본 연구는 약 20년 동안 어린이놀이터 관련법규의 변화내용을 연도별, 법규별로 분석하여 관련법규의 변화가 놀이터 디자인 변화에 영향을 주었는지 연구하였다. 분석결과, 법규별, 년도별 변천내용에 대한 연구대상지의 디자인 변화는 법규 항목별로 영향을 미치는 시기, 내용이 각각 차이가 있는 것으로 나타났다. 첫째, 도로 및 주차장으로 부터의 이격거리, 놀이시설간 안전휀스의 설치, 내구성 있는 재료의 사용 등이 항목 개정시기 이후 디자인 변화에 영향을 준 것으로 나타나고 있다. 둘째, 법규의 제 개정 이후 디자인의 변화가 나타나는 항목들은 상록수의 차폐, 일조조건이 양호한 위치의 선정 등이다. 셋째, 법규의 변화가 놀이터 디자인 변화에 영향을 미치지 않는 항목은 놀이터 내 주민운동시설의 대체가능, 위생진단 연 2회 이상으로 나타났다. 이렇게 영향요인별로 차이가 발생한 원인은 놀이터 디자인에 정확히 반영할 수 있는 법규의 세부기준이 부족하여 임의 해석을 통하여 영향을 주거나, 시간이 지나면서 외부공간의 질적 향상의 변화추세에 맞추어 반영되어진 것으로 판단된다. 또한, 주민운동시설로의 대체는 완화규정이라 할 수 있어 연구대상지 여건에 따라 주관적인 반영이 있는 것으로 판단되어진다. 이러한 법규의 변화내용이 놀이터 디자인 변화에 정확히 반영이 되어지기 위한 법규의 개선방안을 제시하였다. 특히, 법규의 준수가 가능한 구체적 기준의 제정이 필요한 것으로 나타났다. 예를 들어 상록수의 차폐는 놀이터 주변 녹지의 폭, 차폐 권장수종, 차폐의 길이 등의 보완이 필요하며, 일조조건이 양호한 위치는 놀이터의 향을 제한하거나, 인접 건축물과의 이격거리 기준 등을 제시하는 것이 필요한 것으로 판단된다. 그리고 최근 설계지침과 과업내용에서 나타나며 서론에서 언급한 놀이의 기능을 충실히 하기 위한 다양한 외관, 변화가 가능한 형태, 테마공간의 부여 등 "어린이 놀이터 설계기준(가칭)"이 마련되어 법규의 부족한 부분을 보완하는 것이 필요할 것으로 판단된다.

In order to apply a static fault-tree (FT) method to a system or a plant whose configuration changes dynamically, condition gates and a post processing method are used to effectively accommodate these changes. An operator's performance change, which can be caused by these configuration changes, should also be considered to assess the risk to a plant in a more realistic manner. This study aims to develop an integrated framework to accommodate various configuration changes and their effect on an operator’s performance by using the FT model. We applied a condition-based human reliability assessment (CBHRA) method to consider various conditions endured by an operator. That is, we integrated the CBHRA method with the conventional post processing method for modeling the system configuration changes. The effect of the condition monitoring systems installed in a plant is also considered. In this study, we show an example application of the integrated framework to a probabilistic safety assessment for the shutdown phase of a nuclear power plant.

In our previous work using a motion analyzer and 3-dimensional sonic digitizer, the arm shapes for 23 women in their early twenties were classified into three characteristic types. In order to design sleeves, suitable for arm movements for the three characteristic arm shapes, a relationship between arm length variation and shoulder/elbow angles has been investigated for four cases of arm movements (flexion, extension, adduction and abduction). Each arm movement can be characterized by the changes in shoulder angle and the changes in elbow angle at the maximal shoulder angle. In all the four cases of arm movements, the changes of shoulder length and cap height are largest at the maximal shoulder angle. These changes were little affected by changes in elbow angle. The changes in the lower arm length and the difference between cap height and upper arm length are the largest at the maximal elbow angle of the maximal shoulder angle. There is a linear relationship between cap height and shoulder angle during arm movements; thus, in designing sleeves the cap height can be determined from the regression of cap height vs. shoulder angle.

