This paper reports the results of a systematic review (SR) and meta-analysis research to compare the effect of Kangaroo care, targeting mothers and premature infants. A randomized clinical trial study was performed until February 2015. The domestic literature contained the non-randomized clinical trial research without restriction according to the level of the study design. A search of the Ovid-Medline, CINAHL, PubMed and KoreaMed, the National Library of KOREA, the National Assembly Library, NDSL, KISS and RISS. Through the KMbase we searched and combined the main term ((kangaroo OR KC OR skin-to-skin) AND (care OR contact)) AND (infant OR preterm OR Low Birth Weight OR LBW), ((kangaroo OR kangaroo OR kangaroo) AND (care OR nursing care OR management OR skin contact)) was made; these were all combined with a keywords search through the selection process. They were excluded in the final 25 studies (n=3051). A methodology checklist for randomized controlled trials (RCTs) designed by SIGN (Scottish Intercollegiate Guidelines Network) was utilized to assess the risk of bias. The overall risk of bias was regarded as low. In 16 studies that were evaluated as a grade of "++", 9 studies were evaluated as a grade of "+". As a result of meta-analysis, kangaroo care regarding the effects of premature mortality, severe infection/sepsis had an insignificant effect. Hyperthermia incidence, growth and development (height and weight), mother-infant attachment, hypothermia incidence, length of hospital days, breast feeding rate, sleeping, anxiety, confidence, and gratification of mothering role were considered significant. In satisfaction of the role performance, depression and stress presented contradictory research results for individual studies showing overall significant difference. This study has some limitations due to the few RCTs comparing kangaroo care in the country. Therefore, further RCTs comparing kangaroo care should be conducted.
The purpose of this study was to verify the influence of musical activities on social and emotional behavior of infants, through providing musical activities to the infants who were cared in a nursery and observing the interactions between peer group, or a therapist and an infant derived during them. The subject is 24 infants who are under 2 years of age(25~36months) at two nurseries located in Bundang area, and 13 infants among them are randomly assigned as study group and 11 infants as control group. Pretest and posttest about social and emotional behavior are performed, and ITSEA developed by Brggs-Gowan and Carter(2001) and amended by Shin Ji Yeon(2004) was used as an evaluation tool. Infants' changes of interaction behaviors during musical play were also analyzed quantitatively and qualitatively, and for the analysis, infant's social play behavior examination tool developed by Holloway and Reichhart-Erickson(1988) was adopted. Based on time sampling method, each item of this tool was evaluated. Each session was performed for 15 minutes, and 60 times of analysis about interactions per session was conducted at every 15 seconds. The analysis result was showed with a table and a graph, and described qualitatively about behavior changes. When compared social and emotional positive behavior average figures and negative behavior average figures between study group and control group, this study showed that the positive behavior figure of study group was increased and the negative behavior figure was decreased. While concentration and empathy among positive behaviors increased meaningfully, aggression, defiance, separation anxiety and rejection to new things among negative activities also decreased meaningfully. The conclusion of this study is as follows. First, interactions with peers or a therapist based on music and musical experience make an effect on strengthening positive behavior among social and emotional behavior and decreasing negative behavior. Second, music has influence on negative behaviors more than positive behaviors of an infant, and produces a good effect on sub behaviors of negative behaviors specially.

In this study, the anticancer activity of the water extract at $100^{\circ}C$ was compared to that of the callus extracts via a ultrasonification extraction process. All the extracts were utilized to evaluate cytotoxicity, antioxidant and immune activities. The callus extracted via ultrasonification extraction showed relatively low cytotoxicity on normal human cell lines, HEK293 and HEL299, showing 13.17% and 21.78%, respectively. The callus extract has 59.82% which was similar to 61.70% for water extracts. It was also found that callus extract yielded higher nitric oxide secretion form macrophage than other extracts. The growths of both human stomach adenocarcinoma (AGS) cell and human lung carcinoma (A549) were inhibited up to 70% by adding 1.0 mg/mL of the callus extracts with ultrasonification extraction. This inhibition ratio (70%) was almost close to that of water extract. Human hepatoma carcinoma (HEP3B) cell growth was most significantly inhibited up to 75% by adding 1.0 mg/mL of callus extracts, and its selectivity was highest compared to other extracts. It indicates that the callus extracts could selectively inhibit growth of digestive system-related cancer cells. It can be also concluded from the results of this study that the callus extracts associated with ultrasonification extraction process have the potential for anticancer activity.
