Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

Aplasia cutis congenita is a disorder of heterogeneous group characterized by isolate or multiple, localized or widespread areas of skin defect at birth. Since the first report by Cordon in 1767, it has been relatively rarely reported disorder abroad as well as domestically . It has several clinical subtypes classified by the location and pattern of skin absence, the presence of associated malformations and the mode of inheritance with unknown cause. We had a newborn male infant with this disorder clinically diagnosed, who showed wide full thickness skin defects on right knee and medial surface of ankle from birth, that covered with thin yellowish membrane and showed focal ulcerative area. On his familial history, there were four aplasia cutis congenita patients in the patient's mother in his maternal family side through four generations. Patient mother showed wide spread atrophic scarred looking appearance on her right lower leg. Chromosomal analysis revealed as normal male karyotype. The biopsy of lesions showed ulcerated surface and underlying chronic inflammation with total absence of epidermis. He had no associated congenital anomaly. The lesions healed rapidly for four weeks by conservative treatment as moist wound dressing and systemic antibiotic administrations. As a relatively uncommon skin anomaly, one case of aplasia cutis congenita is reported with review of references.

This study was conducted to examine aspects of health service availability and the satisfaction level of clients of public health centers. 351 clients who visited health centers located in Kyungsan, Chongdo, Youngchon, Kyungju, and Pohang were selected as subjects of this study. Data were collected from March 2, 2000 to April 15, 2000. The results of this study are summarized as follows. 1. 89.5% of them had experience in utilizing health services in public health centers. The rate of availing themselves of public health centers by their own decisions was highest (49.4%). 39.8% of them replied that it took below thirty minutes to visit public health centers. 42.2% of them visited public health centers to be vaccinated. 38.0% of them wanted Oriental medicine to be introduced in public health centers. 30.7% of them thought that doctors need go and see patients at their houses and 31.6% of them was satisfied with present office hours. 39.2% of them was not satisfied with the health services because public health centers were ill equipped. 65.1% of them received medical care in public health centers due to low medical charge and 91.0% of them replied that they would visit again public health centers. 35.5% of them thought that medical equipments must be increased to improve health services of public health centers. Each of the above rates were highest in each variables. 2. According to the satisfaction level with health services of public health centers, 35.2% of them was satisfied, while 9.0% of them was not satisfied. 5.7% of them was very satisfied, while 3.0% of them was not satisfied at all. 47.0% of them was satisfied only to a usual extent. 3. The variables, which significantly influenced the satisfaction level with availability of public health centers, were 'reliance on the medical staff (b=0.1749)', 'sufficiency of nurse's explanation (b=0.2093)', 'medical technician's kindness (b=0.1557)', 'simplicity of medical care procedure (b=0.2036)', 'level of medical charge (b=0.1393)', and 'satisfaction with effect of treatment (b=0.1690)'. 4. The variables, which displayed significant correlation with the satisfaction level with availability of public health centers, were 'necessity of doctor's visit to patients' houses (r=0.229)', 'reliance on the medical staff (r=0.488)', 'sufficiency of doctor's explanation (r=0.495)', 'nurse's kindness (r=0.441)', 'sufficiency of nurse's explanation (r=0.458)', 'medical technician's kindness (r=0.326)', 'the staff's kindness in civil service office (r=0.352)', 'simplicity of medical care procedure (b=0.338)', 'environment of waiting room (r=0.283)', 'convenience of availability of subsidiary facilities (r=0.275)', 'level of medical charge (r=0.335)', 'location of public health center (r=0.173)', 'medical facitities and equipment (r=0.217)', 'treatment methods (r=0.294)', and 'treatment effect (r=0.359)'. It appeared that the community residents were somewhat unsatisfied with public health centers because of problems of equipment, treatment sphere, treatment procedure, and medical personnel. Therefore. The government must focus on increase and modernization of medical equipments, the establishment of oriental medicine, and increase of medical personnel. It is important for public health centers to provide community residents with better health services in order to meet their health needs.

장애인복지의 정책적 과제와 지역적 현안

황성철 新羅大學校 1996 論文集 Vol.41 No.1

Although progress has been made in developing social welfare policies for the disabled during the last 10 years or so, especially current government's efforts to bring about drastic changes of social welfare policy structure, there has been little research focusing on analying and formulating specific policy agenda for the disablities. Thus, the purpose of this paper is to examine and analyse current social welfare policies for the disabled in terms of the core criteria that are generally applied to evaluate social welfare policy. This paper also identifies key policy agenda in the course of analysing and evluating some of the important welfare policies for the disabled such as income maintenance, health, and employment policy, social service, and public social service delivery system. At present time, a variety of problems in the national and regional social welfare policies for the disable are found. The provisions of income maintenance and health policies are not adequate enough for the disabled to maintain the national minimum and exclude many other disablities suffering from poverty and illness due to the failure of registration policy of the disabled and unresonable poverty line set up by the government. Problems of inequality and ineffectiveness are also found in the rehabilitation employment services for the disablities. Social service delivery systems are so fragmented that the disabled could get an easy access to the needed services. It is suggested that under the rubric of partnership between national and regional government, several functions of national government should be transferred to the regional government. It is important to note that the specific policy agenda identified in this paper should be fully considered in the discussion of changing national and regional social welfare policies for the disabled and the direction of the policy change should be set in response to the utmost needs of the disabled.

