  • 북한의 전술탄도미사일(TBM, tactical ballistic missile)에 대한 방공 분야 연구는 빠른 속도로 변화하는 전장 환경을 고려해야 한다. 아군 유도탄의 표적 재지정 연구는 동적인 전장에 대한 대응뿐만 아니라 아군 방어 자산의 효과적인 운용을 가능하게 한다. 현재까지 진행된 연구는 의사 결정 과정에서 중요한 역할을 하는 TBM의 명중 확률이 고정된 값이기 때문에 실시간 전장 상황을 대변하지 못한다. 따라서 본 연구는 실시간 전장 환경을 고려한 명중 확률을 기반으로 의사 결정을 내리는 표적 재지정 알고리즘을 제안한다. 제안 방법론은 랜덤 포레스트와 무빙윈도우(moving window) 기법을 사용하여 현재 TBM의 위치 및 속도 정보로 TBM의 예상 궤적을 예측하는 궤적 예측 모형을 포함한다. 예상 명중 확률은 궤적 예측 모형과 유도탄의 시뮬레이터를 통해서 계산할 수 있으며, 계산된 명중 확률은 유도탄에 대한 표적 재지정 알고리즘의 의사결정 기준이 된다. 실험에서는 TBM 궤적 예측 모형에 사용한 방법론의 타당성이 검증되었으며, 표적 재지정 의사 결정 과정에서 제안된 모델을 통해 명중 확률을 사용하는 것의 우수성이 확인되었다.

  • Amended Water Quality Environment Preservation Law enacted that the areas where nonpoint pollution is serious can be designated as Nonpoint Source Management Region. According to Section 54 of Water Quality Environment Preservation Law, corresponding watersheds are areas where runoff from nonpoint pollution source may deteriorate river and lake water quality, residents' health and property, and ecosystem. The criteria are as followings; i) where nonpoint source contribution result in or will result in significant ecological destruction, iii) national or local industrial complexes and cities having population greater than one million where nonpoint source managements are necessary, iv) where specific measurement is necessary because of its geological and stratigraphic characteristics. In this research, detailed designation criteria was developed reflecting current nonpoint source management situation and its discharge characteristics. Depending on the result, target regions were also suggested. In additions, it will be desirable that the target regions are prioritized considering institutional execution availability, stakeholder's agreement, and connection with existing nonpoint source pollution management measures.

  • This study was conducted to provide sustainable measures for conservation and management to protect valuable natural/ecological resources, offer differentiated quality assurance services for eco-tourism products, and explore measures for eco-tourism certification/designation systems. To achieve its goals, the study discussed domestic and overseas trends and literatures that concern eco-tourism certification/designation system and investigated case studies that were presently operational. A group of experts and a group of non-experts were surveyed separatedly to investigate the awareness of the national eco-tourism certification/designation system. The results from the investigation indicate that Europe, since the late 1990s to early 2000, has actively introduced a system that establishes and operates a dedicated institution, and European members have created a cooperation framework to formulate international partnerships and develop standardized assessment benchmarks to adhere to the goals of the system, the period for certification was designated from one year to five years, and renewals were granted based on periodic monitoring and reassessment. In Korea, from early 2000, the Ministry of Culture, Sorts and Tourism and other organizations have certified product quality and assessed travel products and national park tour programs. The certification period was established to be set between one and three years, and the vast majority were not reassessed. Upon investigating the results for awareness of national eco-tourism certification/designation system, a high number of respondents agreed with the need to establish a eco-tourism certification/designation system (90% of respondents), and the respondents cited eco-tourism quality assurance, conservation of value, means to maintain established institutions, and environmental education and information as reasons for needing a certification/designation system. In Korea, a certification/designation system for the eco-tourism industry is presently in operation, but the system regulates target institutions based on their characteristics. Therefore, this study proposes its suggestions via various categories, including designated institutions, designated purpose, designated subjects, designated organization, laws, regulations, and incentives.

  • Ecotourism has been attracting much attention as an example industry that can vitalize local economy markets and preserve natural resources. Implementation of 'Ecotourism Designation System' is under consideration to provide ecotourism products that can both emphasize the original meanings of ecotourism and ensure stronger trust from customers than ever before. This research introduced the direction, principles, subjects, and assessment indicators by subjects in terms of implementing the system and proposed fundamentals for both designation assignment and score calculation. In the face of implementing such a system in Korea, the investigation sought subjects whose target areas and programs are in need of examination. For assessment criteria by subjects, six assessment indicators were selected in the end for ecotourism sites, including: (1) the value of natural/ecological preservation (2) facility's ecological design (3) understanding both the environment and local culture (4) systems connecting local communities for cooperation (5) long/short term preservation and maintenance strategies/plans (6) willingness to further develop ecotourism and cooperative platform. In addition, seven assessment indicators were selected for program assignments, including: (1) the value of natural/ecological preservation (2) minimization of environmental effects (3) expansion of environmental understanding (4) sharing the local culture (5) vitalizing local connections and economical activities among communities (6) securing and maintaining professionality among human resources (7) odds of continuation, creativity, and aptness to improve programs. After considering the pros and cons of both categorizing system and yes/no system, implementation of categorizing system for the short term and yes/no for the long term were suggested, followed by additional suggestions of a score calculation system for each system. The official implementation of the 'Ecotourism Designation System' is scheduled for launch in 2013 after the trial operation in 2012. The assessment indicators and fundamentals suggested in this research, considering judgment, must be improved via systematic and practical methods through the trial operation.

