노인요양시설은 다양한 욕구와 문제를 가진 노인들이 생활하는 공간으로서 개별화된 전문적인 요양서비스를 제공해야 한다. 한편 공급자 중심의 케어에서 거주자 중심으로의 케어 환경의 변화에 따라 유니트 케어 시스템의 도입 필요성이 제기되고 있으나 관련 연구는 거의 전무하다. 유니트 케어의 도입은 단순한 생활공간의 물리적인 변화뿐만 아니라 조직 전반의 변화가 수반되어야 한다. 이에 본 연구는 유니트 케어의 도입을 실제로 도입한 장기요양시설을 대상으로 조직변화 모형을 적용하여 유니트 케어의 도입과정을 분석하였다. 분석 결과, 유니트 케어의 도입에 있어 시설장의 리더십, 조직학습 분위기의 조성, 조직구성원에 대한 보상체계의 확립 등의 요인이 중요하다는 점을 확인하였다. The nursing homes as a living space of the elderly who have various needs and problem should provide the personalized and professional care service. Meanwhile, with the changing of care environment from Facility-centered care to Resident-centered care in nursing home, the introduction of unit-care systems is emphasized. But, there is little research on the unit care system. In terms of organization theory, the introduction of unit care is related to the overall organization change as well as living space change. So this study have analyzed the application case of unit care system through the organization change model focusing on K nursing home. As a result of analysis, this study shows that following factors are important in nursing home: the building of a learning organization, leadership of top leader, a reward systems to motivate.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

This paper studied the possibility to predict a mechanical property variation from changes in created carbonyl bands by irradiating the surface of high-density polyethylene with short-wavelength ultraviolet radiation of 254nm to induce a fast chemical degradation. The meaning of this study lies in checking whether a mechanical property change with the same chemical property as the induced optical deterioration is caused by using a UVC lamp with high photon energy instead of optical deterioration via xenon arc light source and outdoor exposure test via natural sunlight requiring a long time. The mechanical strength of high-density polyethylene checked by a tensile test and a creep destruction test showed a similar tendency with CI changes. In particular, the yield strength and elongation had a close relationship with the exposure time to ultraviolet radiation. Accordingly, this paper presented a method to grasp the mechanical property change outdoors requiring a long time more fast through the relationship between the mechanical property change and the carbonyl index using a UVC lamp causing the fast surface degradation.

유사란 하천수에 의하여 운반되는 토사를 말하며 유수에 의해 침식, 퇴적이 반복되는 결과를 낳는다. 최근 기후변화와 함께 대규모 홍수가 빈번해 짐에 따라 하천의 유사량이 커지고 4대강 사업처럼 대규모 하천사업으로 인한 하상변동이 심해지고 있다. 하천에서 총유사량 추정은 하상변동의 원인이 되기도 하고 수자원 개발 및 관리를 위한 하천계획에 필요한 기본적 요소이다. 하지만 국내에서는 대규모 하천에서의 유사량은 측정을 실시하고 있지만 중소하천의 경우 유사량을 실측하여 산정할 수 있는 시간적 경제적 부담 때문에 측정할 수 있는 한계가 있다. 본 연구에서는 경기북부에 위치한 차탄천, 포천천, 경기남부에 위치한 남양천의 각 유량에 따른 부유사를 채취하여 시료분석을 통한 결과와 이론식을 적용하여 비교 분석 하였다. 채취한 시료는 입도분석을 실시하였으며 현장 측정 자료와 실내실험 결과를 토대로 수정 아인슈타인공식을 적용한 BORAMEP 프로그램을 사용하여 총유사량을 산정하였다. 분석 결과, 3m³/sec 이하 유량에서는 Yang 공식이 실측자료와 일치성을 나타냈고 3m³/sec 이상에서는 Shen and Hung 공식이 잘 나타났다. 각 이론을 적용하여 총유사량을 추정하고, 실측치를 이용하여 비교·검토함으로써 국내 중소하천에 적합한 산정 방법과 경기북부 지역 중소하천의 유량-총유사량 관계식을 제시하였다. Sediment transport means that the materials of bed and suspended load in the river are transported by flow tractive force, which causes scour and deposition. As the climate changes and dramatic flood occurs frequently, the sediment transport has increased and river bed changed. Sediment transport estimation is essential for the water resources management as well as river bed morphology. However, it is difficult to measure the total sediment in the middle and small river due to time and economic constrain. In this study, field data which were observed in 3 different river in Kyunggi-do were analyzed for comparing with empirical equations. Particle distribution analysis were carried out for the collected the suspended loads. The simulation model BORAMEP(Bureau of Reclamation Automated Modified Einstein Procedure) were used for the total sediment estimation along the field data analysis. As a result, Yang`s equation corresponds to field data under 3m³/sec and the equation of Shen and Hung corresponds to results over 3m³/sec. The results showed the way how sediment were estimated and discharge-total sediment relationship was determined by regression analysis in small and middle river of Kyunggi province region.

