Most of the North Korean defectors are the socially disadvantaged, and formed the lowest class in South Korean society. Their main objectives are to achieve economic wealth. In this process, North Korean defectors have often committed the crime or have been criminal victims. The purpose of this study was to propose the effective preventive measures after analyzing the actual situation of North Korean defectors in criminal behaviors and criminal damages. This research has studied of the literature on the criminal behavior and the criminal damage by North Korean defectors, utilized the relevant statistical data, cited the news for the relevant cases, and proposed the effective preventive measures of criminal behaviors and criminal damages of North Korean defectors by doing in-depth interviews with personal protection officer First, in order to prevent criminal activity by North Korean defectors, we should uplift the identity as the members of Korean society, systemize the initial adapt education, enlarge the employment protection and the resettlement helper system, manage North Korean defectors according to adaptive type, develop the network, establish the management department for the defectors, strengthen the training of prison inmates, and strengthen the management of unprotected people. Next, in order to prevent the criminal damages of North Korean refugees, we should manage vulnerable North Korean defectors effectively, maintain the liaison between the personal protection officer and North Korean defector, arrange the personal safety measures in advance when traveling abroad, enhance the legal education for usual living in Korean society, and perform the re-education for the female socialization.

Purpose: The purpose of this study is to help care workers to do their best as first respondents by analysing their recognition, knowledge, and self-efficacy on basic CPR (cardiopulmonary resuscitation) that is directly connected to the lives of patients and thus their education and methods can be improved for their positive basic lifesaving work. Method: For this purpose 360 structured questionnaires were used to the subjects in the eastern area of Jeonnam province from June 20 to July 4, 2011. Of these questionnaires 217 were used excluding 113 incomplete, 27 error, and 3 male ones. The collected data were analysed by the real number, the percentage, the average, the standard deviation, t-test, ANOVA, and Tukey with SPSS WIN 18.0. Results: 1. In the view of subjects, those aged over 51 accounted for 96(44.2%) as the majority, high school graduates, 95(43.8%), worked for 1 or more than 1 year-less than 2 years, 66(30.4%), experienced to see persons collapsed losing their consciousness, 46(21.2%), took the education, 184(85.7%), had 1 session of education, 80(43%), got the last education for 2 or more than 2 years 68(37%), and practiced through mannequin for the education aids, 86(46.7%). 2. There was significant difference in the view of recognition with the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.020), in the view of knowledge with academic background (p=.040) and the length of work, and in the view of self-efficacy with academic background (p=.002), the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.000). 3. There was significant difference in the session of education (p=.000), last education (p=.025) and education aids for basic CPR. Self-efficacy had significant difference according to the session of education for basic CPR (p=.001) and the time of education (p=.000). 4. There was correlation between recognition and self-efficacy (r=.41). The higher the recognition is, the better the self-efficacy improves. However the correlation between knowledge and self-efficacy was so low that the former did not have influence on self-efficacy. Conclusions: It needs to offer education to the lifesaving workers based on their experiences. If there is education more than 2 sessions in a year with mannequin and the simulation providing sufficient hours, care workers' recognition would be increased resulting in higher self-efficacy and thus they could keep the role of active lifesaving worker at the first practical site.

The purpose of this study was to find out inservice teachers' teaching skills and relevant educational settings that could be applied to an instruction of problem-based learning (PBL). Participants have been instructed PBL teacher training programs and applied PBL into teaching and learning process. Three elementary teachers were selected to participate in the study, and data were collected with semi-structured interviews. The interviews of the teachers in relation to PBL were analyzed by two main topics: (1) the teachers' teaching skills required in PBL and (2) the educational settings in implementing PBL. The results are as follows: First, there is a difficulty involved in the implementation of PBL in that its preparation and teaching process are different from the traditional teaching methodology. However, as a helper who guides the students to self-directed learning in the free and permissible learning environment in which students are motivated to develop their potential effectively, the teachers are to invest their time consistently and to put their efforts into making an effective class in the entire process of PBL. Second, as a method to apply the problem-based learning to the education settings, the teachers must spread the awareness of PBL to fellow teachers, students, their parents and the administrators in education and form the community of the teachers. Most importantly, when the teachers apply PBL in the directly, from the joy of witnessing the changes in the students, they will choose to adopt PBL.

