Objectives: The aim of this study was to investigate the attitudes toward complementary and alternative medicine among 1,490 residents(339 households) in Suwon city. Methods: All respondents were asked about types, frequency, effects, side-effects, views, and cost of complementary or alternative medicine through a questionnaire from July 24th to 27th. Six therapies were investigated: diet; acupuncture/ massage/ chiropractic etc., mind control such as Ki/ Yoga/ spiritual therapy/ relaxation therapy etc.; nutritional supplements, cultural remedies; and Herb medications Results: The results of this survey were as follows: 35.6% of respondents had experiences with at least one or more types of complementary and alternative medicine. The average number of different types of therapies used was 3.4. More experience with various types of therapies were found among those respondents of higher education, older age group, higher income, married group, religious group than among the opposite groups of respondents. Herb medications were used most frequently(39.8%), followed by minor grains(37.9%), Ginseng(23.8%), Boshintang(21.5%), acupuncture(20.3%), Gaesojou(15.3%) Gingko nut(12.0%), mushroom(11.5%), Cupping therapy(10.2%), and black goat(0.0%). Acupuncture and Herb medications were used for treatment of hypertension the most frequently; minor grains or silkworm for treatment of diabetic mellitus; vegetables for treatment of obesity; acupuncture, Cupping Therapy, Herb medications for treatment of rheumatism; and acupuncture, Herb medications, or exercises for treatment of Cerebro Vascular Accident(CVA). The average costs of treatment were 108,000 Won for hypertension, 87,200 Won for diabetic mellitus, 16,800 Won for obesity, 68,800 Won for rheumatism, and 87,500 Won for CVA. Among 10.9% of respondents, there were 13 cases of side-effects with acupuncture, Herb medications, and Gaesojou. Among the cases of side-effects, majority was due to Herb medications. Respondents reported that Cupping Therapy was the most effective, followed by acupuncture, Ginseng, Gingko nut, Boshintang, black goat, minor grains, Gaesojou, Herb medications, vegetables, and mushroom. In response to the views of complementary and alternative medicine which they had used, they recommended minor grains first, followed by Ginseng, acupuncture, Gingko nut, Cupping Therapy, vegetables, Boshintang, black goat, mushroom and Herb medications. In contrast, they did not recommend Herb medications, acupuncture, nor Gaesojou. Conclusions: These findings indicate that many people use various complementary and alternative medicine without any guidelines for treatment of serious chronic diseases not even to invigorate themselves. It is, therefore, suggested that medical doctors or scientists verify the true effects or side-effects from the most common complementary or alternative therapies through experiments. Also medical doctors should provide a comfortable atmosphere for discussion among doctors and patients who would like to try these therapies.

Researchers' common findings is that there are positive or negative effect of alcohol expectancy on drinking behavior. Therefore we would effectively prevent troublesome drinking of the youth and university students by inquiring and controlling critical factors affecting alcohol expectancy. The purposes of this thesis are, first, to empirically test factors affecting the alcohol expectancy level of elementary schoolchild(potential drinker).; second, to suggest the necessity for development of pre-alcohol prevention programs. On the basis of previous research, eighteen factors included in four categories(general characters, environmental characters, alcohol knowledge, drinking experience) affecting alcohol expectancy level were found out. 623 subjects used in this study were drawn from 8 elementary schools in Daegu, Korea. The empirical results suggested that the alcohol expectancy level of elementary schoolchildren was negative in general. And it was proved that 9 factors were significantly correlated with alcohol expectancy level. To put it concretely(see Fig.), (1) It was proved that schoolchildren with bad environment(live in oneself, displeased drinking feeling) rather than good environment(live with parents, nice drinking feeling) for drinking had more negative alcohol expectancy. (2) Korean traditional culture that partakes of sacrificial food and drink have an influence on the first drinking of most elementary schoolchildren. And it was proved that schoolchildren with this drinking experience rather than any other motives had less negative alcohol expectancy. (3) It was proved that schoolchildren adapting themselves rather than being difficult in school life had more negative alcohol expectancy. And the more knowledge about alcohol or drinking schoolchildren had, the more they had negative alcohol expectancy (4) It was proved that schoolchildren having drinking experience or drinking at present rather than having no drinking experience or not-drinking at present had less negative alcohol expectancy. (5) It was proved that schoolchildren having strong drinking intention rather than having weak or no drinking intention in the future had more positive alcohol expectancy. Based on previous results, guideline for development of pre-alcohol prevention programs can be represented: discriminated programs development on educatee, drinking education programs development increasing the power of self-control about alcohol and drinking, social education or continuing education programs development on drinking, open preschool education to substantially prevent drinking or alcoholism etc. The findings, however, should be interpreted with caution, because this study has several limitations in measurement and sampling as follows. First, selection bias because of limited selection of sampling. It is because the subjects are drawn from only 8 elementary schools in Daegu. Second, less refined measurement ; Therefore, it is necessary to develop more detailed measures on alcohol knowledge, alcohol expectancy level especially. Further researches should be suggested and encouraged with more refined methodologies.

