Qualitative consumption is a trend in the children clothing market and watching TV of childcare-entertainment reality programs are becoming popular. This study examines the watching degree of childcare-entertainment reality TV programs of parent buyer (30s) and potential buyer (20s) and we investigate their shopping orientation of children wear. We did the survey research of 200 consumers with SPSS statistical analysis including the review of internet news, paper, and books on children wear shopping orientation. The results are following: first, the longer the watching time of childcare-entertainment reality TV programs, the higher shopping orientation, such as following the fashion of child stars, and the higher the watching preferences on childcare-entertainment reality programs, the greater shopping orientation in following childcare-entertainment reality programs star when they are purchasing children's clothing. Second, potential consumers as well as parent consumers were affected by watching the childcare-entertainment reality programs. Watching childcare-entertainment reality TV programs could give the impact when they were shopping children's clothing because they wanted to follow the fashion of childcare-entertainment reality programs TV star. Accordingly, the exposure of the childcare-entertainment reality programs for children clothing is found to be positive to the both current and future consumers.

The purpose of this study was to evaluate the usability of the tablet PC-based Korean high-tech AAC(Augmentative Alternative Communication System) software. In order to develop an AAC software which is appropriate to Korean cultural/linguistic contexts and communication needs of the users, we examined the necessity and ease of use for the communication functions that are required in native Korean communication, such as polite expressions, tense expressions, negative expressions, subject-verb auto-matching, and automatic sentence generation functions, using a scenario-based user testing. We also investigated the users' needs, preferences, and satisfaction for the tablet PC-based Korean high tech AAC using a semi-structured and open questionnaires. The participants of this study were 9 special education teachers, 6 speech therapists, and 6 parents whose children had communication disabilities. The results of the usability testing of the tablet PC-based Korean high-tech AAC software presented positive responses in general, by indicating overall scores of above 4 out of 5 except in tense and negative expressions. The necessity and ease of use in the tense and negative expressions were evaluated relatively low, and it might be related to the inconsistent interface with the polite expressions. In terms of the user interface(UI), there were users' needs for clear visual feedback in the symbol selection and display, consistent interface for all functions, more natural subject-verb auto-matching, and spacing in the text within symbols. The results of the usability testing and users' feedback might serve as a guideline to compensate and improve the function and UI of the existing AAC software.

The preference of general adult on the forest and forest road was surveyed and analyzed for the development of forest therapy program. This study was conducted for the purpose of providing a basis for the development of more targeted-and differentiated-forest therapy program by analyzing the preference of general adult on the forest and forest road from 19 April 2014 to 30 June 2014 through on-line survey. The sample group of 613 adults has been used in practical analysis. Using SPSS 21.0, We looked at the preference differences of the forest and forest road according to the demographic characteristics(sex, age, education level, occupation and monthly income) through descriptive statistics analysis, frequency analysis, cross tabulation analysis, multiple response analysis. The seasonal preference was spring, autumn, any season, summer, winter in order and there was a significant difference according to one's sex, age, occupation and monthly income. There was a significant difference in the configuration of forest according to one's monthly income. The favorite type of forest as a place of forest healing program was natural recreational forest, healing forest, urban forest, park, school forest in order. There was no significant difference in the favorite forest type regarding to the distance to the healing place from one's residence in all cases. There was a significant difference in the type of forest according to one's monthly income. The most favorite configuration of forest road was gentle sloped road. Once walking into the forest for the purpose of healing, the favorite forest road length was 1.5~3 km, less then 1.5 km, more than 3 km in order and there was a significant difference in preference according to one's sex, age, education level and monthly income. We believe that the healing program should be differentiated from the general form of it according to one's sex, age, education level, occupation and monthly income as a result of this investigation of preference of general adult on the forest and forest road for the development of forest therapy program. In particular, we believe that the differentiated program should be offered according to one's age. We expect this analysis to be used as a basis for the development of forest therapy program.

This study investigates the effect of organic certification of apples on consumer preference in China as a way to support the expanded export of Korean apples to China. A choice experiment was designed to analyze the apple consumption in China. A total of 298 Chinese consumers answered the survey, and multinomial logit models were used to analyze the results. Organic certification was identified as an important determinant of consumer preference for apples in China, affecting both the evaluation and choice of country of origin. The results also indicated that Korean organic certification significantly increased the probability of Chinese consumers choosing Korean apples. Thus, organic certification by the Korean government should be strengthened to promote apple exports to China, plus the results of this study may provide useful information to promote agricultural product exports and improve the organic certification system.

