The issues for the aged have been appearing on the stage as the deep social problems since the end of 1970's when our communities began to enter into high level industry, which were concerned by people in modern times. The starting time to study on the aged in Korea was from the 1960's. Moreover, it was lively proceeded during the end of the 1970's and the 1980's. At first, it mainly dealt medical issues for them, then, spread up to their social concerns later. This study was to research about the participating type of the aged' leisure, sports activities, as well as its changable relationships with life satisfaction on the premise regarding the necessity of positive practice toward leisure and its participation as the positive solution scheme from the aged' issues, which was based on the social concerns related with the aged. According to the questionary method, to select the main group who were over 60-years-old, men and women in Pusan, it was studied and analyzed regarding the realities of the aged's leisure activities, the participating attitude in sports, the relationships between the degree of satisfaction life when participating in sports activities and the life satisfaction. The results were as follows ; 1. Among the low ranking scopes of the participating attitude in sports, in case of participating in sports for the self-training of character-building themselves, it significantly had and effect on the satisfaction of life. 2. In case of building their own character through sports activities, it had the highest effect on the satisfaction of life. 3. The satisfaction of sporting activities in their childhood had and effect on the life satisfaction.

정종학,김창윤,사공준 大韓産業醫學會 1994 대한직업환경의학회지 Vol.6 No.2

유기용제폭로 근로자에 있어서 신경행동기능과 자각증상을 평가하기 위하여 1992년 10월부터 경상북도 구미시의 모 비디오테이프 제조공장에서 톨루엔, 시클로헥사논, 메틸 에틸 케톤에 주로 폭로되는 근로자들을 폭로군(고폭로군 45명, 저폭로군 44명)으로 하고 동일 공장 내 다른 부서의 생산직 근로자 43명을 대조군으로 하여 단면조사연구를 실시하였다. 신경행동검사는 개인용 컴퓨터와 신경행동검사용 컴퓨터 프로그램 Swedish performance evaluation system을 이용하여 단순반응시간(simple reaction time), 선택반응시간(choice reaction time), 숫자구분(digit classification), 손가락민첩성(finger tapping speed), 숫자더하기(additions), 부호숫자짝짓기(symbol digit)와 숫자외우기(digit span), 7가지의 신경행동검사를 시행하고 인구학적 변수와 작업과 관련된 변수를 조사하였다. 16문항의 설문지(Scandinavian questionnaire 16)와 신불안우울척도(New Anxiety - Depression Scale)를 이용하여 자각증상과 감정상태를 측정하였다. 조사대상의 평균연령은 29세, 평균근무년수는 5.4년으로 세 군간에 차이가 없었으며 83%가 남자였고, 85%가 고등학교 졸업자였다. 자각증상에 있어서 연령, 성, 교육수준, 음주여부를 보정한 후 유기용제 폭로수준에 따라 호소율의 차이를 보이는 항목은 없었고 총 증상점수 역시 폭로수준에 따라 유의한 차이가 없었으며 신불안우울척도에 있어서도 문항이나 총점수에서 유의한 차이가 없었다. 신경행동검사의 단순비교에서 선택반응시간, 숫자구분, 숫자더하기, 부호숫자짝짓기의 반응시간이 폭로수준이 증가할수록 유의하게 길어졌으며 단순반응시간, 손가락민첩성, 숫자외우기는 유의한 차이를 보이지 않았다. 측정치 중 반응시간의 표준편차나 잘못 반응한 횟수는 세군간에 유의한 차이를 보이거나 일정한 경향을 나타내지 않았다. 신경행동검사 항목들에 대한 요인분석에서는 숫자더하기, 부호숫자짝짓기, 숫자외우기가 "기억력관련요인", 양 손의 손가락 민첩성이 "협조운동관련요인", 단순반응시간, 선택반응시간, 숫자구분이 "반응속도관련요인"으로 분류되었으며 세 요인에 의한 설명력은 62.6%였다. 연령, 성, 교육수준 및 컴퓨터에 대한 친숙도 등을 보정한 후에도 선택반응시간, 숫자구분, 숫자더하기, 부호숫자짝짓기의 반응시간이 폭로수준에 따라 유의한 차이를 보였으며 열수의 손가락민첩성과 "기억관련요인", "반응속도관련요인"의 요인점수가 유의한 차이가 나타내었다. 잘못 반응한 횟수는 남자보다 여자에서 많았으며 교육수준이 낮을수록 복잡한 검사에서 잘못 반응한 횟수가 많았다. 컴퓨터에 대한 친숙도가 클수록 잘못 반응한 횟수가 적고 비교적 복잡한 검사항목에서 반응시간이 짧았다. 흡연군이 비흡연군에 비해 손가락 민첩성에서 두드림 횟수가 유의하게 적었다. 자각증상의 호소율은 신불안우울척도와는 높은 상관관계를 보였으나 신경행동검사 측정치와는 낮은 상관관계를 보였고 증상의 호소율이 높을수록 반응시간은 길어지고 두드림 횟수가 적어지며 숫자외우기의 숫자의 길이가 짧아지는 경향을 나타내었다. 7 가지 검사항목 중 부호숫자짝짓기의 반응시간이 폭로수준, 연령, 성, 컴퓨터에 대한 친숙도의 차이에 따라 가장 민감하게 변화하였다. A cross-sectional study was performed to evaluate the effects of chronic exposure to solvent on neurobehavioral performance of solvent exposed 89 workers engaged in a video tape manufacturing factory. A control group of 43 workers was selected from different sections of the factory. The mean age ad the mean duration of employment were 29 years and 5.4 years. Each worker completed a medical and occupational questionnaire. Adverse effects on the central nervous system were assessed by self reported Scandinavian questionnaire 16, New Anxiety - Depression Scale and seven tests of Swedish Performance Evaluation System. These included simple reaction time, choice reaction time, digit classification, finger tapping speed, additions, symbol digit and digit span. Several potential confounding factors were included as independent variables in all analysis of neurobehavioral tests and symptoms. These included age, sex, educational level, familiarity with computer, alcohol drinking and amount of smoking. No significant associations were found between solvent exposure and total symptom score and mood score. Although the mean duration of employment was 5.4 years, comparison of mean performance scores for confounding factors showed a significantly poorer performance on choice reaction time(P<0.05), digit classification(P<0.01), additions(P<0.01) and symbol digit(P<0.01) in exposed group. Factor matrix of neurobehavioal tests produced by varimax rotation showed three distinct factors, which correspond to assessments of "memory", "coordination" and "response speed". These factors accounted for 62.6% of the total variance of the sample. Familiarity with computer was found to be associated with performance of symbol digit and amount of smoking appeared to slow finger tapping speed. Male and college graduate workers have less errors than others. These were no significant correlation between neurotoxic symptom score and performance of neurobehavioral tests.

