The three major sleep disorders in Korea are snoring, sleep apnea, and insomnia. Lack of sleep is the root of all diseases. Some of the most serious potential problems associated with sleep deprivation are cardiovascular problems, cognitive impairment, obesity, diabetes, colitis, prostate cancer, etc. To solve these problems, the Korean government provided low-cost national health insurance benefits for polysomnography tests in July 2018. However, insomnia patients still have problems getting treated in terms of time, space, and economic perspectives. Therefore, it would be better for insomnia patients to be allowed to test at home. The measuring device can measure six biosignals (eye movement, tossing and turning, body temperature, oxygen saturation, heart rate, and audio). A gyroscope sensor (MPU9250, InvenSense, USA) was used for eye movement, tossing, and turning. The input range of the sensor was in 258°/sec to 460°/sec, and the data range was in the input range. Body temperature, oxygen saturation range, and heart rate were measured by a sensor (MAX30102, Analog Devices, USA). The body temperature was measured in 30 ℃ to 45 ℃, and the oxygen saturation range was 0% for the unused state and 20 % to 90 % for the used state. The heart rate measurement range was in 40 bpm to 180 bpm. The measurement of audio signal was performed by an audio sensor (AMM2742-T-R, PUIaudio, USA). The was -42 dB ±1 dB frequency range was 20 Hz to 20 kHz. The measured data was successfully received in wireless network conditions. The system configuration was consisted of a PC and a mobile app for bio-signal measurement and data collection. The measured data was collected by mobile phones and desktops. The data collected can be used as preliminary data to determine the stage of sleep and perform the screening function for sleep induction and sleep disturbances. In the future, this convenient sleep measurement device could be beneficial for treating insomnia.

This study was designed to investigate the status of orthodontic treatment and facial plastic surgery among 389 patients who visited dental clinics located in Seoul and Gyeonggi Province. After the collection of data, an analysis was carried out using a spss statistical program. The analysis results are as follows. the level of satisfaction with orthodontic treatment from patients with experience of the orthodontic treatment turned out to be high(p<0.01). Women considered 3.01 to 4 million won to be reasonable cost for orthodontic treatment (p<0.05), which is higher cost recognized by men, and patients with experience of orthodontic treatment recognized 19 to 24 months as the proper orthodontic treatment period(p<0.01). In addition, women showed higher figures than men in their awareness on the need for orthodontic treatment checkups(p<0.001), and facial plastic surgery experience (p<0.01). With respect to the part of the face on which they hoped to have plastic surgery, eye plastic surgery was higher in women (p<0.01), and nose surgery turned out to be higher in patients with experience of orthodontic treatment(p<0.05). Meanwhile, women considered the eye as the most important part among other facial areas (p<0.001), and they recognized that dentist should perform plastic surgery on both jaws among facial areas(p<0.01). In conclusion, the dental medical staff should provide consultations and operate treatment systems in consideration of gender differences and needs of dental patients. In the case of orthodontic treatment for the improvement of facial appearance, especially double jaw surgery which is closely related to the oral function, professional dental medical staff needs to perform the operation, considering the special oral environment. In addition, it is determined that provision of relevant medical information and promotion of dental service is required to provide patients with correct knowledge about orthodontic treatment and facial plastic surgery.

Objective: Infection is very common in the elderly, so there is a high prevalence of antibiotics use among this population. Especially, due to the emergence of resistant bacteria, the use of vancomycin is growing. The purpose of this study was to evaluate risk factors associated with vancomycin-induced nephrotoxicity in elderly patients. Methods: The subjects of this study were patients over 18 years old who received intravenous vancomycin in a general hospital located in Gangneung-si, Korea between August 1, 2013 and July 31, 2015. Data collection regarding vancomycin use and baseline characteristics was conducted using computerized hospital database. Logistic regression analysis was used to identify risk factors associated with vancomycin-induced nephrotoxicity. Results: A total of 290 patients were finally included, and 191(66%) out of these patients were age 65 or older. The incidence of vancomycin-induced nephrotoxicity was 11.0%, 12.6%, and 7.0% in the all adult patients, the elderly patients, and the non-elderly patients, respectively. There were significant differences in comorbidities between patients with nephrotoxicity and patients without nephrotoxicity in the all adult patients, and there were significant differences in vancomycin duration, comorbidities, and number of nephrotoxic agents between patients with nephrotoxicity and patients without nephrotoxicity in the elderly patients. However, according to the logistic regression analysis, there was no significant risk factor that increases the incidence of vancomycin-induced nephrotoxicity in all three age groups. Conclusion: There were no differences in risk factors that increase the incidence of vancomycin-induced nephrotoxicity between all adult patients, elderly patients, and non-elderly patients. Further studies with larger sample sizes to identify risk factors associated with vancomycin-induced nephrotoxicity in the elderly to improve the outcome of pharmacotherapy are required.

