In order to investigate the structures and dynamics of phytoplankton communities, each physicochemical environmental factor, species composition, standing crop, and dominant species were examined in the marine ranching ground of Tongyeong coastal waters from April to October, 2000. During the studies, mean water temperature and salinity were $18.8^{\circ}C$ and 33.1 psu, respectively. DO, SS and transparency varied from 5.43 to 11.39 mg/l, 14.6 to 32.4mg/l and 3.5 to 9.0m, respectively. Light intensities varied from 0.02 to $966{\mu}E/m^2/s$, which decreased with depth. $NH_4-N,\;NO_3-N,\;NO_2-N,\;PO_4-P,\;and\;SiO_2-Si$ were fluctuated from 0.059 to 0.332 mg/l, 0.040 to 0.800 mg/l, 0.001 to 0.468 mg/l, 2.3 to $143.0{\mu}g/l$, and 0.007 to 0.600 mg/l, respectively. chlorophyll a concentrations were fluctuated from 0.7 to $8.9{\mu}g/l$. Among 130 taxa of phytoplankton communities observed. diatoms occupied more than 81.54% of the total species, and the others were dinoflagellates and silicoflagellates. Phytoplankton standing crops ranged from $4.6{\times}10^4\;to\;2.6{\times}10^6cells/l$. In October, the standing crops were at bloom level showing more than $10^6cells/lat$ all stations. Dominant species changed by month and station. Leptocylindrus danicus occupied 59.84% in April and 22.03% in June. Pseudo-nitzschia pungens in August and Chaetoceros socialis and Skeletonema costatum in October were predominant species. In order to investigate factors influencing the total phytoplankton standing crops the correlations between the standing crops of diatoms, dinoflagellates, all phytoplanktons occurred and environmental factors were calculated using a multiple regression analysis. The coefficient of determination $(R^2)$ for total standing crops was 0.63 which explained 63% of variance and that of $R^2$ for diatom was 0.82. In statistical analysis, the results showed that the environmental factors influencing the size of the communities were predominantly water temperature, salinity and silicate.

The purpose of this study was to investigate the change of clothes in modem Korean women in terms of a socioeconomical background, the introduction to western clothes, and the improvement of clothes between the opening period of ports in the early 1900's and 1960's. In addition, the study investigated how western clothes became popular in a Korean society along with the traditional' Korean clothes, Hanbok. The radical social change since the opening of ports motivated the change in the way of Korean women's thinking, and consequenty the improvement of Hanbok which developed into the clothes-improvement-movement. It was not until 1905 that the improvement of clothes was hotly debated particularly in the matter of abolishing Jangeui and the extreme length of Jeogori and Chima. The Tongchima-Jeogori style which lengthened Jeogori and shortened Chima was widely accepted as everyday wear until the western clothes substituted them after the Independence from Japanese Conquest. As the length of Chima shortened, there occurred a change in Boson and Jipsin as well. There appeared shoes and Gomoosin in place of Jipsin, socks in stead of Boson and were popularized until after the Liberation in 1945. The popularity of Gomoosin diminished markedly with the diversification of shoes styles, due to the improvement of the standard of living with economic development in the 1960's. The traditional Hanbok was gradually differentiated according to the social status, for instance student, teachers, ordinary women, girls and Kisaeng. Especially since the white clothes caused much trouble in washing and sewing, there came into being the movement of wearing colorful clothes. The Movement of abolishing white clothes and promoting of wearing colorful clothes was enforced during the period of Japaness conquest from the 1920's to the Liberation, which consequently stimulated an interest for colors of clothes. The period under the war between 1937 and 1945 was especially noted for the extreme regulation over the clothes. The Japanese government forced each group of women, e.g., girl students, a young women's association, school teachers, and ordinary women and girls, to wear their own uniforms. Also, It recommended the use of Tongchima in stead of long skirts, and buttons in place of Coreum so as to conserve textile encouraging the use of other substitutes to save resources. The western clothes, a model of clothe's improvement was deemed as a symbol of modernization and enjoyed general popularity. The supply of relief clothes after the Korean war accelerated the expansion of western clothes even further and the trend of westernization along with economic progress in the 1960's resulted in wearing of western clothes as everyday dress. The expansion of western clothes as casual wear rapidly diminished wearing of Hanbok which in turn took the position of ceremonial dress worn in special cases only. Hence the Korean women's clothes were dualized into traditional Hanbok and western clothes and the western clothes that stems on its convenience was settled as everyday wear where as the Hanbok appeared as ceremonial dress stressing on ornamental features. As mentioned aboved, we are able to discovered an orientation in the course of transitional process of modern Korean women's clothes admist diversified changes, which is a consistent pursuit of convenience and practicality based upon progmatism. The trend such as this carne into a finale' as women's dress became dualistic in forms of Hanbok and western clothes, and the change since then is supposed to proceed in two forms of dress featuring its own style.

