The objective of this study is to review the role and function of the village health worker in the wake of the recent social changes in Korea. The stud}' also aimed at' elucidating' the characteristics of the village health worker organizations developed through community participation in this country. The study methods employed were: a review of literature and other existing information related to VHW's activities ; the use of Questionnaire and interview with VHW's on their activities in one selected county in 1992. The major findings obtained are as follows: 1. So far the community health care activities have been carried out by medical colleges, foreign aid agencies and religious organizations with a view to improving health care for the population in rural area. 2. The VHWs employed by the local community health services received remuneratiorin cash or in kind. However, presently no remuneration is paid to VHWs employed by the government village health projects. The training for VHWs is organized by County Health Center once a year for 1-2days regardless of pre-employment or refresher. 3. The needs of care for maternal and child health and family planning has been decline due to the decrease of the target population, but on the other hand, the needs of care by VHW for prevention of infectious diseases, health of the aging, management of geriatric diseases, prevention of poisoning of pesticides and environmental sanitation has beer increased. 4. It was felt strongly that the training for VHWs should be strengthened by means of developing a problem-solving oriented educational program in order to improve practical skills of VHWs.

Despite the sharp decline of students in our country it has been a surge in new school needs. First, 88 elementary schools survey results, 80 percent plunge and students, and the school was very serious caused by an empty classroom. Second, Students period leading to utilization peaks were consuming on average 5.7 years. Third, Period average reception rate with more than 90% is 5.7 years, more than 80% is 9.1 years, more than 70% was 12.3 years, 60% or more was 14.6 years, 50% or more is 16.6 years, at least 40% is 18.4, 30 % to 18.9 years, 20% or more was found to take is 20.5 years. Therefore, separated by urban and rural areas, urban areas are re-city redevelopment, renovation areas, separated by the old downtown areas and large-scale land development district, Newtown areas such as the restructuring of the school establishment or enlargement of a building and renovation, before relocation, consolidation the overall review will be made.

Objective : We investigated the actual condition of oriental medical office in a public health center. Methods : We classified patients who visited an oriental medical office iin a public pealth center of Dalseong-gun, Daegu Metropolitan City during recent 3 years by KCPJMAIN(data processing system), according to location, age, time(month, year), sex, disease, insurance, etc. Results : As a local category, the residents in Hyeunpung-Myeon higher than 80% of the patients who visited the public health center. The patients aged over 60 occupied 80% of the patients. The frequency of the treatment was more than 10 in those patients aged over 60. The number of the patients was the highest in May when there was a change for the past 36months, whereafter the number has sustained decline for 3-5 months and repeated decreasing. As a gender category, the female inpatients were 10732(82%). This statistics shows that these musculoskeletal system disease occupied large part in them. As a heath insurance category, the patients who were insured by health care were 12454(96.30%). Conclusion : It should need to enable the rural residents who have difficulty benefitting from medical service to reach the service by making their access to the oriental medical office in public health center easier. Most of all, the support from both government and municipality should be urged to accomplish it. plus, it should be included not only boosting doctors' reliance but also improving the capability and services of doctors in public heath center. In conclusion, the treatment service in public health center should be diversified beyond musculoskeletal system disease and the identity transform of public health center should be needed to appeal to young generation.

As post-harvest processes of onions are carried by a 20 kg-net package which results in high-cost and low-efficiency, especially, the insufficient drying and physical damage of onions after harvesting leads to a huge second loss in storage, we had developed a low-cost, high-efficiency post-harvest bulk handling machinery system by collecting onions on a farm using ton-bags, drying with forced air circulation, and sorting/packaging. The post-harvest bulk handling machinery system consisted of 6 devices, and this study designed an automatic feed hopper with a feeding rate control device, an inclined belt conveyor with a two-step chute, and an automatic pallet unloading device for feeding onions into the sorting/packing line. This study also analyzed the performance and control of the total system. The device had 1-ton handling capacity, but the operational condition was set to increase the capacity. The three-step filling method of pallet by the velocity control of the inclined belt conveyor was applied in the post-harvest bulk handling machinery system for the prevention of physical damage. If one worker was set to operate the total system, the time required to complete one palletized load was approximately 5 minutes and 5 seconds. The calculated daily handling capacity was approximately 94 tons, when the daily actual working time was 8 hours. When the developed system was applied to the managerial size of 2,000 ton, the processing cost per ton of the system was decreased by 19.5%, compared with the existing 20 kg-net package-based handling. The developed post-harvest bulk handling machinery system would be a good substitute for the rapid decline and aging of rural labor.

Sildenafil citrate (SIL) a phosphodiesterase 5 inhibitor (PDE5I) has been used for long time as a first line oral drug for erectile dysfunction. Though it has beneficial effects on erectile organ it also has some adverse effects in other cells and/or tissues related to reproductive system when exposed to longer duration. The objective of the present study is to evaluate the long term effect of SIL on sperm parameters in Wistar albino rat. The animals are divided into two groups, for group I - rats were treated with saline (vehicle alone) and group - II oral administration of 5 mg/kg b.w. of SIL was administrated orally once in a day for 120 days. At the end of the trial period animals were sacrificed and epididymal sperm were subjected to various analysis. Results showed significant reduction in sperm count, motility, viability and morphologically intact sperm in long term PDE5I exposed animals when compared to control. Acrosomal status and fertility test also showed significant reduction in long term PDE5I exposed animals. The present study clearly indicated that long term SIL has shown to induce alteration in sperm quality and quantity, leading to decline in fertility rate. Indicate that SIL impinge on spermatogenesis as well as epididymal function. Understanding the molecular down-stream events involved in long-term exposure to PDE5 inhibitor can be valuable to supervise on related infertility issues and to suggest corrective measures.

