To evaluate growth habits, fresh pod yield potential, and possibility of early and late seeding, seeding dates were extended from March 21 to June 20 by PE mulching and non-mulching. Soil temperature, under 5cm from surface, above 15$^{\circ}C$ at 10 a.m. in early seeding reached about March 25 in mulching and April 5 to April 12 in non-mulching. Days to emergence and first flowering were accelerated owing to increasing temperature, as seeding was delayed. Days to emergence according to seeding dates reduced 21 to 8 day in mulching and 33 to 10 day in non-mulching. Days to flowering were ranged from 51 to 26 day in mulching and from 69 to 32 day in non-mulching and differences between mulching and non-mulching on each seeding date had 18 to 4 days. Early seedings till April 21 had 160-170 flowers per plant for 8 weeks, while late seedings from May 21 increased more speedily with 200 flower for 6 weeks. Harvesting of fresh peanut, at 80 days after first flowering, was possible from Aug. 1 to Oct. 7 (133-108 days to harvest) by mulching and from Aug. 19 to Oct. 12 (151 to 114 days) by non-mulching. Yields between mulching and non-mulching in early seeding until April 21 had more difference, but in late seeding after May 21 was higher and showed insignificance. Pod setting periods by early and late seeding were about 3 weeks equally. In late seeding pod setting were almost concentrated for front 15 days. In spite of difference of fresh pod weight between two seeding times, the distributions of average of seed weight showed nearly same tendency.
The purpose of this study is improvement of clinical practice education through examination of satisfaction on clinical practice of physical therapy students and grasping the factor have on effect on satisfaction of clinical practice. The students of the survey were 328 junior college students and 41 University students selected from 8 junior college and 2 University by questionnaire from Oct. 6 to Oct. 26, 1993. The collected data was analyzed by ANOVA, T-test, Multiple range test (Tukey, LSD, Duncan), principal factor analysis according to purpose of study. The results were as follows : The degree of satisfaction according to the item on clinical practice was low as 0.346 of a total 1.0. The degree of satisfaction of instruction(0.40) revealed to be high. Compared with the degree of satisfaction on contents(0.39), practice environment(0.38), satisfaction after practice(0.36), practice hours(0.35), personalrelations(0.33), problem of practice place(0.31), practice evaluation(0.25) revealed to be low. 1. The degree of satisfaction on clinical practice according to education system was lower junior college than University. 2. The degree of satisfaction on clinical practice according to volitional group and another intention group and another intention group was not different. 3. The degree of satisfaction on clinical practice according to the order of merit was not difference A group, B group, C group, but it of D group was low. 4. The degree of satisfaction on clinical practice according to the time of practise, the group that clinical enforce during a session was higher than the group that it enforce during vacation. 5. The degree of satisfaction on clinical practice according to clinical practice place was high in University hospital and general hospital, but was low in hospital and clinic. 6. The degree of satisfaction on clinical practice according to existence or non-existence of a hospital in affiliation was higher existence a hospital in affiliation group than non-existencea hospital in affiliation group. 7.

Objectives : This study was performed to compare consciousness of doctors on cooperative practices of western medicine and traditional Korean medicine, and to provide policy implication for development of cooperative practices. Methods : The structured questionnaires were mailed to 132 doctors working in non-cooperative practicing university hospital and 77 doctors working in cooperative practicing hospitals in Busan metropolitan city. The response rate was 40.2% and 40.3% respectively. This survey was performed from 10 Oct. 2008 to 31 Oct. 2008. Results : The doctors working in general hospital had comparatively negative consciousness on basic concept, value and necessity for cooperative practices and traditional Korean medicine. In regards with disease treatment's effectiveness of cooperative practices, both groups evaluated musculoskeletal and immune disease were more effective than others. There were positive relationships between perception for cost-effectiveness and consciousness on intention to participate cooperative practices(p<0.05). Also doctors who experienced traditional medicine treatment had positive consciousness on cooperative practices(p=0.05). Conclusions : To activate cooperative practices of western medicine and traditional Korean medicine, some efforts should be carried out. These include promoting cooperative education programs in medical schools and traditional Korean medical schools, doing research on cost-effectiveness of cooperative practices, and trying to minimize legal and systemic restrictions for cooperative practices.
