Background: An appropriate use of hospital beds can improve productivity of hospital significantly. The authors' previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropriately used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Overall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. These instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.

Recently , it has been popular for family use to sell a watermelon by the piece such as a half or a quarter. Therefore, it has been necessary to detect and sort out hollow or overripened watermelons before they are shipped. Previously, inspection and rejection of hollow or overripened watermelons were carried out by skilled inspectors with their experience and intuition based on the traditional slapping method. In recent years many inspectors have became older and are going to retire. Thus automatic quality measuring devices have to be developed. There are many reports on the measurement of internal quality for watermelons with non-destructive methods. However, there is no online device to detect and measure both hollow and ripeness of watermelons until now. We have developed the model MWA-9002 online device to detect hollow and measuring the ripeness of watermelons by acoustic impulse. The developed of this devices has enables accurate distinction and rejection at the same level of the skilled inspectors, and also has saved labor. Nowadays nine automatic watermelon sorting and packing facilities applied this device have installed in Japan.

In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.

Purpose: This study was to define the care time of elderly in long-term care facilities and to compare and analysis the care time by staff and facility types. Method: The data were collected from 530 elderly over sixty, residing in two long-term care hospitals for dementia, three long-term care hospitals for the elderly and two skilled nursing facilities. Care time for individual residents was measured the total time spent by nurses, aides. Result: The average care time measured by nursing staff was 158.6 minutes a day. The average care time for one resident by nurse was 40.4 minutes, and by aides, 118.2 minutes. The difference of the care time showed statistical significance between long-term care facility types(p<0.001) : average care time for dementia hospital(199.1min) was twice as long as that of skilled nursing facility(94.1min). Conclusion: The results of the study showed that the care time differentiates care time provided to elderly in long-term care facilities in Korea. The study suggests the need to emphasize the importance of standardization of level of staff and service programs by the long-term facilities.

The purpose of this research is to identify the relation between OFDI (Outward Foreign Direct Investment) and wage inequality. In order to analyze various effects of OFDI on wages depending on the types of workers, the research classified laborers into four categories: permanent/skilled worker, permanent/unskilled worker, temporary/skilled worker, and temporary/unskilled worker. With controlling wage-determining factors such as education, labor union, individual fixed-effect, and industry-level effect, this paper examines whether OFDI attributes to the wage inequality among each type of workers. Moreover, this study also analyzes possible effects on wages that could vary according to the different characteristics of investments by classifying OFDI into two groups: OECD and non-OECD. The results reveal that OFDI makes certain differences according to skill-intensity and contract type in terms of influences on wages. It also shows that the effect of OFDI on wages is more subject to contract type than to skill-intensity. The classification of OFDI into OECD and non-OECD proves that effects on wages can vary by characteristics of the subject of investment.

The purpose of this study is to see how career management affects employee retention in professional service businesses (PSOs). The role of knowledge and skills as moderating variables in the relationship between career management and intention to stay is also investigated. A review of the literature on career management, which includes promotion, training, mentorship, starting salary, and the laxity-stringency of organizational entry-exit rules, leads to the hypothesis that career management positively affects employees' intentions to stay. Such a positive impact may differ between knowledgeable and skilled employees and their less knowledgeable and skilled counterparts. Cross-sectional data is obtained from 200 professionals working for various PSOs. Stepwise regression is employed to analyze the data. The research found that career management positively affects the intention to stay. The impact of promotion, training and mentorship on the intention to stay is moderated by knowledge and skills. Conversely, knowledge and skills do not moderate the effect of starting salary and the laxity-stringency of organizational entry-exit on intention to stay. The study's findings imply that by implementing effective career management, talented professionals can be retained. However, the level of knowledge and skills should be carefully considered. These findings offer significant insights into human capital management, particularly in PSOs.

Objective: The purpose of this study was to investigate kinematic differences in back pike somersault in platform diving according to skill level and to apply the findings to improve performance. Method: Korean divers participating in this study were divided into a skilled group (age: $21.6{\pm}4.16y$, height: $1.68{\pm}0.03m$, weight: $62.0{\pm}3.94kg$, career: $12.6{\pm}5.13y$) and a less-skilled group (age: $20.6{\pm}2.7y$, height: $1.72{\pm}0.05m$, weight: $64.8{\pm}6.76kg$, career: $12.2{\pm}2.49y$) and an independent t-test was performed to analyze differences between groups at the moment of takeoff. Results: The two groups showed significant differences in displacement and velocity of center of mass (COM), takeoff angle, hip joint angle, knee joint angular velocity, and hip joint angular velocity at the takeoff (p<.05), and significant differences in displacement of COM, hip joint, and ankle joint during flight (p<.05). Conclusion: For a successful back pike, the COM should rise quickly in the vertical direction and the hip joint angle and angular velocity should increase. To improve performance, the back pike turn should be practiced on the ground before an attempt on a 10-m platform, to stretch the ankle and knee joints and enable quick flexion of the hip joint when turning in flight.
