The objectives of this study were to assess physical habitat suitability of fish species for different life cycle stages and to suggest appropriate ecological stream flows in a Bokha downstream reach. A dominant species of Zacco platypus was selected as the study fish of which three stages of spawning, juvenile and adult in life cycle were considered into assessment. The stream hydraulic environment was calibrated with HEC-RAS before the PHABSIM simulation. The hydraulics of flow velocity and depth were used to estimate Weighted Usable Area (WUA) by multiplying respective habitat suitability indices with stream area. Overall the WUAs tend to be great in gentle slopes with relatively shallow water depth regions. Maximum WUAs, ie, candidate for ecological flow rates were 1 m³/s, 7 m³/s and 8 m³/s for the respective spawning, juvenile and adult stages of Zacco platypus. Since the ecological flow rates for juvenile and adult stages appeared to be is greater than the abundant flow rate (3.67 m³/s) for the study reach, additional water supply may be needed but should be cautious to avoid the spawning period of Apr through May from the stream water management perspective.

Major industrial accidents in which workers die due to fires or explosions while working at chemical substance handling workplaces continue to occur. Among the major industrial accidents that occurred between 2005 and 2021, the accident status by work situation and equipment was analyzed. Through analysis, it was confirmed that storage, reaction, and piping facilities were the main causes of the accident, and a self-checklist for each facility was developed. Verification was conducted through the supply and use groups to evaluate the suitability of the use, duties, and items of the self-checklist. The user group showed higher satisfaction than the supplier group for all three suitability of use, job, and item. In particular, since the inspection items of the self-checklist were organized around the cause of the accident derived through the analysis of actual accident cases, the satisfaction level was high in all groups. It is expected that the self-checklist developed through this study will be useful not only for large companies but also for small and medium-sized chemical industries that lack professional manpower.

우리나라는 수요 곡물의 대부분을 수입으로 의존하기 때문에 주요 곡물 수출 국가의 재배 면적과 생산량 예측을 통해 식량안보를 증진시킬 수 있다. 특히, 밀 주요 수출국인 우크라이나를 대상으로 재배지역의 변화 전망을 파악하는 것이 장기적인 밀 수급에 대한 미래 정책 결정에 도움을 줄 수 있다. 본 연구에서는 작물의 기후적합도를 예측하는 Fuzzy Union 모델을 사용하여 과거 기후조건(1970~2000)에서 우크라이나 지역의 밀의 기후적합도를 평가하고자 하였다. 우크라이나 통계청으로부터 밀 생산량과 재배면적 통계자료를 수집하였다. 또한, 위성영상을 활용하여 작물의 재배면적과 수량에 대한 공간자료인 EarthStat 자료를 수집하였다. 모델로 계산된 기후적합도와 밀 관측지점과 비교하여 임계값을 설정하였다. EarthStat 자료와 실제 관측자료를 비교한 결과 일정 지역에서 재배면적과 수량이 일치하지 않는 지역들이 존재하였다. 과거 기후 조건에서 산출된 기후적합도의 경우에도 지역적인 차이를 보였다. 예를 들어, 우크라이나의 서북부 지역에서 0.8 이상의 높은 기후적합도의 분포를 보였으나 동남부 지역에서는 0.15 수준의 낮은 기후적합도를 보였다. 그러나, 기후적합도의 행정구역별 통계량과 실제 밀 재배면적과 생산량을 비교한 결과 일정 수준의 상관관계를 가졌다. 특히, 단위면적당 생산량과 기후적합도의 상관계수는 0.647로 중위 정상관을 나타냈다. 이러한 결과는 기후적합도를 활용하여 재배면적 추정 및 단위면적당 수량 예측이 가능함을 시사하였다.

여우 복원 사업이 시행됨에 따라 자연에 방사된 여우의 개체수가 증가하고 있어 앞으로는 여우 개체들이 다른 지역으로 분산되어 인간 생활 지역에서도 출몰할 것이다. 본 연구에서는 이에 따른 영향을 예측하고 대비하고자 여우의 서식지 적합성 지수(HSI)를 개발하였다. 문헌 조사를 통하여 주요 환경 변수를 추출한 뒤, GIS를 이용해 분석한 결과, 총 5가지의 적합 지수(Suitability Index, SI)를 구축하였다. 임상과 경사, 향, 수계 및 도로로부터의 거리가 주요 변수이며, 임상도에 2배의 가중치를 주어 산술 평균한 값이 HSI 결과이다. 전국자연환경조사 자료와 비교한 결과, 여우 좌표들이 평균 0.64의 HSI의 값을 가지는 것으로 나타나며, 0.53 이상일 때에 출현 확률이 높은 것으로 보인다. 본 연구 결과를 활용하여 여우의 분포를 사전에 예측하여 앞으로의 복원 계획의 기초 자료로 사용하거나 추후 환경영향평가 시 분포 파악 및 저감 방안 마련에 도움이 될 것으로 기대한다.

