본 연구는 정당한 편의가 장애인의 취업 확률 및 직업유지에 영향이 있는 지를 밝히는 데 그 목적이 있다. 분석에는 장애인 고용차별 실태조사 자료가 이용되었다. 분석방법은 취업확률은 로지스틱 회귀분석, 직업유지는 다중 회귀분석 방법을 사용하였다. 분석결과, 취업 확률의 경우 채용 시험 이후 단계의 정당한 편의는 장애인의 취업 확률에 영향이 없는 것으로 나타나는 반면, 채용시험 이전 단계의 정당한 편의는 장애인의 취업 확률에 긍정적인 영향을 나타냈다. 직업 유지 영향의 경우, 모집채용 편의, 사업장 접근성 편의는 고용유지에 영향이 없는 반면, 회사 방침 변경 및 직무조정은 직업유지에 긍정적인 것으로 나타났다. 이러한 결과에 따라 장애인의 취업 가능성을 높이고 직업유지를 증가시키는 방향으로 정당한 편의를 제공할 필요가 있으며, 정책적으로는 정당한 편의에 대한 사업주 지원을 확대할 필요가 있다.

In this study the optimal volume for non-point source control retention is estimated considering spatio-temporal variation of land surface. The 3-parameter mixed exponential probability density function is used to represent the statistical properties of rainfall events, and NRCS-CN method is applied as rainfall-runoff transformation. The catchment drainage area is divided into individual $30m{\times}30m$ cells, and runoff curve number is estimated at each cell. Using the derived probability density function theory, the stormwater probability density function at each cell is derived from the rainfall probability density function and NRCS-CN rainfall-runoff transformation. Considering the antecedent soil moisture condition at each cell and the spatial variation of CN value at the whole catchment drainage area, the ensemble stormwater capture curve is established to estimate the optimal volume for an non-point source control retention. The comparison between spatio-temporally varied land surface and constant land surface is presented as a case study for a urban drainage area.

A series of field tests to estimate the size selectivity of monofilament and multifilament gill net for marbled sole, Pleuronectes yokohamae, were carried out 12 times with five different mesh sizes (86.6, 101.0, 121.2, 137.7 and 151.5mm) in the western sea of Korea from 2007 to 2009. The master selection curve was estimated by the extended Kitahara's method. The total number of catch species was 23 and that of catch was 1,688 in the field tests. Marbled sole of total catch was 1,150 with 68.1 percent. In the monofilament trammel net, the optimum value of total length (TL) per mesh size (m) for 1.0 of retention probability was estimated 0.280 and the values of TL/m were estimated to be 0.187, 0.201, 0.210, 0.218 and 0.226 when the retention probability were 0.1, 0.2, 0.3, 0.4 and 0.5, respectively. In the multifilament trammel net, the optimum value of TL/m for 1.0 of retention probability was estimated 0.307 and the values of TL/m were estimated to be 0.195, 0.211, 0.222, 0.232 and 0.241 when the retention probability were 0.1, 0.2, 0.3, 0.4 and 0.5, respectively.

In the current era of globalization, financial and banking organizations have been facing ever-growing challenges in the global market regarding retention, customer satisfaction, commitment, engagement, proper services, and the belief of their employees. Employees are regarded as an enormous asset for every organization that plays an important role in achieving the vision of the company. The objective of this study is to explore the determinants of bank employee retention and its impact on an organization in the context of Bangladesh. In terms of research purpose, non-probability convenience sampling has been used in this study, and the targeted population was the commercial bank employees of Bangladesh. In terms of data collection, the researchers have used the adopted questionnaires from previous studies. In this study, the total sample size was 180, and a questionnaire was sent to the respondents through e-mails. For analyzing the collected data, SPSS 26.0 version has been used to test the study model and the proposed hypotheses. This study shows that there were four independent variables training and development, organizational culture, job satisfaction, and career development have a positive and significant impact on employee retention. So, the bank management should organize the retention program for the welfare of the employees.