1. About fifty thousand of cattle embryos were transferred and 16000 ET-calves were born in 1999. Eighty percents of embryos were collected from Japanese Black beef donors and transferred to dairy Holstein heifers and cows. Since 1985, we have achieved in bovine in vitro fertilization using immature oocytes collected from ovaries of slaughterhouse. Now over 8000 embryos fertilized by Japanese Black bull, as Kitaguni 7~8 or Mitsufuku, famousbulls as high marbling score of progeny tests were sold to dairy farmers and transferred to their dairy cattle every year. 2. Embryo splitting for identical twins is demonstrated an useful tool to supply a bull for semen collection and a steer for beef performance test. According to the data of Dr. Hashiyada(2001), 296 pairs of split-half embryos were transferred to recipients and 98 gave births of 112 calves (23 pairs of identical twins and 66 singletons). 3. A blastomere-nuclear-transferred cloned calf was born in 1990 by a joint research with Drs. Tsunoda, National Institute of Animal Industry (NIAI) and Ushijima, Chiba Prefectural Farm Animal Center. The fruits of this technology were applied to the production of a calf from a cell of long-term-cultured inner cell mass (1988, Itoh et al, ZEN-NOH Central Research Institute for Feed and Livestock) and a cloned calf from three-successive-cloning (1997, Tsunoda et al.). According to the survey of MAFF of Japan, over 500 calves were born until this year and a glaf of them were already brought to the market for beef. 4. After the report of "Dolly", in February 1997, the first somatic cell clone female calves were born in July 1998 as the fruits of the joint research organized by Dr. Tsunoda in Kinki University (Kato et al, 2000). The male calves were born in August and September 1998 by the collaboration with NIAI and Kagoshima Prefecture. Then 244 calves, four pigs and a kid of goat were now born in 36 institutes of Japan. 5. Somatic cell cloning in farm animal production will bring us as effective reproductive method of elite-dairy- cows, super-cows and excellent bulls. The effect of making copy farm animal is also related to the reservation of genetic resources and re-creation of a male bull from a castrated steer of excellent marbling beef. Cloning of genetically modified animals is most promising to making pig organs transplant to people and providing protein drugs in milk of pig, goat and cattle. 6. Farm animal cloning is one of the most dreamful technologies of 21th century. It is necessary to develop this technology more efficient and stable as realistic technology of the farm animal production. We are making researches related to the best condition of donor cells for high productivity of cloning, genetic analysis of cloned animals, growth and performance abilities of clone cattle and pathological and genetical analysis of high rates of abortion and stillbirth of clone calves (about 30% of periparutum mortality). 7. It is requested in the report of Ministry of Health, labor and Welfare to make clear that carbon-copy cattle(somatic cell clone cattle) are safe and heathy for a commercial market since the somatic cell cloning is a completely new technology. Fattened beef steers (well-proved normal growth) and milking cows(shown a good fertility) are now provided for the assessment of food safety.

The Illness Management and Recovery(IMR) Program was designed to improve self-management and recovery of people with mental illness. The purpose of this study was to identify the effects of the Korean version of the IMR program on recovery, knowledge against mental illness, hope among inpatients with severe mental illness. 92 participants diagnosed with schizophrenia, bipolar disorder and schizoaffective disorder were assigned to either an IMR group(n=51) or the control group(n=41) without randomization. Data collection had been conducted from June 2015 to December 2016. Mental Health Recovery Scale, Knowledge Scale, and Hope Scale was administered to participants before and after the intervention. Participants in the IMR program showed significant improvement in progress toward their recovery and knowledge about their mental illness compared with those receiving treatment as usual. However, changes in hope were not significant in both groups. This is the first evaluation of the effects of the Korean version of the IMR program. Our findings support potential benefits of implementing the Korean version of the IMR program.

