The ocean is a harsh environment and Korea Coast Guard officers often face the threat of death or going missing in the line of duty. In order to promptly identify unknown bodies during mishaps, Korea Coast Guard Research Center has established an identification system using the DNA of its officers. This collected DNA can also be entombed in National Cemeteries when the remains are not recovered. The storage, disposal and quality control of the materials are overseen by the Governing Committee according to the Enforcement Rules for the Human Biological Materials Storage Project for the Identification of Officers Killed or Gone Missing in Action. Approximately 700 bodies are found per year along the Korean coast. An alternative method should be put in place for when identification through fingerprints and teeth are not applicable due to severe decomposition or partial recovery. We believe it would greatly contribute to helping identify the unknown bodies if the storage project could expand its data to include marine industry workers, relevant researchers and those involved in marine leisure activities.

Background : Chunghyul-dan is a combinatorial herbal medicine; previous studies reported it had therapeutic effects for microangiopathy, a major part in the progression of small vessel disease, as well as having anti-hypertensive, anti-hyperlipidemic, anti-apoptotic, anti-oxidative, and anti-inflammatory activities. Therefor, we examined the inhibitory effect of Chunghyul-dan on stroke recurrence in patients with small vessel disease. Methods : We prescribed Chunghyul-dan at 600 mg a day to patients with small vessel disease, and monitored stroke recurrence, drug compliances, and adverse effect for 1 year. We then performed follow-up brain MRI to find new vascular lesions after 1 year of Chunghyul-dan medication. For the subjects lost to follow-up, we assessed their prognosis after 1 year by telephone. Results : There were 73 subjects treated with Chunghyul-dan for 1 year; new vascular events were found in 3. Of the 85 subjects lost to follow-up, fifty four could be contacted, and eight of them had stroke recurrence. One year of Chunghyul-dan medication reduced the odds ratio of stroke recurrence by 75% compared to the subjects lost to follow-up and the rate increased to 88%, when adjusted for other relevant risk factors for stroke recurrence. These reductions were much higher than those of aspirin and other kinds of conventional anti-platelets. There was no adverse effect in any of the study subjects. Conclusions : We suggest Chunghyul-dan could be useful for inhibition of stroke recurrence. Further study with a randomized controlled trial is needed to confirm this suggestion.

Is there my relationship between a port information system and a port type? This paper aims to define its relationship through a study on the port types of advanced countries and their information systems. In terms of port ownership and its governing body, the port type can be divided into 4 types: state-run, public corporation, local government-run, and private ownership. According to the port type, the major activities of ports are different. In the case of a state-run and local government-run port, they put emphasis on the function of administration, but a public corporation and private ownership stress the importance of customer services. The study results of the mutual relationship of a port type and an information system show that the state-run and local government-run ports have a good administration-oriented system, and public corporation and privatized ports have an excellent customer-oriented community system and e-business system. The differences in the information system by port type provide an important suggestion to the improvement of information system of Busan Port Authority. As Busan port has been transformed from a state-run type to a public corporation, a new port information system has to be followed. Accordingly, this study has suggested a three-stage development plan: The first is a mirroring stage of stabilizing the port management, the second is a cooperation stage of enhancing customer services through the establishment of a community system, and the third is an e-business stage of developing a profit system in order to create value added.

Alluviums in the Keum River watershed cover an areal extent of $3,029{\;}\textrm{km}^2$ and contain about 8.1 billion tons of groundwater. However, the waters are severely polluted by nitrate, possibly due to the application of nitrogen fertilizer (>250 N kg/ha) on agricultural land. This paper aims to elucidate the pollution status and behaviors of nitrate in alluvial groundwaters in the Keum River watershed area, based on regional hydrogeochemical study. Most of the collected samples (n = 186) are polluted by nitrate (average = 42.2 mg/L, maximum = 295 mg/L). About 29% of the samples have the nitrate concentrations exceeding Korean Drinking Water Standard (44 mg/L $NO_3$). The distribution of nitrate concentrations in the study area is largely dependant on geochemical environments of alluvial aquifers. In particular, the decrease of redox potential of alluvial groundwaters showed a good correlation with the decreases of nitrate, iron, and manganese concentrations. Thus, the change of redox state in alluvial aquifers, likely reflecting their sedimentary environments, controls both the behavior and fate of nitrogen compounds and their natural attenuation (denitrification) in aquifers. A carbon-rich, silty layer within alluvium strata forms a reducing condition and possesses a buffering capacity on nitrate pollution.