The summary of the case is as follows: a Korean passenger booked and purchased a business class ticket from Air France that was scheduled to depart from Paris and arrive in Seoul. When the passenger arrived at the check-in counter, he was told that all business class seats were occupied. It was because the flight was overbooked by Air France. The passenger cancelled the Air France flight and took another air carrier. After arriving in Korea, he brought suit against Air France for damages. The purpose of this article is to discuss the governing law when interpreting the contract of international air carriage in accordance with the Korean Private International Act (2001) and to analyze air carrier's civil liability for the bumped passenger in the overbooking case. If the parties have not chosen the applicable law the contract shall be governed by the law of the habitual residence of the consumer in the following situations: prior to the conclusion of the contract, the opposite party of the consumer conducted solicitation of transactions and other occupational or business activities by an advertisement in that country or conducted solicitation of transactions and other occupational or business activities by an advertisement into that country from the areas outside that country and the consumer took all the steps necessary for the conclusion of the contract in that country or in case the opposite party of the consumer received an order of the consumer in that country [Article 27 (1), (2) of the Private International Act]. Since the contract of international carriage falls into the consumer contract, the Supreme Court viewed that the governing law of the contract in this case would be the law of the habitual residence of the consumer (Supreme Court Decision 2013Da8410 decided on Aug. 28, 2014). This interpretation differs from the article 5 (4) of Rome Convention(80/934/EEC) which declares that the consumer contract article shall not apply to neither a contract of carriage nor a contract for the supply of services where the services are to be supplied to the consumer exclusively in a country other than that in which he has his habitual residence. Even though overbooking can be considered as a common industry practice, an air carrier must burden civil liability in case of breach of contract for the involuntary bumped passenger(Seoul Central District Court Decision 2014Na48391 decided on Jan. 29, 2015). In case of involuntary bumping, an air carrier must offer re-routing to passenger's final destination by an alternative flight. If an air carrier fails to effect performance in accordance with the tenor and purport of the obligation, the involuntary bumped passenger may claim damages(Article 390 of the Civil Code).

AOAC Mouse Bioassay Analysis (MBA) has been the gold standard for the analysis of paralytic shellfish poisoning toxin (PSP toxin) for more than 50 years. However, this method has inaccurate limit of quantification and cannot be used to determine toxic profiles. An HPLC method (PCOX) was optimized for Korean shellfish to establish an alternative or supplementary method for PSP analysis and was intended to be used for the official monitoring and regulation of food. The recovery rate of the PCOX method was 83.5-112.1% and the limit of quantification for total toxin was about $8.6{\mu}g$/100 g. A long-term comparison study showed a good correlation of the PCOX results with the AOAC MBA results: the correlation factors were 0.9534 and 0.9109 for oyster and mussel matrices, respectively. The PCOX method may be used as an alternative or supplementary method for AOAC MBA to monitor the occurrence of PSP and to analyze PSP toxin profile in oysters and mussels.

Purpose : We aimed to ascertain whether lumbar punctures should be done to prove febrile seizure, and to study what conditions can delay or abolish lumbar puncture. Methods : This retrospective study was done for four years, from January, 1996 to December, 1999. The subjects were the patients who visited Masan Samsung Hospital for the first convulsion with fever, and whose age ranged from 1-month to 5-years old. The total number of patients was 197. We investigated the rate of meningitis, which was classified by age, season, convulsion type, associated symptoms, and results of blood test. All data were tested chi-square. Results : The diagnosis rate of meningitis among all 197 patients was 7.6%, and of these only one patient was proved to have bacterial meningitis. The rate was high in the young(below 6 month), in males and in summer and autumn. Although the general appearance was good after resolution of the fever, the rate of meningitis was 6.5%. Patients with nausea and vomiting totalled 11%; 9.1% of them were diagnosed with meningitis. The diagnosis rate of meningitis in cases in which additional seizures took place were 33.3%. Conclusion : The ultimate goal of lumbar punctures in seizure patients with accompanying fever is to rule out bacterial meningitis, which, has been demonstrated to be rare. So we think that lumbar puncture can be postponed by close observation of pediatrics specialists and skilled nurses.
In this chapter, we summarize the results on the optimal location selection and present limitation and direction of research. In order to reach the objective, this study selected and tested the interaction model which obtains the value of co-ordinates on location selection through the optimization technique. This study used the original variables in the model, but the results indicated that there is difference in reality. In order to overcome this difference, this study peformed market survey and found the new variables (first data such as price, quality and assortment of goods, and the second data such as aggregate area, and area of shop, and the number of cars in the parking lot). Then this study determined an optimal variable by empirical analysis which compares an actual value of market share in 1988 with the market share yielded in the model. However, this study found the market share in each variables does not reflect a reality due to an assumption of λ-value in the model. In order to improve this, this study performed a sensitivity analysis which adds the λ value from 1.0 to 2.9 marginally. The analyzed result indicated the highest significance with the market share ratio in 1998 at λ of 1.0. Applying the weighted value to a variable from each of the first data and second data yielded the results that more variables from the first data coincided with the realistic rank on sales. Although this study have some limits and improvements, if a marketer uses this extended model, more significant results will be produced.