추천 시스템의 대표적인 연구 중 하나인 콘텐츠 기반 추천 시스템 연구는 TV 프로그램이나 영화의 줄거리, 장르, 리뷰 등의 콘텐츠의 메타데이터를 이용한다. 그러나 이러한 연구들은 콘텐츠 관련 정보에만 의존할 뿐, 시청자의 프로파일과 콘텐츠의 정보를 함께 고려하지 않는다. 본 논문에서는 시청자의 프로파일 중 연령과 콘텐츠의 정보인 프로그램의 줄거리를 활용한 TV 프로그램 추천 시스템을 제안한다. 본 추천 시스템은 시청자를 연령에 따라 분류한 후, LDA 알고리즘을 이용하여 시청자의 시청 TV 프로그램의 줄거리를 분류된 나이에 따라 각각의 줄거리 토픽 모델로 생성한다. 이를 기준으로 시청자가 원하는 시간대에 방송되는 프로그램들의 줄거리 토픽벡터와 시청자의 선호도 토픽벡터의 유사도를 비교해 가장 유사도가 높은 TV 프로그램을 시청자에게 추천하는 방식이다. 본 논문에서는 연구의 효용성을 검증하기 위해 줄거리만을 사용한 경우와 줄거리와 연령을 동시에 활용한 경우를 비교 실험하였다. 실험을 통해 프로그램의 줄거리만을 사용한 경우보다 연령을 동시에 활용한 경우의 추천 시스템 성능이 개선된 것을 확인할 수 있었다.

본 연구는 중국의 3개지역 (Hebei, Shaanxi, Shanghai)에서 한 자녀가족정책이 둘째 및 셋째 아이의 출산에 미치는 영향을 헤져드(Hazard) 모델을 이용하여 분석하고 있다. 특히, 그 정책효과의 도시와 농촌간의 격차, 현재자녀의 성구조에 따른 격차의 연구에 중점을 두고 있다. 연구자료는 1985년에 완료된 제 1단계 중국의 출산력 심층조사 (In-Depth Fertility Survey in China)를 이용하였다. 이 분석은 해져드 모델에서 각 시점의 한 자녀정책 전인지 후인지를 나타내는 시간에 따른 변동변수(time-varying variable)를 설명변수중의 하나로 포함시키고 그와 더불어 그 변수와 도시/농촌 주거여부를 나타내는 변수와의 혼합변수 (Interactive term) 및 현존자녀의 성구조와의 혼합변수를 포함하므로써 가능하게 된다. 또한, 자녀의 사망력이 차후 출산력에 미치는 영향을 비슷한 방법으로 분석하였다. 연구결과로는 첫째, 둘째 및 셋째 아이를 출산할 확률에 있어서 도시와 농촌격차가 한 자녀정책 실시 이후 더욱 커졌다는 사실이다. 이러한 결과는 부모가 생각하는 자녀의 가치가 도시에서 더 많이 저하했음을 제시하거나 정부의 한 자녀정책이 도시에서 더욱더 엄격히 집행되고 있음을 시사하고 있다. 둘째, Hebei와 Shanghai에서는 남아가 없는 부부가 남아를 가진 부부보다 둘째 또는 셋째아이를 가질 확률이 훨씬 높게 나타났다. 한편, Shanghai에서는 한 자녀정책 이후 둘째아이의 출산률이 첫째아이의 성에 관계없이 매우 낮았다. 이는 전통적으로 내려오는 남아선호 성향이 아직 농촌지역에서는 강하게 영향을 미치고 있지만 도시지역에서는 강력한 정책집행이 이를 억누르고 있음을 시사하고 있다. 하지만 Shanghai에서도 첫째아이가 사망한 경우 그 아이가 남아였으면 죽은아이가 여아이였을 경우보다 둘째아이의 출산이 훨씬 더 빠르게 나타나고 있음을 볼 때 도시에서도 여전히 남아선호 성향이 잠재하고 있음을 간접적으로 보여주고 있다.

