This Study has attemped to compare the health care systems of South and North Korea. There has been a wide difference in the health care System between the South and North of Korea. In this paper, I have also shown that each health care system has its own unique response to the social, political, and economic conditions of the country. Therefore the author analyzed and summarized the important difference of health care system between the South and the North of Korea as follows. 1. Compared with the Laissez-faire health care system of South Korea, North Korea has the state socialistic health care system which provide health care services to the people free of charge. And the North Korea is marking positive efforts toward the scientification and systemization of Oriental Medicine which is called Dongui-Hak in the North-on the basis of Ju-Che idea. 2. North Korea's health care system appears to be strongly geared toward extensive and preventive treatment and launched the massive sanitary propagation campaign. which have resulted in a great success. North Korea has a system of universal comprehensive care for its population. The government has a central role in planning and regulating health care. 3. The government also employs physicians, nurses, and other professionals to provide health care to patients at public expense. In North Korea, health professionals are government employees. They work for a salary and the system is funded through general taxation. 4. In the North Korea, health services area system of the cities and countre's unit is strictly conducted along with the doctor's area responsibility system. And so without referal card, patients can not use the upper-grade medical facilities. The health care delivery system of North Korea is made up of the fourth level procedue unlike South Korea. 5. General office of Oriental Medicine, Academy of Oriental Medical Science and Guidance Bureau of Oriental Medicine are established in the organization of the Department of Health in the North Korea. And nowadays much emphasis are equally placed on the Oriental Medicine as well as Western Medicine. Both South and North Korea have faced with a critical moment of developing a mutually agreeable and acceptable system of health care for the unified nation.

This study is to investigate the change of intelligent and affective domains through the student self-evaluation to identify causes of wrong answers. Through this evaluation, students could have opportunities to solve the given mathematical problems basically and to reflect their problem-solving process, and further to recognize which mathematical content(concepts or expressions, symbols, etc.) led them to solve the problems incorrectly or wrong. Through this process, they would correct their wrong process and answers and to reinforce the prerequisite knowledges relevant to the problems, and furthermore, to enhance problem-solving abilities. To accomplish this, this study was executed as a case study on the subject of four tenth graders. The subject consisted of two boys and two girls. In this study, three essay types of mathematical problems in tenth grade level were chosen from several domestic tests in Korea. Based on the original three essay type of problems, three types of similar problems, namely equivalent problem, similar problem, and isomorphic problems were reconstructed, respectively by the researchers. The subjects were guided to solve the original three problems, and they corrected their wrong parts of the first problem of the three problems. They solved an equivalent problem of the first problem and executed self evaluation and also corrected wrong parts. Next, they dealt with a similar problem of the first problem and executed self evaluation and also corrected wrong parts. Next, while dealing with an isomorphic problem of the first problem, the subjects did the same things. Thus, for the second and third original problems, the study was implemented in the same way. To explore their intelligent and affective domains through student self-evaluation in-depth, the subjects were interviewed formally before and after conducting the experiment and interviewed informally two times, and the recordings were audio-typed.

This study was conducted to investigate the quality of sleep of university students according to smoking behavior and to generate basic data for use in development of smoking prevention and smoking policies for university students and young adults in their 20s. The quality of sleep of 291 college students was measured based on smoking behavior and the Pittsburgh Sleep Quality Index (PSQI) questionnaire from May 29, 2017 to June 3, 2017. Multiple logistic regression analysis with step-wise analysis revealed that the quality of OR increased from 2.542 to 2.820 times as the grade increased, and that OR was 3.126 times higher than that of non-smokers and stop-smokers. The quality of sleep worsened with OR=12.388 times. Among general smokers, 72.4% of the students had poor sleep quality, but 82.6% of the students who did not have good sleep quality of electronic-cigarette or tobacco smokers had electronic-cigarette or tobacco worse than regular tobacco.Based on these findings, quitting smoking is essential to improve quality of sleep, but this can be difficult. Therefore, it is necessary to develop legal regulations and policies at the national level. Moreover, a system or service that can manage phased smoking cessation is needed.

