  • An essential part of the development of an autonomous ship is supporting technology that can effectively check and diagnose the operational status of the ship form the shore control center on land. This development has recently occurred in the shipbuilding and shipping industries. In this paper, we present a smart ship solution that operates, as a single system, a data collection platform that gathers ship operation data and a service platform that provides various services. When this smart ship solution was applied to an operating ship, it was determined that a variety of high-quality data could be collected compared to existing ship data collection systems. In addition, it was shown that of the operation data collected, analysis of parameters related to the main engine can be used to determine the overall state by deriving valid results and visualizing patterns. In conclusion, it was suggested that a ship's operation status could be checked more effectively and a comprehensive evaluation could be possible at the shore control center if the results of this study were extended to various ship equipment and analyzed together with the operational environment data.

  • In order to develop a dandelion (Taraxacum officinale) with natural food applications, the effects of dandelion leaves and roots powder content on the physical, textural and sensory properties of sulggidduk were examined. Dandelion powders of leaves and roots at 0, 1, 2 and $3\%$ were added to the dandelion sulgidduk. In the dandelion roots powder in sulgidduk, the color intensity of L values and the values and moisture content decreased however, the sensory color intensity, dandelion flavor and overall acceptability increased with increasing the dandelion powder content. The sensory overall acceptability indicated the dandelion roots powder content at 3% had the highest overall and flavor scores. As the dandelion leaves content was increased, the moisture contents, lightness, adhesiveness and cohesiveness of sulggidduk decreased, while the sensory color intensity, sensory hardness, hardness of texture properties and dandelion flavor increased. The addition at $1\%$ of the dandelion leaves powder content with the dandelion sulggidduk and the addition at $3\%$ of the dandelion roots powder content with the dandelion sulggidduk showed the highest overall acceptability.

  • This study examined all the papers published in the Journal of Occupational Health Nursing from 1991 to May 2000 based on an objective frame of evaluation. The purpose of study is to prospect the trend of occupational nursing research and to provide an optimal direction for future occupational nursing service. The results of total 94 studies were analyzed as follows. 1. The number of papers published in 1991-1992, 1993-1995, 1996-1997 was not significantly increased. However, the number of papers were obviously increased after 1998. 2. In the design of research, survey studies were definitely dominant. But, they are gradually decreasing and experimental studies are increasing. 3. In the fields of research, health problems, health risk factors and health awareness were higher than others. Occupational health nurse's task and job satisfaction were main areas of research until the middle of 1990's. However, after then, not only health problem, risk factor and awareness of health but also health promotion and preventive health behavior are increasing in the research areas. 4. The collaborative researches have gradually increased and the type of author has been varied. The number of researches completed by funds was undertaking only 3 among the total 94. 5. In the research analysis, except for case studies and literature studies, the research subjects have been shifted from the occupational health nurses to the industrial workers, and more diversified. The sample size has been enlarged and the major place of the study is industry. The questionnaire was used in many studies as instrument for data collection and measurement. But, complementary methods of diverse instruments have been increased. The method of data analysis has obviously showed some changes moving from descriptive statistics to inferential and advanced statistics. 6. The ways of nursing intervention have prominently diversified in experimental studies. The contents of case studies were mainly focused on the health management programs and activities in industry. The research concepts and the contents of literature study were also changed progressively in various way. Based on the above findings, conclusions are extended to the following discussion: Since the Korean Academic Society of Occupational Health Nursing was instituted in 1990, the researches of occupational health nursing have shown an acute methodological development in both quantity and quality. However, they were considered still in the lack of research verifying the effects of nursing intervention program. Also, the development of nursing intervention and nursing theory lacked. Therefore, more empirical researches are strongly needed to utilize the field of occupational health nursing in Korea Researchers are also encouraged to exert more efforts to get research funds.

