are more likely to retweet Korean entertainment information on Sina Weibo or click 'like). Based on these findings the implications, limitations and directions for future studies are discussed.

Biophysical and biochemical processes through which crops interact with the atmosphere have been simulated using land surface models and crop growth models. The Noah Multi Physics (MP) model and the CERES-Rice model, which are a land surface model, and a crop growth model, respectively, were used to simulate and compare rice growth and evapotranspiration (ET) in the areas near Haenam flux tower in Korea. Simulations using these models were performed from 2003 to 2012 during which flux measurements were obtained at the Haenam site. The Noah MP model failed to simulate the pattern of temporal change in leaf area index (LAI) after heading. The simulated aboveground biomass with the Noah MP model was underestimated by about 10% of the actual biomass. The ET simulated with the Noah MP model was as low as 21% of those with the CERES-Rice model. In comparison with actual ET measured at Haenam flux site, the root mean square error (RMSE) of the Noah MP model was 1.8 times larger than that of the CERES-Rice model. The Noah MP model seems to show less reliable simulation of crop growth and ET due to simplified phenology processes and assimilates partitioning compared with the CERES-Rice model. When ET was adjusted by the ratio between leaf biomass simulated using CERES-Rice model and Noah MP model, however, the RMSE of ET was reduced by 30%. This suggests that an improvement of the Noah MP model in representing rice growth in paddy fields would allow more reliable simulation of matter and energy fluxes.

현재 중국에는 55개의 소수민족이 있으며, 그 인구총수는 6,700만을 초과한다. 중국정부는 특히 70년대 후반서부터 소수민족에 대한 일연의 보호정책을 쓰고 있으며 다수민족인 한족에 대하여 엄격히 실시하는 1가구 1자녀 정책에서도 소수민족을 제외하고 있다. 이에 따라 소수민족의 증가는 현저하게 늘었다. 그러나 전반적인 인구학적특성으로 보면 소수민족은 아직 후진성을 면하지 못하고 있다. 조선족이라고 일컫는 재중 우리교포는 한족을 포함하여 중국내 어느 민족과 비교하여도 인구학적으로 독특한 위치를 차지하는 경우가 많다. 예를 들어 인구증가율은 가장 낮으며 어느민족보다 앞서서 1970년대 중반에 이미 대치수준 이하의 출생률에 도달한 것으로 믿어지고 있다(Han 등, 1988). 문맹률은 최하이며 대학수업율은 최고로 높다(장(張), 1984). 사망률은 전소수민족중 가장 낮고 평균 수명은 가장 길다(Dowdle, 1984). 이렇게 재중 조선족은 인구학적으로 가장 선진적이기 때문에 1자녀 정책에 대한 수용 준비가 다른 민족보다 앞서 있다고 할 수 있겠다. 물론 조선족은 소수민족에 속하기 때문에 1자녀정책에 구애될 필요가 전혀 없다. 따라서 조선족 가정에서 1자녀만을 낳겠다는 서약을 하여 이른바 '독생자녀증'을 영수하면 이것은 한족의 경우와 달리 자율의사에 따른 것이라 할 수 있을 것이다. 이 논문에서는 다음 두가지를 다루기로 하겠다. 즉, 조선족이 인구학적으로 보아 딴 민족에 비하여 어떤 위치에 있으며, 또 중국의 중요인구정책인 1가정 1자녀제에 어떻게 반응하고 독생자녀증을 어떻게 수용하느냐 하는 것이다. 이 밖에 중국의 대소수민족 인구정책의 앞날에 대하여도 약간의 전망을 하여볼까 한다.스와 여기에 사용되는 신호 방식을 논의하고 있다. 그 외에도 전광 통신망 운용에 필요한 라우팅 및 파장할당 방법과 OXC를 이용한 그물형 망에서의 보호 및 복구에 대한 연구도 활발히 진행되고 있다.rotene 보충군에 비하여 유의적으로 높았으며 retinyl acetat와 B-carotene 보충군 사이에는 유의적인 차이가 없었다.3.17%로 가장 양호하였으나, 양파망과 염화비닐판을 수직으로 놓은 것은 각각 1.52%와 1.61%로 비교적 저조하였다. 수정 후 40일째부터 90일째까지 측정한 부착치패의 경과 일수에 따른 각장의 성장은 $SL=184.44e^{0.0335X}(r^2=0.9861)$의 회귀직선식으로서 나타났다. 중간육성 시험에서 수심별 성장을 분석한 결과, 비단가리비 치패는 저층보다 표층이 각장 5.92mm, 전중량 6.07g 정도 더 빨리 성장하였다. 시간으로 하여 l 주 44 시간을 기준으로 측정하면 통상질환관리 18.56시간, 지역사회 보건관리 5.67 시간, 모자보건 및 가족계획 5.52 시간, 사업 운영관리 및 지도 4.10시간, 지역사회 조직 및 개발 3.05 시간, 보건정보체계 개발 및 수집 2.94 시간, 사업계획 수립 2.89시간의 순으로 나타났다. 5) 보건진료원의 업무영역별 수행 소요시간의 상판판계를 살펴보면 지역사펴 조직 및 개발을 위 해 소요한 시간은 사엽계획 수립 소요시간 및 보건정 보체계 관리 소요시간과 순상관관계를, 사업 계획 수립 소요시간은 지역사회 보건관리, 모자보건 및 가족계획 관리 소요시간 및 보건정보체제 관리 소요시간과 순상관관계를 나타냈다. 또한 통상질환관리 소요시간은 지역 사회 조직 및 개발, 사업계획 수립, 지역사회 보건관리와 모자보건