This study was conducted to evaluate the effect of dietary supplementation with rice bran, flax seed, or sunflower seed to finishing native Korean cattle (Hanwoo) on growth performances, carcass characteristics, fatty acid composition, free amino acid and peptide contents, and sensory evaluations of Longissimus muscle (LM). A total of 39 Hanwoo steers (average age of 22.2 mo and average body weight (BW) of 552.2 kg) were randomly divided into Control, rice bran (RB), flax seed (FS), or Sunflower seed (SS) groups. The steers were group fed for 273 d until they reached an average age of 31.2 mo. Final BW was 768.2, 785.8, 786.2, and 789.0 kg, and average daily gain was 0.79, 0.85, 0.82, and 0.84 kg for the Control, RS, FS, and SS groups, respectively (p>0.05). Fat thickness of the FS group (19.8 mm) was greater (p<0.05) than that of the other groups. Final yield grade converted into numerical values was 2.0 for the RB group, 1.7 for the Control and SS groups, and 1.4 for the FS group. Marbling degrees for the Control, SS, RB, and FS groups were 5.3, 5.1, 4.7, and 4.6, respectively. Percentages of palmitic acid ($C_{16:0}$), stearic acid ($C_{18:0}$), and arachidic acid ($C_{20:0}$) in the LM were not different among the groups. Palmitoleic ($C_{16:1}$) acid was higher (p<0.05) in the SS group. The concentration of oleic acid was highest (p<0.05) in the Control group (47.73%). The level of linolenic acid ($C_{18:3}$) was 2.3 times higher (p<0.05) in the FS group compared to the other groups. Methionine concentration was (p<0.05) higher in FS (1.7 mg/100 g) and SS (1.2 mg/100 g) steers than in the Control or RB groups. Glutamic acid and ${\alpha}$-aminoadipic acid (${\alpha}$-AAA) contents were (p<0.05) higher in the FS group compared to the other groups. LM from the FS group had numerically higher (p>0.05) scores for flavor, umami, and overall palatability in sensory evaluations. In conclusion, supplementation of flax seed to diets of finishing Hanwoo steers improved sensory evaluations which might have been caused by increases in flavor related amino acids such as methionine, glutamic acid and ${\alpha}$-AAA and peptides, anserine and carnosine, and their complex reactions.

The purpose of this study was to examine the relationship between anger expression and self-esteem of female college students of dental hygiene. Participants were 598 female students who majored in dental hygiene from randomly selected colleges, located in Daejeon and Chungcheongbuk-do. Data were gathered from May 20 to June 5, 2014, using structured questionnaires. The major findings of the study were as follows: the correlation between anger expression and self-esteem was analyzed, and self-esteem was found to have a weak significant negative correlation with anger expression. On analyzing data to explore which variables affected self-esteem, it was found that self-esteem was influenced by grade, school record, harassment, language psychological violence, and bullying. The above-mentioned findings suggest that anger expression is related to self-esteem. After graduation from college, dental hygiene students, encounter a variety of interpersonal relationships in their work. Therefore self-esteem programs need to be developed and implemented at an individual, departmental, and collegiate level to help students learn to respect themselves and others, and to provide appropriate care.

Nurses experience role conflict between nursing theory that they learned in school and clinical nursing practice. This conflict lead to lower self-image, self-esteem, job dissatisfaction. Also, the professionalism of nurses is estimatable by the grade of autonomy. The professional autonomy requires individual and professional obligation about her decision and performance. A lack of professional autonomy results in the Job dissatisfaction. Job dissatisfaction leads to absenteeism, increased proneness to mental and physical illness and higher turnover rates. The purpose of this study was to investigate professional autonomy and self-concept of clinical nurses. Data were collected from 262 clinical nurses in P city from June 1 to June 30, 1996. The instruments used for this study were made by Arthur(1990) and Schutzenhofer(1983). The data were analyzed for frequency and percetage, mean, SD, t-test, ANOVA, Pearson's correlation coefficient, stepwise mutiple regression, using SAS $PC^+$ Program. The findings were as it follows : 1. The mean of professional autonomy and self-concept were $152{\pm}18.48,\;70.65{\pm}8.20$(2.62), respectively. These showed mid level of professional autonomy and self-concept. 2. Professional autonomy of clinical nurses was found to vary significantly according to total years of clinical experience(F=4.49 p<0.01), position(F=3.49 p<0.05), and state under study for the degree(F=3.83 p<0.05). Professional self-concept was found to vary significantly according to age(F=3.52 p<0.05), marital status(F=7.39 p<0.001), total years of clinical experience(F=3.59 p<0.05), position(F= 5.22 p<0.01), the expectant period being on the duty as clinical nurse(F=8.34 p<0.001), and motivation of choosing nursing(F=5.17 p<0.001). 3. The statistical relationship between clinical nurses' professional autonomy and self-concept was found as positive correlation(r=0.42246 p<0.001). 4. Professional autonomy was the highest factor predicting professional self-concept(17.85%). Professional autonomy and marital status accounted for 20.60% in professional self-concept of clinical nurses. In conclusion, Professional autonomy and self-concept of clinical nurses showed significantly positive relationship. Therefore, nursing education needs to develop programs and policies to increase professional autonomy and self-concept of clinical nurses.

The purpose of this study is to investigate the relationship between cognitive levels and achievement of science process skills. A science laboratory process skills test based on optional instrument of the SISS was administered to a sample of 162 students in the 8th grade. Practical assessment tasks consisted of the contents about acid, base, density, and a property of cobalt chloride. The format of this practical test was the station type that students had to conduct a short activity. Science process skills included three sub-skills which were categorized as designing, performing, and reasoning. As cognitive levels develop from concrete operational stage to transition stage and formal operational stage. total scores of science process skills and mean scores of sub-skills were significantly increased. Regardless of cognitive levels. all students were more successful on performing than designing or reasoning. In case of being controlled cognitive levels, gender differences and area differences were not detected in achievement of science process skills. According to these results. there was a strong relationship between cognitive levels and achievement of science process skills by practical assessment. This study implies that considering student's cognitive levels is very important for improving science process skills.