The purspoe of this study is to identify the socialization level of household work of the employed and unemployed housewives and it's related variables in order to provide some fundamental information for the rational and effective performation of the household task. For the purpose of this study, 700 questionnaire were distributed to the employed and unemployed wives who lived in Seoul. The data were analyed by the Frequency distribution, Percentile, t-test, F-test, Duncan's Multiple Range Test, and Multiple Regression Analysis. The main results were as follows : (1) Socialization level of household work of the employed wives was a little below medium point. When the household work was devided into three subdomains, in the domain of food and shelter, the socialization level was far below medium point. In the domain of clothes, the socialization level was a little higher than medium point. Socialization level of household work of the unemployed wives far below average. When the household work was devided into three sudbomains, in the domain of food, clothes and shelter, the socialization level was far below average, too. Socialization level of household work was significantly different according to the employment. (2) Among the background veriables, family income, household work helper, and frequency of leisure activities have a significant influence on the socialization level of the employed wives. Duration of marriage, housewife's education level and house income have a important effect on the socialization level of the unemployed wives background. (3) Among the background variabels of household work, performing competence of household work is powerful effect on the socialization level of the employed wives. And as for the unemployed wives, performing competence of household task and recognition of the velue of household work are significant variables. (4) The psychological variable such as sex-role attitude gave no noticeable influence on the socialization level of employed and unemployed wives. (5) In conclusion, classifing the variances influencing on the socialization level of household work in a measure of respcetive effect, it appears to be performing competence of household task, frequency of leisure activities, house income, sex-role attitued and educational level in the order of their influences for the employed wives. And as for the unemployed wives, it seems to be house income, educational level, performing competence of household work and frequency of leisure activities. To the two sides, the rate of explanation is shown at 35%.

The violent crime has increased dramatically in our society. This is because our society has to change quickly. Strong police force, but this is not enough to solve the crime. And there are a lot of police to investigate the situation difficult to go out to the crime scene. So inevitably increase in the risk of crime. Researchers have conducted a number of studies to solve this problem. However, the proposed study how realistic are many points still lacking. herefore, we to take advantage of smartphones and high-speed Internet access technology to provide security services using the push service for rapid identification and crime situation in this study. Therefore, we would like to provide rapid service to identify criminal security situation using smart-phone app and push services on the high speed internet environments. The proposed system is to record the voice information received from the smart phone near the user presses the hot key is set in advance in real-time, and stores the audio information stored in the LBS information to the server through the authentication procedure. And the server uses the stored voice data and LBS Push service information to inform their families. We have completed the design of the proposed system. And it has implemented a smart phone app, the user authentication server. And using the state in which the push service from the authentication server by transmitting a message to a user to inform a family. But more must examine whether the proposed research is relevant in future studies.

Progesterone is necessary for successful pregnancy and had immunosuppressive properties. Peripheral blood mononuclear cells (PBMC) from many women with unexplained recurrent spontaneous abortion responded to trophoblast extract in vitro by prolifertion and releasing soluble, heat-labile factors that are toxic to mouse embryos (embryotoxic factors). Accumulating evidence suggests that T Helper (Th)-1 type immunity to trophoblast is correlated with embryotoxic factor production and is associated with pregnancy loss, while Th2-type immunity is associated with successful gestation. The objective of this study was to determine whether progesterone can inhibit Th1-type cytokine secretion (IFN-${\gamma}$, TNF-${\alpha}$) by trophoblast-activated peripheral blood mononuclear cells from 23 nonpregnant women (age 25-35) with unexplained recurrent abortion (median 5, range 3 to 15)who otherwise produce embryotoxic factors in response to trophoblast. We also determined whether progesterone affected Th2-type cytokines (IL-4, IL-10) in this system in vitro and if IL-10 (1,500 pg/mL) could inhibit Th1-type immunity to trophoblast. IFN-${\gamma}$ was detected in 17 of 23 (74%) trophoblast stimulated PBMC culture supernatants ($77.94{\pm}23.79$ pg/mL) containing embryotoxic activity. TNF-${\alpha}$ was detected in 19 (83%) of these same supernatants ($703.15{\pm}131.36$ pg/mL). In contrast, none of the supernatants contained detectable levels of IL-4 or IL-10. Progesterone ($10^{-5}$, $10^{-7}$, $10^{-9}$M) inhibited Th1-type immunity in a dose dependent manner, but had no effect on Th2-type cytokine secretion. The inhibitory effects of progesterone were abrogated with RU486, but did not affect Th2-type cytokine secretion in trophoblast-activated cell cultures. IL-10, like progesterone also inhibited Th1-type cytokine secretion but had no effect on Th2-type cytokines. These data suggest that therapies designed to suppress Th1-type cytokine secretion in women with recurrent abortion who have evidence of Th1-type immunity to trophoblast may be efficacious in preventing pregnancy loss and should be tested in appropriately designed clinical trials.

