We have analyzed sea surface temperature and salinity data collected in the western Pacific Ocean by using an automated Thermosalinograph (TSG) installed on the RV Onnuri during May - June of 2001. The TSG data exhibit characteristics of water masses distributed in the near surface layer of the cruise area very well. Especially, they reveal the diurnal surface temperature cycle and the effect of rainfall on temperature and salinity in the equatorial region, showing the effectiveness of the use of TSG. Problems to be improved for the better TSG operation are the method of water sampling and calibration of TSG sensors. Installation of a pressure gauge in the TSG system and periodical sensor calibration are strongly recommended to ensure reliability of data.

Geophysical survey has been conducted on the continental margin off the South Shetland Islands aboard R/V Onnuri of KORDI in 1992/1993. About 800-line km of 96-channel reflection data have been acquired. On the seismic section, BSR with strong reflectivity and negative polarity has been found at 700 ms below the sea bottom. BSR is considered as the base of gas hydrates and AVO analysis was performed to study physical properties along BSR. True amplitude recovery and surface consistence amplitude were applied to seismic data and angle gathers were obtained. AVO gradient and AVO intercept are calculated on every CDP gather. Section of AVO intercept show strong reflectivity and negative polarity on BSRs and stronger continuity of BSR than stacked section. Cross plot of intercept-gradient indicates that the lower layer below BSR is filled with free gas.

This study aimed to provide insight into methods for activating management of traditional markets by understanding differences in merchant perception according to whether or not the merchant has participated in management activation education. Analysis of merchants' levels of perception of market activation found that educated merchants had a higher perception of pre-post modernization satisfaction, promotion of traditional market revitalization projects, and post-support changes in sales. In a co-marketing context, educated merchants showed significant differences in onnuri gift certificates, bargain sales, festivals and events, and advertisement promotions. With regards to perception of management performances, educated merchants showed statistically significant higher responses for items such as satisfaction with the current vendor, increased sales, and increased customer awareness. The results in this study may be incorporated into the policy-making processes of the government or local governments in order to revitalize traditional markets, and merchant education for activation of management is deemed to be continuously necessary.

Purpose: This study was conducted to understand the client relationship experience of the physical therapists working at elderly care facilities and to lay the foundation for finding the identity of physical therapists. Methods: In-depth interviews were conducted on eight incumbent physical therapists who had experienced working in elderly care facilities for at least one year. Data collection was conducted between June and September 2017, and the interview took an hour to an hour and a half to complete. After an in-depth interview, it was arranged as a file and analyzed according to the four steps of the phenomenological research method of the Giorgi. Results: Data were collected and analyzed; 19 categories, 6 themes and 5 domains were derived. Six themes were presented according to the 5 domains; the subject of relationships included 'diversity elderly'; context of relationships included 'the world of elderly nursing homes I did not know'; influence of relationships included 'the physical therapist is heartbroken because of the tormenting elderly'; condition of relationships included 'a reality that is tied to work'; aspects of relationships included 'how to reestablishing relationships with the elderly' and 'recognized and identified as a physical therapist'. Conclusion: This study shows that physical therapists working in elderly care facilities generally tend to fulfill their responsibilities and interact with clients; we found that identity of physical therapists was primarily defined by relationship experiences with patients.

The underwater positioning system is important in interpreting data that are acquired from towing vehicles such as the deep-sea camera (DSC) system. Currently, several acoustic positioning systems such as long baseline (LBL), short baseline (SBL), and ultra short baseline (USBL), are used for underwater positioning. The accurate position of DSC, however, could not be determined in a R/V Onnuri unequipped with any of these underwater positioning systems. As an alternative, the DSC position was estimated based on the topography of towing track and cable length in the cruises before 1999. The great uncertainties, however, were found in the areas of flat bottom topography. In the 2003 and 2004 cruises these uncertainties were reduced by calculating the position of DSC with the cable length and seafloor depth below the vessel. The Japanese cruises for Mn-nodule used a similar estimation method for the DSC positioning system with a CTD sensor. Although the latter can provide better information for the position of DSC, the USBL underwater positioning system is strongly recommended for establishing better positioning of DSC and other towing devices.

This study aims to analyze the effects of job satisfaction on turnover intention among the nurses in geriatric hospitals. In terms of study methods, this study developed structured questionnaires, and distributed them to nurses working in 11 geriatric hospitals in metropolitan area. A total of 418 questionnaires (response rate: 87.0%) were used for final analysis. We conducted multiple regression analyses to analyze the influence of job satisfaction on turnover intention, adjusting for the characteristics of the research subjects. The results of this study are as follows. First, both job satisfaction and turnover intention were statistically significantly related to individual and hospital characteristics. Second, turnover intention was lower in older age group, and higher in smaller hospitals. As job satisfaction increases, turnover intention decreases. Third, the results of the regression analysis adjusting for subject's characteristics and job satisfaction's sub-categories show that the turnover intention is lower in nurses who are older, day worker, and work in bigger hospitals. Fourth, the result of subgroup analysis by hospital volume show that both of two groups are influenced by hospital ownership and satisfaction about compensation. In addition, professionalism had a significant effect on decreasing turnover intention in smaller hospitals. However, there was no statistically significant relationship between job satisfaction's sub-categories and turnover intention in larger hospitals. The results of this study confirms that job satisfaction lowers turnover intention among nurses in geriatric hospitals. It is suggested that the administrators of those hospitals continue to monitor critical factors associated with job satisfaction, and thus, reduce turnover intention, which helps improve quality of services.

The Ayu Trough, located in the southern end of the Philippine Sea, represents a divergent boundary between the Philippine Sea and the Caroline Plates. A detailed geophysical survey was carried out in the Ayu Trough by R/V Onnuri. Topographically, the Ayu Trough resembles an slow spreading ridge. The trough can be divided into three sections: the south $(0^{\circ}-1^{\circ}30'N),\;middle\;(1^{\circ}30'-4^{\circ}N)$, and north $(4^{\circ}-6^{\circ}30'N)$. The seafloor in the middle section is characterized by features asymmetric with respect to the axis. These features were probably produced by NW-SE and NNW-SSE extensions and seem to support the argument that the opening of the Ayu Trough occurred in an oblique fashion. Farther south, a long transform fault but with a short offset defines the boundary between middle and southern sections. The axial depth increases a stepwise to the south of $1^{\circ}30'N$. A clear difference can be seen between the southern and middle sections with the latter exhibiting much higher mantle Bouguer anomaly values in the axial region. The anomaly indicates that the axial crust perhaps experienced a much higher degree of extension in the middle than in the southern section. The analyses of magnetic field data reveal that the region beyond 100km exhibits considerable variations, whereas the magnetic anomalies within 100km from the trough axis are very much subdued. This observation suggests that the opening of the Ayu Trough involved an initial stage of rifting of existing volcanic arcs, followed by production of new seafloor.

Characteristics of sleeve-gun arrays installed on the R/V Onnuri were analyzed and compared with survey data. In the case of cluster array, the beam width in the frequency range up to 814Hz is constant as $179.5^{\circ}$, and rapidly narrows in the frequency range of 814-1631Hz. However, in the case of long and wide arrays, as the frequency increases, the beamwidth decreases. The optimal frequency is 69Hz. the main lobe of vertical inclination has its maximum amplitude at phase angle $0^{\circ}$. The optimal frequency of cluster array which produces little side lobe is less than 1631Hz, and those of long and wide arrays are less than 108Hz. As a result, the cluster array produces a good source for high-resolution seismic survey, while the long and wide arrays are suitable for the survey of deep structures. The final high-resolution seismic section with cluster array was compared with that of long and wide arrays.
