National Competency Standards (NCS) need to be introduced to train newly hired staff and to gradually improve employees' work performance in the information security industry. In particular, the introduction of a new NCS curriculum for new hires is important in order to retain and efficiently manage professionals in the information security field. However, the legacy NCS is not clearly designed for the information security field. So a formal curriculum has been suggested for institutions training the information security workforce. Therefore, this study establishes a competency unit based on the types of personnel, their duties, and required knowledge. To select the competency unit, this study reviewed prior research to understand the required skills and work knowledge, and reviewed recruitment-based NCS that public agencies and public and private companies have carried out, including them in the study. The selected competency unit was classified into a required competency unit and an elective competency unit based on the importance of the duties and the demands of training. Through a verification process for the new, licensed career path model in the NCS information and communications field, this study suggests updated NCS competency units and required courses to provide an appropriate NCS curriculum for newly hired employees in the information security industry.

An area of current research is investigating the app1ication of human mesenchymal stem cells or hMSCs as a cell-based regenerative therapy. In order to achieve effective bone regeneration, appropriate matrices functioning as cell-carriers must be identified and optimized in terms of function, efficacy and biocompatibility. Two methods of approaching optimization of matrices are to facilitate adhesion of the donor hMSCs and furthermore to facilitate recruitment of host progenitor cells to osteoblastic differentiation. Pleiotrophin is an extracellular matrix protein that was first identified in developing rat brains and believed to be associated with developing neuronal pathways. A recent publication by Imai and colleagues demonstrated that transgenic mice with upregulated pleiotrophin expression developed a greater volume of cortical as well as cancellous bone. The proposed mechanism of action of pleiotrophin is demonstrated here. Through either environmental stresses and/or intracellular regulation, there is an increase in pleiotrophin production. The pleiotrophin is released extracellularly into areas requiring bone deposition. A receptor-mediated process recruits host osteoprogenitor cells into these areas. Therefore, the aim of our study was to investigate the osteoconductive properties of pleiotrophin. We wanted to determine if pleiotrophin coating facilitates cellular adhesion and furthermore if this has any effect on hMSCs derived bone formation in an animal model. The results showed a dose dependent response of cellular adhesion in fibronectin samples, and cellular adhesion was facilitated with increasing pleiotrophin concentrations. Histologic findings taken after 5 weeks implantation in SCID mouse showed no presence of bone formation with only a dense fibrous connective tissue. Possible explanations for the results of the osteogenesis assay include inappropriate cell loading.

We have reported that a 24 kDa protein (22U homologous; As22U) of Anisakis simplex larvae could elicit several Th2-related chemokine gene expressions in the intestinal epithelial cell line which means that As22U may play a role as an allergen. In order to determine the contribution of As22U to allergic reactions, we treated mice with 6 times intra-nasal application of recombinant As22U (rAs22U). In the group challenged with rAs22U and ovalbumin (OVA), the number of eosinophils in the bronchial alveolar lavage fluid (BALF) was significantly increased, as compared to the group receiving only OVA. In addition, mice treated with rAs22U and OVA showed significantly increased airway hyperresponsiveness. Thus, severe inflammation around the airway and immune cell recruitment was observed in mice treated with rAs22U plus OVA. The levels of IL-4, IL-5, and IL-13 cytokines in the BALF increased significantly after treatment with rAs22U and OVA. Similarly, the levels of anti-OVA specific lgE and lgG1 increased in mice treated with rAs22U and OVA, compared to those treated only with OVA. The Gro-${\alpha}$ (CXCL1) gene expression in mouse lung epithelial cells increased instantly after treatment with rAs22U, and allergy-specific chemokines eotaxin (CCL11) and thymus-and-activation-regulated-chemokine (CCL17) gene expressions significantly increased at 6 hr after treatment. In conclusion, rAs22U may induce airway allergic inflammation, as the result of enhanced Th2 and Th17 responses.