  • Objective: This study was conducted to enable on-line prediction of primal and commercial cut weights in Korean slaughter pigs by AutoFom III, which non-invasively scans pig carcasses early after slaughter using ultrasonic sensors. Methods: A total of 162 Landrace, Yorkshire, and Duroc (LYD) pigs and 154 LYD pigs representing the yearly Korean slaughter distribution were included in the calibration and validation dataset, respectively. Partial least squares (PLS) models were developed for prediction of the weight of deboned shoulder blade, shoulder picnic, belly, loin, and ham. In addition, AutoFom III's ability to predict the weight of the commercial cuts of spare rib, jowl, false lean, back rib, diaphragm, and tenderloin was investigated. Each cut was manually prepared by local butchers and then recorded. Results: The cross-validated prediction accuracy ($R^2cv$) of the calibration models for deboned shoulder blade, shoulder picnic, loin, belly, and ham ranged from 0.77 to 0.86. The $R^2cv$ for tenderloin, spare rib, diaphragm, false lean, jowl, and back rib ranged from 0.34 to 0.62. Because the $R^2cv$ of the latter commercial cuts were less than 0.65, AutoFom III was less accurate for the prediction of those cuts. The root mean squares error of cross validation calibration (RMSECV) model was comparable to the root mean squares error of prediction (RMSEP), although the RMSECV was numerically higher than RMSEP for the deboned shoulder blade and belly. Conclusion: AutoFom III predicts the weight of deboned shoulder blade, shoulder picnic, loin, belly, and ham with high accuracy, and is a suitable process analytical tool for sorting pork primals in Korea. However, AutoFom III's prediction of smaller commercial Korean cuts is less accurate, which may be attributed to the lack of anatomical reference points and the lack of a good correlation between the scanned area of the carcass and those traits.

  • Diagnosis and Prediction of urban industrial structure is a key subject for establishment of sustainable urban development plan. By this time, studies of industry-related urban spatial structure have been concentrated on measurement of space distribution by industry type mainly using data about urban industries or total worker numbers. Now, status of workers become an important issue so this study analyzed qualitative change of urban industrial structure in the view of space using work status classification system. For that, data for work status in 1994 and 2004 were collected in towns and villages, and space analysis units were coincided based on change data between 1994 and 2004. Then, it analyzed spatial distribution pattern of employment through qualitative standard called work status using GIS. The analysis results by work status type of Busan industrial structure in GIS circumstance were as below. First, traditional labor intensive industries met a limit and service and wholesale/retail sale industries went to be poor livelihood. Therefore, Busan's employment rate should be decreased and worker numbers were statistically increased, however, irregular and non-wage workers were suddenly increased. So, it was determined that the quality of employment in Busan area came down. Second, a traditional downtown area has dwindled; on the other hand, employment has been increased in new town or new industrial complex and in the area developed services rather than the manufacturing industry. It is expected that the result of this study may be meaningful as data to prepare for longterm industrial development plan through qualitative evaluation called work status as well as to make behavior pattern of industrial structure which is basis of urban development.

  • Globally, efforts are being made to develop and strengthen a palliative care policy to support a comprehensive healthcare system. Korea has implemented a hospice and palliative care (HPC) policy as part of a cancer policy under the 10 year plan to conquer cancer and a comprehensive measure for national cancer management. A legal ground for the HPC policy was laid by the Cancer Control Act passed in 2003. Currently in the process is legislation of a law on the decision for life-sustaining treatment for HPC and terminally-ill patients. The relevant law has expanded the policy-affected disease group from terminal cancer to cancer, human immunodeficiency virus/acquired immune deficiency syndrome, chronic obstructive pulmonary disease and chronic liver disease/liver cirrhosis. Since 2015, the National Health Insurance (NHI) scheme reimburses for HPC with a combination of the daily fixed sum and the fee for service systems. By the provision type, the HPC is classified into hospitalization, consultation, and home-based treatment. Also in place is the system that designates, evaluates and supports facilities specializing in HPC, and such facilities are funded by the NHI fund and government subsidy. Also needed along with the legal system are consensus reached by people affected by the policy and more realistic fee levels for HPC. The public and private domains should also cooperate to set HPC standards, train professional caregivers, control quality and establish an evaluation system. A stable funding system should be prepared by utilizing the long-term care insurance fund and hospice care fund.
