높은 생산성을 위한 인공습지 조성 및 관리 방안 제시를 위해 세 가지 대형정수식물(갈대, 애기부들, 줄)을 두 가지 매질조건(개별 매질과 혼합 매질)과 두 가지 수위 조건(5 cm와 20 cm)에 식재한 뒤 3년간의 모니터링을 수행하였다. 그 결과 줄의 경우 조성 환경에 상관없이 첫 해 초기 생육(최대 초고, 약 200 cm; 최대 지상부 생산성 약 500 $g/m^2$)뿐만 아니라 3년경과 후 최종 생육(줄, 약 1,100 $g/m^2$; 애기부들, 770 $g/m^2$; 갈대, 450 $g/m^2$)에 있어, 전반적으로 갈대나 애기부들에 비해 월등하게 나타났다. 특히 초기 생육이 좋았던 줄은 자연적으로 유입돼 발생하는 잡초들에 의한 피해가 거의 없었던 반면 갈대나 애기부들의 경우 다년생 잡초를 포함한 여러 잡초와의 종간 경쟁으로 생육이 다소 부진하였다. 특히 얕은 수심환경과 moss peat를 포함한 혼합 매질 조건에선 식재종들의 생육이 전반적으로 부진하였으며, 그로 인해 잡초들의 생육이 상대적으로 좋았다. 높은 지상부 생산성을 위한 인공습지 조성을 위해선 줄과 같이 생육 환경에 크게 구애받지 않으며 초기 생육이 뛰어난 종의 선발을 통해 자연유입 잡초나 야생동물 등에 의한 피해를 최소화시켜야 할 것이다. 만약 줄이 아닌 갈대나 애기부들과 같은 종을 식재하고자 한다면 온실과 같은 환경에서 일정 수준 이상 생육시킨 뒤 식재함으로써 더욱 경쟁력을 제고시킬 수 있을 것이다. 더불어 높은 지상부 생산성을 위한 인공습지를 지속적으로 유지시키기 위해선 한두 가지 선택지가 아닌 제초와 관련된 최적의 관리방안들을 적시에 활용하는 통합적 잡초 관리 시스템의 적용을 제안하는 바이다.

Chronic health problems has become a major concern and challenge to the health care professionals today. Especially hypertension, one of the leading primary cause of death in Korea, is a typical chronic disease requiring adequate and continuous management. Though these hypertensives need to maintain desirable health practice by themselves for their life time, many previous studies indicated that most of the essential hypertensives have no specific symptoms and thus, reluctant to follow appropriate medical regimens causing the condition further aggravated and complicated. Self-care is an essential factor that keeps chronic patients in control of their health and wellness. Thus this study was conducted to identify the effect of the comprehensive self-regulation program as a nursing intervention on the promotion self-care performance and improvement in physical parameters of hypertensives. For this purpose, a one group quasi-experimental research with pre and post test design was used. The subjects of the study was consisted of thirty persons with mild or moderate essential hypertension from two companies in Cheong-ju city. The whole program was carried out from October, 1993 to February, 1994. The self-regulation program was consisted with group education on hypertension and self-care, self-regulation including the blood pressure self-monitoring and recording, recording of daily self-care activities, and encouraging and reinforcing self-efficacy through verbal persuation and enactive attainment. The subjects were asked to measure their own blood pressure by themselves twice per day and to record blood pressure and the daily self-care performance according to the instructions provided during the whole period of 9 weeks. The instruments used for data collection in this study were as follows : 1) Instruments used for measuring the knowledge about hypertension, multiple health locus of control, and perceived benifits and barriers were adapted from previous studies and modified by author to be fit for the subjects. 2) Self-efficacy scale and self-care performance record were developed by the author. 3) Physiological parameters included systolic / diastolic blood pressure, body weight, level of blood cholesterol, and 24hour ambulatory blood pressure. The post-experimental Cronbach's Alpha as the reliability test of scales were 0.703-0.897, an appropriate level of confidence. The effect of the program was analyzed by experimental stages ; the first week, the fifth week, and the ninth week since the experimental imput began. Data were analyzed by the SPSS PC+ program with paired t-test and t-test, repeated measure ANOVA, and pearson's correlation to de termine the effect of program. The results were as follows : 1) After the self-regulation program, scores on knowledge(t=-2.41, p=.011), perceived self-efficacy (F=5.60, p=.001), self-care performance(F=22.31, p=.0001) were significantly higher than those before the program. 2) After the program, both systolic and diastolic blood pressure were significantly lower than those before the program(F=10.89 -13.11, p=.0001). However in 24hour ambulatory blood pressure, systolic mean pressure was nearly significantly lower, but not in diastolic mean pressure. 3) After the program, the body weight was significant decresed(t=5.53, p=.0001), but the blood cholesterol level was not decreased significantly except in those cases with higher cholesterol level. 4) There were significant relationships between changes in self-care performance and diastolic pressure at 1st week (r=.3389, p=.033) and changes in self-care performance and systolic pressure at 9th week(r=.3651, p=.024). 5) There were significant relationship between perceived self-efficacy and self-care performance at 5th week(r=.5313, p=.001) and 9th week (r=.3026, p=.052). 6) After the program, internal health locus of control and perceived benefits did not show significant change, but perceived barriers was significantly lower than those before the program (t=3.57, p=.0001). From the above results, it can be concluded that 1) The self-regulation program is an effective nursing strategy to promote self-care performance of hypertensives and to lower the blood pressure. Thus this program can be recommended in the management of the hypertensives in workplaces and community settings. 2) The synthesis of Orem's self-care theory and Bandura's self-regulation & self-efficacy theory in this study was proved to enhance explanation and prediction of the change of self-care behavior. Thus the result of the study would contribute in development of the self-care theory and an expansion of practice-theory.

