The purpose of this study was to investigate music therapists' awareness of the music therapy national certification (MTNC). Online questionnaires were distributed to music therapists who voluntarily agreed to participate in this research and 143 completed surveys were collected for analysis. The questionnaire consisted of 37 questions (background information, awareness of the necessity for MTNC, expected effects of national certification, and qualification management). According to the collected data, music therapists reported that they were highly aware of the necessity for MTNC. The participants believed that excessive issueing of private licenses might deteriorate the quality of music therapy services and job opportunities. As alternatives to address private license-related issues, participants agreed with the establishment of national certification system. Given that participants did not have enough knowledge of MTNC and the MTNC may have both pros and cons, the results should be generalized with caution. Still, this study could provide basic information for further discussion on the establishment of MTNC.

Cancer is genetically, metabolically and infectiously induced life threatening disorder showing aggressive growing pattern with invasive tendency. In order to prevent this global menace from jeopardizing human life, enormous studies on carcinogenesis and treatment for chemotherapy resistance have been intensively researched. Hinokitiol (${\beta}$-thujaplicin) extracted from heart wood of cupressaceous is a well-known bioactive compound demonstrating anti-inflammation, anti-bacteria and anti-cancer effects on several cancer types via apoptosis and autophagy. This study proposed that hinokitiol activates transcription factor EB (TFEB) nuclear translocation for autophagy and lysosomal biogenesis regardless of nutrient condition in cancer cells. Mitophagy and ${\beta}$-catenin translocation into the nucleus under treatment of hinokitiol on non-small cell lung cancer (NSCLC) cells and HeLa cells were investigated. Hinokitiol exerted cytotoxicity on HeLa and HCC827 cells; moreover, artificially induced autophagy by overexpression of TFEB granted imperfect sustainability onto HeLa cells. Taken together, hinokitiol is the prominent autophagy inducer and activator of TFEB nuclear translocation. Alternative cancer therapy via autophagy is pros and cons since the autophagy in cancer cells is related to prevention and survival mechanism depending on nutrition. To avoid paradox of autophagy in cancer therapy, fine-tuned regulation and application of hinokitiol in due course for successful suppressing cancer cells are recommended.

The study was performed to identify the process of change, decisional balance, self-efficacy and social support corresponding to the stage of exercise behavior change and the applicability of social support of women in nursing college based on a Transtheoretical Model. The subjects consisted of 223 women in nursing college by convenience sampling and the data were analyzed by IBM SPSS 21.0 program. The subjects were distributed in each stage of change of behaviors: 17.9% in the precontemplation stage, 54.3% in the contemplation stage, 16.6% in the preparation stage, 4.5% in the action stage and 6.7% in the maintenance stage. Analysis of variance showed that consciousness raising, dramatic relief, self reevaluation, social liberation, counter conditioning, helping relationship, reinforcement management, self liberation, stimulus control, pros, cons and self-efficacy were significantly associated with the stages of exercise behaviors. But there was no significant difference in social support. The transtheoretical model would be applicable to explain the exercise behavior of women in nursing college. This study will be useful information for developing effective exercise programs considering nursing female students' stages of change in exercise behavior.

The purpose of this study is to investigate the opinions of non-health science college students of Korean dental hygienists in the category of medical personnel. A self-reported questionnaire was conducted on 265 non-health science major students without information about a health and medical service personnel. The collected data were analyzed using frequency, percentage, descriptive statistics, chi squared and multinomial logistic regression analysis. About 40% of the respondents answered that dental hygienists should be medical personnel, while 17.7% think that they should not distinguish health and medical service personnel between medical personnel and medical service technologist. As the respondents' oral health management ability improved, they approves the Korean dental hygienists in the category of medical personnel(p=.022). As the longer the period of dental regular visits, they answered that dental hygienists should be medical service technologist. Presence or absence of dental regular visits, scaling experience, oral health education did not no significant difference on the opinions of Korean dental hygienists in the category of medical personnel of the pros and cons. This study can be used as a basic data for establishing the policy of medical personnel for dental hygienists.

It has become possible for small scale laboratories to interpret large scale genomic DNA, thanks to the reduction of the sequencing cost by the development of next generation sequencing (NGS). De novo assembly is a method which creates a putative original sequence by reconstructing reads without using a reference sequence. There have been various study results on de novo assembly, however, it is still difficult to get the desired results even by using the same assembly procedures and the analysis tools which were suggested in the studies reported. This is mainly because there are no specific guidelines for the assembly procedures or know-hows for the use of such analysis tools. In this study, to resolve these problems, we introduce steps to finding whole genome of an unknown DNA via NGS technology and de novo assembly, while providing the pros and cons of the various analysis tools used in each step. We used 350Mbp of Toxocara canis DNA as an application case for the detailed explanations of each stated step. We also extend our works for prediction of protein-coding genes and their functions from the draft genome sequence by comparing its homology with reference sequences of other nematodes.