Resistance to Phytophthora blight (Phytophthora capsici Leonian) of commercial cultivars of Capsicum pepper in Korea were evaluated from 2008 to 2010. In 2008 and 2009, the cultivars were tested for resistance to the Pc003 isolate collected in Youngyang, Gyeongbuk province. In 2010, the selected cultivars in the previous years were tested by inoculating with 3 isolates obtained from the pepper plants in Miryang in Gyeongnam province, Youngyang in Gyeongbuk province, and Goesan in Chungbuk province. A continuous variation in resistance from highly resistant to susceptible was observed among the commercial pepper cultivars. It was also noted that some cultivars, although their names were initiating with 'Yeokgang' or 'PR' meaning Phytophthora resistance, were very low in resistance or susceptible. When the resistant cultivars selected in 2008 and 2009 experiment were inoculated with the 3 isolates, all the commercial cultivars except a rootstock, 'Tantan', succumbed to the exceptionally virulent Pc005 (Miryang) isolate. Pc002 (Goesan) was a little more virulent than Pc003 (Youngyang). A few cultivars resistant to Pc003 (Youngyang) were severely infected by Pc002 (Goesan). Significant interaction in analysis of variance suggested the differential interactions between cultivars and pathogen isolates. Strategies to breed cultivars having high level of resistance to the highly variable pathogenic fungus, Phytophthora capsici, were discussed.

Speeding is a major cause of traffic accidents that affects the safety of pedestrians and harms drivers and their families, property and mental health. However, most researches on speeding behavior have been conducted by survey method, so the relationship between cause and effect is not clear. The reliability of the research cannot be carefully examined because most researches involve retrospective methods. It is clear that conducting experimental research is important for overcoming these limitations, but it is impossible to perform tests with real cars in real traffic situations due to the inability to control situational factors (e.g., other vehicles, traffic signal) which affect participants' behavior. A car simulator experiment was designed and the theory of planned behavior was applied to the experiment. Each participant was grouped and assigned to either high speeding intention group or low speeding intention group according to their levels of speeding intention and analyzed the difference of driving behavior indexes between two groups. The results revealed statistically significant differences between two groups on driving speed, speeding frequency, and accelerator pressure deviation. Finally, the limitations and the implications of this study were discussed.

With the development of big data processing technology, the potential value of healthcare big data has attracted much attention. In order to realize these potential values, various research using the healthcare big data are essential. However, the big data regulatory system centered on the Personal Information Protection Act does not take into account the aspect of big data as an economic material and causes many obstacles to utilize it as a research purpose. The regulatory system of healthcare information, centered on the primary purpose of patient treatment, should be improved in a way that is compatible with the development of technology and easy to use for public interest. To this end, it is necessary to examine the trends of overseas legal system reflecting the concerns about the balance of protection and utilization of personal information. Based on the implications of the overseas legal system, we can derive improvement points in the following directions from our legal system. First, a legal system that specializes in healthcare information and encompasses protection and utilization is needed. De-identification, which is an exception to the Privacy Act, should also clearly define its level. It is necessary to establish a legal basis for linking healthcare big data to create synergy effects in research. It is also necessary to examine the introduction of the opt-out system on the basis of the discussion on the foreign debate and social consensus. But most importantly, it is the people's trust in these systems.

