This paper reviews battering, sexual violence and divorce experienced among women. There three problems have negative influence on health status in women and are further developed to social problems such as family dissolution. The victims of the problems may manifest physical injury, emotional difficulties and social withdrawl, while their children may show problems caused by lack of parental caring and by resembling abusive behaviors of their parents. Hence, nurses need to pay attention to batting, sexual violence, and divorce and to develop relevant nursing interventions for them. Some strategies of dealing with those problems are presented in the following. First, we have to eliminate sexism prevailing in out society. Our society is assigning inequal and asymmetrical gender role. Mass media should inspire equality between genders and show a healthy model of family and community. Second, social system and laws should be changed through collective efforts. Those living conditions of women cannot be changed by the effort of women themselves only. We all need to work for establishing and changing the law, so that those women in suffering can obtain immediate and adequate protection. Third, social support system of consulting and referring women's problems should be established. Such support system as hot line, shelter and counseling clinics would help women in crisis. Fourth, job training and arrangement should be available to women who are divorced. Fifth, there should be self-help group for those women in suffering. Self-help group would help those women in sharing their problems and feelings and in establishing coping strategies. Nurses, as the largest group among health professionals, are sensitive and respond to health needs of clients and have an effect on managing women's health. However, we nurses have not been ready for dealing with problems of women, although most of us are women. we not need to change our perspective of women's health problems from a traditional medical perspective to feministic one. Accordingly, nurses need to develop realistic way of caring those women in suffering and to assist them in making decisions for their lives by themselves.

Occurrence of hydrogen embrittlement could be one of the main obstacles for using structural equipment under hydrogen environment. It is required to develop assessment methods of hydrogen embrittlement for the metals used in production, storage, transmission and application utilities of hydrogen. The most probable method of hydrogen mass transmission is using existing natural gas pipeline. Base or weld part of the pipeline can be damaged by mixed gas of hydrogen in the pipeline. In this study small punch (SP) testing was employed to evaluate the hydrogen embrittlement behavior for a line pipe steel (API X65) with electrochemically hydrogen charged specimens. Results showed that the SP test can be a good candidate test method for hydrogen damage evaluation method. Strength of steel is known to be decreased with the level of hydrogen charging. However, for API X65 steel base metal need in this study, the effect of hydrogen to strength was not significant. It can be negligible regardless of the hydrogen contents in the steel. With this test different strength levels with various hydrogen charging conditions were observed. It can also be anticipated that more sensitive evaluation of material behavior be obtainable by the SP test method.

The $HCO^+$ 1-0 transition line was observed toward the Sgr B2 region in our Galactic center. We found that there exist two large-scale velocity structures of $v_{lsr}\;{\sim}50\;and\;{\sim}100kms^{-1}$, which are thought to interact with each other. A new gas clump 'OF28 Cloud'('Odenwald & Fazio FIR 38' Cloud), showing different chemical and kinematical properties with the Sgr B2(M) cloud, was found in the $50kms^{-1}$ gas component. Toward the core of this component, we derive the $HCO^+$ total column density, $N(HCO^+)=(2-5){\times}10^{14}cm^{-2}$ and the mass $M=1{\times}10^6M_{\odot}$, by estimating its size, ${\sim}15pc$, from the half-power width of this component. We also found that there is a highly turbulent component in this region in the velocity range of about $100kms^{-1}$. The column density of this component is $N(HCO^+)=1{\times}10^{13}cm^{-2}$. The $HCO^+$ in this region may form effectively by the reaction between $C^+$ and OH, which are the elements whose abundances increase rapidly in shocked region.

A sensitive and simple analytical method to identify flutianil residues in agricultural commodities was developed and validated using gas chromatography-electron capture detection (GC-ECD) and mass spectrometry (GC-MS). The flutianil residues were extracted with acetonitrile, partitioned with dichloromethane, and then purified using a silica solid-phase extraction (SPE) cartridge. The method was validated using pepper, sweet pepper, mandarin, hulled rice, soybean, and potato spiked with 0.02 or 0.2 mg/kg flutianil. The average recovery of flutianil was 76.5-108.0% with a relative standard deviation of less than 10%. The limit of detection and limit of quantification were 0.004 and 0.02 mg/kg, respectively. The result of recoveries and relative standard deviation were in line with Codex Alimentarius Commission Guidelines (CAC/GL 40). These results show that the method developed in this study is appropriate for flutianil identification and can be used to maintain the safety of agricultural products containing flutianil residues.

