Chinese American Writer, Ha Jin has been writing exclusively about the life in his native Communist China. His stories and poems are almost all about the Chinese people so far. In addition, the distinctive Chinese flavour and the inexorably repressive image of China in his works present an 'Other' to the American culture. Such kind of Chineseness can also be found in Ha Jin's works and his career as a writer. The continued demand for knowledge of China, which is created by China's increasingly important role in the globalized economy, sustains the country's position as an Other for America. In his early four novels, Ha Jin portrays a totally repressive image of Communist China, an image of which functions perfectly as a form of otherness for his American readers. In Ha Jin's portrayal, the Chinese masses are subjected to the Communist authority through its bureaucracy and state-economy mechanism, as well as through the godlike image of Mao Zedong. They are to follow the Communist conscience and subscribe to unity-in-difference. Deviation from the one-party rule is intolerable. In each of the novels, Ha Jin presents a specific system of repression. In In the Pond, confrontation against Party authority is contained by a process of complicity. In Waiting, the Party's power is upheld through a system of surveillance in which people act as agents, resulting in a web of power which paralyses love. The Crazed illustrates a play of power by Party officials which, against the backdrop of the Tiananmen Square Massacre, is full of craze itself, driving people either out of sanity or out of the country. War Trash exposes the Communist power's repression to the extreme by presenting a case of dishonour in those whose life is debased as trash by the Party. The repressive image of China produced in these stories, which span over half a century, makes Ha Jin's China a perfect Other for the West. To sum up, Ha Jin's novels construct a repressive image of China. In his novels, Ha Jin exposes the working of repression in particular systems. Through these systems, he problematizes the notion of personal autonomy for Chinese people and proposes for his western/American readers a solution which eventually turns into a re-presentation of American hegemony.

Objective: This study aims to assess the following issues - acquisition level in terms of the information on frequently used drugs of youth, access paths for the information, actual status of the use of drugs frequently used by youth, types of the used drugs, drug abuse among youth, and the consequent drawbacks. This study also takes aims at suggestion of correct role of pharmacists in consideration of drug abuse among youth. Methods: During the period from August 1, 2011 to October 31, 2012, a research design and a question development have been conducted. To the students of the schools that were randomly selected (elementary school's N=99, middle school's N=106, high school's N=115 and university's N=115), it was asked to complete given questionnaire from August 1, 2012 to August 31, 2012. During the period from September 1, 2012 to October 30, 2012, the questionnaires were collected back and the analysis and evaluation of them were carried out. Results: Drugs known to the respondents were a total of 115 different medicines and most of the drugs belonged to over-the-counter drugs. The most well known drug was pain reliever and the second most familiar drug was wound ointment. Most of the respondents found the drugs through direct use and advertisement. In everyday life, more than half of the respondents were using over-the-counter drugs as well as health supplements. The most commonly used drug was analgesic drug. It was showed that the respondents also frequently used the drugs for improving their grades and appearances. It was shown that among the cases of drug use, there were also the cases of misuse and abuse of drugs for the respondents or people around them. Reliability of pharmacists was shown to be high and many students were also satisfied with the pharmacists' guidance for medication. Conclusion: Currently many students are using different kinds of drug in daily life, and there is a possibility that the risk of misuse and abuse of drugs will be increased. Those age groups can easily engage in bad habit of drug use. Thus, promotion on accurate drug information has to be strengthened, and pharmacists are required to conduct correct guidance for drug user's medication in terms of use amount, usage, interactions among different drugs, and potential risks.

Middle and high school girl students' menstruation characteristics, appearance of menstruation dysmenorrhea, and coping with the menstruation dysmenorrhea were examined in order to give information in instructing girl students about menstruation dysmenorrhea, in delivering health education in the school, and establishing health policy. 970 girl students in middle and high schools in Cheju-do were selected and surveyed using the questionnaire the author developed based on the previous studies. The findings are as follows. First, the age of first menstruation was average $12.9{\pm}1.22$ years. The younger they were, the earlier their first menstruation came. The most common menstrual cycle was such one that continuously irregular from the beginning or that regular and irregular cycle run together. The first irregular menstrual cycle changed regular one within 1 or 2 years. Most of the respondents had normal menstrual cycle of $21{\sim}35$ days and menstruation period of $3{\sim}8$ days. Second, symptom of menstruation dysmenorrhea was orderly; hurt in the underbelly, tired, hurt in the waist, and headache. It was higher with high school students than middle school students. For the most part, time of heavy menstruation dysmenorrhea was the 2nd day after menstruation starts and period of menstruation dysmenorrhea was 2 days. More than the half of the respondents felt that the present menstruation dysmenorrhea was similar with the first one and they felt not comport in daily life due to menstruation dysmenorrhea, and 'hard to live a normal life' was higher with the high school girl students than with the middle school students. Third, how to cope with menstruation dysmenorrhea was enough sleep, relax and rest, taking a hot water shower, listening to music or watching a movie, taking medicine, and doing excercise. Few of the respondents have ever visited a doctor due to menstruation dysmenorrhea, and the reason was mostly irregular menstruation and heavy dysmenorrhea. Forth, when they took medicine due to menstruation dysmenorrhea, they gathered information on the medicine from family members and friends, while extremely low from a pharmacist or a doctor. The most of them have ever took medicine during menstruation once and took standard dose. While excess dosage was higher with high school students than with middle school students. From these findings, a good many girls are experiencing menstruation dysmenorrhea since their first menstruation. To discover early the severely abnormal findings and to treat, more interest from home and school, counseling and sexual education on time, and expert's diagnosis are necessary. Rather than unconditionally taking pain-relievers which can plainly solve the pain, continuous health education at home and in the school should be carried on for the girls to practice proper measures one think effective or an expert recommends.

