This study aims to provide the fundamental data for substantial nursing intervention in the elderly through a comparative appreciation on family support, self-esteem, and health status between the institutionalized elderly people and the home-staying ones. The subjects of this study are the institutionalized 108 elderly people of E and C Public Homes and the home-staying 109 elderly ones of O-Nho In Jeong(a kind of public recreational facilities for the aged) over the age of 65. The instruments for this research are based upon the tool(11 items, 5 points for each) for measuring family support developed by Choi, Young Hee(1984), a self-esteem scale done by Rosenberg (1965), the tools(20 items) for checking the health status of the elderly done by Lee, Young-Ja(1989). The sampling for this study has been carried on from July, 2000 until November, 2000. Questionnaire data were drawn up by personal interviews. The analyses of collected data are based on general characteristics calculated at the rate of 100 percentage to the average, t-test, ANOVA(some difference on a level with p<.05 being subsequently confirmed by DMR) for family support, self-esteem and health status, and Pearson Correlation to verify the hypothetical correlation among the subjects' family support, self-esteem and health status. The results of this study are as follows: 1. The difference between two groups in the light of family support, self-esteem and health status. (1) Family support - The rate of the family support that the institutionalized elderly people perceive turned out to be 22.13, that of the home-staying ones 30.99. (2) Self-esteem - The rate of the self-esteem that the former perceives proved to be 25.59, that of the latter 32.28. (3) Health Status - The rate of the health status that the former perceives turned out to be 39.67, that of the latter 51.60. 2. Family support, self-esteem, health status in terms of demographic characteristic (1) Family support - The group of institutionalized elderly people shows a tendency to be chiefly influenced by the death or life of the spouse and the number of the children; the group of the home staying ones to be chiefly influenced by the educational level (2) Self-esteem - The group of institutionalized elderly people shows a tendency to be chiefly influenced by educational level; the group of the home staying ones to be chiefly influenced by the amount of pocket money, the pocket money provider and the family main supporter. (3) Health Status - The group of institutionalized elderly people shows a tendency to be chiefly influenced by educational level; the group of the home staying ones to be chiefly influenced by age, the death or life of spouse, religion, and the educational level. 3. Correlation among family support, self-esteem, and health status The rate of correlation between family support and health status proved to be the highest (r=.549). After came the rate of correlation between health status and self-esteem, which turned out to be(r=.506). The last came the rate of correlation between family support and self-esteem, which proved to be(r=.406). According to this study, there is a conspicuously close correlation among family support, self-esteem, and health status for the elderly. Thus, it would be indispensable to seek out a variety of nursing intervention ways how the elderly could promote family support, self-esteem, and health status.

This study analyzed and compared characteristic of vegetation structure in Bonghwa mountain, the base Mt. outside urban area, and Hakseoung neighborhood park, Ilsan neighborhood park and Musil neighborhood park, disconnected residual Mt. inside urban area of Wonju. Regarding vegetation of urban forest in Wonju, Quercus mongolica forest and Robinia pseudo-acacia forest were widely distributed in the base Mt. outside urban area. Quercus acutissima forest and Robinia pseudo-acacia forest were widely distributed in the disconnected residual Mt. inside urban area. Forests in both areas were managed as part of forest management campaign. Analysis on importance value of a community classified by DCA and DBH class categorized communities into three groups according to the expected ecological succession. Community B was the one to be maintained as Pinus densiflora community. Community A, D and d were expected to be maintained as Quercus spp. Community. Community C, E, F, e, f and g were classified as exotic plant community. Ecological succession was suspended in both base Mt. outside urban area and disconnected residual Mt. inside urban area. However, importance value of Quercus spp. which appeared in the understory layer and shrub layer and their DBH class showed that the potential for ecological succession of exotic plant community was higher in base Mt. outside urban area than disconnected residual Mt. inside urban area. According to the analysis on number of species and individuals and species diversity, understory and shrub layer were reduced due to Forest Management campaign and plant species which appear at an earlier stage of succession varied as time went by since the campaign began. Species diversity comparison between natural and artificial forest showed no clear difference in both base Mt. outside urban area and disconnected residual Mt. inside urban area due to man-made disruption such as thinning and brush cutting. Six communities in base Mt. outside urban area had 17.76~52.22% of similarity index. Four communities in disconnected residual Mt. inside urban area showed 13.34~37.01% of similarity index, which was lower than base Mt. outside urban area. Among naturalized plants, Tupatorium rugosum and Phytolacca americana appeared more in disconnected residual Mt. inside urban area.

