Long-term care Insurance system for the Elderly was started to respond to the aged society on July 2008 in Korea. So responsibility of the care for the old is being changed from the family to the society. The introduction of that insurance system has brought the growth of demand for care service. To improve the level of quality for care service providers in long-term care, the role of care worker in providers is recognized as important. But welfare system for the care worker seems to be poor. So the Seoul Metropolitan Council is preparing an ordinance for the care worker and the purpose of this study is for the ordinance as well. Questionnaires, interviews, documentary surveys were used to carry out this study. The results of this study are summarized as follows. The job stability is the most important thing for the care worker, so local government has to make efforts to promote the job stability of care worker. A welfare center for care workers is needed for the health for care workers in the local government. And the local government has to supervise service providers more strictly and evaluate them in treatments of care worker.

Smart livestock, which combines information and communication technology (ICT) with livestock, can be said to be an effective solution to existing livestock problems such as productivity improvement, odors, and diseases. So far, it has hardly been universalized; thus, it is necessary to develop automation devices to reduce labor by localizing automation devices to expand the distribution of ICT technology to farms, and to advance precise specifications and health management technology using biometric information. Weighing scales currently being used in livestock farms are to prevent the spread of diseases by diagnosis and preparation for AI and other diseases in advance, using information on the growing weight of duck breeding. However, accurate values cannot be obtained due to poor breeding conditions. In this paper, we developed a separate data transmission system kit for the weighing scale and placed the sensor on top of the weighing scale so that the sensor wire is not affected by pollutants or ducks on the floor. A display function was provided, and a method of receiving and analyzing the serial port data of the weighing device, and then transmitting them to the data collection server was implemented.

The purpose of this study is to suggest the grid search method for selecting an optimal decision tree model. It chooses optimal values for the maximum depth of tree and the minimum number of observations that must exist in a node in order for a split to be attempted. Therefore, the grid search method guarantees building a decision tree model that shows more precise and stable classifying performance. Through empirical analysis using data of job satisfaction of workplace reserve force commanders, we show that the grid search method helps us generate an optimal decision tree model that gives us hints for the improvement direction of labor conditions of Korean workplace reserve force commanders.

It has already been four years as of 2013 since the Departmentalized Classroom System was first introduced following the Korean government's policy. However, no investigation had been made yet on whether the system is properly being managed in practice according to the presented standards, guidelines, and policy direction. Hence, an in-depth investigation and analysis were called for. In line with this, documents were researched, deliberation meetings of experts were held, and the system pilot was tested to develop indices to investigate the state of block-scheduled classes and classes for each student's academic level for the educational classes field. For the school management field, we developed indices to investigate the teachers' organization and their division of labor, administrative officers and work reduction, improvement of teachers' expertise, and the guidance of the students' school life. Based on the indices, we investigated the state of 24 schools, which manage an advanced school system, nationwide. The results showed that the Departmentalized Classroom System has now reached the settling stage, which is beyond the introductory stage, and that it needs to be systematically supplemented for it to be settled in a stable manner.

Recently, it's a trend that the third party outsourcing logistics will be increased a logistics flow from law material to final products. The government also works on promoting logistics company as securing the expertise for strengthen logistics industry and secure competitiveness. Nevertheless, logistics market have been divided by polarization between small logistics company and major company. Also a labor who work for logistics is being caused by worsened working conditions. That is one of results of the survey. Almost 50% of response are they have not been aware of FTA and have not known to need the FTA. Many respondents said that entering the overseas logistics or a new way like FTA will be difficult to take part in. Therefore I suggest several examples in this paper to encourage a vitalization of small logistics company through the multilateral FTA. Now our country needs to make an effort to maximize connections between multilateral FTA and policy effect by signing FTA with many countries and extending Economic territory. This effect can completely cope with the improvement of economic interests, establishing regional integration strategy and change of global supply chain. Therefore, a small business logistics have to make their competitiveness & a new dealing market in the future.

