  • 국토교통부와 환경부의 물관리 일원화로 인해 국민들의 물관리 및 물환경 보존에 대한 관심이 고조되고 있다. 기존의 단순 유출 및 비점오염원 관리를 위한 장치형 시설 및 함양지의 확대에서 유역 전반의 건전한 물순환 체계 구축으로의 물관리 패러다임이 변화하고 있다. 이에 힘입어 유역 전반의 물관리에 대한 필요성은 지자체별 조례를 통해 기준을 확립하고 있다. 하지만 건전한 물순환을 위한 도시별 물관리 기준이 통일되지 않아 도시별 목표가 각기 다르고 대도시를 제외하고는 정량적 목표가 전무한 현실이다. 본 연구에서는 지자체별 물순환과 관련한 연구 및 조례를 정리하여 수변 지역의 도시를 대상으로 개발 이후에도 탄력적인 물관리가 가능한 물순환 목표를 설정하고, 이를 달성할 수 있는 정량적인 방안을 강우의 저장과 침투를 통해 제시하였다. 대상지의 전체 강우 분석을 통해 합리적인 수준의 물순환 목표를 설정하였고, 저영향개발 기법을 통해 최초 강우의 저장과 저장량을 초과한 강우에 대한 유역 전반의 침투를 통해 물관리를 계획하였다. 연구결과, 계획한 수변도시의 물순환 목표는 전체 강우의 52 %, 백분위수 비교를 통한 80 percentile의 강우 17 mm/day를 처리할 수 있는 것으로 확인되었다. 이러한 산정절차결과에 정량적으로 질을 높이기 위해서 추후에 저영향개발 요소의 안전성이나 적정제원선정 등과 같은 여러 변수들을 고려한다면 물순환 목표 산정에 신뢰도가 더 높을 것으로 사료된다.

  • 도시화와 산업화로 인하여 불투수면적이 증가함에 따라 강우유출에 의한 비점오염원이 수계에 미치는 영향이 커지고 있다. 과거에는 비점오염원을 관리하기위해 장치형 시설(BMP)이 많이 사용되었으나 최근 LID(Low Impact Development)기술을 통해 자연적으로 처리하는 기술이 많이 활용되고 있다. 본 연구에서는 자연형 시설 중 식생체류지에서의 강우 모니터링을 실시한 데이터를 토대로 SWMM 모델을 통해 다양한 강우사상을 모의하였다. LID 모델링 연구의 특징으로 실데이터가 자연시설을 통해 얻은 결과이기 때문에 단기간 데이터로는 정확한 모델링 자료를 구축하기 어려워 정확한 모델을 구현하기가 힘들다는 특징이 있는데, 본 연구에서는 3년간 모니터링한 데이터를 통해 정밀한 모델을 구축하였다는 점에서 의의가 있다. 총 18회 모니터링한 실데이터를 모의하였으며, 유입량과 유출량, 오염물질 5개항목의 제거효율을 모의하였다. 성능평가를 실시한 결과 7개 항목 대부분이 우수한 지표를 나타내었으며, 상대적으로 TN과 TP 항목이 모의성능이 낮은 것으로 나타났다. 미래에는 우리나라도 상수도 시스템과 하수도 시스템이 실질적으로 통합되어 운영되는 통합물관리 시스템이 도입될 것으로 예상된다. 따라서, 본 연구결과는 미래형 통합물관리시스템에서 강우를 초기에 관리하는 단계에서 중요한 역할을 할 수 있을 것으로 판단되며, 설치예상지역의 강우유출저감 및 오염물질 저감 정도를 사전에 예측할 수 있으며, 이를 통해 식생체류지의 과다설계를 방지할 수 있을 것으로 기대된다.