본 연구의 목적은 기후변화에 따른 이산화탄소와 온도의 변화에 따른 콩밭 우점잡초 깨풀의 생장과 주요 4종의 경엽처리 제초제와 4종의 토양처리 제초제에 대한 약효와 콩의 약해를 평가하여 잡초 관리 방안을 마련하는 데 있다. 생장상과 온실상 조건하에서 온도가 증가할수록 깨풀의 초장 및 생체중은 증가하였다. 이산화탄소 농도에 따른 Fv/Fm, ETR, 초장, 엽면적 및 지상부 생체중은 400 ppm보다 800 ppm에서 더 높았다. 깨풀에 대한 경엽처리제 glufosinate 약효의 경우 생장상 조건의 20℃ 및 25℃보다 30℃에서 온실 상조건의 21℃ 및 25℃보다 29℃에서 감소하였다. 반대로 mecoprop의 경우 생장상 조건의 30℃에 비해 20℃에서 온실상 조건의 29℃에 비해 21℃에서 약효가 감소하였다. 경엽처리제 glyphosate의 경우 온실상 조건하에서는 25℃와 29℃에 비해 21℃에서 약효가 감소하였다. Bentazone을 생장상 조건하에서 1/2량 처리하였을 때 25℃와 30℃에 비해 20℃에서 약효가 감소하였다. 그러나 온실상 조건하에서는 21℃와 25℃에 비해 29℃에서 약효가 감소하였다. 깨풀에 대한 토양처리제 경우 생장상과 온실상 조건하에서 metolachlor와 ethalfluraline의 약효는 온도가 상대적으로 높은 조건하에서 약효가 높았다. 그러나 linuron의 경우는 생장상과 온실상의 온도에 상관없이 약효차이가 없었다. Alachlor의 경우 온실상 조건하에서 19℃와 23℃에 비해 27℃에서 약효가 감소하였다. 경엽처리 제초제 4종을 표준량으로 깨풀에 처리하였을 때 이산화탄소농도에 따른 차이는 없었다. 그러나 깨풀에 glyphosate 1/4량 처리하였을 때 이산화탄소 농도가 400 ppm보다 800 ppm일 때 약효는 감소하였다. 반대로 bentazone를 1/4량 처리하였을 때 이산화탄소 농도가 400 ppm보다 800 ppm일 때 약효는 증가하였다. Glufosinate은 처리약량에 상관없이 이산화탄소 농도에 따른 유의적인 차이가 없었다. 토양처리 제초제 ethalfluralin을 1/4량 처리하였을 때는 이산화탄소의 농도가 800 ppm일 때 약효가 더 높았다. 그 외의 제초제의 경우 이산화탄소 농도와 상관없이 깨풀의 약효에는 차이가 없었다. 콩에 토양처리 제초제를 표준량과 표준량의 2배량을 처리하였을 때 온도와 이산화탄소 농도에 따른 약해는 유의적인 차이가 없었다. 따라서 온도와 이산화탄소 농도 증가에 기인하여 일부 제초제에 대한 잡초 약효 차이가 있어 기후변화에 의한 새로운 잡초 관리 방법을 개발해야 할 것으로 판단된다.