In the thermal power plant, it is difficult to maintain strict control of the steam temperature in order to avoid thermal stress, because of variation of the heating value according to the fuel source, the time delay of changes in main steam temperature versus changes in fuel flow rate, difficulty of control on the main steam temperature control and the reheater steam temperature control system owing to the dynamic response characteristics of changes in steam temperature and the reheater steam temperature, fluctuation of inner fluid water and steam flow rates widely during load-following operation. Up to the present time, the PID controller has been used to operate this system...

In this study, statistical analysis under both stationary and non-stationary climate was conducted for rainfall data measured in Seoul. Generalised Extreme Value (GEV) distribution and Gumbel distribution were used for the analysis. Rainfall changes under the non-stationary climate were estimated by applying time variable (t) to location parameter (${\xi}$). Rainfall depths calculated in non-stationary climate increased by 1.1 to 6.2mm and 1.0 to 4.6mm for the GEV distribution and gumbel distribution respectively from those stationary forms. Changes in annual maximum rainfall were estimated with rate of change in the location parameter (${\xi}1{\cdot}t$), and temporal changes of return period were predicted. This was also available for re-evaluating the current sewer design return period. Design criteria of sewer system was newly suggested considering life expectance of the system as well as temporal changes in the return period.

This study was done with a goal to observe changes of color emotions according to time flow and light changes as well as to study its moaning of color experience of natural scene to modern city dwellers with artificial surroundings. Individuals develop various feelings after seeing a color, but there is sometimes a common feeling raised among these various feelings. This study aims to investigate the influence of natural colors of surroundings on the emotions of human beings. First of all, we tried to discover how feelings change after a person is reminded of a color through an experience (recognition) of a natural color. Second, differences in feelings resulting from color perception are analyzed after time passes (sunrise, daytime, and sunset) and the colors of natural surroundings change accordingly. Survey was done in the period of $Jul.8^{th}$ to $10^{th}$, 2005 with 100 people (55 male and 45 female) in various professions and various ages between twenties to forties as respondent.

For stable and sustainable crop production, understanding the effects of climate changes on agricultural water resources is necessary to minimize the negative effects which might occur due to shifting weather conditions. Although various studies have been carried out in Korea concerning changes in evapotranspiration and irrigation water requirement, the findings are still difficult to utilize fordesigning the demand and unit duty of water, which are the design criteria of irrigation systems. In this study, the impact analysis of climate changes on the paddy water demand and unit duty of water was analyzed based on the high resolution climate change scenarios (specifically under the A1B scenario) provided by the Korea Meteorological Administration. The result of the study indicated that average changes in the paddy water demand in eight irrigation districts were estimated as -2.4 % (2025s), -0.2 % (2055s), and 3.2 % (2085s). The unit duty of water was estimated to increase on an average within 2 % during paddy transplanting season and within 5 % during growing season after transplanting. This result could be utilized for irrigation system design, agricultural water resource development, and rice paddy cultivation policy-making in South Korea.

A glove design which reflects the changes in hand surface by hand motion can reduce the undesirable effects of use of gloves on hand performance. The present study examined changes in hand length dimensions due to hand motion and identified significant factors affecting the length changes. Recruiting 120 males and females in their 20s and 30s having various hand lengths, this study measured 10 hand length dimensions, defined at 2 hand areas(phalangeal and metacarpal areas) for 5 digits, when the hand is stretched and in fist, and then calculated the percentage of length increase for each dimension. ANOVA and simple-effect analyses showed the length change percentages were mainly different depending on digit and hand area: 111-127% at the phalangeal area and 112-116% at the metacarpal area. The length change percentages of the index, middle, ring, and little fingers in the phalangeal area ascended in order and showed a high correlation(r = 0.94)with the ranges of motion of the fingers.
