Ocean surface waves may be modified by ocean current and their observation may be severely distorted if the observer is on a moving platform with changing speed. Tidal current near a sill varies inversely with the water depth, and results spatially inhomogeneous modulation on the surface waves near the sill. For waves propagating upstream, they will encounter stronger current before reaching the sill, and therefore, they will shorten their wavelength with frequency unchanged, increase its amplitude, and it may break if the wave height is larger than 1/7 of the wavelength. These small scale (${\sim}$ 1 km changes is not suitable for satellite radar observation. Spatial distribution of wave-height spectra S(x, y) can not be acquired from wave gauges that are designed for collecting 2-D wave spectra at fixed locations, nor from satellite radar image which is more suitable for observing long swells. Optical images collected from cameras on-board a ship, over high-ground, or onboard an unmanned auto-piloting vehicle (UAV) may have pixel size that is small enough to resolve decimeter-scale short gravity waves. If diffuse sky light is the only source of lighting and it is uniform in camera-viewing directions, then the image intensity is proportional to the surface reflectance R(x, y) of diffuse light, and R is directly related to the surface slope. The slope spectrum and wave-height spectra S(x, y) may then be derived from R(x, y). The results are compared with the in situ measurement of wave spectra over Keelung Sill from a research vessel. The application of this method is for analysis and interpretation of satellite images on studies of current and wave interaction that often require fine scale information of wave-height spectra S(x, y) that changes dynamically with time and space.
Purpose - Recently, internet access and social network utilization using smart phone are increasing. In such a smart environment, interactive activities such as information generation, information searching and information sending are increasing rapidly on-line environment. Therefore, consumers tend to purchase something according to eWOM and also meet the social consensus online environment. In connectivity society, consumers became accessible and engaged in the opinions of others easily. Many decisions that seem like personal decisions are actually social decisions on online connectivity. This paper seeks to explore factors that can help generate a social decision on purchasing of new products in an online environment. Research design, data, and methodology - The process of collecting a lot of wisdom and making an agreement online is called social decision. The purpose of this paper is to examine empirically the influence of factors such as online ties, online eWOM expectancy and online information behavior on online social decision. In addition, We studied online social decision by analyzing the moderating effect of new product innovation. To understand this structural relationship, research hypotheses and research models were set up and empirical analysis was conducted. In order to verify the hypothesis, 208 questionnaires were collected from the residents of Seoul city/Gyeonggi province. The answered questionnaire verifies reliability and validity using SPSS/AMOS and test hypotheses through path analysis and multiple regression analysis. Results - According to the research results, First, online ties don't have a positive impact on online social decision, Second, online eWOM expectancy have a positive impact on online social decision. Third, online information behaviors have a positive impact on online social decision. The degree of innovation of new products have a moderating effect between Independent variables of three factors and dependent variable of social decision. Conclusions - Social decisions have a positive impact on purchasing decisions about new product. There is a great significance in the fact that the online social influence and online social decision have been studied academically. It is meaningful that we have studied in depth the changing phenomenon of consumer purchase decision process in smart environment. The results of these studies provide academic and practical implications.