Korean fir(Abies koreana E.H.Wilson 1920), endemic tree species of Korean peninsula, is considered as vulnerable and endangered species to recent rapid environmental changes such as land use and climate change. There are limited activities and efforts to find natural habitats of Korean fir for conservation of the species and habitats. In this study, by applying SDMs (Species Distribution Models) based on climate and topographic factors of Korean fir, we developed Korean fir’s predicted distribution model and explored novel natural habitats. In Mt. Shinbulsan, Youngnam region and Mt. Songnisan, we could find korean fir’s two novel habitat and the former was the warmest(13°C in annual mean temperature), the driest(1,200mm∼1,600mm in annual rainfall) and relatively low altitude environment among Korean fir’s habitats in Korea. The result of SDMs did not include mountain areas of Gangwon-do as habitats of A. nephrolepis, because there were different contributions of key habitat environment factors, summer rainfall, winter mean temperature and winter rainfall, between A. koreana and A. nephrolepis. Our results raise modification of other distribution models on Korean fir. Novel habitat of Korean fir in Mt. Shinbulsan revealed similar habitat affinity of the species, ridgy and rocky site, with other habitats in Korea. Our results also suggest potential areas for creation of Korea fir’s alternative habitats through species reintroduction in landscape and ecosystem level.

울형성 심부전증에서 심혈관계 보상기전의 지표로서 저나트륨혈증의 의의에 관한 연구

In patient with congestive heart failure, it is well known that the sympatho-adrenal system and the renin angiotensin system are activated to compensate for the reduction of cardiac output and the redistribution of blood flow. Although Lilly, et al. (1984) and Francis, et al. (1985) have insisted that the induction of these circulatory compensation mechanism by pastura1 changes is closely related to the concentration of plama sodium in congestive heart failure, it is still controversial. Thus, in an effort to clarify this hypothesis, present study was designed to determine the relationship between the existing sodium concentration in plasma and the changes of the plasma catecholamine concentration and renin activity during postural alterations in patients with congestive heart fai1ure and normal subjects. Ten patients with congestive heart failure who had been admitted to the Ewha Womans University Hospital from May, 1985 to July, 1985 and five normal volunteers were chosen. Patients with more than one year history of congestive heart failure belonging to class 3 or 4 as the criteria set by the New York Heart Association have been selected for this study. Among these ten patients, 5(3 males and 2 females) had low plasma sodium concentration(below 135mEq/l) and 5(3 males and 2 females) had normal plasma sodium concentration(above 135mEq/l). The observed results are as follows: 1) In the normal subjects, the observed plasma renin activity was 1,2±0.4ng/ml/hr and the concentrations of norepinephrine and epinephrine were 177.5±27 and 150.0±8pg/ml, respectively, at supine position. However, these values were increased by about 2 times by changing to upright position. 2) In patients with hyponatremic congestive heart failure, the values of plasma renin activity and catecholamine levels were significantly higher than those patients having normonatremia. 3) The increase in the plasma renin activity and catecholamin levels induced by upright position were minimal in patients with congestive heart failure having normonatremia. 4) However, in patients with hyponatremic congestive heart failure, the plasma renin activity and the levels of plasma catecholamines were not altered, or rather decreased, by the same postural changes. Based on the results, the levels of plasma sodium concentration in patients with congestive heart failure could provide an index for the induction of circulatory compensation mechaniams and may have important significance in determining the severity and prognosis of the disease. Particularly in the congestive heart failure patients with hyponatremia, as the circulatory compensation mechanism appear to be operating at maximum already, they would not be able to utilize the reflex compensation mechanism inducible with the changes of body position.

The purpose of this article is analyzing the economic impacts of abnormal climate on fall chinese cabbage farmers and consumers in Korea, with employing the equilibrium displacement model. Our results show that there were little difference in gross farm income, even though there were significant yield reductions due to abnormal climate changes. However periodic occurrences of abnormal climates caused serious damage to consumption levels which had declined by 10.6~17.1 percent with higher prices by 15.3~24.6 percent than normal climate years since 1990.

