We investigated springs in Seoul in 2009 to know the change of water quality according to storage method of spring water, the concentration of chemical compounds and their correlation. Even spring water that originally satisfied national standard for drinking water could be exceeded national standard for drinking water by storage method such as storage bottle, temperature and period; especially used PET bottles could affect the increase of total colony counts. Therefore, spring water is desirable to be consumed on the spot, or to be stored in sterilized bottles in refrigerator rather than room temperature at home, and also to be consumed shortly not exceeding 24 hours. Total colony counts, coliform, yersinia, $F^-$, $Cl^-$, $NO_3^--N$, hardness, total Solids, pH, color and Al were exceeded national standard for drinking water at some springs. The result of correlation analysis shows that hardness and total solids, which are caused by several ionic compounds, had relatively high correlations with other chemical compounds.

$\beta$ -Lactam Derivatives as Inhibitors for Carboxypeptidase A. Enzyme Inhibitor Design, Part 17

김광래,Kim, Gwang Rae 대한화학회 1996 Bulletin of the Korean Chemical Society Vol.17 No.1

2-(Azetidin-2-one-1-yl)-3-phenylpropionic acid and 2-(azetidin-2-thione-1-yl)-3-phenylpropionic acid were designed as potential active site directed inactivators for carboxypeptidase A, but shown to be they are competitive reversible inhibitors for the enzyme. The observation was somewhat surprising, but is not unexpected considering the recent report of Page who questioned the validity of the generally believed notion that $\beta-lactam$ ring is highly unstable.

The purpose of this study was to suggest objective basic data for landscape research which cotained interdiciplinary approach between ecological and psychophysical method. For this, the naturalness and preference in greenary space, spatial image structure of physical elements have been analyzed by correlation coefficient and factor analysis algorithm. The results are as follows; 1. The relation between the estimation of naturalness and the preference in natural forest was deeply correlated. And the estimation of naturalness was higher than the estimation of DGN(Degree of Green Naturality). 2. The estimation of naturalnesss was decided by the physical features of forest and was different from the DGN. 3. Factors covering the spatial image of the forests have been found to be the 'overall evaluation', 'ability', 'naturalness' and 'idiosyncracy'. By using the control method for the number of factors, T.V. has been obtained as 61.68%. 4. The factors of the 'overall evauation', 'naturalness' were found to be the main factors determining the visual preference of greenary space.

The structural characteristics of the stiffened double cylinder was investigated through experiment and analysis. The outside cylinder was excited with piezoelectric actuator and the mode shape of the cylinder with stiffening T frame was obtained by using holographic interferometry. Finite element method was applied for further modal investigation of the stiffened cylinder. The experimental results showed that the mode shape of cylinder was dependent on the exciting frequencies and the T frame showed salient effect of damping at most of the resonent frequencies. In particular frequencies, the T frame worked as a transmitter. FFM showed similar results with the experiments. This paper showed that the laser-based method such as holographic interferometry is well suited for investigation of the whole-field mode shapes and FEM has good performance to estimate the medal characteristics of the mechanical structure.

We surveyed the citizens opinion about springs in Seoul for two years from 2008 to 2009. It was found that spring water was mostly used by citizens older than 50, and that 29.5% of citizens used purified tap water as drinking water, 27.2% of them used boiled tap water, 21.1% of them used spring water, and 12.1% of them used bottled water. Citizens who store spring water more than a day are 76.7%. Although many citizens (70.3%) knew that water quality had been tested, 40% of them didn't care about checking the certificate of water quality analysis. Once recognized that the spring water was unfit for drinking exceeded standard of drinking water, 85% of citizens would rather not use the spring water.

김광래,조규동,구자용,Kim, Kwang-Rae,Cho, Kyu-Dong,Koo, Ja-Yong 한국통계학회 2010 Communications for statistical applications and me Vol.17 No.6

본 논문에서는 통계적 역문제로서 이항 선택모형에서의 밀도추정 방법에 대하여 연구하였다. 밀도함수의 추정을 위하여 직교열 기저를 이용하였으며, 모형의 복잡성과 예측의 정확성을 반영한 적절한 절단모수의 선택에 대하여 고려하였다. 이항 선택 모형에서 데이터에 의존하는 절단모수를 선택하는 방법에 대해 제안하고 모의실험, 실자료를 통해 제안한 방법의 성능을 규명하였다. This paper deals with a density estimation method in binary choice models that can be regarded as a statistical inverse problem. We use an orthogonal basis to estimate density function and consider the choice of an appropriate truncation parameter to reflect the model complexity and the prediction accuracy. We propose a data-dependent rule to choose the truncation parameter in the context of binary choice models. A numerical simulation is provided to illustrate the performance of the proposed method.