This study performed a structural questionnaire survey and non-structural interview of the ladies apparel manufacturers in Daegu on the qualification for the employees, skills required for job performance, job training, automatic manufacturing systems, and the use of computer. The results are as follows. 1. Almost all of the apparel manufacturing systems were Pair System, except one Line System in one company. In terms of outsourcing, most of the manufacturers answered “yes,” and in 1998 the outsourcing process was sewing, but in the year 2002, outsourcing has been increased :12 manufacturers(57.1%) outsourcing most of the processes except patterning, 3(14.3%) outsourcing the finish of sewing. 2. The workforce of 1998 and that of 2002 shows a significant difference(P＜. 01) between office work and management. The number of office workers has decreased from 15 down to 5.3 people. On the other hand, that of the management has slightly increased from 5.3 to 9.2 people. The number of the manual workers has decreased from 32.2 to 28.7 people. And the number of tailoring and patterning workers has slightly decreased, but the number has increased in sewing from 3.7 to 7.0 people. 3. The wage of an employee shows a significant difference between a sewing assistant(P＜. 01) and a production manager(P＜. 05), and the wage of a sewing assistant, in particular, has slightly raised from ￦905,000 to ￦1,054,000. 4. The qualifications required of employees are “cooperative human relations”(30.8％), “diligence,” and “ability for job analysis”(26.9％), and “positive thinking” (15.4％) in 1998, and “ability for job analysis”(38.5％), “cooperative human relations”(34.6％), and “positive thinking” (15.4％) in 2002. The areas for job openings are significantly different(P＜. 01) depending on the year. Job openings in the design section has increased from 1(3.8％) to 16 manufacturers (61.5％), and decreased in tailoring section from 22(84.6％) to 2 manufacturers(7.7％). Job openings in the sewing section have increased form 2(7.7％) to 6 manufacturers (23.1％). In terms of sex of the employees, there is a significant difference(P＜. 001). 19 companies(73.1％) wanted “male” in 1998, but 8 companies(30.8％) answered that they want “female” and 17 companies(65.4％) answered that “it does not matter.” About the educational background, there was a significant difference between the years. The number of the companies that want junior college graduates with an associate degree has increased(15 companies(57.7％). There was a significant difference(P＜. 05) in major of the employee. The number of the companies that want fashion majors has increased from 5(19.2％) to 20(76.9％). 5. In terms of job skills required, there was no significant difference. In 1998, “production skills” (46.2％) and “ability for job analysis” (26.9％) were required, and in 2002, “ability for job analysis” (42.3％) and “emotional skills” (26.9％). 6. In regard to training for job skills, “fashion professional training” has slightly decreased from 65.4％ in 1998 to 46.2％ in 2002, however, “training for job analysis” has slightly increased from 30.8％ in 1998 to 46.2％ in 2002, which indicates the fact that “fashion professional training” and “ability for job analysis” have been emphasized. 7. The number of the manufacturers purchased apparel CAD has increased from 1(3.8％) to 3(11.5％), and the number of the manufacturers that have no plan for purchase has increased from 16(61.5％) in 1998 to 15(57.7％), still taking up a big proportion. 8. About the use of computers in manufacturing, there is a significant difference(P＜. 05). The number of the manufacturers using computer has increased from 5(19.2％) to 15(57.7％) and that of the manufacturers which do not use computers has decreased from 17(57.7％) to 8(30.8％). 9. In the interviews with the owners of the manufacturers, they pointed that schools should give more weight on practical training courses, the invitation of experts in the specific field, complex production systems, training courses for sewing, field trip courses, and furthering specialty education, personality and vocational education.

The main purpose of the study is to identify critical risk factors for development of a family assessment tool to screen high risk family. This study used a conceptual framework of family diagnosis developed by Eui-sook Kim's (1993) and analyzed risk factors to identify the high risk family. As employing a explorative and methodological study design, this study has four stages. 1. In the first stage, 34 family risk factors were identified by doing intensive literature review on conceptual framework of family diagnoses. 2. In the second stage, above risk factors were tested for content validity by consultation with 29 persons in community health nursing, nursing education, family theory, and social work. 3. In the third stage, existing survey data was used for actual application of the identified risk factors. The survey data used for this purpose was previously collected for the community diagnosis in a region of Seoul. At the final stage, through the comparison between high risk and low risk families, initially identified 34 risk factors decreased to 25 risk factors. Among 34 risk factors, six factors did not agree with content of questionnaries sand two factors were not significant in differentiating the high risk family Also, two risk factors showed high correlation between themselves, so only one of those two factors was chosen. As a result, twenty-five risk factors chosen to identify the high risk family are following ; 1. A single parent family due to divorce or death of a partner, or unweded single mother 2. A family with an unrelated household members 3. A family with a working mother with a young child 4. A family with no regular income 5. A family with no rule in family or too strict rules 6. A family with little or no support from other lam-ily members 7. A family with little or no support from friends or relatives 8. A family with little or no time to share with each other 9. A family with family history of hypertension, diabetus, cancer 10. A family with a sick person 11. A family with a mentally ill person 12. A family with a disabled person 13. A family with an alcoholic person 14. A family with a excessive smoker who smokes more than 1 pack / day 15. A family with too much salt intake in their diet. 16. A family with inappropriate management skills for family health 17. A family with high utilization of drug store than hospital to solve the health problems of the family 18. A family with disharmony between husband and wife 19. A family with conflicts among the family members 20. A family with unequal division of labor among family members 21. An authoritative family structure 22. A socially isolated family 23. The location of house is not residential area 24. A family with high risk of accidents 25. The drinking water and sewage systems are not hygienic. The main implication of the results of this study is clinical use. The high risk factors can be used to identify the high risk family effectively and efficiently. The use of high risk factors woule contribute to develop a conceptual framework of family diagnosis in Korea and the list of risk factors need to be revised continuously. Further researches are needed to develop an index of weight of each risk factor and to validate the risk factors.