마이크로-플레이트릿 광간섭 안료를 이용한 태양광용 고투과 컬러 유리에 대한 연구

신동윤(Dong-Youn Shin),이진섭(Jin-Seob Lee),신창수(Chang-Soo Shin),성창환(Chang-Hwan Seong) 대한기계학회 2020 大韓機械學會論文集B Vol.44 No.7

인위적인 기후 변화를 유발하는 이산화탄소 배출량을 줄이기 위해 제로에너지 건축이 법제화 되었으나, 종래의 건물 일체형 태양광 모듈은 태양광 발전 효율을 최대화하기 위해 흑색으로만 제작되었기에 심미성을 중요시하는 건축물의 외관에 적용하는데 장애물이 되어왔다. 본 연구에서는 마이크로-플레이트릿 광간섭 안료를 이용한 태양광용 고투과 컬러 유리의 제작에 대해 소개하도록 한다. 광간섭 안료의 함량이 광학 투과율에 미치는 영향을 조사함으로써 색상을 구현하는데 요구되는 광간섭 안료의 최소 함량을 결정하였다. 3wt% 광간섭 안료 함량의 컬러 유리로 태양광 모듈을 제조하고 전기적 특성을 측정하였다. 마이크로-플레이트릿 광간섭 안료의 사용은 진공 증착 다층 박막 적층법으로 색상을 구현하는 방식보다 저렴한 인쇄 공정을 적용할 수 있기 때문에 제조 비용을 절감할 수 있으며, 발전 효율도 기존 태양광 모듈의 76.15%에 이르렀다. The construction of zero-energy buildings will become mandatory to curtail the amount of CO₂ emissions, which lead to anthropogenic climate changes. However, conventional building-integrated photovoltaics are monotonously black in color to ensure high photoconversion efficiency. Hence, this has been a hurdle in aesthetically decorating the skin of a building. In this study, a micro-platelet light-interference pigment is explored for the fabrication of a highly transparent color glass for photovoltaic applications. The impact of pigment concentration on optical transmittance is investigated and the minimum pigment concentration for realizing a vivid color is determined. A photovoltaic module is fabricated using a color glass with a pigment concentration of 3 wt%, and its electrical properties are measured. The use of a micro-platelet light-interference pigment lowers the fabrication cost (by using a printing process) when compared to that of a costly color glass with multi-layered thin films deposited in vacuum. Furthermore, the relative photoconversion efficiency of the proposed method when compared to a conventional photovoltaic module is as high as 76.15 %.

Evaluation of a Dual-Cooled Annular Fuel Heat Split and Temperature Distribution

YANG, Yong Sik,SHIN, Chang Hwan,CHUN, Tae Hyun,SONG, Kun Woo Atomic Energy Society of Japan 2009 Journal of nuclear science and technology Vol.46 No.8

<P>The heat flux and fuel temperature of an annular fuel rod was analyzed using a newly developed program, DUO_THERM. The dual-cooled annular fuel rod has both inner and outer coolant channels. The heat fluxes to inner and outer claddings can change during irradiation because of the variation in the gap conductances of the inner and outer sides. The heat flux is a very important design factor affecting fuel integrity and safety. However, in an annular fuel design, the prediction of heat flux is very complicated because it is closely connected with size changes of two gaps, which are different from each other during irradiation. A burnup increase and power change can cause pellet and cladding radial deformation and eventually change the gap width. Because an annular fuel has two gaps at both sides and their heat resistances are very large, an imbalance of the gap width can lead to heat flux asymmetry. Therefore, a pellet and cladding dimensional change including densification, swelling, creep, and thermal expansion must be considered in the calculation of heat flux and temperature. By using the DUO_THERM program, the changes in heat flux and temperature during an operation were evaluated with respect to a reference design of an annular fuel. The results of the evaluation showed that the heat flux of an annular fuel was greatly affected by the inner and outer gap conductance changes. The heat flux of the inner cladding was maximum at zero burnup, but that of the outer cladding was maximum at the burnup of the outer gap closing. In addition, the maximum fuel temperature location was changed by gap conductance asymmetry.</P>

Computed tomography is of prime importance in the diagnosis of epilepsy. In a previous study, one of the authors (Chang) reported that the proportion of organic lesion in epilepsy was approximately 49% according to CT examination. In this article, the authors studied the correlation of EEG and CT findings in 232 epileptic patients, who had been managed in Kyung-Hee University Hospital from October 1977 to March 1981. The patient population consisted of 155 males(66.8%) and 77 females(33.2%). Age distribution was broad ranging from 3 months to 72 years and 75% of patients were below the age of 40. The types of epilepsy were centrencephalic epilepsy(145 grand mal and 2 petit mal); 64.5%(N=147) and focal epilepsy(6 Jacksonian, 12 T.L.E, and 67 others); 36.5%(N=85). Data were analysed and the following results were obtained: 1. There were no statistically significant differences in abnormal findings by using EEG(N=153, 65.9%) and CT(N=144, 62.1%) in total epileptic patients. 2. Abnormal CT findings in focal epilepsy(75.3%) was more frequent than that of centrencephalic epilepsy(54.4%). 3. According to the rough subdivision of lesion sites (left, right, or diffuse), concordance rate of sites of abnormal EEG and CT was significantly high (74.7%, p<0.01). 4. Focal slowings in EEG was associated with higher proportion of abnormal CT (81.2%), as compared with focal paroxysms(29.4%).
