  • This paper describes two kinds of personal hand-held electronic devices to support marine leisure safety. The one is Radar response-type safety device triggering by the pulse signal from a commercial 9GHz-band Radar to provide quick search and rescue with combined civilian-government-military fleets. The other one is M-RFID (Marine Radio Frequency IDentification) based safety electronic device using 900MHz Tx/Rx with spread spectrum frequency hopping and GPS. Through the field tests at sea using Korea Coast Guard's warship the operating performances are verified. Further plan for practical use of each device was also discussed.

  • The aim of this study is selection of the male-sterile plant for inhibiting transgene flow through gamma-irradiation ($^{60}Co$) at the pollination and fertilization cycle of herbicide-tolerant genetically modified (GM) zoysiagrass (Zoysia japonica Steud.). High frequencies of plant mutations were obtained about 18% from $M_1$ generation at the doses (10 to 50 Gy). We also found that some $M_1$ plants showed male-sterile plants using de-husked seeds and comparison of stainable pollen using $KI-I_2$ solution. Besides the effects of irradiation on pollination and fertilization cycle, various other mutations like dwarf, cold tolerance, increasing grains and mass were observed. Four of dwarfism plants were selected through comparison of morphological characteristic between control and mutants during 4 years. These results demonstrated that the gamma-irradiation on pollination and fertilization cycle is very effective to induce the various mutations, and the male-sterile mutants are useful for controlling transgene flow and developing of high quality turfgasses.

  • Objectives: The aim of this study was to investigate trends of oral health behaviors in Korean adolescents. Methods: From the 2005 to 2017 Korea Youth Risk Behavior web-based Survey (KYRBS) Secondary Data (study to 748,461). Independent variables were the year, gender, grade, and living area. Dependent variables were the rate of tooth-brushing after lunch, scaling, use of sealant, and oral health education within 1 year. Chi-squire tests were used to estimate the rate of oral health behaviors and trends. In addition, multiple logistic regression analysis was used to estimate the association between socio-economic characteristics and oral health behaviors. The analyses were conducted using IBM SPSS statistics 21 (version 21.0, IBM Corporation, New York, NY, USA). Results: The rate of tooth-brushing after lunch and use of sealant have significantly increased every year. Oral health behaviors were significantly associated with socio-economic characteristics. The rate of oral health education was higher among males than females, which was in contrast to other oral health behaviors. The scores for tooth-brushing after lunch, use of sealant, and scaling in females were 2.33 (95% CI; 2.27-2.40), 1.31 (95% CI; 1.29-1.33), and 1.20 (95% CI; 1.18-1.22), which were higher than those in males. The score for use of sealant in the highest household economy group was 1.13 (95% CI; 1.10-1.17), which was higher than the lowest economy group. Conclusions: We found positive trends of oral health behaviors in Korean adolescents.

  • This study aimed to determine the association between stress recognition and oral symptom experiences among adolescents. We analyzed it, based on the 14th Korea Youth Risk Behavior Web-based Survey (2018), using the chi-square test and logistic regression. The distribution rate of stress recognition and oral symptom experience within one year were 81.7% and 48.9%, respectively. The group with stress recognition had a higher rate (52.2%) of oral symptom experience than the group that did not recognize stress (p<0.001). In the stress recognition group, the odds ratio for oral symptom experience was 1.86 (95% CI: 1.78-1.95). We suggest that stress is associated with oral health in adolescents. In the future, it will be necessary to study stress relief and oral health education in adolescents.

  • Purpose: This study aimed to develop a client-centered integrated home nursing care model for rural areas by analyzing public health nursing, hospital-based home care services, and long-term nursing care in Korea. Methods: The literature review performed included data from the National Assembly Library, DBpia, RISS, and KISS, Google Scholar, the Ministry of Government Legislation, Statistics Korea, and the Ministry of Health and Welfare. Results: The client-centered and integrated home nursing care model in a rural area was opened as the Home Nursing Care Center in a public health center operating directly or on consignment. This model provides both a hospital-based home care services as well as long-term care, in accordance with the health status of the client and difficulty of nursing services. Moreover, the nurse who worked in a sub-organization (Centers for Supporting Healthy Living, Public Health Units, and etc.) of the public health center as care coordinator and case manager facilitates to connect home nursing care services and social welfare services. Conclusions: Our data indicates that the client-centered integrated home nursing care model in rural areas effectively combines professional services, regional accessibility, and social welfare services.

  • Rice bodies are commonly detected in adults with rheumatoid arthritis and rarely occur in children. An 11-year-old female adolescent who visited our hospital for evaluation of knee pain underwent a MRI scan, which revealed an intra-articular mass. Arthroscopic examination of the mass confirmed conglomerated rice bodies. We report a case of rice bodies that clinically presented as intra-articular masses.

  • The purpose of this research was to uncover the expertise of ICU nursing in Korea, and to describe nurses' practice based on the degree of skill acquisition. A total of 18 ICU nurses participated in the study. The data was collected through individual in-depth interviews and it was managed using the NUDIST 4.0 software program. The data was analyzed using interpretive phenomenology suggested by Benner. Four properties of expertise of ICU nursing were identified. These are 1) concern and love toward patients; 2) knowledge; 3) skill, and 4) abilities in interpersonal relationships. And the characterisitcs of four levels of skill acquisition, that is advanced beginner, competent, proficient, and expert, were described with exemplars. The results of this study might help nurse researchers clarify and elaborate on the concept of expertise in ICU nursing, and enable them to understand how the process of skill acquisition occurs in the ICU setting. They might also help nurse managers establish educational goals for ICU nursing for student or novice nurses.

  • Temporomandibular joint (TMJ) pain is characterized by persistent jaw pain associated with dysfunction and tenderness of the temporomandibular muscles and joints. The aim of this study was to investigate whether treatment with red or black ginseng extract helps in the modulation of inflammatory TMJ pain. Male Sprague-Dawley rats weighing 220~260 g were used. The experimental group was subdivided into 4 groups based on the treatment method (n=6, each group): formalin (5%, $30{\mu}l$), formalin after distilled water (vehicle), formalin after red or black ginseng extract (per oral, single or repeated, respectively). To induce TMJ pain, $30{\mu}l$ of formalin was injected into the articular cavity under ether inhalation anesthesia. The number of noxious behavioral responses of scratching the facial region proximal to the injection site was recorded for 9 successive 5-min intervals following formalin injection. Repeated treatment with red or black ginseng extract reduced the nociceptive responses in the second phase (11~45 min). Nuclear factor erythroid 2-related factor 2 (Nrf2) is an oxidative stress-mediated transcription factor. Both ginsengs significantly down-regulated the increased Nrf2 level compared to the vehicle group. In the test for liver and kidney functions, repeated treatment with red or black ginseng was not different compared to the vehicle group. These results indicate that red and black ginseng extract might be promising analgesic agents in the treatment of inflammatory TMJ pain.