This study was conducted as a basic study to develop the HSI(Habitat Suitability Index) model of Pelophylax chosenicus based on the research on the ecological and habitat status of Pelophylax chosenicus and the literature research on the HSI model. The habitat variables of Pelophylax chosenicus are the altitude of the spawning pond, the habitat area, the distance from wetland, the soil(aptitude grade for paddy field), the place for eating such as paddy field and wetlands(land cover) and the distance from Predator(Lithobates catesbeianus) distribution area. Based on the existing literature of Pelophylax chosenicus, the results of field surveys and expert opinions, the SI(Suitability Index) model and HSI model were developed and applied to the site to examine the applicability of the HSI model. As a result of application, SI 4 and SI 5 with varying SI values seem to have a major influence on the HSI. In addition, it is considered that the HSI model is an arithmetic mean of SI models, which has a major impact on HSI. The HSI model can be an important basis for the habitat evaluation and restoration model of Pelophylax chosenicus. In particular, it is highly applicable to the selection and evaluation of alternative habitats for Pelophylax chosenicus.

As a initial methodological approach to rational land use planning in the county-level area, three types of land suitability classification techniques were examined from the viewpoint of their practical applicability through the case study of Seungju-gun area, Chonnam-province, Korea : major factors' criteria(method I ), principal component analysis( I ), and local monitoring( R( ). Each method has its strong and weak points as shown in Tab.-5. Therefore, when its practical application, there seem to be wide-range methodological selectivities from exclusive use of the best one to intermethodological combination of related ones In the beginning stage, intermethodological combination of all three types were tried to formulate the best solution possible. However, because of reliability problem of method R accrued from non- uniformity of evaluators'quality, only two methods( 1 , E ) were combined into a new evaluation method The applied results of the new combined method to case study area are shown in Fig.-2, 3 and 4.

During the negotiation and resolution of delay and disruption disputes on construction projects, the use and misappropriation of float, and the question of float ownership, are considered to be a major concern to those involved. Most practitioners and authors are of the opinion that it is an issue that should be clearly defined and addressed within the provisions of the contract. However, the terms "float" or "ownership of float" are rarely mentioned (if at all) in most of the standard forms of Australian construction contracts, giving little guidance to those involved as to how this issue should be addressed. In October 2002 the United Kingdoms Society of Construction Law (SCL) published a Delay and Disruption Protocol (the Protocol) that contains a suggested approach to the issue. The aim of this research was to obtain an Australian opinion of the suitability of the SCL's Delay and Disruption Protocols suggested approach to the issue of float and ownership of float for use by the Australian construction industry. Qualitative interviews were carried out with Australian construction industry experts experienced in the administration, negotiation, and resolution of delay and disruption disputes to obtain their opinions of the suitability of the SCL's proposed approach. Results indicate general confusion and uncertainty as to how the issue of float and float ownership should be addressed in general, with the SCL's approach adding further to that confusion.

The purpose of this study was to survey about the suitability of maternity dresses on the market and thus to contribute for the maternity dress makers to produce clothes which are ergonomic and wanted by customers. The chief designers of the two major maternity dress makers were questioned about design and production planning, and 195 subjects who had an experience of delivery within a year were questioned about their consumer behavior, preference, and body fitting. The suggestions according to the results of the questionnaire of maternity dress makers and customers were as follows : 1. The most important item, an one-piece dress should be produced a lot more than other items. 2. The designs of maternity dress should be more simple, sophisticated, and natural. 3. The colors of pastel tone rather than trendy colors should be used. 4. The materials of maternity dress should be washable and able to help pregnant women's activity. 5. The front patterns of maternity dress should have more ease than the back patterns have, to cope with increasing abdominal girth and bust girth.