1990년대 후반부터 다양한 디지털 통신망을 이용하여 멀티미디어 컨텐츠 서비스가 가능하게 되었다. 하지만 멀티미디어 컨텐츠의 전달 및 이용을 위한 기반 구조들의 독자적 발전 및 다양한 통합 관리 시스템 때문에 멀티미디어 컨텐츠 표현 방식의 호환성, 네트워크 방식과 단말기 등의 잠재적인 문제점이 발생한다. 이를 위해서 현재 존재하는 기술 및 기반 구조들 사이의 연동을 통한 큰 멀티미디어 프레임워크인 MPEG-21이 진행 중이다. 본 논문에서는 현재 표준화 작업이 진행 중인 MPEG-21을 기반으로 하는 웹 (Web) 기반 테스트베드를 제안한다. 기본적으로 테스트베드는 서버(server), 클라이언트(client), DIA(Digital Item Adaptation)의 세 모듈로 구성된다. 서버의 역할은 멀티미디어 컨텐츠를 Digital Item(DI)의 형태로 생성하고, 클라이언트가 DI를 요구할 경우 DIA 모듈을 통해서 변환된 DI를 클라이언트에게 제공한다. DIA 모듈은 서버에서 동작되며 클라이언트로부터 요청된 DI를 분석하고 클라이언트로부터 전송된 환경 정보를 이용하여 클라이언트 환경에 적합하게 변환된 (adapted) DI를 생성하는 것이 주 기능이다. 클라이언트는 서버에 저장되어 있는 DI를 선택하고 사용자 선호도(user preferences), 터미널 능력(terminal capabilities) 등의 필요한 정보를 서버로 전송한다. 테스트베드에서는 스포츠 경기의 동영상, 정지 영상, 경기 내용, 역사를 기록한 파일 등의 DI를 이용한다. 표현 언어는 XML이며, HTTP 기반의 웹 환경에서 구동되도록 설계된다.

In order to check host plant diversity and to confirm the potential risk to be invaded, we documented host plant flora and plant part of C. pentagona, an invasive parasitic plant in field survey and induced parasitic infection by them in the laboratory experiment. Parasitic interaction(12% of total tree species) was found in twig and leaf of tree such as Quercus mongolica and Abies holophylla that was not developed into ligninfication. There were most host plant species belong to Compositae, but the species parasitic rate of family was higher in Cyperaceae, Polygonaceae and Leguminoceae. Through the inducible infection experiment with C. pentagona, all species except one species show parasitic interaction between host plan and C. pentagona. These result means that the limiting stage for invading area is dispersion process for invading other area in Korea. Infection plant part by C. pentagona was dominantly both shoot and leaf, rather than only leaf or only shoot. We found newly 12 families and 45 host plant species including 33 herbacious one and 12 woody one. Crop plant such as Setaria italica and 6 endangerd one such as Scrophularia takesimensis, especially the later rare endemic plant was to death by parasitic infection of C. pentagona. These results indicate that C. pentagona is potential risk to both wild and cultivated plant in Korea.

Alien species are known to threaten regional biodiversity globally, which has increased global interest regarding introduction of alien species. The Ministry of Environment of Korea designated species that have not yet been introduced into the country with potential threat as alert alien species to prevent damage to the ecosystem. In this study, potential habitats of Esox lucius and Maccullochella peelii, which are predatory and designated as alert alien fish, were predicted on a national basis. Habitat suitability was evaluated using EHSM (Ecological Habitat Suitability Model), and water temperature data were input to calculate Physiological Habitat Suitability (PHS). The prediction results have shown that PHS of the two fishes were mainly controlled by heat or cold stress, which resulted in biased habitat distribution. E. lucius was predicted to prefer the basins at high latitudes (Han and Geum River), while M. peelii preferred metropolitan areas. Through these differences, it was expected that the invasion pattern of each alien fish can be different due to thermal preference. Further studies are required to enhance the model's predictive power, and future predictions under climate change scenarios are required to aid establishing sustainable management plans.

This study selected blind spot areas for public transportation in four metropolitan cities including Busan, Daegue, Gwangju, and Daejeon. Then this study developed a nested logit model and analyzed the changes of mode choice behaviors after adopting rapid transit system using stated preference(SP) survey. As the study results, blind spot areas have more potential public transportation demand and tendency to shift to public transportation from autos than built-up areas. This study results can be utilized to evaluate demand changes for new rapid transit system in a circular expressway and an arterial highway connecting CBD and surrounding areas. The study results also can be utilized to analyze the potential public transportation demand in the surrounding areas.
