  • Yellow croacker, Tseudociaena manchurica Jordan et Thompson in the Yellow Sea and East China Sea are subjected to be caught by trawl nets throughout the year. First indices of population size in every period 8re calculated. Considering present status of the yellow croacker fishery and ecology of the fish, mathematical models must have been established in order to determine catchability coefficient, natural m ortali ty, fishing mortality, recrui ting coefficient of the fish ing ground, and dispersion coefficienl from the fishing ground. The results an, summmarized as follows: Catchabil i ty coefficient $(C) = 2. 2628 {\times} 10^{-5}$ Natural mortality (M)=0.3293 Population for lhe first half season(July 1st to the following January 3lst) Initial population = 14, 621 $/\frac{M}{T}$ Recruitment =45, 597 $/\frac{M}{T}$ Natural mortality = 8, 660 $/\frac{M}{T}$ Final population =42, 970 $/\frac{M}{T}$ Population for the latter 1131f scason(February 1st to June 30th) Initial population = 69, 170 $/\frac{M}{T}$ Dispersion =51, 688 $/\frac{M}{T}$ Natural mortality = 6, 082 $/\frac{M}{T}$ Final population = 1, 802 $/\frac{M}{T}$.

  • A total and consecutive 62 patients between 13 and 58 years of age receiving biological prosthetic heart valves at the Korea University Hospital from January 1978 through October 1983 were analyzed. Out of 71 valves replaced, 64 were Carpentier-Edwards valves, 4 were Ionescu-Shiley valves, 2 were Angell-Shiley valves, 1 was Hancock valve. Early mortality within 30 days after operation was noted in 4 cases[6.4%]. There were no cases of valve-related early death. The 58 early survivors were followed-up for a total 387 patient-year over a period of 3 years to 12 years[Mean$\pm$S.D: 6.37$\pm$2.51 years] at the follow-up end of April 1991. During follow-up, seven patients died and late mortality rate was 12%. There were two major late complications: the one is thromboembolism[1.6% /patient-year], the other is primary tissue failure[2.76% /patient-year]. Ten patients underwent re-replacement of 13 tissue valves because of primary tissue failure[nine Carpentier-Edwards, two Ionescu-Shiley, two Angell-Shiley]. There was operative mortality. The probabilities of freedom from primary tissue failure were 95.4% and 75.3% at 5 and 10 years after operation respectively, The actuarial survival rates were 86.2% and 81.8% at 5 and 10 years after initial surgery respectively.

  • This study aims to establish the foundation for a simultaneity research, draw the potential through Bergson's simultaneity, and explore a space with the possibility of a continued change, focusing on the simultaneous process, in which physical mobility and consciousness of space last together. First, this study was focused on understanding Bergson's simultaneity, on the basis of the perspective that space needs to have more active, dynamic mobility. For understanding Bergson's simultaneity, the understanding of Bergson's duration conception, memory and perception was preceded. After that, the characteristics of simultaneity were extracted from the concepts of duration, change, memory and perception and its characteristics, which are connected to space, were analyzed. As a result, the study on simultaneity that was intensively analyzed, based on diverse cases, re-awakened the basis of value or thought, which we must aim at, in space design of the present time. This shows the possibility of another creative form that can be found in spaces of the present time and serves as the foundation to discover an essential and potential value of space in space design. Moreover, the combination of space with science, humanities, art and digital media technology demonstrated once again that there is a good possibility of approaching non-representational space that is pursued today and it is anticipated that using Bergson's simultaneity as a medium for spatial combination in their relationship would help in drawing deeper internal meaning and potential of space.