객체지향 데이타베이스의 중포속성에 대한 다차원 색인기법

This paper proposes multidimensional indexing techniques for nested attributes in object- oriented databases. We use a multidimensional dynamic file organization for these indexing techniques. Since most conventional indexing techniques for object-oriented databases use a one-dimensional index structure such as the B+-tree, they do not often handle complex queries involving both nested attributes and class hierarchies. We extend a tunable two-dimensional class hierarchy indexing technique for nested attributes in object-oriented databases. The tunable two-dimensional class hierarchy index is an indexing scheme that deals with the problem of clustering objects in a two-dimensional domain space that consists of a key attribute domain and a class identified domain for a simple attribute in a class hierarchy. In our extended scheme, we construct indexes using multidimensional file organizations that include one class identifier domain per class hierarchy on a path expression that defines the indexed nested attribute. This scheme supports efficiently queries that involve search conditions on the nested attribute represented by an extended path expression. An extended path expression is a one in which a class hierarchy can be substituted by an individual class or a subclass hierarchy in the class hierarchy.

朴鍾鶴,孫彰奎,趙鍾寬 대전대학교 한의학연구소 2001 한의학연구소 논문집 Vol.9 No.2

A literature study on oncological immune therapy was done, and the results were as follows. 1.Oncological immune therapy is classified as specific·non specific therapy or active·inactive therapy, and in tumor immune response, cellular immunity operates mainly, so activity of T lymphocytes and macrophages are closely related with growth, progress, metastasis and prospect of tumor. Recently, Immune therapies of gene which use cytokines and HLA-B7 are carrying out. 2.In oriental medicine, development of disease is closely related to up and down of healthy qi, so healthy qi operates as a immune factor and resistance factor. 3.On the base of theory "Increasing healthy qi reduces mass(養正則積自除)", strengthening body resistance is emphasized in cancer therapy. Also strengthening body resistance activates cellular immune response and promote killing tumor facility of T-cell. 4.In clinical view, using immune therapy after operation, radiation, and chemotheraphy is more effective than immune therapy itself, so it is expected that east-west cooperation will be effective in cancer therapy. 5.The study of oncological immunity is progressed on emphasizing T-cell and it is related to oriental medical theory "strengthening healthy qi to eliminate pathogen(孵正祛邪)" and advanced study is expected in future.