Background: Ulcerative colitis (UC) is the large intestine disease that results in chronic inflammation and ulcers in the colon. Rg3-enriched Korean Red Ginseng extract (Rg3-RGE) is known for its pharmacological activities. Persicaria tinctoria (PT) is also used in the treatment of various inflammatory diseases. The aim of this study is to investigate the attenuating effects of Rg3-RGE with PT on oxazolone (OXA)-induced UC in mice. Methods: A total of six groups of mice including control group, OXA (as model group, 1.5%) group, sulfasalazine (75 mg/kg) group, Rg3-RGE (20 mg/kg) group, PT (300 mg/kg) group, and Rg3-RGE (10 mg/kg) with PT (150 mg/kg) group. Data on the colon length, body weight, disease activity index (DAI), histological changes, nitric oxide (NO) assay, Real-time PCR of inflammatory factors, ELISA of inflammatory factors, Western blot, and flow cytometry analysis were obtained. Results: Overall, the combination treatment of Rg3-RGE and PT significantly improved the colon length and body weight and decreased the DAI in mice compared with the treatment with OXA. Additionally, the histological injury was also reduced by the combination treatment. Moreover, the NO production level and inflammatory mediators and cytokines were significantly downregulated in the Rg3-RGE with the PT group compared with the model group. Also, NLR family pyrin domain containing 3 (NLRP3) inflammasome and nuclear factor kappa B (NF-𝛋B) were suppressed in the combination treatment group compared with the OXA group. Furthermore, the number of immune cell subtypes of CD4⁺ T-helper cells, CD19⁺ B-cells, and CD4⁺ and CD25⁺ regulatory T-cells (Tregs) was improved in the Rg3-RGE with the PT group compared with the OXA group. Conclusion: Overall, the mixture of Rg3-RGE and PT is an effective therapeutic treatment for UC.

Objectives : A traditional herbal prescription, Kyung-Ok-Ko (KOK), has long been used in oriental medicine as an invigorant for age-related diseases, such as amnesia and stroke. However, the beneficial value of KOK for immune responses is largely unknown. Based on the above mentioned effects of KOK, other previous reports, and its use in traditional medicine, we hypothesized that KOK displays beneficial effects against methotrexate (MTX)-induced immune suppression. Methods : We investigated the effects of KOK (0.6 g/kg/day, oral (p.o.)) on deteriorated immunity caused by MTX (2 mg/kg/day, p.o.) in an immune suppression mouse model. MTX was fed to mice once a day for 7 days. After the immune responses of the mice deteriorated by MTX treatment, KOK in water was fed to the mice once a day for 14 days. We then measured the expression levels of various cytokines, such as T helper cell (Th1, Th2) cytokines, and the number of immune cells, such as spleen T cells, B cells, and macrophages. Results : The data showed that MTX decreased Th1 profiles (interferon $(IFN)-{\gamma}$, interleukin (IL)-2, IL-12) and the number of immune cells, and increased Th2 profiles (IL-4, IL-5, IL-13), which were normalized significantly by post-administration of KOK. However, there was no significant difference in body-weight gain between MTX- and KOK-treated mice. Conclusion : These results indicate that KOK has immune-enhancing functions and reduces immunotoxicity of MTX, suggesting that supplementation with KOK will improve immune responses clinically and be useful for the prevention of immune-related diseases.

This study examined the prevalence of and factors associated with unmet care need among community-dwelling middle-aged and older people in Korea. Data were from the 2006 Korean Longitudinal Study on Ageing (KLoSA), a national survey of 10,254 non-institutionalized adults aged 45 or older. Having unmet care needs was defined as needing personal assistance with activities of daily living (ADL) or instrumental activities of daily living (IADL) but having no available helper. Weighted logistic regressions were fitted to examine factors associated with unmet care needs. Overall, 7.3%, 14.5%, and 41.8% of subjects among the middle-aged, younger old, and older old, respectively, reported care needs of these, 34%, 33%,and 24% had unmet needs. Factors associated with unmet needs differed among the three groups: Education and income level were negatively associated with unmet needs among the middle-aged, but living alone was the only factor positively associated with unmet needs in both the younger and older old. The prevalence of and factors associated with unmet care needs differ by life-stage. Needed are home- and community-based care and services to meet the need for personal assistance among the elderly living alone in a community.

Purpose: The purpose of this study was to survey the knowledge and needs of hospice for inpatients' family. Methods: This study was carried out with 277 inpatients' families at J General Hospital located in J city, Korea during the period from March to May, 2004. The data were collected through a self-reporting questionnaire constructed by the authors. The data were analyzed by descriptive statistics and $x^2-test$ with SPSSWIN 10.0. Results: 83.8% of the respondents heard about hospice mostly through mass communication. 76.9% of the respondents recognized hospice to be helpful and to provide comfort during the remainder of life and to confront the moment of death. Most of the respondents responded positively to the necessity of hospice service, and would receive hospice if necessary. 76.5% of them would consider arranging preparation for death if he/she were to be diagnosed with a terminal illness. 63.9% of the respondents wanted only to be with their family members, 31.4% wanted both the family and hospice members at the moment of death. They named the best helper among the hospice members to be the nurse. 81.6% of the respondents wanted a hospice institution to be established, 23.8% of them report that the most adequate hospice management institution would be the hospice ward in hospital. Conclusion: Consequently, most respondents wanted hospice services. So Korean society is in need of developing adequate teaching and care programs for hospice according to local needs.
