최근에 들어 웰빙(well-being)과 함께 로하스(LOHAS: Lifestyle of Health and Sustainability)란 개념이 급속도로 확산되고 있으며, 이를 만족하는 식품으로 친환경 농산물과 유기 가공 식품이 대두되고 있다. 여러 마케팅 조사에서도 친환경 농산물과 유기 가공 식품의 소비자 선호도는 상당히 높게 나타난다. 이러한 다양한 소비자의 요구에 맞춰 우리의 2세에게 더욱 안전하고 좋은 품질의 이유식을 제공하고 나아가 한계에 이른 '지구와 환경을 해치지 않는 지속가능 한 소비'를 유도하고자 업체들은 유기농 이유식을 개발하고 있다. 유기농 소비자 10명 가운데 7명은 최근의 웰빙 붐 때문에 유기농에 관심을 가지게 됐으며, 가격이 다소 비싸더라도 가족의 건강을 위해 친환경 농산물을 구입하는 것으로 나타났으며, 국내외를 막론하고 친환경 농산물과 유피 가공 식품의 시장 동향을 살펴보면 지속적으로 증가하고 있으나, 아직까지 일반 제품에 비해 미미한 수준이며, 국내는 인증 제도가 없으나, 유기 가공 식품표시기준에 따라 표시되고 있다. 일반적으로 이유식이라 함은 식품공전에서 영 ${\cdot}$ 유아용 곡류 조제식만을 말하지만 넓게 축산물의 조제유류, 영아용 조제식, 성장기용 조제식, 기타 영 ${\cdot}$ 유아식을 포함할 수 있으며, 유기농 이유식 제조 현황을 살펴보면 동결, 분무, 드럼 등의 건조와 퍼핑이나 Extruder를 통한 알파화로 원료를 가공하여 은 살균, 멸균, 균질, 혼합, 건조, 냉각, 포장 등의 다양한 공정으로 이루어진 분무건조나 유동층이나 연속식 과립기를 사용하여 분말이나 입자형 이유식을 생산하며, 동결 건조를 하여 열수를 가해 죽 상태로 먹을 수 있도록 한 제품, 데워서 떠 먹일 수 있도록 병조림이나 레토르트 유동식 제품, 바로 마실 수 있는 쥬스류, 두유류, 과자 등으로 생산하고 있다. 주된 메이저4사는 일동후디스, 남양유업, 매일유업, 파스퇴르유업으로 다양한 제품들을 생산하고 있으며, 두유를 위주로 한 정식품, 연세우유와 종근당건강, 다양한 다국적 기업들의 제품이 수입되고 있는 실정이다. 이유식 시장도 96년 하반기부터 정체를 보이는 상태다. 2002년도 이유식 시장은 약 1,300억원 규모로 업체들의 고가 신제품과 유기농 이유식 출시로 판매 금액은 소폭 상승하였으나 판매 수량은 큰 변동이 없다. 저출산에 따른 양육비 집중과 유기농 제품에 대한 저변이 크게 확산돼 베이비 웰빙은 어느 정도 예견된 일이거니와 이미 미국 등 선진국에선 유아에 그치지 않고 아동까지 유기농과 고급 원료를 사용한 고가의 웰빙 제품이 봇물을 이루고 있는 상황이어서 유아식 시장은 어느 때보다 경쟁이 치열할 것이며, 국내 식품 업체들이 너도나도 유기농 제품과 매장사업에 뛰어들고 있다. 유기 가공 식품의 지속적인 발전을 위해서 (1) 국내산/수입산 공통으로 인증 제도가 도입되고 원료 농산물뿐만 아니라, 모든 공정이나 공장에 대한 종합적 관리와 동일한 인증 표시가 이루어져야 한다. (2) 정부 부처의 이기를 타파할 수 있는 법정부적 기구나 대책이 필요하다. (3) 유기 가공 식품을 취급하는 업계에서는 기존 3%의 비의도적 혼입치의 고려나 상한선 재설정을 요구하고 진정한 유기 가공 식품으로 공정 경쟁한다. (4) 활발한 인증심사원의 교육과 배출로 인증이나 심사기관의 민간 이양을 적극 장려하고 국가관 상호 신뢰를 구축한다. (5) 각 소비자 단체나 소비자는 환경을 살리고 생명체의 공생이라는 관점에서 최선의 길이 유기농 제품임을 인식하고 소비하여 우리의 다음 세대에게서 빌려온 소중한 환경을 물려준다.