The government has switched the purpose of housing policy, from the 'housing supply' to 'housing welfare', with the Housing Laws established in 2015 under evaluation that resident stability and resident standard were improved. But, as 'affordable' housing is gradually decreasing, residential environment has become more poor. Residential environment is a basic element for the child safety, health, and better education. This study explored that the poor resident environment had effect on the child, figured out the situation on housing poverty of domestic child and searched the situation of the residential policy of domestic and foreign child. The main results are as follows. First, the poor resident environment of childhood has a bad effect on the physical health, mental health, academic achievement and cognitive development. Second, 1.29 million children (11.9%) are living in condition of housing poverty below minimum resident standard and are concentrated in certain areas. Third, the policy on housing poverty of domestic child is almost absent and focuses on the elderly, young people. this study discussed political and practical solutions based on these research results. On the basis of these research results, as policy suggestions we proposed housing policy making based on the UN Convention on the Rights of the Child, evidence-based housing policy enforcement and, residential policy suggestions under the responsibility of central government, and as practical suggestions community working as the subject and related agency's solidarity from prevention activity of housing poverty and child advocacy point and we discussed way for issue and analyzed related laws, policies, commitments.

The Korean government recently announced greenhouse gases (GHG) emissions reduction target as 30% of 2020 business as usual (BAU) emission projection. As carbon emissions trading is widely used to achieve reductions in the emissions of pollutants, this study deals with the sectoral allocation of initial carbon emission permits in Korea. This research tests the effectiveness of a variety of allocation rules based on the bankruptcy problem in cooperative game theory and hybrid input-output tables which combines environmental statistics with input-output tables. The impact of initial emission permits allocation on economic growth is also analyzed through green growth accounting. According to the analysis result, annual GDP growth rate of Korea is expected to be 4.03%, 4.23%, and 3.67% under Proportional, Constrained Equal Awards, and Constrained Equal Losses rules, respectively. These rates are approximately from 0.69% points to 0.13% points lower than the growth rate of 4.36% without compulsory $CO_2$ reduction. Thus, CEA rule is the most favorable in terms of GDP growth. This study confirms the importance of industry level study on the carbon reduction plan and initial carbon emission permits should reflect the characteristic of each industry.

The purposes of this study is to identify the professional knowledge of the three elementary teachers for science-gifted students in teaching method. All teachers have received in-service program in gifted education, and have been recommended by their colleagues. Two teachers have instructed the gifted for more than five years, one teacher have instructed the gifted for one year and the general students for eleven years. For for this study, each teacher's lesson plans were collected, videotapes were recorded during lessons, and in-depth interview for each participant were conducted. All recoded data were transcribed and analyzed. Some unique characteristics of teaching method for the gifted were identified from the class instruction of participants. They had knowledge of teaching model for the gifted, especially Renzulli's three pod enrichment model. And they mainly used the materials developed by KEDI for the gifted. Also they had capability to be able to reconstruct them, but their lesson plans did not be realized well in their class. Some implications from findings of this study were suggested, such as teaching methods to improve the quality in the classes of the gifted in science.

There are two strands for considering tile relationships between education and technology. One is the viewpoint of 'learning from computers' and the other is that of 'learning with computers'. In this paper, we call mathematics education with computers as 'computers and mathematics education' and this computer environments as microworlds. In this paper, we first suggest theoretical backgrounds ai constructionism, mathematization, and computer interaction. These theoretical backgrounds are related to students, school mathematics and computers, relatively As specific strategies to design a microworld, we consider a physical construction, fuctiionization, and internet interaction. Next we survey the different microworlds such as Logo and Dynamic Geometry System(DGS), and reform each microworlds for mathematical level-up of representation. First, we introduce the concept of action letters and its manipulation for representing turtle actions and recursive patterns in turtle microworld. Also we introduce another algebraic representation for representing DGS relation and consider educational moaning in dynamic geometry microworld. We design an integrating microworld between Logo and DGS. First, we design a same command system and we get together in a microworld. Second, these microworlds interact each other and collaborate to construct and manipulate new objects such as tiles and folding nets.