생체용 Ti₁-x-Zrx합금의 기계적 성질과 내부식성

정종현,백승남,노학,고영무 대한치과기재학회 1998 대한치과재료학회지 Vol.25 No.1

While titanium and its alloys has been well studied for a long time, new interest in these materials and their properties has arisen in recent years with respect to their application as biomedical metallic materials. For practical purposes, the following performances are essential for biomaterials. (1) low specific gravity (2) high corrosion resistance (3) good biostability and biocompatibility (4) sufficient mechanical properties (5) non-toxicity To develop biomedical implant materials having all the properties mentioned above, new titanium-zirconium alloys were prepared in this study. Mechanical properties and corrosion resistance were then investigated for as-cast and as-homogeneized Ti₁_x-Zrx alloys in order to reveal their possible use for biomaterials. From the experiments, the following results are obtained: 1. No martensite structure are observed in the specimens made of pure Ti and Zr. In contrast them, Ti-Zr alloys containing 18wt%Zr, 24wt%Zr and 48wt%Zr show a kind of martensite structure regardless heat treatment. 2. Fineness of structures for as-cast-alloys seems to vary with alloy composition. Ti-Zr alloy containing 48wt%Zr shows the finest microstructure. 3. Hardness of Ti-Zr alloys shows continuous change through the system and the alloys containing 48 to 60wt%Zr indicate higher hardness compared with those of pure Ti and other alloys. It is well known that hardness is usually changed with substitutional atoms, and effect of solute atom on hardness is greatest with an equi-atomic composition. The greatest hardness which was obtained in Ti-Zr alloys containing 48 to 60wt%Zr is therefore reasonable. Also, enhanced hardness can be explained on elastic interaction between dislocation and substitutional solute atoms in crystal structure and on fineness of structure. 4. Pure Ti and Zr alloys containing 6wt%Zr, 12wt%Zr, 18wt%Zr, 36wt%Zr show better corrosion resistance compared with those of pure Zr, stainless steel(SUS 316L) and the Ti-Zr alloy containing 48wt%Zr. 5. Comparing hardness, microstructure and corrosion of Ti₁_x-Zrx alloys, no large differences between as-cast and as-homogenized alloys are seen.

신종원,유학선,공현희,정동일 慶北大學校 醫科大學 1996 慶北醫大誌 Vol.37 No.3

목적 : 국내에 시판되고 있는 콘택트렌즈 보존 및 소독액, 그리고 아메바성 각막염의 치료제로서 인정받고 있는 polyhexamethylene biguanide (PHMB)의 가시아메바 포낭에 대한 살충효과를 평가하고자 한다. 대상 및 방법 : 카스텔라니가시아메바 Ma주, 대식가시아메바 Nagington주 및 담수가시아메바 KA/LI주에 대한 소독액의 살충효과의 평가는 한천 plate위에서 수행하였고, 최저살충농도(minimal cysticidal concentration : MCC)의 결정은 microplate를 이용하였다. 7일간 관찰 후, 탈낭하지 않는 가시아메바 포낭은 사멸한 것으로 판정하였다. Chlorhexidine 및 PHMB의 MCC를 결정하기 위해 8시간 및 48시간 처리 실험을 분리하여 시행하였다. 결과 : 시판 소독액 중 chlorhexidine과 thimerosal를 함유하는 용액 C만이 가시아메바 포낭에 대한 살충효과가 있었고, 나머지 3종의 소독액은 살충효과가 없었다. 0.02% PHMB로 4시간 이상 처리한 가시아메바 포낭은 충주에 관계없이 사멸되었다. Chlorhexidine 과 PHMB, 두 약제 모두 8시간 처리 MCC가 48시간 처리 MCC보다 다소 높았다. PHMB에 대한 감수성은 가시아메바 충주에 따라 차이가 격심하였다. 결론 : 3종 가시아메바 포낭에 대한 PHMB의 MCC (0.29∼9.38㎍/㎖)가 chlorhexidine의 그것(2.73∼18.75㎍/㎖)보다 낮아 PHMB는 아메바성 각막염의 치료제 및 콘택트렌즈 소독제로 사용 될 수 있을 것으로 사료되며 화학소독액에 PHMB를 10㎍/㎖ 첨가하는 것이 요망된다. In order to evaluate the cysticidal effects of contact lens disinfectants and polyhexamethylene biguanide(PHMB) against 3 clinical isolates of Acanthamoeba. in vitro cysticidal assay was performed on agar plates covered with heat-inactivated Escherichia coli. Three clinical isolates of Acanthamoeba were A. castellanii Ma strain. A. polyphaga Nagington strain, and A. lugdunensis KA/LI strain. After treatment of Acanthamoeba cysts with the disinfectants or PHMB, the cysts were cultivated for 7 or more days. Cysts which were not excysted in 7 days after treatment were recognized killed. Among commercial disinfectants, the solution C. which contains chlorhexidine and thimerosal. was the only one with cysticidal effects on Acanthamoeba cysts. PHMB of 0.02% concentration was also cysticidal. Sensitivity to PHMB varied profoundly from isolate to isolate. Minimal cysticidal concentration (MCC) of chorhexidine and PHMB were determined by cultivation of cysts treated for 8 or 48 hours with serially diluted chlorhexidine and PHMB in wells of a 96-well microplate containing axenic culture media for amoebae. MCC of 48-hour treatment with both chemicals was lower than that of 8-hour treatment. MCC of PHMB against amoebic cysts was lower than that of chlorhexidine. In the light of these results. PHMB could be a contact lens disinfectant as well as a chemotherapeutic agent of amoebic keratitis.