Leukocytes are reportedly the first line of the innate immune defense and essential for the control of common bacterial infections. Therefore, in this work, the antibacterial activity of crocodile leukocyte extract against Propionibacterium acnes was evaluated, and we also characterized the related activity of skin infection. The leukocyte extract showed the minimum inhibitory concentration to be $100{\mu}g/ml$ to P. acnes. SEM imaging demonstrated that the leukocyte extract adversely affected P. acnes cell permeability in a concentration-dependent manner. Furthermore, the crocodile leukocyte extract could significantly reduce proinflammatory markers and decrease inflammatory signs in infected mouse ears. The crude leukocyte extract was further purified using FPLC and RP-HPLC. The resulting fraction F5 was indicated as the anti-acne peptide-containing fraction. The molecular mass of the peptide contained in F5 was calculated to be 4,790.5 Da. N-Terminal sequencing revealed the amino acid sequence as GPEPVPAIYQ, which displays similarities to immunoglobulin A and leucine-rich repeat neuronal protein. This is the first reported amino acid sequence of a crocodile leukocyte extract that possesses anti-acne activity. To attempt to use it in a prototype cosmetic, an anti-acne gel containing crude crocodile leukocyte extract was formulated, resulting in seven gel formulations (G1, G2, G3, G4, G5, G6, and G7). The formulations G5, G6, and G7 exhibited 2-fold higher anti-acne activity than G1-G4. Investigation of accelerating stability studies of anti-acne gel formulations G5, G6, and G7 demonstrated that a low storage temperature ($4^{\circ}C$) is suitable for maintaining the physical properties and biological activity of the anti-acne gel products.

Objectives: The present study was undertaken to evaluate the immunomodulatory (IM) activity of IM-133N, a herbal combination in various immunotherapeutic experimental models. Methods: The IM activity of IM-133N was evaluated against three experimental models namely, effect of IM-133N against Escherichia coli (E. coli)-induced abdominal sepsis in mice, and carbon clearance test was performed in Wistar albino rats to evaluated the phagocytic potential of IM-133N, in addition IM-133N was evaluated for its immunoglobulin enhancing potential in rats, where the immunoglobulin levels were measured by zinc sulphate turbity (ZST) test. Further, IM-133N was subjected for detailed liquid chromatography-mass spectrometry (LC-MS)/MS analysis to identify the probable active constituents present in it. Results: The findings of the present study has demonstrated very promising IM property of IM-133N in all the experimental models. Briefly, pretreatment with IM-133N at 125, 250, 500 and 1,000 mg/kg, p.o. doses had protected the mice against E. coli-induced abdominal sepsis and mortality, further the effect of IM-133N was found to be significant and dose-dependent. In support of this, in another study administration of IM-133N showed a significant and dose-dependent increase in serum immunoglobulin levels, estimated by ZST test. In line with the above findings, in the carbon clearance test the low doses (125 and 250 mg/kg, p.o.) of IM-133N increased the rate of carbon clearance, whereas the higher doses (500 and 1,000 mg/kg, p.o.) did not sustain the response, and saturation effect was considered as one of the possible reason for futility of higher doses for IM-133N. In addition, A detailed LC-MS/MS analysis of IM-133N showed 17 bioactive phytochemical constituents: namely, apigenin, chaulmoogric acid, mesquitol, quercetin, symphoxanthone, salireposide, ${\beta}$-sitosterol, nonaeicosanol, ${\beta}$-amyrin, betulic acid, oleanolic acid, symplososide, symponoside, symploveroside, symplocomoside, symconoside A and locoracemoside B. Conclusion: These findings suggest that IM-133N possesses significant IM activity and, hence, could be useful for eradicating opportunistic disease-triggering pathogens via immunotherapeutic mechanisms. The findings also suggest IM-133N may also useful in other immunity disorders.

This study is the first ever attempted series paper of one particular TV drama writer, Su-Hyeon Kim, with diversified and systematic scale. Along with the just before study, proving Su-Hyeon Kim's line's conceptual properties as the Bahktin's dialogism, its core of polyphony, this study is to analyze the concrete method of creation through Bahktin's Canivalistic creation component of 'Grotesque Realism' and 'Unofficial Square Language'. With her work of (SBS, 1992), this study verifies its characteristic creation of lines to be the 'Grotesque Realism' components of overturn, destruction, and creation along with 'Unofficial Square Language' components of the masses, material, physical language, and discourse of self-liberation. In this way, this study is on one hand, to overcome the application problem of Bahktin's theory as a separated one, but also to enhance the quality of the study of the writer and the lines. As a result, she has acquired her own distinction of ambivalence by the way of demotion, overturn with masses' material, physical, unofficial square language along with a stronger execution of acquiring self denial, positivity. liberation, and life. Therefore the writer is highly rated for her fierce cognition of language and her artistic spirit. Also, this paper proposes the following study to appraise the impact of the writer's differentiation and artistic spirit on the creation of Korean TV drama, contents industry, and mass media.