Being in the globally competitive environment, public port enterprises which accentuate on the employment of excellent talents to procure competitive advantage are introducing the NCS(National Competency Standards)-based employment system that focuses on job skills. This study mainly aims to analyze the actual status of NCS utilization among public port enterprises and its usefulness as well as performance. The appropriateness, efficiency, satisfaction, comprehensiveness and performance of the current NCS - based employment system were analyzed by using collected data from the recruiting officers and new employees as subjects. And eventually an improvement plan was suggested. The result of analysis shows that the appropriateness and satisfaction level of NCS - based employment system are generally high; while its effectiveness, applicants' recognition and acceptance level as well as performance are slightly higher. Moreover, the job capability and performance on the job of new employee selected by the NCS employment system were analyzed to be higher when the appropriateness and satisfaction level of that system is high. In order to establish NCS - based employment system, early formulation and implementation of job performance assessment system to evaluate the actual abilities and performance of job is necessary. This study suggested the NCS - based employment system is effective for public port enterprises to procure excellent talents, as well as being useful for job preparation of job seekers according to the job competencies requirement of the enterprises. Therefore, this study contributes to the proliferation of NCS - based recruitment system.

Background : Although the pathophysiology of asthma has been reported, its mechanism has not been fully elucidated. The mast cell is an effector cells in allergic inflammation and secretes a number of chemokines. Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. Chemokines also contribute to the pathogenesis of several disorders such as asthma, chronic bronchitis, atopic dermatitis, allergic rhinitis, and rheumatoid arthritis. Objective : In this study, the aim was to identify the effect of Baekryunchihyo-tang(白蓮治哮湯) on expression of chemokines. This was examined by RT-PCR using the human mast cell line (HMC-l) Materials and Methods : HMC-l cells were used, which is known to secrete and express chemokines. In order to investigate the protective effect of Baekryunchihyo-tang(白蓮治哮湯), HMC-l cells were incubated with pretreatment of Baekryunchihyo-tang(白蓮治哮湯) for 24 hrs. RT-PCR analyses of chemokine genes of cells pretreated with Baekryunchihyo-tang(白蓮治哮湯) showed that expressions of IL-8, $MIP-l{\beta}$, and RANTES genes in these cells were lower and $MIP-l{\alpha}$ showed a similar pattern compared to the calcium ionophore-treated group. In addition, cell cytotoxicity concentration measurements were performed by MTT assay method. Results : After stimulation with 1 uM calcium ionophore A23178 for 2 hrs, IL-8, major one of CXC chemokines, was highly expressed, and expression of $MIP-l{\beta}$ and RANTES (CC chemokines) increased, while expression of $MIP-l{\alpha}$ did not change. The cell cytotoxicity of Baekryunchihyo-tang(白蓮治哮湯) with treatments at various concentrations and times was not observed, respectively. Conclusion : This study suggests that Baekryunchihyo-tang(白蓮治哮湯) has dose-dependent effects on mRNA expression of IL-8(CXC chemokines), $MIP-l{\beta}$ and RANTES(CC chemokines) in human mast cellline(HMC-l). So these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanism of inhibition by herbal medicine in the asthma model. This study provides basic data on the possibility of the clinical treatment of Baekryunchihyo-tang(白蓮治哮湯) for allergic disorders.

The major purpose of this study is to scrutinize and analyze various factors in numerous aspects of two different library systems for the visually handicapped, namely braille library and a special section for the visually handicapped in the public library system. The analyses may provide theoretical and conceptual framework on which strategies to enhance services for the visually handicapped is to be developed. More specifically, this study seeks (1) to examine a linkage between the degree of maintenance of staffs, collections, and equipment and the level of satisfactions of librarians and (2) to come up with more effective mechanisms of welfare services for the visually handicapped in each library system. This research is qualitative-descriptive and uses interview method. Fourteen libraries throughout the nation (4 public libraries with a reading room for the visually handicapped and 8 braille libraries) which had been in operation more than one year were selected as subjects for the research. Findings and results of the analyses are summarized as follows : 1. There seems to be general consensus that each of public and braille library has significant but, to a certain extent, different roles to play in order to enhance library services for the visually handicapped. Recruitment of qualified librarians, increase of the volume of collection, and enlargement of reading room space are noted as immediate concerns for the former. For the latter, it was suggested that increase of the number of staff for publishing, securing more equipments for pulication in braille, and wider scope as well as more variety of publications are the pressing problems at hand. 2. Both public and braille library employ one librarian for the visually handicapped who is required to have educational background in library science and special education. In addition, one must have competence in reading braille types. 3. Majority of reading rooms in those libraries is so small in physical aspect that size and number of seats are 66m2 and 15 seats respectively because circulation services are mainly in use due to the problem of inaccessibility which is commonly suffered by the visually handicapped. 4. Library services for the visually handicapped are heavily concentrated upon the large urban area. In fact, most of braille libraries are located in Seoul whereas a reading room for the visually handicapped in the public library system are exclusively placed in the large cities such as Inchon, Taejon, and Taegu. 5. All of the public library is neither equipped with necessary facilities to publish in braille nor secured supporting instruments which may facilitate library use for the visually handicapped. On the contrary, most of braille libraries are equipped with arrangements to publish in braille despite supporting devices are gererally lacking. 6. Consequently, provision of services In the public library is largely confined to reading and circulation of materials purchased from braille libraries while major task of braille libraries centers around publication and distributions of the reading materials in braille.