This study was conducted to clarify the mediating effects of self-efficacy and organizational commitment on the level of depression associated with emotional labor and occupational stress of call center representatives. The survey subjects were 486 representatives working in four call centers in D city. Data collection was conducted using structured, self-addressed questionnaires from January 5th to 25th, 2017. The results showed that the depression level of the representatives was significantly higher in the emotional labor and occupational stress groups and higher in the low self-efficacy and organizational commitment groups. The correlations between variables revealed a positive correlation between depression, emotional labor, and occupational stress, but a negative correlation between self-efficacy and organizational commitment. Path model analysis revealed that emotional labor and occupational stress had positive effects on depression, while self-efficacy and organizational commitment was negatively influenced. In addition, self-efficacy and organizational commitment had a mediating effect on emotional labor and depression, while organizational commitment had a mediating effect on occupational stress and depression. Therefore, to reduce the depression level of call center representatives, it is necessary to reduce the emotional labor and occupational stress factors, as well as to have a mental health mediation plan to increase self-efficacy and organizational commitment.

This study was conducted to compare the resilience, social support, psychosocial stress and burnout between novice and experienced nurses. Data collection was conducted using structured questionnaires for 65 novice nurses with less than one year of clinical experience and 70 experienced nurses with at least seven years of clinical experience working in general hospitals. The results revealed that the resilience of novice nurses was lower than that of experienced nurses, and there were significant differences according to educational level, job satisfaction, and subjective health status. Conversely, experienced nurses' resilience differed according to their position. In addition, the resilience of novice and experienced nurses showed the highest correlation with psychosocial stress (r=-0.633, p<0.001; r=-0.586, p<0.001), while novice nurses' social support (r=0.560, p<0.001) and experienced nurses' burnout (r=-0.404, p=0.001) showed the second highest correlations. These results demonstrate that the factors related to resilience of novice and the experienced nurses differ. Therefore, it is necessary to develop a differentiated program according to the characteristics of resilience of each nurse to improve the resilience of novice and experienced nurses.

This descriptive study was done to identify the relationship between coping style and trait anxiety in patients undergoing cardiac catheterization. The subjects selected were 69 patients who were scheduled for cardiac catheterization in S hospital from , November 1st, 1994 to May 30th, 1995. Data collection was done using Spielberger's Trait Anxiety Scale, Bendig's Short Form of the Manifest Anxiety Scale, Crowne & Morlowe's Social Desirability Scale, Millers Behavioral Style Scale, Information Subscale of Krantz Health Opinion Survey and Visual Analog Scale about informaton seeking behavior. The summary of the findings is as follows : 1. No significant relationship was found between the general characteristics of age, sex, marital status, level of education and occupation, and the variables coping style and trait anxiety. 2. The mean of trait anxiety scores for the Spielberger Scale was 46.68. It is slightly above average. The subjects were classified as to personality type: truely low anxious 25 (36.2%), highly anxious 25 (36.2%), and repressing 16 (23.2%), using a combination of scores from the Bendig Short Form Anxiety Scale and the Crowne Marlowe Social Desirability Scales. 3. No significant relationship was found between Spielberger s trait anxiety and Bendig's personality type. 4. Each subject's preference for either monitor or blunter coping strategy was assessed via the Miller Behavioral Style Scale. The proportion of Monitors (47.8%) and Blunters (52.2%) among the subjects were similar. The means of preference for information measured on the Krantz's subscale and Visual Analog Scale were 4.18, 80.79 respectively. Because these scores appeared above average, subjects tended to be higher seeker an information rather than avoiding it. 5. There was no significant relationship between Miller's Behavioral Style and Spielberger's trait anxiety. 6. There was no significant relationships between Bendig's personality types. and the preference on information of Krantz's and Visual Analog Scale. and Miller's Behavioral Styles. But 56.0% of the subjects who were highly anxious used Monitor strategy for coping. Findings from the current study do not permit any relationship inferences between coping style and trait anxiety. Patients undergoing cardiac catheterization must receive interventions on stress reduction because the cardiac 'catheterization creats a situation of psychological stress. Therefore, the nursing intervention of providing information about cardiac catheterization have to be given based on each patient's coping style and on their trait anxiety.