  • 본 연구는 훼손지에 적용된 국립공원 특별보호구 제도가 탐방로의 토양과 식생에 미치는 효과를 확인하기 위해 실시되었다. 북한산 국립공원 내 일반 탐방로(개방 탐방로)와 특별보호구로 지정되어 16년 동안 출입이 금지된 탐방로(폐쇄 탐방로)의 토양의 용적밀도, 수분, 총 질소, pH, 유기물 함량을 측정하고, 지면피도를 조사하여 개방 탐방로와 폐쇄탐방로의 토양 및 식생상태를 비교분석하였다. 일반 탐방로의 토양은 탐방로 주변 식생지대의 토양에 비하여 용적밀도가 증가하고 수분과 총 질소, 유기물 함량이 감소하여 훼손을 확인하였으나, 폐쇄 탐방로의 경우, 토양의 용적밀도, 수분, 총 질소, pH, 유기물 함량이 주변 식생지대와 유의한 차이가 나타나지 않아 탐방로 폐쇄로 인한 생태적 회복을 확인하였다. 지면피도의 경우, 일반 탐방로에서 지면식생과 낙엽의 피도가 낮고 나지와 암석의 피도가 높아 훼손을 확인하였으나, 폐쇄 탐방로에서는 낙엽 암석 나지 피도가 회복되었고, 식생피도는 산림 환경피해도 등급을 적용하였을 때 제한적인 회복이 이루어진 것으로 나타났다. 이 연구를 통하여 특별보호구 지정을 통해 훼손지의 회복이 가능하나, 토양이 식생에 비하여 더 빠르게 회복됨을 알 수 있었다. 훼손지의 특별보호구 지정은 대상지의 회복특성에 대한 과학적 근거를 기반으로 판단할 필요가 있으며, 특별보호구 제도의 효과성을 높이기 위해 대상지의 생태적 사회적 가치와 중요성을 고려한 세분화된 특별보호구 선정 및 관리 기준이 필요하다.

  • The purpose of this study is to investigate various information relating to research on the dimensions of clothing used in the sale of products via the internet that used to target global SPA((Specialty Store Retailer of Private Label Apparel) brands sold in Korea. A total of 12 SPA brands including seven global SPA brands and five national. SPA brands were surveyed in this study. Brands were chosen net sales and consumer preferences the last three years. In all SPA brands, literal size designation such as S, M, L and numeric size designation such as 0, 2, 4 or 32, 34, 36 etc. were mixed, but in case of Jean, the size codes mark waist circumference were dominant. European size codes were more common in case of European brands while literal codes were more dominantly used for American size codes with in the US brands. By reviewing the measurement information of the body and product size, the product measurement methods of UNIQLO, FOREVER 21 and TOPTEN were much more accountable and excellent than other brands. However, most of the others didn't offer proper information such as pictograms or figures about measurement methods relating body sizes and product sizes. In addition, most of global SPA brands offered size conversion chart which consumers could reference, however of none of the national SPA brands offered a conversion size chart on their website. Regardless of the type of clothing, the coverage of clothing size was higher than in global SPA brands such as H&M GAP compared to national SPA brands. In particular, 8seconds did not present apparel size ranges that fit consumers' individual clothes sizes.

  • Objective : The goal of this study was to investigate the characteristics of early maladaptive schemas (EMSs), and associated neurocognitive functions as seen in visitors for military designation process. Methods : This retrospective study included 111 males aged 18 to 24 years among three groups: 41 visitors for military designation process (VMD), 21 patients with obsessive-compulsive disorder (OCD), and 49 healthy subjects. We collected the results of the Young Schema Questionnaire, Symptom Checklist-90-Revised, three neurocognitive tests as well as their clinicodemographic data. We analyzed the differences in EMSs between these three groups, and the correlations among the identified EMSs and neurocognitive performances within the VMD group. Results : Compared with both the OCD and healthy groups, the evaluation of the VMD group showed significantly higher scores in mistrust/abuse (F=6.4, p=0.002), vulnerability to harm (F=6.6, p<0.0001) and negativity/pessimism schema (F=7.3, p<0.0001), even when controlling for depression scores and levels of education. These three schemas also exhibited significant negative correlations with the score of Stroop test with r ranging from -0.34 to -0.44. Conclusion : These findings suggest that people who are likely to have difficulties adjusting to living in a military life may have psychological vulnerabilities related to certain EMSs. Further studies are warranted to test the clinical potentials of these findings, such as a treatment target and a predictor factor.

  • Recently, attention for health promotion is rising. Alcohol is widely consumed among adults. About 1/3 of people 15 years of older enjoy drinking alcohol. Some 80% of them drink a half or more bottle of soju each time. Regular excessive drinking of alcohol may cause various problems. WHO(1990) reported that social problems such as divorce, unemployment, and financial difficulties ; psychological problems such as melancholy, suicide, and drug abuse ; physical problems such as cirrhosis, lung cancer, high blood pressure, stroke, and sterilization. The patients with liver disease are estimated to be 628,000. Approximately, 12,000 persons are dying by chronic liver disease and cirrhosis each year. Among the people of 15 years or older, persons dependent on alcohol are estimated to be 1,480,000. This study suggests policies to reduce the consumption of alcohol for planning for health promotion. Limitations of sites and times of sales and designation of sellers, designation of sites prohibiting drinking, limitation of alcohol sales promotion, and restrictions on advertisement can be inaugurated. Increase of price through the raise of tax and taxation of promotion cost. Education of high risk groups such as soldiers, pregnant women, and the youth can be introduced. Provision of alternative socialization programs instead of drinking. Some approaches on target groups were suggested.