We surveyed bimonthly from April to October 2015 to understand the fish fauna and community structure in Wangpicheon. The collected species during the survey period were 40 species belonging to 15 families. Dominant species by number were Zacco koreanus (31.3%) and Rhynchocypris oxycephalus (14.7%). In biomass, the dominant species were Z. koreanus (29.2%) and Coreoperca herzi (8.6%). Also, nine endemic species (22.5%) including Squalidus multimaculatus and two endangered species (Lethenteron reissneri, Cottus koreanus) were identified. It was identified one introduced species (Oncorhynchus mykiss) from foreign countries for aquaculture. Compared with previous data, nine species were newly identified including L. reissneri, S. gracilis majimae, Pseudobagrus fulvidraco, O. mykiss, Chelon haematocheilus, Siniperca scherzeri, Acanthogobius lactipes, Luciogobius guttatus and Channa argus. Seven species (Rhodeus ocellatus, S. gracilis majimae, Hemibarbus longirostris, Pseudogobio esocinus, Microphysogobio yaluensis, Hemiculter eigenmanni and Cobitis hankugensis) introduced from other native waters in Korea were estimated. According to the analysis of the habitat characteristics of major migratory species (Tribolodon hakonensis, O. keta and Plecoglossus altivelis), O. keta was observed at station 11 and T. hakonensis at station 7, 10 and 11. These fishes have been mainly identified in the downstream. However P. altivelis was widely distributed from station 3 to 11. In the comparison of average standard length of P. altivelis at each station during the same period, populations collected from station 3 and 5 which are mid-upper area of the stream were $125.8{\pm}34.2mm$. Their growth was good compared with those collected from station 8 and 11 (mid-lower area): $80.2{\pm}16.6mm$. This difference in length comes from the artificial structures including weir, thus it is necessary to create a fishway that enables P. altivelis to pass around barriers for free movement and resource management.

Objectives: The purpose of this study is to garner useful information through a comparative analysis of health behaviors and health states between the young-old and old-old elderly in a rural Korean area. Methods: We define the young-old elderly as those 65 to 74 years of age, and the old-old as those over 70. The survey was administered in October and November of 2009 at senior citizen centers in Sangju City, Kyongsangbuk-do, South Korea. The number of subjects surveyed approximated the demographics of the aged population of the administrative district of centers of 24 eup, myeon, and dong. Results: Compared with the young-old elderly, the old-old were vulnerable to population sociological characteristics. While there were many cases of contraction of diseases, only a small percentage of old-old elderly were engaged in regular exercise. In addition, the old-old elderly lagged behind the young-old in terms of physical activity, mental and oral health, hearing, and vision. Conclusions: The vulnerability of the old-old elderly in terms of physical and mental health needs to be acknowledged as various characteristics of the elderly that appears according an age group. A variety of disease prevention and health promotion programs that focus on the health behavior and status of the young-old and old-old elderly need to be developed and put into practice.

Objectives: The purpose of this study was to investigate healthy city project related characteristics to members of the Korea Healthy Cities Partnership(KHCP). Methods: This study analyzed general characteristics of healthy city, characteristics of healthy city(political support, collaboration & citizen participation, healthy city project, infrastructure development, capacity building), self-evaluation of healthy city and etc by self-questionnaires from February to December, 2007, which were distributed to government workers who were in charged in health city project of 23 membership cities of KHCP. Results: The number of urban city was 11(47.8%) and that of rural municipality was 12(52.5%). Public health center was almost in charge of healthy city project(73.9%). As for the characteristics of healthy city, healthy city municipal budget(91.3%), city health profile(91.3%), technical support of cooperative university(82.6%), healthy city regulation(78.3%), citizen participation(78.3%), committee(73.9%), setting approach(69.9%) and healthy city network(69.6%) were good. But intersectoral collaboration(34.8%), long-term healthy city plan(39.1%), administrative policy or campaign promise(43.5%), programs to the vulnerable population(47.8%), department in charge(47.8%) and seminar(47.8%) were not good. Especially, characteristics of healthy city according to the existence of department in charge were significantly different in intersectoral collaboration, citizen participation, setting approach and healthy city network. Conclusions: In spite of rapid expansion in healthy cities, there were great difficulty in political support, collaboration, department in charge and programs of health equity. So we need to go a long way to achieve the vision of healthy cites by its principles and characteristics.