The student's pre-questions (pre-class questions related to the learning contents) not only provide the teacher a gauge of the interest and level of the student, but also provide a useful means of providing clues to proceed with the teaching-learning process. The purpose of this study is to develop an analytical framework for effectively analyzing students' pre-questions and to analyze students' pre-questions related to elementary science learning unit of the 2009 revised curriculum by applying this framework. The developed framework is composed of three major categories: knowledge type, extended type, and curious type, each of which is then subdivided into several sub-categories. Using the developed analysis framework, 914 pre-questions from the students presented in the $5^{th}$ and $6^{th}$ grades of elementary science in the 2009 revised curriculum were analyzed, and the types of questions distributed by grade. The percentage of questions by type was also different. Based on the results of this study, students' needs for learning can be grasped through the pre-questions analysis framework and reflected in the teaching-learning process, and student-centered learning contents and methods could be presented. It is expected to make a meaningful contribution to the analysis framework.

This study was carried out to find the relationship among dietary behavior, dietary self efficacy and nutrition knowledge according to the perceived body shape of the 5th and 6th grade elementary students in Gangwon Province and found out their relationships. The results are as follows; The factors that showed significant difference according to perceived body shape were gender, father's education level, the number of siblings, birth order, obesity of parents and siblings and ideal body shape. For the perceived body shape, the students answered generally normal(48.9%), slightly fat(27.9%), thin(16.5%) and very fat(6.7%). Out of total students 76.5% of them were not satisfied with their body shape such that satisfactory(23.5%), want to lose weight(61.4%) and want to increase weight(15.1%). The score of eating behavior showed significant difference between perceived body shape on such questions as eating speed(p<0.001), frequency of fatty food intake(p<0.001), adequate intake quantity(p<0.001), balanced diet(p<0.05), frequency of going out to eat(p<0.001). The score of diet self efficacy showed significant difference in the area of general habit on such questions as whether to eat slowly together with friends (p<0.001), whether to eat adequate quantity(p<0.001), whether not to have snacks after dinner(p<0.001). And in the area of food selection it showed significant difference on such questions as to select ice cream in stead of yoplait(p<0.001). In the area of social circumstance it showed significant difference on such questions as to reject the food(p<0.01) and to restrain food in birthday party or holiday(p<0.05). In the area of emotional status it showed significant difference on the question about food restrain when boring and depressed(p<0.05 respectively). The score of nutrition knowledge showed significant difference according to the perceived body shape on such questions as total score(p<0.01), five basic food group(p<0.05), snack and body weight(p<0.001), calcium function(p<0.01). It showed perceived body shape co-related with the nutrition knowledge(p<0.01). In summary, the perceived body shape for the highly eating behavior was generally normal, for the highly dietary self efficacy was slightly fat, and for the highly nutrition knowledge was also slightly fat.

Background: While 5-port laparoendoscopic radical prostatectomy is standard practice, efforts have been focused in developing a single port surgery for cosmetic reasons. However, this is still in the pioneering stage considering the challenging nature of the surgical procedures. We have therefore focused on reduced port surgery, using only 2-ports. In this study, we compared 2-port laparoendoscopic radical prostatectomy (2-port RP) and conventional 5-port laparoscopic radical prostatectomy (LRP) for clinically localized prostate carcinoma and evaluated the potential advantages of each. Materials and Methods: From January 2010 to December 2010, all 23 patients with clinically localized prostate cancer underwent LRP. Starting November, 2010, when we introduced the reduced port approach, we performed this procedure for 22 consecutive patients diagnosed with early-stage prostate cancer (cT1c, cT2N0). The patients were matched 1:1 to 2-port RP or LRP for age, preoperative serum PSA level, clinical stage, biopsy and pathological Gleason grade, surgical margin status, pad-free rates and post-operative pain. Results: There was a significant difference in operative time between the 2-port RP and LRP groups ($286.5{\pm}63.3$ and $351.8{\pm}72.4$ min: p=0.0019, without any variation in blood loss (including urine) ($945.1{\pm}479.6$ vs $1271.1{\pm}871.8ml$: p=0.13). The Foley catheter indwelling period was shorter in the 2 port RP group, but without significance ($5.6{\pm}1.8$ vs $8.0{\pm}5.6$ days: p=0.057) and the total perioperative complication rates for 2 port RP and LRP were comparable at 4.5% and 8.7% (p=0.58). There was an improvement in pad-free rates up to 6 months follow-up (p=0.090), and significantly improvement at 1 year (p=0.040). PSA recurrence was 1 (4.5%) in 2-port RP and 2 (8.7%) in LRP. Continuous epidural anesthesia was used in most of LRP patients (95.7%) and in early 2-port RP patients (40.9%). In these patients, average total amount of Diclofenac sodium was 27.8mg/patient in 2-port RP and 50.0mg/patient in LRP. Conclusions: Thus the reduced port approach is as efficacious as LRP in terms of many outcome measures, with significant cosmetic advantages and reduction in post surgical pain. This method can be readily performed safely and therefore can be recommended as a standard laparoscopic surgery for prostate cancer in the future.