After conducting an investigation of a specific workplace, 372 labor workers, who are employed at a certain domestic petrochemical company valve operating and maintenance processing section, were personally questioned about specific work-related ailments. According to the results, 57% of workers who were working in the petrochemical industry have suffered from pain-related musculoskeletal disorders in, at least, more than 1 body part. Specifically, there are more than 28% of workers suffering from pain in more than two body parts. Among the total work population, 18.8 % of workers are assumed to have a high probability of being diagnosed with musculoskeletal disorder. Also, according to the RULA checklist which evaluates environmental improvement conditions of the workplace, 76.7% of workplaces among the inspected areas have high hazardous work factors that are related to musculoskeletal disorder and needs to be improved upon and observed right away or in the foreseeable future. The prior factor has a high correlation and pain rate which is due to an improper work posture. Originally, this improper work posture is caused mostly by ergonomically incorrect facility design. Furthermore, the structure of the workplace does not consider the worker's individual build.

본 연구는 근로환경이 근로자의 객관적 주관적 보상과 어떠한 관계를 가지는지를 분석함으로써 한국노동시장에 나쁜 근로환경에 대한 보상이 존재하는지를 확인하고 시사점을 제공한다. 근로자가 당면하고 있는 다양한 근로환경과 보상지표를 제공하는 한국근로환경조사(KWCS) 자료를 사용하여 분석한 결과 나쁜 근로환경을 대표하는 위험성은 임금과 유의미한 관계를 보이지 않는 반면 보상만족도와는 부(-)의 관계로 나타난다. 이는 근로자들은 나쁜 근로환경에 대한 보상이 이루어져야 한다고 인식하고 있으나 실제 노동시장에서는 금전적 보상이 이루어지지 않는다는 것을 시사한다. 또한, 노동시장에서 물리적인 위험요인보다 정신적인 위험요인에 대한 기대 보상수준이 높게 나타나며, 이러한 경향은 남성에 비해 여성이 더 크게 나타난다.

Background: This study aimed to establish a strategy to improve the poor working environment and working conditions among long-term healthcare workers in Korea. Methods: A total of 600 questionnaires with which long-term health care workers participated in the targeted base areas of each city and province nationwide were distributed directly and 525 responses were collected and 506 responses were analyzed. Surveys, on-site field visits, and in-depth interviews were also conducted to understand the working environment as well as conditions and establish a strategy for improving the working environment among long-term healthcare workers to understand the demands of working conditions and working conditions. Results: Korean long-term care workers firstly and mostly enumerated their risk factors for ill-health when lifting or moving elderly recipients directly by hand (69.9%), followed by increased physical workload with old beds, tools, and facilities (42.3%) in the workplaces, shortage of manpower (32%), and source of infection (30%). To improve the working environment as well as conditions, Korean long-term care workers considered improving low-wage structures, ergonomic improvements to solve excessive physical loads, and increasing various bonus payments as well as implementing the salary system, positive social awareness, and increasing resting time. Of 506 responses, 92.3% replied that the long-term care insurance system for the elderly should be developed to expand publicization at the national level. Conclusion: This study proposes to improve the low-wage structure of Korean long-term care workers, automation and improvement of facilities, equipment, and tools to eliminate excessive physical loads (beneficiary elderly lifting), and reduction of night labor.

The task of improving a fungal strain is highly time-consuming due to the requirement of a large number of flasks in order to obtain a library with enough diversity. In addition, fermentations (particularly those for fungal cells) are typically performed in high-volume (100-250 ml) shake-flasks. In this study, for large and rapid screening of itaconic acid (IA) high-yielding mutants of Aspergillus terreus, a miniaturized culture method was developed using 12-well and 24-well microtiter plates (MTPs, working volume = 1-2 ml). These miniaturized MTP fermentations were successful, only when highly filamentous forms were induced in the growth cultures. Under these conditions, loose-pelleted morphologies of optimum sizes (less than 0.5 mm in diameter) were casually induced in the MTP production cultures, which turned out to be the prerequisite for the active IA biosynthesis by the mutated strains in the miniaturized fermentations. Another crucial factor for successful MTP fermentation was to supply an optimal amount of dissolved oxygen into the fermentation broth through increasing the agitation speed (240 rpm) and reducing the working volume (1 ml) of each 24-well microtiter plate. Notably, almost identical fermentation physiologies resulted in the 250 ml shake-flasks, as well as in the 12-well and 24-well MTP cultures conducted under the respective optimum conditions, as expressed in terms of the distribution of IA productivity of each mutant. These results reveal that MTP cultures could be considered as viable alternatives for the labor-intensive shake-flask fermentations even for filamentous fungal cells, leading to the rapid development of IA high-yield mutant strains.