수중과 지상에서의 태극권 운동수행이 노인 여성들의 활동 체력에 미치는 영향

김광래(Kim Kwang Lae),김지혁(Kim Ji Hyeok),김태욱(Kim Tae Wook),Richard B Kreider 한국노년학회 2014 한국노년학 Vol.34 No.4

태극권 운동은 노인 여성들의 활동 체력을 향상시켜 주는 운동으로 알려져 있다. 그러나 수중에서 태극권 운동을 수행하는 것이 효과적인지 아니면 지상에서 수행하는 것이 효과적인지는 제시되지 않고 있다. 따라서 본 연구의 목적은 수중과 지상에서 태극권 운동을 수행한 후 노인 여성들의 활동 체력을 비교ㆍ분석하여 태극권의 효과적인 운동 형태를 제시하고자 하는데 있다. 서울시 소재 N 실버타운에 거주하는 노인 여성들 중 태극권 운동을 수행하는데 있어서 신체적ㆍ정신적으로 문제가 없는 26명의 노인 여성들을 연구대상으로 하여 수중 태극권 운동집단(n=13)과 지상 태극권 운동 집단(n=13)으로 분류하여 손식 태극권을 50-65분, 주당 2회, 32주간을 실시하여 활동 체력을 태극권 운동전, 태극권 운동16주후, 태극권 운동32주후에 측정하여 비교ㆍ분석 하였으며, 활동 체력검사 항목들 중 6분 걷기, 덤벨들기, 의자에서 앉았다 일어나기, 등뒤에서 손잡기, 의자앉아 앞으로 굽히기, 3m 왕복걷기는 senior fitness test(SFT) 방법을 적용하여 검사를 수행하였으며 눈감고 외발서기는 체육과학연구원의 방법을 적용 하여 검사를 수행하였다. 분석 결과 6분 걷기(p<.007), 덤벨들기(p<.043), 의자에서 앉았다가 일어나기(p<.000), 3m 왕복 걷기(p<.003)에서 운동처치 방법과 상관없이 운동기간에서 유의한 차이가 있는 것으로 나타났으며, 등뒤에서 손잡기는 운동기간에 따라 유의한 차이가 있었으며(p<.000), 집단과 기간의 상호작용에서도 유의한 차이가 있는 것으로 나타났다(p<.006). 눈감고 외발서기는 집단간(p<.045), 운동 기간(p<.004)에서 유의한 차이가 있는 것으로 나타났으며, 집단과 기간의 상호작용에서도 유의한 차이가 있는 것으로 나타났다(p<.005). 결론적으로 태극권 운동은 운동 처치 방법에 상관없이 노인 여성들의 심폐지구력, 상지근력, 하지근력, 민첩성(동적 평형성)에 유의한 효과가 존재하는 것으로 나타났으며, 어깨 유연성과 평형성은 수중 태극권 운동 집단이 지상태극권 운동 집단 보다 운동 기간의 경과에 따라 증가하는 경향을 보이는 것으로 나타났다. Tai chi exercise is recommended for elderly women, but it is not clear whether aqua tai chi or land tai chi produces a greater functional physical fitness. The aim of the present study was to compare the effect of the aqua tai chi and land tai chi on variables for functional physical fitness. We carried out a randomized controlled trial study with 26 elderly women who were clinically healthy and divided into the aqua tai chi exercise group (ATCE, n=13) and land tai chi exercise group (LTCE, n=13). Both groups is performed 12 forms of sun-style tai chi for 50-65min, 2 times per week for 32 weeks and test of functional physical fitness were administered before and after 16 week, 32 week trial. Regardless of tai chi exercise group, 6 min walk (p<.007), Dumbbell lift (p<.043), Sit to stand (p<.000), Up and go (p<.003) showed significant difference according to the exercise period. Back scratch showed significant difference (p<.000) according to exercise period and significant difference interaction effect (p<.006). Balancing on one leg showed significant difference (p<.004) according to exercise period, significant differences (p<.045) between exercise group, significant interaction effect (p<.005). It conclusion that regardless of tai chi exercise group, tai chi exercise is improve cardiovascular endurance, muscular strength, agility, dynamic balance in elderly women. And in shoulder flexibility, balance, aqua tai chi exercise group showed a higher trend than land tai chi according to the exercise period.