황승욱,김현주,홍성철,이상이 제주대학교 생명과학연구소 2002 제주생명과학연구 Vol.5 No.6

연구배경 : 최근 청소년 연령층의 비만이 급격히 증가하고 있으며, 비만 청소년들에 있어서 고혈압, 당뇨, 고지혈증이 조기에 발현될 뿐 아니라 성인비만과 성인병 발생의 주 원인이 되고 있다. 본 연구는 제주도내 고등학생들의 비만 유병률과 청소년 비만과 심혈간 위험인자인 혈압, 총콜레스테롤, 공복시혈당의 관련성을 알아보고 소아비만과 청소년 비만의 관련성을 조사하였다. 방법 : 연구대상은 제주도내 22개 고등학생 1학년 6,064명을 대상으로 하였고. 체격조사는1999년도 학교 신체검사 자료와 병원 건강검진 자료를 이용하였다. 비만에 대한 평가는 대한소아과학회에서 발행한 1998년도 한국소아표준치와 체질량 지수 두가지를 이용하였다 심혈관 위험인자로는 총콜레스테롤 수축기 혈압, 이완기혈압 공복시 혈당으로 하였으며, 배상자중 646명에 대해 과거 건강기록부를 열람하여 초등학생 때의 비만실태를 조사하였다. 결과 : 제주도 고등학생의 비만 유병률은 표준체중에 의한 비만 산출법으로는 남, 여학생 각각 12.6%, 13.3%이었고 체질량 지수에 의한 비만 위험군 및 비만 학생이 남, 녀 각각 12.7%, 13.4%로 나타났다. 지역에 따른 비만 유병률은 남학생의 경우 시 지역 12.9%, 군 지역 10.3%로 시 시역에서 비만 유병률이 유의하게 높았으며, 여학생의 경우 시·군지역 각각 12.9%, 14.2%이었으나 통계적 유의성은 없었다. 고등하교 계열에 따른 비만 유병률은 남학생의 경우 인문계 13.9%, 실업계 10.1%로 인문계가 유의하게 높았으나, 여학생의 경우는 통계적 유의성은 없었다. 비만 정도에 따른 심혈관 위험인자와의 관련성에서 남학생의 경우 수축기와 이완기혈압, 공복시혈당, 총콜레스테롤 수치가 비만 정도에 따라 유의한 차이를 보였으며(P<0.05), 여학생의 경우 공복시혈당을 제외한 나머지 변수에서 유의한 차이를 보였다. 체질량지수와 심혈간 위험인자간의 상관관계에서 남학생은 혈압, 공복시혈당 총콜레스테롤이 유의한 양의 상관관계를 보였으며, 여학생의 경우 공복시혈당 외에 다른 수치에서 유의한 양의 상관관계를 보였다. 연구대상자 중 646명에 대해 초등학교 1학넌 때의 비만실태를 추적한 결과 초등학생 비만이 고등학생 비만에 미치는 비교위험도가 남녀 각각 3.77, 2.16으로 유의하게 나타났다(P<0.05). 결론 : 제주도지역 고등학생들의 비만 유병률이 상당히 높게 나타났고, 청소년 비만과 심혈관 위험인자간의 관련성을 알 수 있었다. 또한 소아비만이 청소년 비만으로 상당수 이행되었으므로 소아 및 청소년기에 적절한 비만관리 프로그램이 요구된다. Background: Recently, adolescent obesity was increased and tended to become obese adults, facing increased risk for diabetes, cardiovascular disease. Even vefore reaching adulthood, adolescent, obesity already was experiencing hypertension, dyslipidemia, and diabetes mellitus. The purpose of this study was to find prevalence of obesity of high school students in Jeju island and association between obesity and cardiovascular risk factors and association between childhood obesity and adolescent obesity. Method: The study subjects were 6,064 students of twenty-two high school in Jeju island and health survey data was gathered from high school health examination data and hospital health examination data from Aug. 1999 to Dec. 1999. Adolescent obesity was evaluated by ideal body weight method in 1998 and body mass index. Cardiovascular risk factors were checked total cholesterol, systolic and diastolic blood pressure, fasting blood sugar. In 646 students, obesity at primary school is checked by primary school health record. Results: Prevalence of obesity in Jeju island high school students was 12.6% in male students, 13.3% in female students by ideal body weight method and Prevalence of obesity risk and obesity was 12.7% in male students, 13.4% in female student by body mass index. Prevalence of obesity of male students in city area and district area of Jeju island were each 12.9%, 10.3% and that of male students in city area was significantly higher. Prevalence of obesity of female students in city area and district area of Jeju island were each 12.9%, 10.3% and that of male students in city area was significantly higher. Prevalence of obesity of female students in city area and district area of Jeju island were each 12.9%, 14.2% and not significantly different. Prevalence of obesity of male students in general and commercial school group were each 13.9%, 10.1% and that of general school group was significantly higher. In female students, Prevalence of obesity general and commercial school group was not significantly different. Total cholesterol, systolic and diastolic blood pressure were significantly associated with degree of obesity in male and female students(P<0.05) and fasting blood sugar was only significantly associated with degree of obesity in male students (P<0.05). In 646students, Relative risk of obesity at primary school and that at high school in male and female students were 3.77, 2.66 and was significantly associated. Conclusion: Prevalence of obesity of high school students in Jeju island is very high and adolescent obesity was significantly associated with cardiovascular risk factors. Mostly childhood obesity tended to become adolescent obesity and program of control of obesity at childhood and adolescence is required.