Background: This paper aims to demonstrate current health expenditure (CHE) and National Health Accounts of the years 2015 constructed according to the SHA2011, which is a new manual of System of Health Accounts (SHA) that was published jointly by the Organization for Economic Cooperation and Development (OECD), Eurostat, and World Health Organization in 2011. Comparison is made with international trends by collecting and analysing health accounts of OECD member countries. Particularly, financing public-private mix is parsed in depth using SHA data of both HF as financing schemes as well as FS (financing source) as their revenue types. Methods: Data sources such as Health Insurance Review and Assessment Service's publications of both motor insurance and drugs are newly used to construct the 2015 National Health Accounts. In the case of private financing, an estimation of total expenditures for revenues by provider groups is made from the Economic Census data; and the household income and expenditure survey, Korean healthcare panel study, etc. are used to allocate those totals into functional classifications. Results: CHE was 115.2 trillion won in 2015, which accounts for 7.4 percent of Korea's gross domestic product. It was a big increase of 9.3 trillion won, 8.8 percent, from the previous year. Government and compulsory schemes's share (or public share) of 56.4% of the CHE in 2015 was much lower than the OECD average of 72.6%. 'Transfers from government domestic revenue' share of total revenue of HF was 17.8% in Korea, lower than the other contribution-based countries. When it comes to 'compulsory contributory health financing schemes,' 'Transfers from government domestic revenue' share of 14.9% was again much lower compared to Japan (44.7%) and Belgium (34.8%) as contribution-based countries. Conclusion: Considering relatively lower public financing share in the inpatient care as well as overall low public financing share of total CHE, priorities in health insurance coverage need to be repositioned among inpatient care, outpatient care and drugs.
The shear strength of deep-sea core sediments from the nofheast equatorial Pacific was measured in various conditions to ensure precision of results. The comparison items were 1) two different measuring systems (hand-held vane and motorized vane), 2) in different places of on-board immediately after collecting the core samples and on-land laboratories after storing these samples for three months in a cold room, 3) two different core samples from a multiple corer within a sampling station, and 4) four different measuring points (holes) from a core sample. In this experiment, the values of shear strength in deep-sea sediments show significant change with depth which increase toward the bottom of core. Also, the results of two cores recovered at the same station indicate that vertical variation of shear strength is mainly caused by the change of physical properties. They strongly support the fact that the difference of vue syrtem and/or experimental conditions are not major factor in the variation of geotechnical properties.

The purpose of this study was to analyze fashion merchandising process, to apply customer information in merchandising process and to examine customer management strategies of fashion industry in on-line and off-line channel. In depth, face to face interviews with structured questionnaires were conducted with MD and customer managers from selected 4 brands, one from each categories of men's, women's, casual and sports wear. Key findings of the study were as follows: First, they followed fashion merchandising process of 18 steps and collected trend information and sales data were applied to planning, selling/promoting process to plan season concept, design, and promotion activity. Second, commonly applied customer information types in fashion merchandising process were all from indirect information collected from sales data and forecasting companies. However, casual and sports wear conducted consumer monitoring activity f3r collecting customer data directly from customer participation. Third, in off-line channel, customers are segmented by amount of purchase they make in a specific time period and all the categories show high interest in valuable customers. However, only men's and woman's wear conducted promotion activities for valuable customers as a differentiated marketing strategy. In on-line channel, companies were interacting with the customers through internet web site to determine their demands. In conclusion, this study has significance in that it propose the necessity and strategy of differentiated customer management approaching by analyzing and comparing fashion merchandising activity process cases.
This study analyzed in depth the students' health fitness trend characteristics based on the per generation characteristics longitudinal grade level document that was produced by collecting heath fitness measurements of students from all over the country for the purpose of exploring the appropriate wellness management plan. The following conclusion was derived through the collected materials and results according to the research purpose and method. First, it was determined that muscular endurance trends for both boys and girls in their elementary school period were similar for the current generation and the previous one, but as they went through their middle school period their muscular endurance development levels were found to be reduced compared with the previous generation students. Second, there was no difference in the cardiorespiratory endurance trends between the current and the previous generation students, unlike all other physical factors. Third, the boys displayed deteriorated reflex development during their growth period compared with their previous generation counterparts. On the other hand, girls displayed mostly stagnant development once they reached 8th grade level within their generation.