Recently, 357 water-friendly space were established near the main streams of the country through the Four Major Rivers Project, which was used as a resting and leisure space for the citizens, and the river environment and ecological health were improved. We are working hard to reduce the number of points and plan and manage the water-friendly space. In particular, attempts are being made to utilize mobile big data to make more scientific and systematic research on the number of users. However, when using mobile big data compared to the existing method of conducting field surveys, it is possible to easily identify spatial user movement patterns, but it is different from the actual amount of use, so various verifications are required to solve this problem. Therefore, this study evaluated the accuracy of estimating the number of users using mobile big data by comparing the number of visitors using mobile big data and the number of visitors using drone for Samrak ecological park located in the mouth of Nakdong River. As a result, in the river hydrophilic district, it was difficult to accurately estimating the usage pattern of each facility due to the low precision of pCELL, and it was confirmed that the usage patterns in the park could be distorted due to the signals stopped at roads and parking lots. Therefore, it is necessary to improve the number of pCELLs in the water-friendly space and to estimate the number of visitors excluding facilities such as roads and parking lots in future mobile big data processing.

This paper examines the rising value of social networked journalism and analyzes the case of a social news site based on the theory of networked journalism. Social networked journalism allows the public to be involved in every aspect of journalism production through crowd-sourcing and interactivity. The networking effect with the public is driving journalism to transform into a more open, more networked and more responsive venue. "wikitree" is a social networking news service on which anybody can write news and disseminate it via Facebook and Twitter. It is operated as an open sourced program which incorporates "Google Translate" to automatically convert all its content, enabling any global citizen with an Internet access to contribute news production and share either their own creative contents or generated contents from other sources. Since its inception, "wikitree global" site has been expanding its coverage rapidly with access points arising from 160 countries. Analyzing its international coverage by country and by news category as well as by the unique visit numbers via SNS, the results of the case study imply that networking with the global public can enhance news traffic to the social news site as well as to specific news items. The results also suggest that the utilization of Twitter and Facebook in social networked journalism can break the boundary between local and global public by extending news-gathering ability while growing audience's interest in the site, and engender a feasible business model for a local online journalism.

There is no willow riparian vegetation in Jeju Island, Korea. Instead, a genetically-isolated population of Adina rubella is found in some parts of the riparian system. We describe its syntaxonomy and synecology. A total of 27 phytosociological relev$\acute{e}$s were collected, 11 relev$\acute{e}$s from 91 sites and 16 relev$\acute{e}$s from the previously published relevant materials. Data were analyzed by traditional Braun-Blanquet method and multivariate PCoA (Principal coordinates analysis). New syntaxa are distinguished, Adinion rubellae all. nov. and its type association Tripogono-Adinetum rubellae ass. nov. with two subassociations, typicum and rhododendretosum poukhanensae. Adino-Rhododendretum poukhanensae Itow et al. 1993 was discarded owing to mismatch of syntaxonomy and syngeography of Adina and Rhododendron phytocoena. The alliance Adinion is Jeju's regional and partly ombrotrophic vegetation occurring in pothole and rock crevice where are independent on ground-water table. We also suggest a revised alliance, Rhododendrion poukhanensae Lee 2004 ex. hoc loco in Korean peninsula, as a corresponding syntaxon to Adinion, which completely differs from Phragmito-Salicion. Finally we pointed out that Adina phytocoena requiring an absolutely monitoring has been threatened by river maintenance project of local government.

This research outlined the factors influencing the business management success via analyzing a survey of business principles. The research process has been tested in comparison of both financial factors, which come out of objective data and non-financial factors so relevantly prioritized by combining these factors. In order to specify the factors, a check-list and analyzed essential features of category have been done with interviews and surveys. As consequently proceeding, the authors could deduce that non-financial but analytic factors such as business do-able, technician workability, compensation and benefits etc. play major roles in construction sector. The outcomes consider a construction business as fundamental human labor job as opposed to a manufacture business. On reasoning necessarily more objective research works to be done as developing this research's outcome, it is meaningful in suggesting the pivotal factors influencing the construction business management. Therefore, this research is expected to guide the direction to induce the improvement of business management to be done by further exemplary researches.