Korean society became an 'aging society' in 2000 years with a population of 65 years and over occupying $7.2\%$ of the whole population. And we expect that a population of 65 years and over will occupy $14.4\%$ in 2019 years, so Korean society will enter into an 'aged society' Older adults can't react correctly and rapidly to the disaster due to the decline of the physical function, therefore victims of older adults due to the disaster will increase as much as aging proceeds. For reducing sacrifices of older adults due to the disaster, 1 suggest that the propulsion of the disaster service policy for disaster week people like older adults, the policy of minimizing casualties due to fires, reinforcement of fire resources and enlargement of disaster services in rural communities, offering information about disaster services and reinforcement of functions of public relations, making new connection systems (e.g. educating welfare and post officials as volunteer fire officials), supplement of fire fighters, and the policy of lightening fire equipments.

This study analyze the impact of omija(maximowiczia chinensis) market by Korea-China FTA and review the change of mid and long term supply-demand from 2014 to 2018. A scenario is also imported to simulate and measure the impacts of the Korea-China FTA. The scenario is that tariff rates for Chinese product(omija) will be zero after 5 years from 2014. A partial equilibrium model of Omija is specified to forecast mid and long term supply-demand and prices. Equations in the model were estimated by using econometric techniques. The results based on scenario are compared with the results by the baseline case(maintenance of current situation). Our study show that when the tariff rates for Chinese product(Omija) will be zero after 5 years from 2014, the cultivated area of Omija is forecasted to decline until 3,370ha in 2018, and the consumption is forecasted to increase up to 12,040.8MT in 2018, and also total revenue of about 9.8 billion korean won will be decreased during 5 years(2014-2018).

In this study, we examined the hepatic anti-steatosis activity of carnosic acid (CA), a phenolic compound of rosemary (Rosmarinus officinalis) leaves, as well as its possible mechanism of action, in a high-fat diet (HFD)-fed mice model. Mice were fed a HFD, or a HFD supplemented with 0.01% (w/w) CA or 0.02% (w/w) CA, for a period of 12 weeks, after which changes in body weight, blood lipid profiles, and fatty acid mechanism markers were evaluated. The 0.02% (w/w) CA diet resulted in a marked decline in steatosis grade, as well as in homeostasis model assessment of insulin resistance (HOMA-IR) index values, intraperitoneal glucose tolerance test (IGTT) results, body weight gain, liver weight, and blood lipid levels (P < 0.05). The expression level of hepatic lipogenic genes, such as sterol regulating element binding protein-1c (SREBP-1c), liver-fatty acid binding protein (L-FABP), stearoyl-CoA desaturase 1 (SCD1), and fatty acid synthase (FAS), was significantly lower in mice fed 0.01% (w/w) CA and 0.02% (w/w) CA diets than that in the HFD group; on the other hand, the expression level of ${\beta}$-oxidation-related genes, such as peroxisome proliferator-activated receptor ${\alpha}$ (PPAR-${\alpha}$), carnitine palmitoyltransferase 1 (CPT-1), and acyl-CoA oxidase (ACO), was higher in mice fed a 0.02% (w/w) CA diet, than that in the HFD group (P < 0.05). In addition, the hepatic content of palmitic acid (C16:0), palmitoleic acid (C16:1), and oleic acid (C18:1) was significantly lower in mice fed the 0.02% (w/w) CA diet than that in the HFD group (P < 0.05). These results suggest that orally administered CA suppressed HFD-induced hepatic steatosis and fatty liver-related metabolic disorders through decrease of de novo lipogenesis and fatty acid elongation and increase of fatty acid ${\beta}$-oxidation in mice.

In this study, we defined abandoned vacant housing, as well as analyzed where and how the vacancies occurred. The temporal range of this study is 2005 and 2010, while the spatial range is nationwide. The minimum unit of space for the analysis is city district. First, we suggested that in the rural areas, it is necessary to manage an aged detached housing, while in the urban areas, it is necessary to manage aged apartments in order to prevent a large amount of old apartment buildings from becoming an abandoned vacant houses. Second, we proposed to select and manage the priority area in the empty area management. Finally, in the areas where other vacant houses are populated, the abandoned housing problem should be discussed with different measures from a long-term point of view in terms of population movement, population decline, and aging population.

With the low birth rate and the inner city decline, the number of small schools is expected to increase. In this trend, the Ministry of Education has consistently used the number of students as a standard for the merger and abolition of schools since 1982, but it seems that has generated a vicious circle of education in rural areas and also it did not reflect realistic requirements and changes in the times although it is efficiency of local education finances. With the number of students constantly decreasing, it has a high probability to make villages without schools in urban areas if decisions are made by the number of students. In this sense, it is suggested that regional contexts and socioeconomic environment should be taken into account rather than to conduct the merger and abolition of small schools with economic logic. It is necessary to change the direction of improving the quality of education through the operation of small schools for coexistence of schools and villages and a cultivating the manpower needed in the 21st century knowledge information society and the 4th industrial revolution era. Therefore, we tried to find tasks for expanding small schools of the local community and developing small schools suitable for future social change.
