After the Japanese Invasion of Korea in 1592, correspondents of Chosun called on Japan twelve times, as a mission, from 1607 to 1811. The suite of Chosun Communication Facilities (correspondents) was composed of nearly 500 people including a senior envoy, a junior envoy, other envoyes, and cooks. After preparing traveling expenses, Sifts, foods, medicinal stuffs, and ginseng, they shipped people and freight in three passenger ships and three freighters. They departed from Pusan for Edo(Tokyo). There were 28 stop-overs on their way to Edo and the banquet was given for them at every stop. The arrangements of the table for each banquet were made up of 753 Seon(tables), 3Jeup(soups) and 15Che(dishes). 753Seon(tables) is Ganban(the table for decoration) and a substantial food reception was composed of 3Jeup(soups) and 15Che(dishes). 753Seon(tables) was called Dadopoong(the food of refreshment) style and this was the standard arrangement of the banquet table in Japan. It was comprised of 3Jeup(soups) and 15Che(dishes). On their way from Edo to Thusima Island, food was afforded to correspondents for later preparation and dining. The banquet that the master of Thusima Island gave was composed of the first and second style banquets. The first one was Chusun style and the second one was Japanese style.

This research is to reveal an aspect of costume culture interchange in the relationship of the early Chosun Dynasty, by considering the imported goods from Japan, of the trading goods derived by the trade diplomacy between the two countries in the early Korea-Japan relationship in the medieval era. The research results are as follows. A good-neighbor Policy in the early Chosun Dynasty was established by a link of a barbarian ban policy to blockade the frequent intrusion by Japanese barbarians. The exchange was the form of presenting a return present in return for a tribute to the Chosun Dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. In trading goods between Korean and Japan. the imported goods from Japan to Korea were a wide variety of items primarily such as dyes, mordant, medicines, steel, spicers, etc. In particular, Somok used as a red mordant, which were intermediate goods to Southeast Asia, was the most heavily-traded items of imported goods from Japan. It had been consumed primarily as a raw material making the costume suit of the royal family and the aristocracy. The increased import of Somok was derived from a thought of preferred red color by our people. As its inflow was increased. the costumes tended to be luxurious In early Chosun Dynasty and resulted in social issues. This active trading from the early Chosun Dynasty caused from the communication of the Japanese envoy. In addition the study of the trading provided an opportunity that can glance at an aspect of the costume culture, though It was fractionary.

Recently, localized heavy rain storms have been occurring frequently due to global warming, and it is difficult to shield a large number of facilities against disaster with limited manpower. The unmanned water treatment system uses five senses to analyze various judgment criteria, which are set according to field situations such as machine vibrations, the temperature of bearings, the sound of the operating machines, and the hydraulic pressure, current, and voltage of the hydraulic floodgates. It thus judges normal or abnormal operation status and conducts unmanned control of such machines. It automatically applies a system to the interruption of communications and therefore improves the reliability of its unmanned irrigation facilities. It maximizes the operational efficiency of managers responsible for various fields, enabling them to discharge water before the situation escalates to a crisis within the golden time, and to protect against damage to humans and property.

This research is to reveal an aspect of costume culture and a phase of the cloths in the relationship of the Chosun dynasty, by considering the exported goods from the Chosun dynasty of the trading goods derived by the trade diplomacy between the two countries in the Chosun dynasty-Japan relationship in the 15th and 16th. The research findings, by analyzing various literatures and related documents, follow. The research results are as follow. The exchange was the form of presenting a return present in return for a tribute to the Chosun dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. The imported goods were somok, peppers, drug-stuffs, gold, bronze, sulfur, etc. The exported goods were books and cloths, such as hemp cloths, cotton cloths, silk, etc. The majority of exported goods was cloths, particularly cotton cloths. Meanwhile, in the 15th and the 16th century, with expanding of active trade towards Japan, the amount of export increased rapidly. As a result of the increase of exporting cotton cloths, the raw cottons production was increased and cotton cloth manufacturing was developed. However, it also expanded a dual structure of cotton cloths between the cotton cloths for exports and the cotton cloths for domestic markets. This dual structure of cotton cloth was lead to the deterioration of cotton cloths and had an effect on the price increases of domestic markets.

To investigate the effects of wearable near-infrared ray-emitting knee pads on knee pain among elderly adults in Korea. Randomized controlled trial evaluating the effects of near-infrared rays (NIR) on knee pain in Korean elderly adults. Five community-based research facilities (two welfare centers, a senior citizen center, and two churches). Forty-seven participants aged 65 years and older who had experienced knee pain. The experimental group (n = 25) wore NIR-emitting knee pads for one month at nighttime while sleeping. The control group (n = 22) wore knee pads without NIR. Demographic characteristics, intensity and duration of knee pain, amount of analgesic medication used, range of motion, gait speed, and health-related quality of life were collected using questionnaires. The experimental group showed decreased intensity (t = -6.17, p < 0.001) and duration (t = -3.34, p = 0.002) of knee pain and reduced analgesic use (t = -2.30, p = 0.026) compared to the control group. NIR may be an effective non-pharmacological option for relieving knee pain in elderly adults.

Purposes: The purposes of this study were to evaluate parent satisfaction with inpatient hospital services in children's hospitals and to identify variables related to parent satisfaction. Method: A descriptive correlation study was conducted. Parents of 165 children who were inpatients in two children's hospitals participated in the study. Data were collected using structured questionnaire at the time of discharge. For statistical analysis, t-test, ANOVA, and Pearson correlation analysis were used. Results: The highest parent satisfaction domain was nursing service, and the lowest parent satisfaction domain was hospital service and accommodations. Parents were less likely to be satisfied with hospital facilities, equipment, noise and cleaning and less likely to be satisfied with the lack of information they received and with the lack of communication with health care professionals. Parents with longer length of stay and with older children reported higher satisfaction than their counterparts. Moreover, parent satisfaction was related to their intention to revisit and related to intention to recommend this surveyed hospital over others. Conclusions: Efforts to improve parent satisfaction in children's hospital service and accommodation are needed to improve the quality of health care. Communication by health care professionals with parents and a partnership between parents and health care professionals are necessary to improve quality of care.
