Purpose: Clinical laboratory of hospital has been demanded to extension or relocation regarding with the test number increase and analyzer development. Space area criteria per test numbers, lab functions, hospital bed and lab staffs are needed for draft space programing. So, the purpose of this study is to provide the space area guideline of clinical laboratory for space calculation in planning and design the spatial environment. Methods: Literature review has been used in checking the standards and guidelines. And questionnaire surveys to laboratory supervisors in hospitals have been conducted for the data collection. 60 answers have been analysed statistically by MS Excel program. Results: The result of this study can be summarized into three way calculations. The first one shows that the basic standard workspace and distance is applied in lab design. The second one shows that average space area criteria resulted from case studies is applied by 19㎡ per one staff, 0.9~1.0㎡ per one bed, and lastly linear length calculation of workbenches and analyzers on the bench top and floor mount, is multiplying it by the sum of the counter depth plus aisle width. Implications: In updating the space area calculation guidelines, it is necessary to cooperate with medical staffs and designers.

The rehabilitation for the workplace accident victims is basically aimed to get them back to their working place through the secondary care processes which have some more special and more professional rehabilitation than any others, after the primary treatments like operation in an acute hospital since the accident. They need more concentrative rehabilitation efforts according to classified injury types during the period of acute, sub-acute and convalescent. This study is for the partial research of rehabilitation hospital for workers' accident victims and presents design data which can be used for the appropriate area calculation and spatial composition. Drawing documents analysis, interviews, observation were used to examine the condition of existing rehabilitation hospitals.

Kerma Area Product (KAP) is best indicator of radiation monitoring on radiographic examinations. KAP can be measured differently depending on the X-ray irradiation area, air kerma, souce-skin distance, type of equipment, etc. The major factors are exposure area and the air krema. The KAP currently used only considers the exposure area with X-rays and has a problem that KAP is always excessively overestimated from the dose received by an actual subject. Therefore, in this study, in order to measure the accurate KAP, a new area dose calculation that can be calculated by dividing the area where the actual X-ray is irradiated is presented, and the KAP is the real area. We compared and analyzed how much it was overestimated compared to the dose. The Skull AP projection and seven other projection were compared and analyzed, and the KAP was overestimated in each test by 52% to 60%. In this way, the effective KAP (EKAP) calculation developed through this study should be utilized to prevent extra calculation of the existing KAP, and only the accurate patient subject area should be calculated to derive the accurate area dose value. EKAP is helpful for control the patient's exposure dose more finely, and it is useful for the quality control of medical radiation exposure.

Nowadays, a concern of building environment has been arousing. Furthermore, according to this trend, the social concern has expended continuously. Especially, the right of daylight is essential for both the pleasant life and building maintenance. In this reason, it has dealt as like property right. Therefore, the Infringement on the right of daylight can be applicable to the infringement of property right. However, few un-notarized calculation methods have been used without careful examination about daylight duration calculation methods which can be used for determine sunshine infringement as the dispute solution, therefore. In this thesis We analyzed and concluded the differentiations of two calculation methods which are using nowadays.

Samchunpo(Sin Hyang) Harbor is located in the bay of Sa Chun, the central south coast of Korean peninsula. The harbor and coastal boundaries have been protecting by natural coastal islands and shoals. Currently, The Sin Hyang harbor needs maintenance and renovation of the sheltered structures against the weather deterioration and typhoon damages. Consequently to support this, the calculation of accurate design wave through the typhoon wave attack is necessary. In this study, calculation of incident wave condition is simulated using steady state spectrum energy wave model(wide area wave model) from 50 years return wave condition. And this simulation results in wide offshore area were used for the input of the extended mild slope wave model at the narrow coastal area. Finally, the calculation of design wave at Sin Hyang harbor entrance was induced by Boussinesq wave model(detail area wave model) simulation. The numerical model system was able to simulate wave transformations from generation scale to shoreline or harbor impact. We hope these results will be helpful to the engineers doing placement, design, orientation, and evaluation of a wide range of potential solutions in this area.

We have limited the transfer power to capital area below a certain level which is called "The Capital Area Transfer Power Limit", and calculated on every Thursday for the application next week. This level is very important in our network operation, because if this level is not set properly, our power network can be fallen under great danger in case of a fault among the transfer power line. But the calculation procedure for the limit level is so complicated and iterative that it mace us spend much time and do much work. So, when a sudden trip of the related facility to the limit level we can't recalculate the limit level fast enough. And this can drop our network reliability below our standards, therefore our network can be dangerous. To avoid this kind of problems, we have figured out a method to calculate simply the limit level. That method uses the index related to the level. We think this method can make short of the calculation procedures for the level. This paper deals with the simplified method for the calculation of the level limit.

This study has intended to evaluate the subjective landscape of rural region using additive integration index calculation model in Seondong region, Gochang-gun, Jeollabuk-do, Korea. This study consists of the following three steps. First, this study defmed the rural landscape using survey and developed the estimating equation for rural landscape assessment index. Second, this study set up assessment units and assessment indicators, then estimated mean of representative landscape adjectives in accordance with them through residents-participatory evaluation. Third, this study calculated rural landscape assessment index using additive integration index calculation model, and evaluated subjective landscape of rural region in accordance with space types and landscape fields through mapping methodology. The results of this study can be described as follows: 1) satisfaction level for landscape in accordance with village (urban area and residential area) was very high; 2) satisfaction level was very high in both Ye-Jeon reservoir and Hakwon farm, representative landscape resources of the study area.

This paper presents a method to calculate the area of vulnerability by using the impedance building algorithm. The installation of DG (Distributed Generation) is one of the countermeasures against voltage sags in power systems. In order to estimate the effect of the DG, the voltage sag assessment should be performed based on the area of vulnerability and system fault statistics. To determine the area of vulnerability, system impedance matrix should be calculated. The calculation of the impedance matrix of large systems is time-consuming task. This paper addresses an effective scheme to calculate the area of vulnerability and system impedance matrix.

본 연구의 목적은 핵의학검사를 하는 수검자(환자)의 유효선량(mSv)을 손쉽게 산출할 수 있는 전용 프로그램을 제작 보급하여 핵의학검사의 피폭선량 연구와 선량정보 공개를 위해 조력하고자 한다. 프로그램은 ICRP 80, 106 Report와 추록4에 수록되어 있는 방사성의약품의 방사능당 유효선량(mSv/MBq)을 Database로 만든 다음 5가지(Area, Clark, Solomon(Fried), Webster, Young) 소아주입량 산출법과 7가지 체표면적 산출법이 적용되도록 Microsoft의 Visual Basic(In Excel)으로 제작하였다. 프로그램은 수검자의 연령, 방사성핵종, 표지화합물, 그리고 인체주입량을 입력하면 유효선량(mSv)이 산출된다. 소아의 경우 연령 입력 시 소아산출법이 활성화 되며 적용할 소아산출법을 선택하면 된다. 그리고 소아산출법 중 Area법을 선택하는 경우 체표면적산출법을 고르는 선택창이 활성화 된다. 그런 다음 성인의 주입량을 입력하면 소아의 주입량과 유효선량(mSv)이 자동으로 산출된다. 본 연구에서 제작한 핵의학검사의 환자 유효선량 계산 프로그램은 실제 계측선량이 아니지만 핵의학 검사 시 받게 되는 인체의 내부피폭선량을 가장 근접하게 산출할 수 있는 도구로서 의미가 있다. 향후 프로그램의 활용도를 높이기 위해 모바일기기에서 사용할 수 있는 애플리케이션으로 제작하여 일반인도 쉽게 접근할 수 있도록 할 것이다.