This study is aiming at identifying the foreward and backward lingkage effects of the farm land base development project. Korean Government has continuously carried out farmland base development projets including the integrated agricultural development projects. large and medium scale irrigation projects and the comprehensive development of the four big river basin including tidal land reclamation and estuary dam construction for the all weather farming since 1962. the starting year of the five year economic development plans. Consequently the irrigation rate of paddy fields in Korea reached to 75% in 1998 and to escalate the irrigation rate, the Government had procured heavy investment fund from IBRD. IMF and OECF etc. To cope with the agricultural problems like trade liberalization in accordance with WTO policy, the government has tried to solve such problems as new farmland base development policy, preservation of the farmland and expansion of farmland to meet self-sufficiency of foods in the future. Especially, farmland base development projects have been challanged to environmental and ecological problems in evaluating economic benefits and costs where the value of non-market goods have not been included in those. Up to data, in evaluating benefits and costs of the projects, farmland base development projects have been confined to direct incremental value of farm products and it's related costs. Therefore the projects'efficiency as a decision making criteria has shown the low level of economic efficiencies. In estimating economic efficiencies including Leontiefs input-output analysis of the projects could not be founded in Korea at present. Accordingly this study is aimed at achieving and identifying the following objectives. (1) To identify the problems related to the financial supports of the Government in implementing the proposed projects. (2) To estimated backward and foreward linkage effects of the proposed project from the view point of national economy as a whole. To achieve the objectives, Hwangrak benefited area with reservoir which is located in Seosan-haemi Disticts, Chungnam Province were selected as a case study. The main results of the study are summarized as follows : a. The present value of investment and O & M cost were amounted to 3,510million won and the present value of the value added in related industries was estimated at 5.913million won for the period of economic life of 70 years. b. The total discounted value of farm products in the concerned industries derived by the project was estimated at 10,495million won and the foreward and backward linkage effects of the project were amounted to 6,760 and 5,126million won respectively. c. The total number of employment opportunities derived from the related industries for the period of project life were 3,136 man/year. d. Farmland base development projects were showed that the backward linkage effects estimated by index of the sensitivity dispersion were larger than the forward linkage effect estimated by index of the power of dispersion. On the other hand, the forward linkage effect of rice production value during project life was larger than the backward linkage effect e. The rate of creation of new job opportunity by means of implementing civil engineering works were shown high in itself rather than any other fields. and the linkage effects of production of the project investment were mainly derived from the metal and non-metal fields. f. According to the industrial linkage effect analysis, farmland base development projects were identified economically feasible from the view point of national economy as a whole even though the economic efficiencies of the project was outstandingly decreased owing to delaying construction period and increasing project costs.

On the one hand, the 4th Industrial Revolution provides a positive opportunity to build a new civilization paradigm for mankind. However, on the other hand, due to the 4th Industrial Revolution, artificial intelligence such as 'Goggle Alpha Go' revolutionized and even the human ability was replaced with a 'Silicon Chip' as the opportunity to communicate decreases, the existence of human beings is weakened. And there is a growing concern that the number of violent crimes, such as psychopath, which hunts humans as games, will increase. Moreover, recent international terrorism is being developed in a form similar to 'Psychopathic Violent-Crime' that indiscriminately attacks innocent people. So, the probability that terrorist organizations abuse the positive effects provided by the Fourth Industrial Revolution as means of terrorism is increasing. Therefore, the paradigm of aviation terrorism is expected to change in a way that attacks airport facilities and users rather than aircraft. Because airport facilities are crowded, and psychopathic terrorists are easily accessible. From this point of view, our counter terrorism system of aviation has many weak points in various aspects such as: (1) limitations of counter-terrorism center (2) inefficient on-site command and control system (3) separated organization for aviation security consultation (4) dispersed information collection function in government (5) vulnerable to cyber attack (6) lack of international cooperation network for aviation terrorism. Consequently, it is necessary to improve the domestic counter terrorism system of aviation so as to preemptively respond to the international terrorism. This study propose the following measures to improve the aviation security system by (1) create 'Aviation Special Judicial Police' (2) revise the anti-terrorism law and aviation security law (3) Strengthening the ability respond to terrorism in cyberspace (4) building an international cooperation network for aviation terrorism.