In this research, we constructed a 3D riverbed surveying system that is able to acquire the topographical information of a riverbed in real-time. The system consists of a RTK-GPS receiver and a echo sounder for collecting simultaneously the position and the water depth information of riverbed. A program for data composition and transformation was designed to generate the 3D coordinates by combining data of a GPS receiver and a echo sounder and made GIS database construction easy. We extracted TIN, digital elevation model and cross sectional maps of the riverbed by using GIS software from 3D data constructed through test surveying. It was shown that the accuracy of the result was RMS error of 0.069m when compared with the existing methods which use a total station and staffs. It is expected that the 3D riverbed surveying system wiil be able to be utilized to various surveying for water resources management in rivers, sea, dams, storing reservoirs and so forth.
Stroke is known as a detrimental disease that leaves serious sequelae. The stroke patients suffer from limitations of physical and social activities. The patients try to adapt themselves to the limitations in order to achieve rehabilitation. This study was performed to clarify the lived experience of rehabilitation from the stroke patients. In collecting data for this study, in-depth personal interviews were made by a researcher from February to April in 2001 at rehabilitation clinics and physical therapy centers locate in Iksan city. The methodological approach was van Manen's hermeneutic phenomenological methodology in order to understand the meaning and nature of stroke patients' experiences in rehabilitating their physical limitations. Collected data were analyzed with phenomenological way of study that was develope by van Manen. The 8 patients who agreed to participate in this research were inter viewed by researcher under the private and comfortable environment. Personal interviews were done three or five times per each patients and each interview took 70 to 90 minutes. The statements were analyzed and finally revealed three essential themes : Theme 1 - Desperateness to achieve freedom again Theme 2 - Seizing hope of recovering Theme 3 - Seeking support from family members, relatives and friends Based on these themes, stroke patients' rehabilitation experience are described as following. The stroke patients have strong desire to achieve freedom again in order to escape from social isolation. The stroke patients want to go back to the state of their previous health state. The stroke patients strongly try to do anything for their recovering and also to have positive thinking. In the other hand, they feel pity for themselves through desperation, fear, sorrow, and self-pity. The stroke patients have dissatisfaction about neighbors' rumor and attitude toward themselves. The stroke patients have experiences to rely on neighbors' support seeking a warm word of consolation. This research showed us that van Manen's hermeneutic phenomenological methodology leads us to understand stroke patients' rehabilitation process more comprehensibly. Based on this research, it is suggested that further studies provide a foundation for the development of a rehabilitation theory for Korean stroke patients.
The purpose of this study is to examine the relationships between fathers and children with Internet addiction. To achieve the goal, researchers chose face to face interview methods with 12 children who had been considered'at risk'with Internet addiction. More specifically, examiners conducted individual in-depth interviews with 12 children associated with Internet addiction for 30~40 minutes during four sessions through structured questions and non-structured questions. After collecting data, examiners conducted a categorical analysis based on collected data. Finally, the research results, discovered in this research, were as follows: First, the Internet set up the inter-generational barrier in the relationship between father and child, second, children took an interest in the Internet instead of their busy father, Third, the Internet played the role of a place to escape from the awkwardness with their father, fifth, fathers were not able to control the Internet use of their children. Based on the research results, this study suggests a desirable behavior pattern for fathers which can be conducive to children with Internet addiction and their fathers along with a follow-up study.
In this paper, we propose an accident-prevention smart monitoring system for Haenyeo(Woman diver) using Zigbee module and GPS sensor. This system can collect such information as the diving location, the body temperature, the depth of diving, and the diving time of a Woman diver working under the water and then respond immediately to an accident occurring. The research developed a smart Teawak and smart swimming goggles which can measure the state of a Woman diver and her diving activities. Smart Teawak, the buoy tool while a Woman diver is collecting seafoods under water, is able to receive GPS and transmit the data from smart swimming goggles and Zigbee Module to IHSS(IoT based Haenyeo Safety service Software) server. In addition, IHSS, a responsive web, provides the diving location and the state of a Woman diver on the smart phone. As a result, the system will be useful in the aspects of Woman diver' health care and the safety, furthermore, which will significantly contribute to global marketing of Woman diver with its being designated as a UNESCO intangible cultural asset.