Purpose: SLE (systemic lupus erythematosus) is an inflammatory autoimmune disease, characterized by various autoantibody. The detection of Anti double-stranded DNA (Anti-ds DNA) is important in the diagnostics of SLE, and include the American College of Rheumatology (ACR) diagnostic criteria for SLE. Also SLE disease activity and correlativity with the level Anti-ds DNA antibody have been reported and Anti-ds DNA antibody quantitative test is very useful for tracing before and after SLE treatment. When These Anti-ds DNA antibody test (Farr assay: $^{125}I$ labeled ds-DNA and bound Anti-ds DNA antibodies complex in serum is precipitated by ammonium sulfate and used to centrifugation, measured it) inhaled supernatant after centrifugation, a lipemic specimen does not facilitate the formation of precipitate and also occurs situation was inhaled with precipitate. To solve these problems, The Influence of the degree of lipemic specimen was evaluated. Materials and Methods: September 2012 to February 2013, We selected lipemic samples (n=81) of specimen commissioned by Anti-ds DNA antibody test. Lipemic samples were done pre-treatment (high-speed centrifugation: 14,000 rpm 5 mins) used a micro-centrifuge (Eppendorf Model 5415D). At the same time lipemic specimen and pre-treatment samples were performed Anti-ds DNA antibody test (Anti-ds DNA kit, Trinity Biotech, Ireland). Statistical analysis were analyzed Pearson's correlation coefficients and regression and paired t-test, and Difference (%). Results: Experimental group 1 (Lipemic Specimen Anti-ds DNA Ab concentration ${\leq}7IU/mL$) at y=0.368X+4.732, $R^2=0.023$, Pearson's correlation coefficient was 0.154, paired t-test (P=0.003), Difference (%) mean 65.7 and showed a statistically significant difference. Experimental group 2 (Lipemic Specimen Anti-ds DNA Ab concentration ${\geq}8IU/mL$) at y=0.983X+0.298, $R^2=0.994$, Pearson's correlation coefficient showed 0.997, paired t-test (P=0.181), Difference (%) mean -5.53 made no statistically significant difference. Conclusion: Lipemic sample of low Anti-ds DNA Ab concentration (2.5-7 IU/mL) and the result is obtained pre-treatment (high-speed centrifugation: 14,000 rpm 5 mins) were made a significant difference statistically. Anti-ds DNA is one of the primary auto-antibodies present in patients with SLE, and remain an important diagnostic test for SLE. Therefore, we recommend preprocessing (high-speed centrifugation: 14,000 rpm 5 mins) in order to exclude the influence of lipemic specimen.
The aim of this paper is to examine the men's ideal lives and the aspects of variation in Sijo. In this paper the focus is two texts of Saseol-Sijo. One is the Saseol-Sijo without any known author, the other is the Saseol-Sijo written by Lee Jeong-bo. These works were enjoyed by many people to posterity, and they were played a variation. The first aspect of variation is the emphasis on men's magnanimous and amusable life. This aspect is thought to be a result of the interference of entertainment space. The second aspect of variation is to show the awareness of impossibility of riches and honors and belief in his alternative life. We can see the conflict between reality and desire. This case is thought to be enjoyed by the person who can sympathize with that situation. The third aspect of variation is to show the transcendence of desire for worldly success and the interest in a happy old age. This case is worthy of notice because it shows the interest in old age. This case expresses the desire for comfortable life or pleasure-seeking life, and it is thought to be more concerned with a concrete everyday life than an idea. Sometimes we can see the works that show reflection of his(her) life and mature attitude to life. More studies on these works should be done.
The use of the national pension funds to welfare has been criticized due to its low profitability, with concern about financial instability and the lack of funds. Despite the small amount of the funds employed to the welfare, therefore, it has been decreasing so far. It is resulted from the fact that the use of funds to the welfare sector failed to provide its valid reasons, and take the policy direction firmly. There are three main logical reasons for the welfare investment of national pension funds: Firstly, no state is capable to take the full responsibility for the entire social welfare, and therefore, the funds can be used for social welfare. Secondly, the funded system, contrasted with the case of pay-as-you-go system, has inevitably caused discriminations to the present elderly through excluding them institutionally from pension participation. At last, so as to its selective system, the minimum contribution period of 10 years brings about the equity problem between the people who can afford it and the people who hardly can. Therefore, investing a proportion of funds to the welfare is entirely reasonable in that it can alleviate the discriminations to the present elderly generation and the marginal participants, rather than to meet their social welfare needs. With regard to the policy decision, the profitability of the investment, and the choice of the welfare work, on the other hand, the policy direction should be given a sufficient consideration of a various policy factors such as the necessity of social consensus, independence of the welfare work in relations with other national welfare work, policy identity to judge whether the work is worth long-run or short-run, and the reliance of direct-operated work and indirect-operated work. As a result of all these efforts above mentioned, an investment to the welfare of the national pension funds could be vitalized, and gain public confidence.