벼와 피에서 제초제 alachlor의 선택적 작용

황을철,우승희 東亞大學校生命資源科學大學附設 農業資源硏究所 1995 農業生命資援硏究 Vol.4 No.1

벼와 피에서 α-chloroacetamide계 제초제의 선택적 작용, 특히 포장에 이앙하는 어린모의 벼(약 40일묘)와 발아중인 피에서 alachlor의 선택적 작용이 발현되는 근거를 찾고자, 벼와 피에서 몇가지 생화학적 차이를 조사하였다. 제초제 alachlor에 의한 약해는 생장일수가 동일한 유묘기의 벼와 피에서는 비슷하였으나, 생장일수가 서로 다른 40일묘의 벼와 7일묘의 피에서는 현격한 차이가 있었다. Alachlor에 대하여 약해정도가 현격히 다른 40일묘의 벼와 7일묘의 피체내의 GSH 함량과 GST 활성은 서로 비슷하였으며, alachlor 처리에 의한 GSH 함량과 GST 활성의 증가도 모두 미미하였다. 40일묘의 벼와 7일묘의 피에서 alachlor 처리에 의해 저해되는 α-amylase의 활성은 무처리에 비해 각각 93.5%와 70%로 현격한 차이를 나타내었으며, 이는 약해정도와 부합하였다. 따라서, 40일묘의 벼와 7일묘의 피에서 발현되는 alachlor의 선택성 또는 벼를 이앙한 포장에서 발아중인 피를 방제하는 α-chloroacetamide계 제초제의 선택성은, 벼와 피체내의 방어계인 glutathione conjugation 반응에 기인하는 것이라기 보다는, 종실내의 주된 저장영양분인 탄수화물의 이용에 관련된 효소인 α-amylase가 저해되는 정도에 기인하는 것으로 판단되었다. Several biochemical differences between rice and barnyardgrass which were related to glutathione conjugation and utilization of starch reserves in seeds were examined to investigate the selectivity of α-chloroacetamide herbicides in rice and barnyardgrass, especially in transplanting staged rice (about 40-day-old) and germinating barnyardgrass. Phytotoxicities of alachlor to rice seedlings and barnyardgrass seedlings were all severe at stronger concentration that 1.0×10-6 and were similiar to each other at various concentrations. However, 40-day-old rice which was independent on the seed reserves was tolerant to alachlor. Glutathione(GSH) content and activity of glutathione S-transferases(GST) in roots of rice seedlings and barnyardgrass seedlings were similiar to each other, and those of 40-day-old rice and barnyardgrass seedlings which were observed to show different responses to alachlor were so. Moreover, the inductions of GSH and GST in 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor were insignificant. On the other hand, activities of α-amylase in seeds of 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor decreased to 93.5% and 70.0% of the control respectively. These results were consistent in phytotoxicities above stated. It was therefore stated that the selectivity of alachlor, α-chloroacetamide herbicide in 40-day-old rice and germinating barnyardgrass was due to inhibition degree of α-amylase needed for starch utilization as energy sources in grass germlings, rather than due to the rate of glutathione conjugation generally considered as main factor contibuting to α-chloroacetamide herbicide detoxification and selectivity.