  • Objectives: Malaria remains a public health concern worldwide, including Indonesia. Purworejo is a district in which endemic of malaria, they have re-setup to entering malaria elimination in 2021. Accordingly, actions must be taken to accelerate and guaranty that the goal will reach based on an understanding of the risk factors for malaria. Thus, we analysed malaria risk factors based on human and housing conditions in Kaligesing, Purworejo, Indonesia. Methods: A case-control study was carried out in Kaligesing subdistrict, Purworejo, Indonesia in July to August 2017. A structured questionnaire and checklist were used to collect data from 96 participants, who consisted of 48 controls and 48 cases. Univariate, bivariate, and multivariate analyses were performed. Results: Bivariate analysis found that education level, the presence of a cattle cage within 100 m of the house, not sleeping under a bednet the previous night, and not closing the doors and windows from 6 p.m. to 5 a.m. were significantly ($p{\leq}0.25$) associated with malaria. Of these factors, only not sleeping under a bednet the previous night and not closing the doors and windows from 6 p.m. to 5 a.m. were significantly associated with malaria. Conclusions: The findings of this study demonstrate that potential risk factor for Malaria should be paid of attention all the time, particularly for an area which is targeting Malaria elimination.

  • Cotton fabric was treated with acrylonitrile in t-butyl alcohol and then aminized by reduction of the resultant cyanoethyl cellulose with LiAIH4, under various temperatures and times. Aminized cotton fabric toras dyed with acid and reactive dye. Dyeability as to temperatures, pH, and color fastness were compared to the amiRe group content of treated cotton fabrics. The results of this study were as follow: 1. D.S of cyanoethyl cellulose has been increased by increasing treating temperatures and times. Maximum D.S of cyanoethyl cellulose was 1.45. By SEM and the tensile strength, the damage of the treated cotton was not observed. 2. Since aminized cotton has greater affinity on acid dye than untreated cotton, dyeability increased with the increase of amino group content, and the lower pH, $60^{\circ}C$. 3. Since amino group in aminized cotton changes surface charge of cotton, dyeability for reactive dye increased by increasing the amino group content. Optimum dyeability was obtained at pH 5-7, $40^{\circ}C$. And dyeability of the amine treated cotton increased with the NaCl conc. 4. Color fastness to washing & light of the amine treated cotton was very low except for the wash fastness of the reactive dye.

  • Purpose: The purpose of this study was to identify community health nursing activities that community health practitioners perceive and their achievements in community by reviewing the community health nursing activities that community health practitioners have done for the last 30 years. Methods: This study was a qualitative study. Thirty one community health practitioners were interviewed using the focus group interview method and data were analyzed using content analysis. Data were collected from April to June in 2011. Results: Community health practitioners perceived themselves as "Community Vitalizers" and 9 categories were identified. They were 'ground to explore new nursing areas', 'assimilation to community', 'ground to establish community diagnosis', 'everyday life health management in the community', 'increased accessibility to medical services for the residents', 'enforced health practices for the residents', 'reinforced self-reliance of community', 'commitment to making a happy village' and 'mental fence of the community.' Conclusion: This study was meaningful in that it explained the unique identity of the community health practitioners and could be used as important basic materials in the process of re-establishment of the roles of Health Offices. Hereafter in-depth study on community competence reinforcement should be made to identify the roles of community health nurses.

  • Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

  • Pregnancies of unmarried women are one of the most serious sex problems because they can negatively affect the lives and development of both unwed mothers and their extramarital children. The number of unwed adolescent mothers is growing recently, extending the seriousness of the problem. This study was conducted to explore the ego-state, life position and family systems that may cause unmarried pregnancy. The data obtained from the structured questionnaire survey of 79 unmarried adolescent mothers and 82 female adolescents were analyzed in terms of frequency and t-test using the SPSS WIN 8.0 program. The results were as follows: 1. Ego-state elements of unmarried adolescent mothers were distributed evenly in general and this falls under the All B(BBBBB) type of ego-gram, just like the adolescents. As for the subject adolescent mothers, CP was the lowest among the 5 egos. 2. As to the life position, the position of "I′m OK, You′re OK"was the highest for both groups, with slight differences. 3. With regard to the family system types sorted by the combination of family cohesion and family adaptability levels, both the adolescent. mothers and adolescents tended to perceive their families as somewhat-balanced or balanced families. 4. While the two groups of adolescent mothers and adolescents showed, on the whole, the same types for all the indicators like above, statistically significant differences were found in more detailed elements.