A scanning eletron microscopic study was performed to observe the tegumental surface of adult Fibricola seoulensis. The adult worms were collected from the small intestine of mice 5 days to 3 weeks after experimental infection with the metacercariae. The metacercariae were obtained from the viscera of the snakes, Matrix tigrina lateralis, by artificial digestion technique. The results were as follows: 1. The tegument of anterior body was covered with cobblestone-like cytoplasmic processes and that of posterior body showed finger-like processes. The posterior body had 4-5 large transverse wrinklings which formed many discontinued shallow rugae. 2. The entire surface of anterior body was regularly arranged with the spines of which tips diverged into 3 to 4 points. They were densely packed in anterior mid-median portion of dorsal surface where appeared a few spines indented upto 5 points. Farther laterally and posteriorly from this portion, the pointed spines were more sparse and became single tipped and extended to anterior one-third of posterior body, 3. The posterior surface of oral sucker was armed with 50-60 spines having 2-3 tips and ventral sucker also covered with such spines. On anteriormost dorsal surface arranged 60-70 spade-shaped spines. The tribocytic organ was armed with many stout recurved pile-like spines arranged radially. 4. There were 3 types of sensory papillae. The ciliated knob-like (Type I) papillae were almost bilaterally symmetrical in ventral and dorsal surfaces of anterior body, and abundant especially aroundbases of oral and ventral suckers, tribocytic organ, and in lateral margins of anterior body. About 24 non-ciliated round swellings (Type II) were observed around each lip of oral and ventral suckers. The plate-like elevated papilla without cilium (Type III) was found to distribute only in posterior body. These 3 types of papillae seem to be tangoreceptive and/or rheoreceptive in function when their morphology and distributions are considered.

Background: Opioid delivered by epidural patient-controlled analgesia (PCA) is effective in relieving pain after surgery, but it is associated with side effects, such as nausea, vomiting, pruritus, respiratory depression, and urinary retention. The purpose of this study was to compare hydromorphone related side effects and the quality of analgesia when naloxone was added to epidural PCA regimen. Methods: Fifty-two thoracotomy patients with PCA were allocated blindly into two groups. Patients in group H (n = 26) received continuous epidural hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine; patients in group N (n = 26) received an epidural infusion containing naloxone ($2{\mu}g/ml$) and hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine. The basal rate of PCA was 4 ml/hr and the demand dose was 1.5 ml with a lockout time of 15 min. Pain intensity, sedation, pruritus, nausea and vomiting, respiratory depression were checked at 6, 12, 24 hours postoperatively. Results: The Visual Analog Scale (VAS) scores were significantly lower in group H than in group N. There were no significant differences in the overall incidence of pruritus, nausea and sedation between the two groups. Conclusions: Continuous epidural infusion of naloxone combined with hydromorpho-ne is not effective in reducing the incidence and severity of pruritus induced by epidural hydromorphone.

Parboiling, a popular technology used to protect rice from nutrient loss during milling and to increase the shelf-life of rice, was applied to barley kernels, and its effect on nutrient retention and chemical composition was evaluated. Before 36 days after ear emergence, barley kernels showed water content higher than 40%, and parboiling without presoaking resulted in at least 43% of gelatinization degree. This implies that soaking, an important step of parboiling, is dispensable for barley at milky stage. Parboiling did make little change in the appearance of the kernel after 31 days from ear emergence. Nonreducing sugars such as sucrose and raffinose remained unchanged while reducing sugars of barley was decreased by parboiling, with exception that maltose increased. Pearling led to decrease in crude protein, fat, fiber and minerals of barley sampled and parboiled on 36th day from ear emergence. Free sugars in the parboiled barley also was reduced with increasing pearling rate. Vitamin $B_1$ content of the parboiled barley was $260\;{\mu}g\;per\;100\;g$ as dry basis at 50% pearling rate, compared to $36\;{\mu}g$ for raw barley at same pearling rate. Thus parboiling appeared to be very effective in the retention of vitamin $B_1$ during pearling.