This study was to analyzed the quality of the meal and the level of nutritional intake in female college students according to the place of residence in female college students. This survey was conducted through questionnaire was given to 359 female students. The subjects were divided into two groups : one group was comprised of those the students who resided in a self-boarding house(SB group, n=245), and the other group comprised of was the student those who resided in the same house with their parents(HWP group, n=114). The mean age of the subjects were 21.6 years old(SB) and 20.6 years old(HWP)(p<0.05). The average height, weight and BMI were 161.8 cm, 57.9 kg, $20.3kg/m^2$ in the SB group and 161.9 cm, 53.4 kg, $20.3kg/m^2$ in HWP group, respectively. The SB group had significantly higher frequency of skipping breakfast and alcohol drinking consumption than the HWP group. There was no significant differences in the mean daily energy intakes between the SB and the HWP groups. However, the plant protein(p<0.01), carbohydrate (p<0.05), vitamin $B_1$(p<0.01), vitamin $B_2$(p<0.05), vitamin C(p<0.01), plant calcium(p<0.01) and potassium(p<0.05) intakes were significantly lower in the SB group were lower than the intakes in the HWP group significantly. And in addition, the cereals(p<0.05) and fruits(p<0.001) intakes in the SB group were significantly lower than the intakes in the HWP group. There was no significant differences in the KDDS and DVS between the two groups, but there was a decreasing trending downward. For that reason, the SB students seemed appeared to have more dietary problems than the HWP students. These results suggest that nutritional education for SB students are is needed in order to supply the lack of management capability on the proper help improve the diet of students living in independently life.

Background: Platinum based concurrent chemo-radiation is the de-facto standard of care in the non-surgical management of locally-advanced head and neck cancer of squamous origin. Three-weekly single agent cisplatin at 100 $mg/m^2$ concurrent with radical radiotherapy has demonstrated consistent improvement in loco-regional control and survival. This improvement is however at the cost of considerable hematologic toxicity and poor overall compliance. The routine use of this regime is improbable in developing countries with limited resources. We therefore aimed to determine the safety and efficacy of an alternative regime of weekly cisplatin and concurrent radiotherapy in such patients. Materials and Methods: January-05 and April-12, 188 patients of locally-advanced head and neck cancer of squamous origin were treated with concurrent weekly-cisplatin at $35mg/m^2$ and conventional radiotherapy 60-66Gy/30-33 fractions/5days per week. Results: Overall, 95% patients received planned doses of RT while 74% completed within the stipulated overall treatment time of <50 days. Eighty-two percent received at-least 5 weekly cycles. Grade-III/IV mucositis was seen in 58%/9% respectively, which resulted in mean weight loss of 9.2% from a pre-treatment mean of 54.5 kg. Grade-III hematologic toxicity-0.5%; grade II nephrotoxicity-2.5% and grade III emesis-3% were also seen. Grade-III/IV subcutaneous toxicity-10%/1% and grade-III/IV xerostomia-10%/0% were observed. Complete responses at the primary site, regional nodes and overall disease were seen in 86%, 89% and 83% patients respectively. The median and 5-years disease-free survival were 26 months and 39.4% respectively, while the median and overall survival were 27 months and 41.8% respectively. Conclusions: Weekly-cisplatin at 35 $mg/m^2$ when delivered concurrently with conventional radical RT (at-least 66y/33 fractions) in locally-advanced head and neck cancer is well tolerated with minimal hematologic and neprologic toxicity and can be routinely delivered on an out-patient basis. It is an effective alternative to the standard 3-weekly cisplatin especially in the context of developing countries.