  • It is thought that the sanitary perception and hygienic food treatment of food suppliers as the first handlers of foodstuffs are extremely significant for the safe and sanitary management of food in group meal services. So in this study, a survey of 103 food suppliers who provide raw materials for 80 meal services in business places around Busan area was conducted on general matters, participation in sanitation education, sanitary perception, sanitary treatment of foodstuffs, knowledge of sanitation, etc. The results of the survey are as follows: 1. 42.7% of the subjects have worked for the food supply companies for one to five years and the main job of 36.9% of them is delivery service. Food suppliers who handle over two foodstuffs are 6839%. 2. Concerning the participation in sanitation education, 43.7% of the subjects have not experienced any such education, The reason of 23.3% of them for not having the education is that there have been no opportunity for them at all. And 83.5% of them regard the education on hygiene as necessary. 3. In the sanitary perception, 93.1% of the subjects considered the temperature control of the food delivery vehicles as important and 82.5% of them replied on of the leading causes of food poisoning as foodstuffs. 64.0% thought of their knowledge of food sanitation as not very good, but moderate. 4. Concerning sanitary treatment of foodstuffs, 50.5% of delivery vehicles were wearing sanitary uniforms and 24.3% of them washed their hands while supplying food. 5. In the score of hygienic knowledge, the average score of all food suppliers was 60.6 point. In the score of hygienic knowledge on general matters, managing supervisors got 6.31$\pm$1.70. In the score of hygienic knowledge based on the perception of food sanitation, the food suppliers with the experience of sanitation education scored 6.42$\pm$1.93 point and the point was significant(p<0.01), compared with that of the food suppliers without the experience of sanitation education. The food suppliers who answered their knowledge was very good scored the highest point, 8.00$\pm$1.41. The food suppliers who replied that sanitation education was truly necessary recorded the hygienic knowledge score of 6.75$\pm$1.77, significantly(p<0.01) high. In the score of hygienic knowledge on the basis of the practical degree of sanitary handling of food materials, the food suppliers who answered they cleaned their delivery vehicles everyday scored 6.48$\pm$1.93, the food suppliers who answered they sterilized their delivery vehicles everyday scored 6.29$\pm$1.89, the food suppliers who answered they controlled the temperature of their delivery vehicles irregularly scored 6.58$\pm$1.79 and the food suppliers who answered they washed their hands every time when they were working scored 6.86$\pm$2.24, significantly(p<0.05) high in comparison with every item in other factors. And the food suppliers who answered they were wearing sanitary uniforms irregularly while supplying foodstuffs scored the highest point, 6.66$\pm$2.92.

  • I have observed the validity of open-offer from a point of European contract law in comparison with International Trade Law in this paper. Generally we know that an offer is an expression of willingness bo be bound to the contract. In English law if there are no intention it will be considered such as circulation of price lists or catalogues. As for French law these activities could be considered as an offer. However German law is closer to English law as to an offer. A contract which does not ascertained price is open-price terms and it can be applied not only for general commercial contracts but also for franchise or for distributorship agreements especially in Europe. When open-price terms applied to reserve a exclusive right to the contract the validity of contract can be a serious matter between principals. In English law an offer must be sufficiently complete to be capable of acceptaqnce. English law does not require that price terms should be indicated on offer. English law allow a open-price terms in the contract. In French law a contract will be valid in the absense of a price which is either determined or objectively determinable. A price by the market price of similar products is not enough to be valid offer. It should be recognized and accepted objectively by third parties. French law require that price terms should be indicated on offer. Open-price terms are not enough to be an effective offer. However German law shows more flexible than French law. In German law if the price is not fixed in the contract there are four ways to determine it. The seller may determine the price by the time of deliver. By reason of thess backgrounds I have made comparison with European contract law and International trade law on the validity of open-price offer in this paper. It seems that we are not familiar with open-price terms although franchise contract or special terms of contract have been increased in these days. So I hope this paper will be helpful to show a new point of view.

  • This paper reviewed the concept of the energy flow in east and west. The differences in the views of the energy flow between oriental and western thought were compaired according to the ontological point of view. Human body take up energy and material on open system which maintains homeostasis. Human and environment are continuously interacting in a state of co-existence. Human has energy field called "aura" and seven chakra in energy outflow moving came as meridian. Qi is an invisible cosmic energy helping the fundamental human activity and changes. The basic action of Qi is helping the human growth and development, maintain the body temperature and preventing the intrusion of microorganism. In the normal healthy organism, all are maintained in balance and in a continuous circulation of Qi, while illness is the result of the disturbed Qi flow in the aspect of Qi-theory. Although there are differences between oriental and western medicine in approaches to clients, the basic point of view and philosophy have many similarities on fundamental level. An understanding of the basic thought of energy flow and oriental concept of energy flow implies a more comprehensive meaning than the perspective of unitary transformation discussed in modern western thought of energy flow. Now we should avoid narrow view of energy concept and regard energy flow as an integrated concept with Korean culture. Regarding Qi-theory which provides a comprehensive and humanistic and ethical foundation for nursing philisophy through this overview, it is hoped that a contribution will be made to the development of nursing intervention which is suitable to Korean context.