It is considered to be important to create aesthetically beautiful style through the change of external shape, however for the hair stylists, whose beauty expression is through hair, the role of hair doctor is becoming even more important with focus to improve the hair healthiness. Hair clinic is management of hair and scalp. It is the management process of preventing damages, while improving and cultivating healthy and shiny hair. The current concept in hair management is moving from simple hair styling to emphasis at hair management. As far as hair management is concerned, it usually includes treatment tools such as shampoo, conditioner, hair treatment and scalp scaling system, which is used for diagnosis of hair condition in order to treat the scalp. As the interest of hair healthiness becoming more wide spread, so does the breadth of clinic menu. The wide choice is to fulfill the profound desire of people, whose demands are simply to have variety in their choice. This is resulting in faucets of new value-added and differentiated products. The values that make-up the hair styles consist of mainly design (trend, preference), function(styling, management convenience) and clinic(hair quality improvement, damage repair). Shampoo and conditioner have gone beyond their original function of cleansing to providing combinational functions of treatment, to care and remedy, and advanced massage effectiveness. These are, to name a few that seem to go beyond their original function to satisfy the mental healthiness in people, the King Kong shampoo of shampooings in forward-backward manner, 5-minute shampoo massage that applies sports and relaxation massage, scalp acupunctural message and aural(ear) massage. More and more people are complaining about the damaged hair and hair loss problems due to perms, dyeing and bleaching of hair, in addition to natural scalp and hair damaging factors. Such complaints have stimulated many beauty products and various hair treatment systems being introduced with focus to provide nutrition and prevent damages to scalp and hair. As the living standards improve and the desire of people is to pursue differentiated lives, their demand also increases in hair styling products to fulfill the needs of healthy and aesthetical aspects of their lives.

하천과 홍수터 생태계에서 생물지형학 연구는 폭 넓은 시공간 차원에서 생물계와 수문-지형체계 사이의 복잡한 다중관계를 다루어 왔다. 본 총설에서는 하천에서 (1) 생물과 수문지형 조건의 다자간 관계, (2) 생물다양성과 서식처 이질성의 관계, (3) 생태계 유형에 대한 교란의 영향에 대하여 설명함으로써 하천지형생물학의 범위와 과정을 논의하였다. 시간적으로 하천의 생물지형 복합체는 지형, 선구, 생물지형 및 생태적 단계의 순서로 전환이 된다. 공간적으로 물 흐름과 유사 분포가 식생과 상호작용하여 하도 지형의 변화가 일어난다. 이렇게 형성된 하천의 공간적 이질성은 하안의 생물종다양성을 증가시킨다. 그러나 댐 하류 하천에서는 서식처 유형과 조건이 심각하게 훼손되어 생물다양성이 저하된다. 우리나라의 하천에서는 최근 국지적 교란과 전 지구적 기후변화로 하안 식생이 번무하고 특히 외래종이 빠르게 정착하고 있다. 따라서 급격한 기후변화와 인류에 의한 압박의 시대에서 하천 생물과 수문지형 조건 사이의 상호 관계를 이해하는 것이 더욱 중요할 것으로 생각된다. 이 총설에서 논의한 하천 생물지형 개념틀은 우리나라 하천의 생태적 관리와 복원에 기여할 것으로 기대된다.

다시마 포자체에서 일어나는 광합성의 계절변화를 이해하기 위해, 1996년 2월부터 7월까지 동남해안에 양성한 엽체들의 광합성과 호흡률을 현장과 일정한 수온 및 영양염 조건으로 실험실에서 매월 측정하였다. 현장에서 측정한 P-I 매개변수는 계절적으로 변화하였다. 광합성력($P_{max}$)은 3월에 6.64 mg $O_2{\cdot}gdw^{-1}{\cdot}h^{-1}$로 최대였고, 이후 지속적으로 감소하였다. 광합성 효율(${\alpha}$)은 0.026~0.106의 범위였고, 광합성력과 유사한 시간변화를 보였다. 호흡률의 시간변화는 광합성력의 변화와 유의한 상관을 가지지 않았다. 호흡률은 0.25~0.83 mg $O_2{\cdot}gdw^{-1}{\cdot}h^{-1}$의 범위였다. 현장에서 측정한 광합성력은 중량의 상대성장률과 높은 상관을 지니고 있어, 광합성력이 증가함에 따라 체내에서 축적되는 물질의 양 또한 증가함을 알수 있었다. 현장과 실험실에서 측정한 광합성력을 비교한 결과, 2월내 현장에서의 광합성력이 낮았던 것은 이 기간 중 낮은 수온에 의한 영향 때문이었고, 3월 이후에 광합성력이 점진적으로 감소하는 것은 엽체의 연령증가에 따라 엽체의 두께가 증가하였기 때문이었다.4월에 측정한 엽체의 크기별 광합성력은 엽체의 두께와 광합성률간에는 음의 상관이 있다는 것을 나타내었다.