To estimate the mesh selectivity of gillnet for ocellate spot skate (Okamejei kenojei), the field tests were carried out 12 times with six different mesh sizes (121.2mm, 137.7mm, 151.5mm, 168.3mm, 178.2mm, 189.4mm) in the coastal waters of Taean, Chungcheongnamdo of Korea, 2010~2011. In the field tests, the total number of species was 31, and that of catch was 1,410 and the total weight was 618,006g. The number and weight of ocellate spot skate which is main target in this study were 1,004 and 434,592g, respectively. The catch in number of ocellate spot skate occupied about 71.2% in total catch. The others of catch species were marbled sole (8.4%), sea raven (4.4%), japanese swimming crab (4.2%) and flatfish (4.1%) and so on. The range of body disk width (DW) of ocellate spot skates which were caught in this study was 15.2~35cm and the mode was 27~29cm. The estimation equation of mesh selectivity using the extended Kitahara's method was expressed as s $(R)=s(DW/m)={\exp}\{(-0.56R^3-1.80R^2+12.96R-9.99)-4.26\}$. The optimum value of DW/m for 1.0 of retention probability in this estimation equation was estimated 1.899 and DW/m was estimated to be 1.194, 1.314, 1.395, 1.461 and 1.520 when the retention probability were 0.1, 0.2, 0.3, 0.4 and 0.5, respectively. When applied to the retention probability of 0.5, the optimum mesh size was estimated to be 177.0mm on first maturity disk width 26.9cm of ocellate spot skate.

The annual production of silver croaker (Argyrosomus argentatus) in Korean towed fishing gears has been increased in recent five years. In 2017, the annual production of silver croaker in metric ton was increased 99.2% compared to 2013. However, the research for silver croaker has been focused on ecology in Korea. There has not been enough research in terms of fishing gears. Therefore, the research for retention probability for towed gears was conducted on covered codend method from June, 2016 to July, 2018. During the experiments, the total catch of silver croaker was 1,563. The geometry of the experimental trawl gear was controlled by trawl monitoring system; net height was 3.3 m, distance of trawldoors was 59.8 m and distance of wing net was 17.3 m. The selection curve for silver croaker was estimated by a logit model. The analysis was applied with the confidence interval to reduce uncertainty of the estimation. The $l_{50}$ was 13.87 cm and its selection range was 2.71 cm. P-value was estimated at 0.99. The mesh size for silver croaker in towed gears needs to be adjusted by considering its minimum maturity length, stakeholder's interests and fisheries regulations.

본 연구는 요양종결 이후 다시 업무에 복귀한 산재근로자들의 복귀 이후 첫 복귀직장에서의 고용지속기간 및 고용중단에 영향을 미치는 요인을 분석하였다. 이를 위해 산재다빈도 상병인 상 하지골절 및 허리질환으로 치료를 받고 직장에 복귀한 515명의 산재근로자 자료를 분석에 활용하였다. 산재근로자의 고용지속기간을 분석한 결과, 복귀 이후 1개월 이내 직장을 그만둔 경우는 5.65%, 3개월 이내 14.14%, 6개월 이내 23.70%, 12개월 이내 32.81%로 나타나, 재해 이후 직업복귀한 근로자 10명 중 3명은 1년 이내 첫 복귀한 직장을 그만두는 것으로 나타났다. 그리고 산재근로자의 연령이 높을수록, 미혼에 비하여 기혼이, 재해 당시 근속기간이 길수록, 타직복귀에 비하여 원직복귀가, 재해 전후 소득변화가 없는 경우에 비하여 증가한 경우가 재해 이후 첫 복귀직장에서의 고용중단 가능성이 낮았고, 대졸 이상에 비하여 중졸 이하가, 허리질환에 비하여 상 하지골절이 고용중단 가능성이 높은 것으로 나타났다. 이러한 결과를 토대로 하여 산재근로자의 고용지속성을 높이기 위한 정책적 함의를 제시하였다.

Selection procedures of earth retention systems are increasingly complex and directly related to the serviceability of the retaining structure selection systems since significant changes in earth retention technology motivates the review of design, and selection processes of earth retaining structures. Collection and classification of retaining structure selection knowledge are key issues because two expert groups, geotechnical and structural engineers, are mainly involved in the retaining structure selection. The course of natural tendency of expert knowledge are investigated considering the decision factors. The decision factors for selecting retaining structures are divided into four categories: application of the structure, and spatial, behavior, and economic constraints.
