  • There is a need to develop diverse cultivation species with reference to the favorites and farming experiences of allotment garden participants, in addition to the crops being cultivated in the gardens. In this study, therefore, a survey on the status of cultivation and the demand for herb crops for the garden participants was conducted. Current trend of the programmes related to allotment garden for city dwellers, executed by various relevant organizations was analyzed. A questionnaire was accomplished by adult participants experiencing farming in allotments. Likewise, interview with farm proprietors was conducted. The results showed that the number of crop species cultivated in allotments was about ten species. The purchase of seeds and nursery plants was mainly dependent on the farmland proprietors. The selection of the crops was made by both wife and husband. The status of herb utilization indicated that 5.7% of participants were cultivating or had cultivated herb plants. Sixty-two percent of participants were not cultivating herb plants because they did not know how. The purposes of using herbs were for medicine and beauty (22.0%), for spices (22.0%) and for enjoyment (29.0%). Thirty-four percent (34.0%) of participants were interested or would like to use the herbs in the future for medicine and beauty, 39.0% for spices and 31.7% for enjoyment. It is expected that the demand for herbs would increase. Also, 78.3% of participants had the intension or had taken into consideration to cultivate the herb plants, if the farmland proprietors would provide the plants. And, they had interest in planting, management and post harvest utilization and if a reference material would be provided as well. An approach to plant new crops might be possible to those who have more than four years of farming experience and possess relatively high level of cultivation techniques. In conclusion, the favorable crop cultivation strategy corresponding to the participants' abilities; and rental process were essential for the sustainable operation of allotment gardens and expanded number of participants. Moreover, there is a need to pay attention to the city dwellers who have a lot of farming experiences in allotment gardens to maintain agriculture and rural community. This is so, because they are interested in agriculture and rural community and most of them replied that they had intentions to move to rural areas in the future.

  • 본 논문에서는 1860년대에서 1930년대까지 비농업직을 중심으로 하여 러시아 극동지역의 한인 이주민의 직업에 관하여 고찰한다. 먼저 이주민의 직업선택과 노동시장에서의 위치에 관한 이론들 즉 문화이론, 분절노동시종이론, 인적자본론 및 인종적 특수시장이론 등을 살펴보고 이들 이론이 러시아 극동지역 이주한인의 직업들 중 농업을 제외한 여러 가지 직종에 어떻게 적용되는지를 검토한다. 이러한 과정을 통해서 기존 이론들에서는 이주민의 직업에 관한 공급적 측면과 수요적 측면을 모두 분리하여 고찰하고 있다는 한계성을 지적한다. 이러한 한계성을 극복하기 위하여 본 논문에서는 러시아 극동지역 한인 이주민의 사례를 들어 이주민의 직업에 관한 두 가지 측면을 모두 통합해야 할 필요성을 설명하고 이를 위해 공급적·수요적 측면을 모두 고려할 수 있는 통합적 모델을 제시한 후 이러한 모델에 따라 러시아 극동지역 한인이주민의 직업에 영향을 키친 요인들을 광업, 어업, 자영업종, 서비스직종, 기타 단순 노무직 등으로 나누어 고찰한다. 마지막으로 이주의 통합적 모형에서 공급적 측면에 포함되는 것으로서는 한인의 농업중심적 성격, 이민직전의 조선에서의 사회경제적 모순 및 한인의 자급자족적 성격 등과 수요적 측면에서는 러시아의 이민정책과 러시아 극동의 다양한 지역적 상황이 고려되어야 함을 지적하였다.

  • Background: An important function of the regional public hospital is to satisfy the basic medical needs of the community through the stable provision of high-quality medical services. The purpose of this study was to identify the relevance index (RI) of the regional public hospital and to identify the factors that affect the RI. Methods: Data were obtained from the 2017 regional public hospital operation evaluation report and 2017 medical monitoring report for vulnerable area. RI of the regional public hospital was a dependent variable, and multiple regression analysis was performed with observed variables of medical supply-demand condition, medical supply, and medical supply structure. Direct effects and indirect effects were confirmed by the analysis of structural equation models (SEM) to see if there were mediating effects. Results: The RI was 13.1%, and the average of all percentage refined diagnosis-related group (RDRG) was 29.4%. Factors affecting RI were medical supply-demand conditions, medical supply, and medical supply structure. As a result of multiple regression analysis, RI was higher when high percentage RDRG of the regional public hospital (t=4.117, p<0.05), the size of regional public hospital location (t=-2.554, p<0.05), and the population of regional public hospital location (t =-2.415, p<0.05) were smaller. The results of the SEM analysis show that the higher the medical supply-demand conditions, the more direct effect of decreasing the RI and the indirect effect of decreasing the effect of reduction through the medical supply (direct effect=-1.322, total effect=-0.573, p<0.01). The higher the medical supply structure, the more direct effect on the RI (direct effect=1.047, p<0.05) and the higher the medical supply, the more indirect effect of RI through the medical supply structure (total effect=direct effect=0.619, p<0.05). Conclusion: It has been confirmed that the provision of medical services can affect the RI the regional public hospital which should be considered in carrying out future policies.