This paper analyzes the effectiveness of social networks in finding jobs and estimates the value of job search network using the Korean Laber and Income Panel Study (KLIPS) dataset and utilizing the Difference-in-Difference Propensity Score Matching (PSM) methodology (Heckman et al., 1997). While the wide use of social networks in the Korean labor market is often perceived as 'nepotism,' this study confirms that social networks, by serving as an effective information transmitter between job search and recruitment, make a significant contribution to improving the adequacy of job matching in the domestic labor market. In order to verify the effectiveness of using social networks for getting jobs, this study looks into the cases of labor turnover using social networks and also not using it. In the aspect of individual satisfaction improvement relating to workplace and job duties, both cases of turnover turn out to experience an increased satisfaction by 2~3 points (on a 100-score scale). Meanwhile, as for the educational and technical adequacy improvement, no positive effects are found in the case of turnover without social networks, whereas the educational and technical adequacy improvement turns out to increase by 2.13 and 2.52 points, respectively, in the case of turnover using social networks. The effect of income increase through turnover using social networks registered 40,074 Korean won per month (as of 2010), which can be considered as the result from the improved educational and technical adequacy. Of all things being considered, the value of job search network per wage worker in the Korean society is estimated to be 18.72 million won in terms of life-cycle wage improvement, and 758.2 scores in terms of the improvement of working life satisfaction. Provided that the cash value of satisfaction score 1 is equivalent to 'n' times 10,000 won, the aggregate value of job search network is estimated to be 18.72+7.582n million won, which means the total amount of costs that a wage worker in the Korean society willingly pays to maintain and manage job networks for lifetime.

Objectives : In this study, we conducted a focus group interview among expatriates living in Korea, to investigate their experiences and perceptions of acupuncture and Korean Medicine in order to improve the usage of Korean Medicine in the medical tourism market. Methods : The inclusion criteria for the focus group interview was: (1) participants between the age of 20 to 75 years old; (2) those who had lived in Korea for more than 90 days, and (3) those who were able to express their thoughts freely in English. The participants were informed that the interviews will be recorded and transcribed. We ended recruitment once saturation of materials was met. Semi-structured interviews were conducted, and the data was analyzed after each interview. Results : The interviews were held between June to December 2016. Twenty-four participants were recruited but four dropped out and a total of twenty participants successfully finished the interviews. Six focus group interviews were conducted. Analysis revealed that Korean Medicine was relatively less known compared to Traditional Chinese Medicine or Complementary and Alternative Medicine. Participants automatically associated acupuncture with the management of pain or stress and replied that these were the areas that they thought acupuncture would be most effective. Positive experiences with acupuncture and with the acupuncture practitioners were factors that promoted the use of acupuncture whereas lack of awareness, accessibility and accreditation were factors that hindered its use. Other factors that hindered the use of acupuncture was needle phobia and the perception that acupuncture lacks scientific evidence. Conclusions : Awareness on Korean Medicine and acupuncture is low. Participants lack awareness on what diseases acupuncture can treat, the scientific evidence behind the mechanism of action, and the rigorous education system that Korean Medicine doctors must go through to get their license. Rigorous marketing should be encouraged, which includes greater exposure in the media, more honest reviews from patients, and promotion of the scientific evidence base.