This experiment was conducted to investigate the effects on plant growth, soil chemical properties and microbial flora with microbial fertilizer to chinese cabbage cultivation. The plant growth was promoted and the yield increased by application of Tian Li Bao(TLB) microbial fertilizer as compared with the control. However, yield a littler decreased in case of the reduced amount of urea application as a top dressing and half of compost chicken manure as a basial fertilizer even if treated with TLB microbial fertilizer. Organic matter and total nitrogen contents decreased as compared to those in the control, and total nitrogen ranged in 0.76~1.44% in the treatments at harvesting time, and decreased with application of TLB microbial fertilizer compared to that of the control. The available phosphorus content in the field before experiment was 559ppm, but it was 755ppm and 653 in the control and treatments at harvesting time, respectively. Therefore, it was shown that phosphorus content in the treatment was lower than that of the control. On the other hand, total nitrogen, phosphorous and K ranged from 2.62 to 2.94%, from 1.48 to 1.55% and from 3.60 to 4.38% in plants after harvest, respectively. There were no significant differences among the treatments. For the soil microbial flora, the population of bacteria in the treatments decreased with application of microbial fertilizer as compared with the control over all cultivation periods. It was shown that the population of pseudomonas spp. was over 3 times higher than that of the control after harvesting. The population of actinomycetes didn't show difference among the treatments, but high density of fungi after harvesting were observed in the treatments.

Mobilization of storage lipids is critical for the germination of oil seeds, as they supply carbon and energy until photosynthesis commences in cotyledons. In this study, we determined the levels of plant carnitine and associated changes in these levels from seed germination to cotyledon senescence. We also examined changes in the content of unsaturated fatty acids throughout seedling development. Carnitine levels peaked on day 3 at 14.5 nM in cotyledons and decreased sharply to 7.2 nM on day 4. On development day 3 carnitine levels were maintained at around 3 nM until day 7. The unsaturated fatty acid content dropped by half at the same time as carnitine peaked (day-3), and storage lipids were almost depleted by day 5. Thereafter, carnitine was hardly detected until the second stage of cotyledon senescence, at which stage the carnitine content was 6.8 nM, similar to that on day 4 at the time of fatty acid depletion in the cotyledons. Unsaturated fatty acids levels remained constant in green cotyledons but slightly increased in the senescing cotyledons. The latter can be explained by intracellular breakdown of membrane lipids. This is the first such discovery in developing cotyledons and may offer clues regarding other roles of the acetyl unit transport system in plants. The expression of BOU was closely associated with carnitine metabolism during seed germination and cotyledon development. The results provide support for the possibility of carbon re-routing during the glyoxylate cycle in the supply of energy for early germination and development.

Purpose Quality control of instrument takes up a large part in the Radioimmunoassays. The gamma-ray instrument, which is one of the important instruments in the laboratory, observes the condition and performance of instrument and performs quality control of the instrument by measuring the Normalization, Calibration, Background and etc. However, there are some automation instruments which can't measure the counting efficiency of gamma-ray meters, resulting in insufficient management in terms of performance evaluation of gamma-ray meters. Therefore, the purpose of this paper is to manage the quality control continuously and regularly by suggesting how to measure the counting efficiency of gamma-ray instruments. Materials and Methods In case of a comparative measurement method to a gamma-ray instrument dedicated to nuclear medical examination, the CPM and counting efficiency can be obtained after the measurement of normalization by inserting the I-125 $200{\mu}L$(CPM 50,000~500,000) into the test tube. With this CPM and counting efficiency values, it's possible to calculate the measurement of the DPM value and count the CPM from the automation instrument from the same source, and enter the DPM to calculate the counting efficiency using a comparative measurement method. Another method is to calculate the counting efficiency by estimating the half life using the radiation source information of the tracer in B test reagents of company A. Results According to the calculation formula using the DPM obtained by counting the normalization of gamma-ray meters, the detection efficiency was 75.16% for Detector 1, 76.88% for Detector 2, 77.13% for Detector 3, 75.36% for Detector 4 and 73.2% for Detector 5 respectively. Using another calculation formula estimated from the shelf life, the data of the detection efficiency from Detector 1 to Detector 5 were 74.9%, 75.1%, 76.5%, 74.9% and 73.2% respectively. Conclusion Although the accuracy of counting efficiencies of both methods are insufficient, this is considered to be useful for ongoing management of quality control if counting efficiency is managed after setting the acceptable ranges. For example, if the measurement efficiency is set to 70% or higher, the allowed %difference between measurements is within 3% and the %difference with the detector wall is set within 5%.