일본의 장애인자립지원법 위헌소송과 시사점: 장애인복지서비스의 공적책임과 이용자부담을 중심으로

김광래(Kim Kwang Lae) 사회복지법제학회 2018 사회복지법제연구 Vol.9 No.3

일본의 장애인자립지원법(障害者自立支援法, 2006년 시행)은 입법과정에서 충분한 실태조사를 실시하지 않고 장애당사자의 의견을 거의 반영하지 않음으로써 졸속하게 제도를 시행했다는 비판을 받아왔다. 특히 그 과정에서 도입된 이용자부담방식인 정률부담방식은 장애인과 가족들에게 큰 혼란을 초래하였고, 생활에 악영향을 주었으며 장애인이 인간으로써 가져야할 존엄성을 크게 회손 하는 결과를 초래하였다. 이러한 문제에 대하여 장애당사자에 의해 제기된 장애인자립지원법에 대한 위헌소송이라는 장애인운동을 통해 일본정부로부터 장애인자립지원법의 폐지와 신법의 제정에 관한 약속을 이끌어 냈다. 그러나 실질적으로 제정된 장애인종합지원법(障害者總合支援法, 2012년제정)은 장애인자립지원법의 연장선상에서 골격제언과 장애인권리협약은 철저히 배제되었다. 따라서 본 연구에서는 일본에서 나타난 장애인운동이 장애인복지서비스정책에 어떠한 변화를 가져왔는지 그 과정을 살펴보고, 일본에서 장애인복지서비스의 본질을 고찰함으로써 이를 통해 국내 장애인복지서비스정책과의 문제점 및 대응방안을 위한 함의를 도출하고자 한다. 장애인자립지원법에 대한 위헌소송의 쟁점과 기본합의문서, 그리고 골격제언의 내용을 검토해보면 아래와 같이 일본에서 장애당사자의 니즈가 반영된 장애인복지서비스의 본질을 다음과 같이 도출해 볼 수 있다. 첫째, 장애인복지서비스는 장애인에게 생존을 위한 최소한의 도구이다. 둘째, 장애는 자조(自助)보다 공조(公助)의 측면에서 접근해야한다. 셋째, 장애인복지서비스의 철저한 공적책임과 공비부담의 실현이다. 우리는 일본의 장애인자립지원법 위헌소송의 사례를 통해서 장애당사자와 가족에게 장애인복지서비스가 갖는 의미를 검토해 보면 정부가 장애인에게 복지서비스를 제공하는 것은 그들에게 이익이나 수익을 제공하는 것이 아닌 생존권의 보장이라는 측면에서의 접근해야 한다는 것이다. 따라서 장애인복지서비스의 본질은 일본의 장애인위헌소송에서 알 수 있듯이 국가의 책임을 기반으로 장애인의 생존권을 보장하고 사회의 구성원으로서 참여할 수 있도록 지원하는 보편적 사회보장서비스라고 할 수 있다. 그러므로 그 어떤 방법으로도 장애인의 서비스 이용을 방해하거나 저해해서는 안된다는 점을 시사하고 있다. Japan’s Services and Support for People with Disabilities Act (enforced in 2006) has been criticized for being handled with more haste than caution, as not enough research was conducted and opinions from disabled were not reflected. Especially the user’s burden of a fixed rate created a chaos among the disabled and their families, negatively impacted their lives, and violated human dignity. Through the Peoples with Disabilities Movement, unconstitutionality suit of Services and Support for Peoples with Disabilities Act, proposed by the disabled on such matter, has resulted gaining a promise from the government on abolition of the legislation, as well as legislation of new act. However, newly legislated Comprehensive Welfare Act for Peoples with Disabilities (established in 2012) was only an extension of Services and Support for Peoples with Disabilities Act, and left out structural proposal and agreement of rights of disabled. In this research, we will look into the process of changes that the Peoples with Disabilities Movement brought to welfare service policy for disabled. By looking at essence of Japan’s welfare service policy for the disabled, we would also like to draw out undertones of problems and countermeasures for Korea’s welfare service policy for the disabled. By reviewing issues of the unconstitutionality suit of Services and Support for Peoples with Disabilities Act, basic agreement documents, and contents of structural proposal, we can conclude essence of Japan’s welfare service policy for disabled that reflect needs of disabled as below. First, welfare service policy for the disabled is a very basic tool for survival for the disabled. Second, disabilities should be approached from public perspective, not self-help. Third is implementation of public responsibility and burden of payment for welfare service policy for disabled. By reviewing the meaning of the welfare service policy for the disabled to the disabled and their families, through the case of the unconstitutionality suit of Services and Support for Peoples with Disabilities Act in Japan, we can conclude that government providing welfare service to disabled is not from the perspective of providing benefit or profit, but of securing right to live. Hence, as we can conclude from the unconstitutionality suit of the disabled in Japan, the essence of a welfare service for the disabled is a universal social security service that supports and secures the disabled with their rights to live and participate as members of society. It is implied that in any ways and means, distrusting, or impeding service use of the disabled should not be allowed.