International Standardization in all technical area is gaining its momentum as its impact and implication over global trade is directly linked. The worldwide competition to secure a dominant position in the standardization process is ever growing over the years. In 2005, the International Technical Committee on Nuclear Instrumentation, which is a subunit of International Electro-technical Commission (IEC), was held in Korea under the auspices of MOST (Ministry of Science and Technology). Korea has adopted its Rule and Regulation as the National Standard. As a part of a link to National Mid-and Long-term Atomic Energy R&D Program of MOST, the technical development of a performance test for the radiation monitors was carried out under mechanical environment and electromagnetic immunity conditions. The characteristics of the radiation fields were also evaluated under the conditions and introduced to a techniques of performance test for the radiation protection instrumentation adopted IEC61526 standards and it's results was analyzed. We would like to share the experience gained in these efforts, failure as well as success, and to discuss the problems encountered and serious consideration to be taken into account in the future endeavor.

Background : Development of rapid drug susceptibility testing provides the opportunity for rapid identification of individuals with drug resistant tubercle bacilli, allowing selection of appropriate therapeutic regimens. Methods : A total of 502 drug resistant isolates were subjected to reverse blot hybridization assay to detect mutations within genes (rpoB, katG, inhA, and ahpC) associated with rifampicin (RMP) and isoniazid (INH) resistance. Results : Among the 264 RMP resistant strains ($RMP^R$) tested, the most prevalent mutation was the Ser531Leu seen in 121 strains (46%). The second common mutation occurred in 84 strains (32%) at codon 526. And 27 strains (10%) showed the mutation at codon 516. Among all 469 INH resistant strains ($INH^R$), the katG mutation was responsible for INH. The inhA mutation was present in 88 strains (19%). In 11 isolates (2%), coexisting of the katG and inhA mutations were identified. Reverse hybridization assay successfully detected over 80% of $INH^R$ and over 92% of $RMP^R$ among Korean isolates. CONCLUSION: Reverse hybridization was useful for rapid detection of $INH^R$ and $RMP^R$.

This study was Dental health determinants of elderly people. For this purpose, a questionnaire was done for 396 elderly people of 60 or more years old who have visited Seogwipo city public health center(branch) in Jejudo from May 27th to June 5th 2013 after they heard the intention of that investigation. Result of the most answers were 'normal' for the question asking the subjective status of teeth health of whom having more than 20 natural teeth as 73.3%; the most answers of whom with less than 19 natural teeth were 'bad' as 41.4%, which showed difference(p<0.05). The factors influencing the subjective teeth health were 4.3times higher in cases of women than men. The higher educational(high school or more)had they, the more monthly average income(2 million won or more) did they have, the higher was their subjective teeth health status(p<0.01). It is more important than anything that they reserve more than 20 natural teeth until they get old to keep and improve their oral and body health. In addition to that, the oral health project or oral health program to perform country-wide programs for free, consistent and systematic oral health examination and education should be planned.

This study investigated relative explanation of social support, ego-resiliency and stress coping strategies to help adaptive coping style of school-dropout adolescents under stress situation. To this end, 101 school-dropout adolescents were surveyed by visiting and requesting the outofschool youth supporting project, youth detention center, and adolescent protective and treatment facilities in Daejeon, Cheongnam, and Chungbuk. As analysis methods, descriptive statistical analysis, pearson's correlation, and hierarchical analysis were conducted and the research results are as follows. First, stress coping strategies showed positive relationship with social support and ego-resiliency. Second, a variable that showed greater explanation power for stress coping strategies was the environmental variable, the social support. Third, it was identified that there was greater explanation power when the environmental variable, the social support, and the personal variable, the ego-resiliency, were put in at the same time for stress coping strategies. According to the result, this study implies that schools, community, national policy effort and systemetic approach are required as well as improvement of personal coping capabilities in order to overcome difficulties school-dropout adolescents face.

The policy which encourages people to use cars on the road has been based on the growth of economy in Korea. It has also caused the concentration and overcrowding in Seoul. That's because the increasing number of people possessing cars interconnects with the urban development. The transportation is a derived demand; so many scholars have recognized the importance of understanding the relationship between urban land use and transport. Considering such importance, this study theoretically compared the developed urban land use-transportation models each other and outlined the particular models briefly. Models were categorized by 2 types; optimizing model and predictive mode. Predictive model is also defined by static model, entropy based model, spatial-economic model, and activity model. After studying models, we investigated other major cities in America. This process is the pre-step for transport policy assessment. Through careful literature review, we can finally develop the integrated land-use transportation model in Seoul metropolitan area. In addition, we will be able to deal the changes of traffic demand pattern under U-Society. Consequently, the results of this study can be applied to ITS projects in the future.