Objectives: The purpose of this study is to empirically verify the difference between traditional gender role attitude and realistic dual earner attitude. Most preceding studies analyzed gender role attitude by summated rating scale while few studies have been conducted on the difference between traditional gender role attitude and dual earner attitude. Method: By using the 9th Korea Welfare Panel Data (year 2014), this study extracted households of married couples and with children in working age (18 through 64 years of age) who are the main subjects in work-family relationship. First, this study classified traditional group and modern group in their gender role attitude and passive group and active group in their dual earner attitude and by crossing these attitudes, drew out 4 gender role/dual earner attitudes. For analysis, this study investigated frequency of attitude types through descriptive statistics. By conducting ANOVA, study verified if there are significant differences in the satisfaction with family relationship depending on the types of gender role/dual earner attitudes. Lastly, study examined the effect of socio-economic status and demographic characteristics on the types of gender role/dual earner attitudes by conducting multi-nominal logistic regression analysis. Results: As the result of analysis, first, half of respondents belonged to 'equal-role-oriented type' who has modern gender role attitude and active dual earner attitude. However, there were not a few 'dual-earner-avoiding type' who has modern gender role attitude but passive dual earner attitude and 'incongruous attitude type' who has traditional gender role attitude but active dual earner attitude. Next, 'incongruous attitude type' had significantly low level of satisfaction with overall family life, relationship with spouse and relationship with children than other attitude types. Lastly, those whose incomes belong to poor strata, those who are high school graduates and lower, males and those who are over the age of 60 had significantly higher probability of belonging to 'incongruous attitude type.' Conclusion: The results of analysis demonstrate that the difference between gender role attitude and dual earner attitude is an important matter and since 'incongruous attitude type' exhibits low level of satisfaction with family relationship, scrupulous policy approaches are required for those who have high possibility of belonging to 'incongruous attitude type.'

This study investigated whether or not the major bioactive compounds of Noni (Morinda citrifolia) are involved in anti-inflammatory activity through the JAK/STAT upper signaling pathway in RAW 264.7 cells. The experimental results show that the M. citrifolia ethyl acetate fraction (Mc-EtOAc) obtained by sequential fractionation with organic solvents from the plant's dried fruits exhibits the highest antioxidant activity. In addition, the cytoprotective effects of Mc-EtOAc against H₂O₂-induced oxidative stress in the RAW 264.7 cells suppressed cytotoxicity in a dose-dependent manner. The group pretreated with Mc-EtOAc at a concentration of 240 ㎍/ml showed higher cell viability of 84.5%, compared to 71.6% in the LPS-treated group, and LPS-induced NO production decreased to half the amount in the positive control group. Mc-EtOAc treatment also led to a significant dose-dependent reduction in iNOS expression. Although COX-2 expression was increased by 300% following LPS induction, it was significantly decreased in a dose-dependent manner by pretreatment with Mc-EtOAc at concentrations of 120 and 240 ㎍/ml. An inhibition of the mRNA expression of pro-inflammatory cytokines IL-1β and TNF-α was observed. The investigation also revealed that the phosphorylation levels of pJAK1 and pSTAT3 in LPS-induced RAW 264.7 cells were significantly reduced by Mc-EtOAc treatment.

The objective of this study was to investigate whether betulinic acid can inhibit the activities of carbohydrate-digesting enzymes and reduce postprandial hyperglycemia in mice with streptozotocin-induced diabetes. Our results revealed that betulinic acid has potent inhibitory effects on α-glucosidase and α-amylase activities. The half-maximal inhibitory concentrations (IC₅₀) of betulinic acid were 12.83±6.81 and 18.32±3.24 μM for α-glucosidase and α-amylase, respectively. This result indicates lower IC₅₀ values and higher inhibitory activities than those of acarbose, an oral hypoglycemic drug. The increase in postprandial blood glucose levels was significantly suppressed in the betulinic acid group than in the control group of diabetic and normal mice. Postprandial blood glucose levels were 23.22±1.1, 24.38±1.31, and 21.05±1.36 μM in the betulinic acid group compared to 24.64±1.7, 27.22±1.58, and 26.36±1.40 μM in the control group of diabetic mice at 30, 60 and 120 min, respectively. The area under the curve also significantly decreased with the administration of betulinic acid in diabetic mice, however, it did not decrease more than that after acarbose administration. Our results showed that betulinic acid may be a potent inhibitor of carbohydrate-digesting enzymes and ameliorate postprandial hyperglycemia in diabetic mice.