The survey was conducted on 766 households, or 4,065 people, from July 1-31, 1975. The findings from the survey are as follows: 1) In terms of age distribution, 28.7% of the sample was from 10-19, the 40-49 age group was the next largest group, and those over 60 made up 7% of the sample. 2. The education distribution is as follows, 30.4% completed primary school, 22.4% had no formal education, 20.6% attended but did not onplete primary school, and 1.8% attended unversities or higher. 3) In terms of occupation, 55.9% were unemployed or family employees, which represents a large dependent population, 30.4% of the workers were employed in farming or fisheries. 4. The marital status is as follows, 58.8% of the women were married, 32.3% unmarried, and 7.5% divorced. 5) The prevalence rate of mouthy illness was 19.7% of 100 infant, 42.8% became fatally ill within the first year of life. This is a very high percentage compared with more developed nations. 6) Of those reportion on illness, 54.6% sought treatment. The rate of treatment was highest in infants at 77.7%. Us age increased, demand for treatment decreased to 43.1% for those in the aldest age group. The oldest age group also had the highest rate of non treatment at 56.8%. 7) The demand for medical care showed that 65.6% utilized drug stores, 20.2% utilized hospitals and clinics, 5.4% used herbdrug-stores and herb clinices, and 3.9% relied upon folk medicine and withch craft. 8) The utilization of medical facilties by sex is as follows, 65.1% of the men and 66.0% of the women used drug stores, and 19.2% of the men and 20.2% of the women used hospitals and clinics. However, more men (3.5%) were hospitalized than women (1.8%) 9) In terms of out-patient care, the largest age group of males was 10-19 (28.2%), and the largest age group of females was 0-9 (30.8%). There was no sex difference in the use of western pharmacies. Menaged 30-39 and women aged 50-59 were the most frequent users of herb clinics. 10) The rate of receiving treatment at drugstore hospitals went towards declining level in the second case of what While increaing much more at herb clinics and folk medicines in the second case than the first one. 11) After primary utilization of hospitals, 32.7%. of the adults aged 20-59 used drug-stores as a secondary source of care, and 12.8% of children and youth under age 20 continued receiving care at hospitals. 12) After primary utilization of drug-stores, 32.5 % of the adults continued to seek care at drug stores and 1.8% used hospitals. 4.2% of those over age 60 utilized folk medcine and witch craft.

  • 이동단말의 사용이 보편화 됨에 따라 통신 서비스의 개인화 및 맞춤화 요구가 증가하고 있다. 개인화 서비스의 궁극적인 목표는 사용자가 임의의 망으로 로밍해 가더라도 당초 가입한 서비스와 유사한 형태로(same look and feel) 서비스를 제공하는 가상 홈 환경의 실현에 있다. 가상 홈 환경에서는 개인의 서비스를 정의하는 서비스 프로파일의 관리가 필수 절차가 된다. 이러한 가상 흠 환경을 구현하기 위한 두 가지 방법은 가입자가 로밍하는 곳에 프로과일을 중복하여 방문망 내에서 서비스론 제공하는 무조건추종중복[Follow-Me Replication Unconditional(FMRU)] 기법과, 홈 망의 서비스시스템으로부터 서비스를 실행하는 중앙집중(Central) 기법으로, 전자는 call-to-mobiligy ratio(CMR)이 높은 가입자에게, 후자는 CMR이 낮은 가입자에게 적합하다. 그러나 해당 가입자가 어떤 경우에나 고정된 CMR을 갖는 것은 아니므로 평균적인 CMR로 위 두 기법을 선택하여 적용하는 것은 성능 저하의 문제가 있다. 본 논문에서는 가상 홈 환경에서 서비스 프로파일 관리를 위한 두 가지 기법을 구체화하고, FMRU를 개선한 요구기반 무조건추종중복[Follow-Me Replication Unconditional on-Demand(FMRUD)]기법을 제시하였다. 또한 가입자의 변화하는 CMR에 따라 자동적으로 두 기법을 선택하도록 하는 적응적 추종 중복[Adaptive Follow-Me Replication(AFMR)]기법을 제안하였으며 이들을 비교하였다. 반응 수식을 통한 성능분석 결과 프로파일 크기 관점에서 효율성을 판단하며 CMR 변화를 고려하는 AFMR이 더욱 높은성능을 가짐을 알 수 있다.