Pseudomembranous colitis, although uncommon, is an important complication of antibiotics that is related to a variety of deleterious effects on the gastrointestinal tract. Rifampicin is one of the 1st line agents in the treatment of tuberculosis and a large number of patients are exposed to its potential adverse effects. We report upon a patient that had diarrhea due to pseudomembranous colitis after receiving antitubeculous medication, and which was probably caused by rifampicin. A 77-year-old man was admitted with diarrhea of three weeks duration. One month previously, he suffered from left pleuritic chest pain and left pleural effusion was noticed at chest X-ray. One week prior to the onset of diarrhea, he was started on empirically isoniazid, rifampicin, ethambutol and pyrazynamide as antituberculous medication. On admission, he complained of diarrhea, left pleuritic chest pain, dyspnea and sputum. On physical examination, breathing sound was decreased in the left lower lung field and bowel sound increased. Pleural biopsy revealed chronic granulomatous inflammation, which was compatible with tuberculosis, Sigmoidoscopy showed whitish to yellowish pseudomembrane with intervening normal mucosa, and his stool was positive for C.difficle toxin. He was diagnosed as pseudomembranous colitis and treated with oral metronidazole and vancomycin. The diarrhea did not recur after reinstitution of the anti-tuberculous medication without rifampicin inpatients with severe diarrhea receiving anti-tuberculous medication, rifampicin induced pseudomembranous colitis should be excluded.

Background : Obstructive sleep apnea syndrome (OSAS) affects systemic blood pressure and cardiac function. The development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac rhythm, suggests that recurrent hypoxia and arousals from sleep may increase a sympathetic nervous system activity. Continuous positive airway pressure (CPAP) therapy has been found to be an effective treatment of OSAS. However, only a few studies have investigated the cardiovascular and sympathetic effects of CPAP therapy. We evaluated influences of nasal CPAP therapy on the cardiovascular system and the sympathetic activity in patients with OSAS. Methods : Thirteen patients with OSAS underwent CPAP therapy and were monitored using polysomnography, blood pressure, heart rate, presence of arrhythmia and the concentration of plasma catecholamines, before and with CPAP therapy. Results: The apnea-hypopnea index (AHI) was significant1y decreased (p<0.01) and the lowest arterial oxygen saturation level was elevated significantly after applying CPAP (p<0.01). Systolic blood pressure tended to decrease after CPAP but without statistical significance. Heart rates during sleep were not significantly different after CPAP. However, the frequency and number of types of arrhythmia decreased and sinus bradytachyarrhythmia disappeared after CPAP. Although there was no significant difference in the level of plasma epinephrine concentration, plasma norepinephrine concentration significantly decreased after CPAP (p<0.05). Conclusion : CPAP therapy decreased the apnea-hypopnea index, hypoxic episodes and plasma norepinephrine concentration. In addition, it decreased the incidence of arrhythmia and tended to decrease the systemic blood pressure. These results indicate that CPAP may play an important role in the prevention of cardiovascular complications in patients with OSAS.

Background : The purpose of this study was to analyze the smoking habits in patients with lung cancer and identify any difference of prevalence according to histologic types of lung cancer. Methods : The data were calculated by total amounts of tar and nicotine inhaled during the whole lifetime according to variation of smoking habit. This study was to investigated any difference of prevalence in lung cancer according to smoking habits. The subjects comprised 150 lung cancer cases and 300 hospital control cases that were matched by age and sex. Smoking habits during the whole lifetime were surveyed by standardized questionnaire. Odds ratios were estimated by unconditional logistic regression analysis. Results : There were 104 male and 34 female lung cancer cases. By histologic type, there were 53 cases of squamous cell carcinoma, 67 of adenocarcinoma and 30 of small cell lung carcinoma. The differences between lung cancer cases and controls according to smoking habits were total duration of smoking, total pack years of smoking and number of cigarettes smoked per day during the previous two years. The odds ratio were higher in Kreyberg I, but not in Kreyberg II, for the longer duration of smoking, the greater total pack years of cigarettes consumed, the more cigarettes smoked per day during the previous two years, the longer duration on non-filter smoking, the earlier life cases who began to smoke, and the higher amounts of calculated total tar and nicotine inhaled over the whole lifetime. When we added grade of inhalation to calculation of amounts of tar and nicotine inhaled over the lifetime, the odds ratios of total inhalation amounts of tar and nicotine were as high as those the without them. Conclusions : This study reconfirmed that smoking habits were strongly associated with lung cancer and that there were different associations between smoking habits and histologic types of lung cancer. In particular, calculations of total tar and nicotine amounts inhaled over the whole lifetime were calculated for the first time in trials from lung cancer epidemiologic studies.