The geography, circulation pattern, and ecology show that the semi-closed seas of Northwest Pacific be managed as one complete system. Ongoing multilateral cooperative efforts relevant to marine environmental protection in the Northwest Pacific area, include the Working Group for the Western Pacific (WESTPAC) established under the auspices of WNESCO's Intergovernmental Oceanographic Commissions, the UNDP/GEF Programme on Prevention and Management of Marine Pollution in East Asian Seas (PEMSEA), the North Pacific Marine Science Organization(PICES), and the United Nations Environment Programme(WNEP)'s Northwest Pacific Action Plan(NOWPAP). The present report firstly describes the current situations on the existing regional cooperative regimes for marine environmental conservation in the Northwest Pacific region, with a special respect to the Northwest Pacific Action Plan(NOWPAP) which was adopted in 1994 by Japan, People's Republic of China, Republic of Korea and Russian Federation. Then, problems of the existing regimes are also discussed, together with the suggestion of the possible solutions, focusing on NOWPAP. Suggestions include: 1) the Northeast Asian countries should understand the importance of legally-binding regional convention, and should build up any legally-binding instrument which can function as a big umbrella for real regional cooperation without prejudice to the rights of the States, 2) At present stage, it will be possible to make a regional convention flexible without prejudice to the sovereign right of the States or territorial issues; 3) taking into account that the region often faces many generic political problems that often inhibit the effective collective actions on environmental issues, the leadership from UNEP or other international organizations is required; 4) strong institutional and financial framework should be made, and 5) multilateral efforts to respond to the new marine environmental threats should be taken at the regional level in order to protect the coastal and marine environments in the Northwest Pacific.

The purpose of this study is to understand the current state of the older people's social exclusion by identifying patterns of the change in social exclusion level through a longitudinal analysis with an aim of exploring the predictors of changes. To this end, this study has adopted the panel data, the English longitudinal Study of Ageing(ELSA). The data of 7631 respondents who aged over 50 were used for the final analysis. The social exclusion of the older people was analyzed into five different sub-dimensions: social relationship; cultural activities; access to health services; financial security; and sense of loneliness. The person-centered approach that focuses on the various patterns of the trajectories of change has used semi-parametric group based model in order to estimate different trajectories among individuals. The data was analyzed using Spss 18.0 and SAS 9.2 proc traj. In results, First, semi-parametric group-based model analysis has shown that the older people are not 'homogeneous' group with similar exclusion level in every individual with same trajectories of change, but can be divided into various categories with diverse intercept and slope. Second, different trajectories in change of exclusion level help to confirm that the older people's social exclusion level increases gradually over time or remains unchanged. Third, this analysis has provided the useful guidelines to identify the high-risk groups of social exclusion. Forth, the variables that make difference in more than three dimensions include gender, age, self-perceived health, physical activity, weekly income, marital status, family relation, and beneficiary status. Implications and further suggestion were discussed.

This study includes services that require six professional guides - health care, exhibition performance, restaurant, shopping, business and daily life - as well as a trip-based tour, along with solving existing problems that may occur on domestic and overseas trips, and proposes services that connect users with proven professional guides. As a result of previous research, the most needed services among overseas travel were air tickets, accommodation, transportation, and guides, but as Korea enters an aging society, professional guide services are expected to increase daily demand. Based on this, the service technology, user scenarios and brand development were presented. This Service Proposal provides users with a personalized guide to knowledge or experience that they have not previously known, providing them with a wealth of experience. In addition, guides can help develop new fields of expertise and help improve professional guides' capabilities. Finally, the platform service is meaningful in that it enables the creation of jobs by enabling everyone to engage in economic activities, as it allows users to provide services through their own capabilities while at the same time being convenient for them.