본 연구는 1990년대 들어 점차 심각해지고 있는 산재장애인의 재취업실태를 살펴보고, 재취업에 영향을 미치는 요인을 밝혀, 산재보험 재활서비스 체계의 강화하기 위한 개입방안을 제시하고자 하는 데 목적이 있다. 조사대상자는 1996년과 1997년 산재보험 장해보상금 종결자 중 신규장해판정자 1,060명이며 조사방법을 전화면접조사를 사용하였다. 본 연구를 통해 밝혀진 주요 결과를 보면, 첫째, 산재장애인의 재취업율은 자영업을 합쳐 약 28.6%로 전체 응답자의 약 1/3에도 못미치는 낮은 수준이었다. 둘째, 신체적 손실을 나타내는 장해등급 뿐만 아니라 일상생활능력정도 역시 재취업에 유의한 영향을 미치는 것으로 나타났는데, 이는 재취업에 있어 신체적 손상을 보완해 줄 수 있는 재활공학서비스의 중요성을 보여준다. 셋째, 재취업에 있어 신체적인 요인뿐만 아니라 자신의 장애를 수용하는 시기나 자신의 장애를 인식하는 점도 등과 같은 심리적인 요인도 유의한 영향을 미치는 것으로 나타나 재취업에 있어 사회심리적 재활프로그램의 필요성울 확인할 수 있었다. 넷째, 직업재활서비스 이용여부는 재취업에 유리한 영향을 미치지 못하는 것으로 나타났는데, 이는 현재 장애인 직업재활프로그램의 비효과성 측면과 더불어 직업재활프로그램의 저조한 참여에서 기인한 결과로 보인다. 이러한 결과를 통해 얻을 수 있는 함의는, 우선적으로 현재의 산재보험에서 투자하는 재활사업비를 확대하는 방안이 필요하며, 재활공학서비스의 연구개발사업을 활성화시키고, 현재의 산재보험 직업재활훈련체계를 재정립하고 프로그램 개발하는 등의 노력과, 사회심리재활서비스의 산재보험 수가화를 통한 확대, 개별상담원 도입 등의 방안 등을 적극적으로 검토해야 할 필요가 있다는 점이다.

Recently, there has been an increasing need for long-term care and comprehensive health care services in community settings. The Ministry of Health and Welfare introduced the Hospital-Based Home Nursing Care Program in 2000. Before this initiative, there was a Home Nursing Demonstration Center, affiliated with the Seoul Nurse Association, had offered home nursing services with the financial support from the local government. since 1993, the Center's nursing staff has been engaged in a general hospital in an effort to provide home nursing care services within Korea's health care system. The purpose of this study was to analyze and identify characteristics of community-based home nursing care supplied by a community-based home nursing team engaged in a general hospital. Also. visit nursing care services provided by public health centers were evaluated in terms of accessibility and supply versus demand, to enhance the accessibility of low-income patients living in Seoul to home nursing care services. Data were collected from home nursing insurance reimbursement claims submitted by the community-based home nursing care team from March 1 to October 30 in 2001 and a questionnaire survey on home-visit nursing services of 25 public health centers in Seoul. The subjects consisted of 197 patients and 12 public health centers. The result were as follows. First, medical institution's community-based home nursing care program was better in technical quality than health-center-based home-visit nursing care. In addition. the pattern of the subject patients was similar to that of hospital-based home nursing care program. Second, there was a high demand for community-based home nursing care while only a small number of home-visiting nurses served at public health centers in Seoul. As a result, many patients could not receive adequate care. Finally, we suggest that community-based home nursing care program should be introduced in the national health system to meet the at-home care needs of severely ill low-income patients. Furthermore, to better utilize home nursing and visit-nursing care resources and offer continued care for patients in community settings, an efficient referral network should be built among related institutions. This would require improvement of reimbursement system and amendment of the law related to health insurance system and community-based home nursing care services.