This experiment was carried out to find out the dormancy physiology, method of softening culture and evaluation of nutritional value of wild garlic, Ulrung-native Allium victorialis var. platyphyllum. In March, a new bulbs, the shoot and bulbs began to develop until the bulbs showed their complete dormant states in late August. The bulbs renewed to another one in every years. When shoots germinated about $1{\sim}2\;cm$ from mother bulbs, the soft tissues in the mother bublbs was degenerated and finally remained as only fiberous tissues unlike the other bulbaceous plants. There was a high inhibiting activities like ABA in the bulbs. This is believed that this inhibiting substance like ABA in the bulbs is related to the dormancy of wild garlic. Although the immatured bulbs, harvested at May and June, was treated with chilling for 90 days, it didn't germinate their shooting, but the matured bulbs, harvested at July and August, could germinate their shooting over 1 cm in 75 and 60 days chilling treatment, respectively. The shoot elongation was promoted by the longer chilling periods, the later harvesting day and the dark condition. The crude fiber content of leaf and stem increased at more expanded leaf and higher light intensity condition. Since the shoots, grown from germinating to leaf expanding time, had a good quality for food stuff and had less crude fibers, we supposed this period is to be most appropriate for harvesting time.

This study was conducted to analyze the relationship among climatic factors and radial growth of Pinus koraiensis in South Korea. To determine climate-growth relationships, cluster analysis was applied to group climatically similar surveyed regions, and dendroclimatological model was developed to predict radial growth for each climate group under the RCP 4.5 and RCP 8.5 scenarios for greenhouse gases. The dendroclimatological models were developed through climatic variables and standardized residual chronology for each climatic cluster of P. koraiensis. 2 to 4 climatic variables were used in the models ($R^2$ values between 0.35~0.49). For each of the climatic clusters for Pinus koraiensis, the growth simulations obtained from two RCP climate-change scenarios were used for growth prediction. The radial growth of the Clusters 2 and 3, which grow at high elevation, tend to increase. In contrast, Cluster 1, which grows at low elevation, tends to decrease with a large difference. Thus, the growth of Pinus koraiensis, which is a boreal species, could increase along with increasing temperature up to a certain point.

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.

Purpose: To analyze differences in the dose uniformity for the computed breast radiation therapy planning with tangential beam between conventional RT using wedge filter and FiF-IMRT using multileaf collimator based onsizes and volumes of breasts. Materials and Methods: Thirty breast cancer patients were classified according to the sizes and volumes of the breasts using Eclipse treatment planning system ($Varian^{TM}$, USA, V8.0). Conformity Index and Homogeneity Index were computed along with Dose Volume Histogram. Results: No differencein CI (${\pm}1.2%$) was observed. However, lower mean HI (1.67%) in FiF-IMRT was observed compared to that of the conventional RT. Statically significant (P<0.01) correlation was identified between the values of ${\Delta}HI$ (%) and physical parameters such as breast volumes and separations. Conclusion: Increase in breast volume and separation improves the dose uniformities in computed radiation therapy planning for FiF-IMRT. Physical dimension of the breast should be considered to optimize the compured radiation therapy planning.

Achievement profile by attribute in Korean students' mathematics was analyzed by applying cognitive diagnostic model, which is the newest measurement theory, to 2011 NAEA(National Assessment of Educational Assessment) results. The results are as follows. As the level of school is higher from 6th grade, 9th grade to 11th grade, the percentage of students mastering cognitive attribute 9(expressions using picture, table, graph, formula, symbol, writing, etc) drastically declined from 78%, 35% to 26%. It is necessary to have learning strategies to reinforce their abilities of expressing table, graph, etc. that higher graders in mathematics are more vulnerable to. Next, the property of mastering cognitive attributes according to gender, multi-cultural family was analyzed. In terms of mathematics, the percentage of girls mastering most of the attribute generally is higher than that of boys from 6th grade to 9th grade, however, boys show higher mastery in almost attributes than girls in the 11th grade. Compared to boys, the part where girls have the most trouble is attribute 9 in mathematics(expressions using picture, table, graph, formula, symbol, writing, etc). As international marriage, influx of foreign workers, etc. increase, the number of students from Korea's multi-cultural families is expected to be higher, therefore, identifying the characteristics of their educational achievement is significant in reinforcing Korea's basic achievement. In mathematics, gap of mastery level of attributes between multi-cultural group and ordinary group is more severe in higher grade and the type of multi-cultural group that needs supports for improving achievement most urgently changed in 6th grade, 9th grade and 11th grade respectively. In the 6th and 11th grade, migrant students from North Korea show the lowest level of mastering attributes, however, in the 9th grade, the mastery rate of immigrant students is lowest. Therefore, there is an implication that supporting plans for improving achievement of students from multi-cultural family should establish other strategies based on the characteristics of school level.