Poly(amic acid)(PAA) was prepared by reaction of bicyclo(2,2,2)oct-7-ene-2,3,5,6-tetracarboxylicdianhydride(BTDA) containing double bond for crosslinking and bis[4-(3-aminophenoxy) phenyl] sulfone(BAPS) in N,N-dimethylacetamide(DMAc). The cast film of PAA was heat-treated at different temperatures to create polyimide(PI) films. With increasing thermal crosslinking temperatures from 250 to $350^{\circ}C$, the thermo-mechanical properties, degree of crosslinking, and optical transparency of the cross-linked PI were investigated. The maximum enhancement in the thermo-mechanical properties was observed at a heat treatment condition of $350^{\circ}C$. However, the optical transparency was found to be optimal for $250^{\circ}C$ heat treatment. The degree of crosslinking in NMR was determined to be 85% to 93% with increasing annealing temperature conditions from 250 to $350^{\circ}C$.

The mesothelium is an essential lining for maintaining the normal homeostasis of the closed body cavity and a central component of pathophysiologic processes. The mesothelium has been known as the end target for asbestos which induces asbestos-related lung diseases. Malignant mesothelioma (MM) is a rare and fatal neoplasm predominantly due to asbestos exposure. Adaptation of an advanced and reliable technology is necessary for early detection of MM because it is difficult to diagnose this disease in its early stages. Optical coherence tomography (OCT) provides cross-sectional images of micro-tissue structures with a resolution of $2-10{\mu}m$ that can image the mesothelium with a thickness of ${\sim}100{\mu}m$ and, therefore, enable investigation of early development of MM. The mesothelium is typically located at the pleura and tunica vaginalis of the scrotum. In this study, we developed animal window models in the above two anatomical sites to visualize mesothelial layers within the mesothelium. OCT images at the two locations were also acquired.
In this study, we demonstrated Fourier-domain/swept-source optical coherence tomography (FD/SS-OCT) at a center wavelength of 800 nm for in vivo human retinal imaging. A wavelength-swept source was constructed with a semiconductor optical amplifier, a fiber Fabry-Perot tunable filter, isolators, and a fiber coupler in a ring cavity. Our swept source produced a laser output with a tuning range of 42 nm (779 to 821 nm) and an average power of 3.9 mW. The wavelength-swept speed in this configuration with bidirectionality is 2,000 axial scans per second. In addition, we suggested a modified zero-crossing method to achieve equal sample spacing in the wavenumber (k) domain and to increase the image depth range. FD/SS-OCT has a sensitivity of ~89.7 dB and an axial resolution of 10.4 ${\mu}m$ in air. When a retinal image with 2,000 A-lines/frame is obtained, an acquisition speed of 2.0 fps is achieved.
Purposes: This study was to analyze the effects of organizational culture attributes on organizational effectiveness in newly established general hospital. Method: For this purpose, this study sampled 981 hospital employees working for E hospital opened on Apr. 1, 2019 in Seoul. A total of 981 questionnaires were distributed to them, and 888 ones responded to the survey, which had been conducted from Oct. 17, through Oct. 25, 2019. 793 responses were used for the final analysis. The data collected were processed using the SPSS 19.0K for descriptive statistics, T-test, ANOVA, Pearson's correlation coefficient and regression analysis. Findings: First, The type of organizational culture perceived most by hospital employees was 'hierarchy-oriented' (3.53) followed by 'relation-oriented'(3.33), 'task-oriented'(3.23), 'innovation-oriented'(3.19) and job satisfaction scored 3.13, organizational commitment scored 3.28 on their order. Second, 'Relation-oriented', 'task-oriented' and 'innovation-oriented' was positively correlated with job satisfaction and organizational commitment. hierarchy-oriented' was negatively correlated with job satisfaction and organizational commitment. Third, Factors that significantly influencing on organizational effectiveness in a newly established general hospital were as follows. Factors influencing job satisfaction included 'innovation-oriented', 'relation-oriented' and factors influencing organizational commitment included 'relation-oriented', 'innovation-oriented' and age. Practical Implications: In order to increase the organizational effectiveness of the E-General Hospital, it is necessary to gradually move from a hierarchica l-oriented culture to an innovation-oriented and relationship-oriented culture. Since age also affects organizational commitment, it is necessary to promote stability and growth by promoting the mentor-menti system for new members with a low level of experience and experience.