  • The effect and interaction of Ca and B on exopolysaccharide (EPS) synthesis in the diazotrophically growing cyanobacterium. Nostoc spongiaeforme, was investigated. The absence of B inhibited EPS synthesis 1.56-fold ($16\mu\textrm{g}$ glucose equivalent/mg dry weight, 16 d) over the control cells ($25\mu\textrm{g}$ glucose equivalent) grown in medium containing 0.5 mM Ca and $8{\mu}{\textrm}{m}$ B. When B concentration was raised to $40{\mu}{\textrm}{m}$, EPS production was stimulated 1.8-fold. Reduction of Ca concentraion to one-half (0.25 mM) resulted in increased B demand (16$\muM$) by the cells for EPS production at par with the normal sets. However, without Ca, EPS production also increased as B increased. Addition of B to a Ca-free medium stimulated cyanobacterial diazotrophic growth as well as synthesis of Chl a and phycocyanin (0-8 d). The data suggest B-dependent diazotrophic growth during Ca-deficiency and point to and important interactive role of Ca and B in regulation of cyanobacterial EPS synthesis.

  • Remanufacturing is a process of recovering end-of-life products into serviceable parts for producing new products. Due to the limited supply of recovery cores to remanufacture, a remanufacturing firm also needs to produce or procure new parts for fulfilling the demand. This paper is targeted for solving the problem of determining the optimal amount of newly produced and remanufacturing parts, which is called production and remanufacturing planning (PRP) problem, under uncertain supply of recovery cores. The new production mitigates the risk of insufficient core supply while it takes more costs than the remanufacturing. The PRP model in this paper also considers disassemble-to-order (DTO) environment, in which multiple kinds of parts are remanufactured from multiple products on order of the parts. Whereas existing studies presents only heuristic solutions for DTO remanufacturing, this paper provides an exact solution for this problem and analytical sensitivity of the involved cost parameters, adopting multi-dimensional newsvendor modeling and stochastic linear programming techniques. The result shows that production and remanufacturing plans for multiple products are mutually dependent, and a change of cost parameters involved in only one part is propagated to all other parts.

  • The demand of elderly care facilities due to aging population has been increased and the trend of developed countries implies the necessity of innovate approach for elderly care in Korea. The purpose of this research is to evaluate the flexible elderly housing alternative which has been introduced showing adaptability and small scale. This elderly housing alternative was designed to fulfill the condition of residential facilities for various aging phases from the independent elderly to dependent elderly. The workshop method was used for pre-evaluation of the flexible elderly housing alternative from the viewpoint of administrators, care givers and the elderly. The pre-evaluation is to estimate the facility before finalizing the design so that it facilitates more effective and suitable plan by reducing the trial and error beforehand, unlike the post-evaluation. Major responses of plans were positive and the needs for improvement about some concerns were revealed. Thus, relevant aspects of architectural drawings were amended according to workshop participants' needs and features that require to be reflected during further planning procedures were also improved. The result of this research will develop the flexible elderly housing alternative and contribute to foster environment for the elderly as well.

  • This review focuses on modulation of growth hormone (GH) and its downstream actions on periparturient dairy cows undergoing physiological and metabolic adaptations. During the periparturient period, cows experience a negative energy balance implicating that the feed intake does not meet the total energy demand for the onset of lactation. To regulate this metabolic condition, key hormones of somatotropic axis such as GH, IGF-I and insulin must coordinate adaptations required for the preservation of metabolic homeostasis. The hepatic GHR1A transcript and GHR protein are reduced at parturition, but recovers on postpartum. However, plasma IGF-I concentration remains low even though hepatic abundance of the GHR and IGF-I mRNA return to pre-calving value. This might be caused by alternation in IGFBPs and ALS genes, which consequently affect the plasma IGF-I stability. Plasma insulin level declines in a parallel manner with the decrease in plasma IGF-I after parturition. Increased GH stimulates the lipolytic effects and hepatic glucose synthesis to meet the energy requirement for mammary lactose synthesis, suggesting that GH antagonizes insulin-dependent glucose uptake and attenuates insulin action to decrease gluconeogenesis.

  • About 83% of the total population of Lao PDR lives in rural areas. People living near forest are highly dependent on the forest resources closed to their villages. Especially non-timber forest products (NTFPs) provide a wide range of subsistence needs and are the main source of their cash income. They also make a significant contribution to the country economy. The annual export value of NTFPs is considerably high. 708 edible NTFP species (238 edible plants and 470 animals) have been recorded so far, and about 400 plants have been reported and used as medicinal plants by Lao people. One hundred NTFP species are considered as commercial forest products. The striking trend in NTFP resources is the decline of some commercial species due to increased demand on them for commercialization, and the loss of forest by rapid population growth. To sustainablely manage the NTFPs resources, a number of new management systems are under development and support in progress by the government.