  • Background The trapezius muscle flap is not usually the first reconstructive option for skin and soft tissue defects in the posterior neck and scalp due to surgeons' unfamiliarity with the surgical anatomy and developments in free tissue transfer techniques. The goals of this study were to describe the clinical use of trapezius flaps in posterior neck and scalp reconstruction, and to investigate the vascular anatomy of trapezius flaps in Asians in order to obtain information facilitating the safe design and elevation of flaps in which most of the muscle is preserved. Methods A retrospective chart review was performed of 10 patients who underwent trapezius muscle flap for posterior neck and scalp defects. We also performed an anatomical study of 16 flaps harvested from 8 preserved Asian adult cadavers and evaluated the main landmarks relevant for trapezius muscle flap. Results In the anatomical study, the mean vertical height from the inferior angle of the scapula to the point at which the superficial cervical artery penetrated the trapezius was $4.31{\pm}2.14cm$. The mean vertical height of the trapezius muscle flap pivot point was $9.53{\pm}2.08cm$ from the external occipital protuberance. Among the 10 flaps, partial necrosis on the overlaid skin graft occurred in 1 patient and postoperative seroma occurred in another patient. Conclusions Vascular variations in the trapezius muscle flap are uncommon in Asians, but when present, such variations appear to have little impact on harvesting the flap or on its circulation. The trapezius muscle flap is a viable alternative for posterior neck and scalp reconstruction.

  • The design process of ecological and environmental detention system located in the housing district of Sinjeong 3-jigu in Seoul are as follows. At stage one, a new dispersal detention was created in the neighborhood park located near the originally planned detention. From this, the amount of storage of this dispersal detention system was enlarged from $28,337m^3/d$, the initial storage amount, to $33,606m^3/d$ as the post storage amount, responsible to the amount of rainfall which happens every 100 years. In particular, the SSB (Sustainable Structured wetland Biotop) system, which was the New Excellent Technology verified by the Ministry of Environment (No. 258) was applied to enhance ecological functioning and water quality with the detention as a constructed wetland. At stage two, the treatment plans for non-point pollutant source occurred at the initial period of rain, flowing into the detention system were built for purifying the water of the retention pond at the base of the detentions, and the water-circulation system was designed at the dispersal detentions on the period of regular rainfalls. The non-point pollutant source flowing into detention site was calculated as $11,699m^3/d$ flowing down from seven small watersheds, which occurred at the initial period of rain. In particular the SSB systems improved the average efficiency of the water processing performance to BOD 60%, SS 90%, T-N 30%, T-P 60%. At stage three, the ecological network and biological diversity were strongly considered so that it brought the residents with amenity places. In particular, the dispersal detentions were successfully designed to restore the ecological habitat of endangered plant and animal species such as narrow-mouthed.

  • 각종 개발사업은 불투수층의 증가를 야기 시켜 자연적 물 순환 왜곡과 함께 비점오염물질의 유출을 증가시킨다. 개발로 인한 환경생태수리학적 영향을 저감하고 건전한 물 순환을 구축하기 위해서는 오염물질의 함량이 적은 유출유량에 대해서는 이용(use)을 고려해 볼 만하며, 오염물질의 함량이 높은 유량에 대해서는 조경공간에서 처리 후 저류, 침투 또는 증발산을 고려하여야 한다. 본 연구는 지붕빗물유출수의 상대적 오염도를 평가하여 이용가능성을 검토하고, 평균 EMC 산정을 위한 비용 효율적 적정 모니터링 기법을 제안하고자 수행되었다. 지붕유출수의 오염도는 도로와 주차장에 비해 오염물질별 3배에서 13배 정도 낮은 것으로 조사되었으며, 나뭇잎, 담배꽁초 등의 협잡물과 바람의 영향으로 인한 오염물질의 대기침적 및 옥상구조물 등이 주요 오염원인 것으로 나타났다. 비용 효율적 모니터링 기법 연구결과 평균 EMC를 보이는 시료는 유출 발생 후 약 15분 경인 것으로 나타났으며, 최소 8회 이상의 강우사상에 대한 모니터링이 수행되어야 평균 EMC를 산정할 수 있는 것으로 나타났다.