The purpose of this study was to verify the effectiveness of a life review-narrative group therapy program aimed at increasing ego-integrity in the elderly. The life review-narrative group therapy program was organized according to the tfe course from childhood to old age. The objectives of the program were for the elderly to enhance their self-worth, become aware of their individual self existence, accept aging and death, accept the past and present life, and to make the most of their experiences of overcoming difficulties. The counseling techniques used in the program were mainly reminiscence and re-authoring of the narrative therapy. Thirty-two elderly people aged 60 years and over (16 in each of experimental and control groups) were selected randomly from the Daegu Metropolitan City General Welfare Center for the research. The two groups were identified as equivalent for the study in a pre-test. The program of the experimental group was implemented twice a week for 90 minutes per session over a 6-week period (Sep. 8th - Oct. 14th. 2005). The pre (Sep. 8th 2005), the post (Oct. 14th. 2005) and follow-up (Nov. 14th. 2005) tests were implemented in ordo, to verify the effectiveness of the program. The instruments used in the study were the Ego-Integrity Scale. The data were analyzed using t-test, and Ore-Factor Repeated Measures ANOVA. The findings of the study were as follows. The experimental group evidenced significant effects on enhancing ego-integrity. The result of the post hoc multiple comparisons showed that the effects of the life review-narrative group therapy Program were maintained for one months. Meanwhile the control group did not show any significant change in ego-integrity. Based on these findings, the limitations of the study were discussed, and further research was suggested.
The purpose of this study was to investigate the rate of pregnancy, abortion, delivery and contraceptive use and the relationship between the related factors and the early coitus among Korean teenagers. Method: The subjects of this study were 12,733 teenagers age 13-19 years in 7 major cities and 9 provinces in Korea. Data was collected from 2 Oct., to 28 Oct., 2000 and analyzed by using SPSS 10.0 Program. Results: The results showed pregnancy rate 4.5%, delivery rate 0.5%, abortion rate 0.4%. Adolescent girls who experienced coitus relatively went to vocational school, coeduaction school, night school in the general characteristics (p=0.000). Adolescent girls who experienced coitus tend to go to video room (18.5%), go the singing room (60.7%), the bar (54.8%), petting with the partner during the dates. There were overlapping juvenile delinquencies such as drinking (89.2%), pornography (65.3%), bond inhalation (2.7%), leaving homes (43.7%), smoking (14.5%), cyber sex (70.8%), phone sex (12.9%). Adolescent girls who experienced coitus were more suffering from Wangtta (26.1%) than who had not. They showed significant positive attitudes toward coitus; such as feeling of excitement (6.6%), nature (37.9%), beauty (8.7%). On the other hand, they had more guilty (2.8%) than the inexperienced (p=0.000). The main factors relating to early coitus were 'to confirm love' (46.9%), 'afraid of rejection' (32.2%). They think the benefits of coitus were 'more intimacy with boyfriends' (20.6%), 'satisfaction of curiosity' (16.8%). The losses on coitus were 'worry about pregnancy' (73.7%) and 'unability to refuse sexual contacts' (28.7%) Conclusion: It could be concluded that it is necessary to plan different sex education programs according to general characteristics and delinquency behaviors of teenage girls in Korea.

This study was performed on 302 cases of leptospirosis, tsutsugamushi disease and hemorrhagic fever with renal syndrome(HFRS) which occurred in Chonnam(Do) in 1991 through 1993. The results were as follows : 1. 81.8% of the patients with Leptospirosis and 54.5% of the HFRS patients were men while 61.4% of the patients with tsutsugamushi disease were women. 2. Most patients lived in rural areas(Gun), their educational level was elementary School or lower and their occupations were either farmer or jobless. 3. Peak ages were 40s for leptospirosis(36.4%) and 50s for tsutsugamushi disease and HFRS(32.9% and 36.4% respectively). 4. The high incidence areas of tsutsugamushi disease were northern, eastern and a diagonal line, from northeast to southwest, of the Chonnam area, and these are consistent with a mountainous district. 5. In monthly distribution leptospirosis was higher in Sep. and Oct., and tsutsugamushi disease and HFRS were higher in Oct. and Nov. 6. The first case is occurring and the last case shows up later than in past years.