In this study, we examined the adaptive practices of science teachers in their classrooms and their perspectives on the distinguishing features of these practices within science subjects. Our analysis comprised 339 cases from 128 middle and high school science teachers nationwide, and 199 cases on the characteristics of adaptive practices in science disciplines. The primary findings were as follows: First, the most significant characteristic of adaptive practice in science disciplines pertained to experimental procedures. Within the 'suggestion of additional materials/activities' category, the most frequently cited adaptive practice, teachers incorporated demonstrations to either facilitate student comprehension or enhance motivation. Additionally, 'experimental equipment manipulation or presentation of inquiry skills' emerged as the second most common adaptive practice related to experiments. Notably, over 50% of teacher responses regarding the characteristics of adaptive practices in science pertained to experiment guidance. Second, many adaptive practices involving difficulties experienced by students in learning situations were presented, particularly in areas such as numeracy and literacy. Many cases were related to the basic ability of mathematics used as a tool in science learning and understanding scientific terms in Chinese characters. Third, beyond 'experiment guidance', the characteristic adaptive practices of science subjects were related to 'connections between scientific theory and the real world', 'misconception guidance in science', 'cultivation of scientific thinking', and 'convergence approaches'. Fourth, the cases of adaptive practice presented by the science teachers differed by school level and major; therefore, it is necessary to consider school level or major in future research related to adaptive practice. Fifth, most of the adaptive action items with a small number of cases were adaptive actions executed from a macroscopic perspective, so it is necessary to pay attention to related professionalism. Finally, based on the results of this study, the implications for science education were discussed.

Background : A continuous healthcare quality improvement is needed to provide high quality healthcare service as well as to maintain trust in terms of satisfying the needs of the patients. Recently it also became an essential issue. in hospital management, recognized for it's competitive potentiality among healthcare organization groups. This study was conducted to analyze patient complaints and issues received by the Quality Improvement Department. Its purpose is to improve healthcare qualities within the hospital, as well as establish policies and appropriate strategies in hospital management. Method : From July 1st to September 30th of the year 1999, we analyzed all complaints and issues made by various patients and their families, which were received through 24 hour phone consultation, numerous suggestion boxes, letters and E-mails, The issues were classified into 16 different categories based on a Patient Satisfaction Assessment Tool. All data were segregated according to the departmental frequencies and their contents. To come up with for environmental and patient satisfaction improvement, all complaints or issues were communicated with hospital administrators, medical and nursing staff and employees. Comprehensive customer satisfaction activities including improving phone etiquette were discussed in Customer Satisfaction Team, CQI Team and each Department. All opportunities for improvement were implemented. Feedback actions were discussed. Results : A total of 317 cases were collected. Issues regarding parking and other accommodation facilities were most common complaints that were 14.5% of total. Issues regarding admission rooms (10.7%), admission procedures (10.7%), waiting room environment (8.8%), nurses and nurse assistants (7.6%), physicians (6.6%) and others (23%) followed. Thirteen of 45 departments received more than 8 complaints. The Nursing Department had the most complaint, receiving 9.8% of total complaints. Complaints regarding the Nursing Department were predominantly related to the environment of patient rooms. The Department of Psychiatry for phone etiquette (4.7%), Department of Otolaryngology for the nursing staff's attitude and phone etiquette (4.4%), and the Admission Department followed. As a part of efforts to improve patient satisfaction, a new parking structure was built and reallocation of the parking space was done. Renovation of other accommodation facilities were carried out by hospital administration, Monthly phone call and answering attitude survey was done by QI Department. Based on this survey we made a phone etiquette manual and distributed throughout the hospital. Compare to the last year, Patient Satisfaction Index measured by Korea Productivity Center using National Customer Satisfaction Index was improved 7 points. According to our organization's own study, we confirmed the phone etiquette was improved 11% than last year. Conclusions : Issues related to parking and other accommodation facilities ranked first followed by complaints made regarding the patient care area, the admission and cashier process, and nurses' and doctors' attitude. The Nursing and Psychiatry Departments need improvement regarding phone etiquette. Results were shared and played a vital role in policymaking and strategic planning of the hospital. It is imperative that we keep our database updated by listening to and solving the needs of each patient. The CQI activities can be achieved only by full commitment of the hospital top management supported by related personal.