This study suggests a method for making a system of basic materials for the restoration of the 3X3 Kan central hall remains of a Buddhist temple from the Joseon Dynasty. Because there are both an extant hall and remains from the Joseon Dynasty, the basic material can be constructed through comparison with the floor plan. Multi-step comparisons were found to be the most suitable example for restoration. For this study, five parts of the 3x3 Kan remains were compared with 70 extant halls for a case study. For the first comparison, the limit of collection makes four examples in the whole examples. There are many relationships with the area and the length ratio of the front to the side as the comparison articles, so there are examples that satisfied both comparison articles. However, there is little relationship between the length ratio of the front Eokan to the front Hyeopkan and the length ratio of side Eokan to the side Hyeopkan. The construction method of the basic material shows the possibility of expansion with various directions that have pros and cons.

In this study, we surveyed information systems(IS) personnel in organizations which have adopted customer relationship management(CRM) systems (Group one IS personnel), those in organizations which plan to adopt CRM systems(Group two IS personnel), and IS consultants specialized in the CRM. We found that there are significant perception gaps among the three groups of IS practitioners in regard to the three aspects of CRM systems: the effects of CRM systems, critical success factors of CRM systems introduction, and the pros and cons of outsourcing a CRM system by the application service providers(ASP). The results reveal that Group one IS personnel evaluate the effectiveness of their CRM systems as moderate, while IS consultants evaluate the effectiveness of CRM systems very high and that Group two IS personnel expect the effectiveness of CRM systems to be as high as the evaluation of IS consultants. IS personnel evaluated the advantages of outsourcing CRM systems by ASP to be moderate while IS consultants evaluated it to be high. The results also show that the adoption of CRM systems is initiated by strong leadership of the top management but is not supported adequately by management thereafter.

In the past several years, many systems which adopted ring topology with high-speed unidirectional point-to-point links have emerged to overcome the limit of bus for interconnection network of clustered multiprocessor system. However, rapid increase of processor speed and performance improvement of local bus and memory system limit scalability of system with point-to-point link of standard bandwidth. Therefore, necessity to extend bandwidth is emphasized. In this paper, we adopt PANDA system as base model, which is clustering-based multiprocessor system. By simulating a model adopting commercial processor and local bus specification, we show that point-to-point link is bottleneck of system performance, and bandwidth expansion by more than 200% is needed. To expand bandwidth of interconnection network, it needs excessive design cost and time to develop new point-to-point link with doubled bandwidth. As an alternative to double bandwidth, we propose several ways to implement dual ring -simple dual ring, transaction-separated dual ring, direction-separated dual ring- by using off-the-shelf point-to-point links with IEEE standard bandwidth. We analyze pros. and cons. of each model compared with doubled-bandwidth single ring by simulation.

The health status of workers in a foundry was analyzed in a study which consisted of evaluations of respiratory health together with environmental measurements. The results from environmental measurements showed values exceeding permissible exposure limits. A t-test was done with log transformed and untransformed data to examine the statistical significance for the noncompliance with exposure standards. For the analysis of categorical health outcomes, $\chi$-square test with 2 $\times$ 2 tables and logistic regression analysis were employed. For continuous variables, multiple linear regression was done against assessed risk factors. Pros and cons of different parameters in the compliance (or noncompliance) testing were presented. Respiratory function did not show any relation with occupational exposures, which may be due to the healthy worker effects. Strategies for controlling time dependent covariates were discussed in relation to the healthy worker effect. The scope of statistical analysis in occupational health studies is still limited in Korea without a suitable external comparison group such as credible vital statistics for the whole nation. Internal comparisons between different exposure status often result in unstable estimates of effect, and proportional morbidity study is discussed as an alternative potential research tool.

As the information technology industry develops, various kinds of data are being created, and it is now essential to process them and use them in the industry. Analyzing and utilizing various digital data collected online and offline is a necessary process to provide an appropriate experience for customers in the industry. In order to create new businesses, products, and services, it is essential to use customer data collected in various ways to deeply understand potential customers' needs and analyze behavior patterns to capture hidden signals of desire. However, it is true that research using data analysis and UX methodology, which should be conducted in parallel for effective service development, is being conducted separately and that there is a lack of examples of use in the industry. In thiswork, we construct a single process by applying data analysis methods and UX methodologies. This study is important in that it is highly likely to be used because it applies methodologies that are actively used in practice. We conducted a survey on the topic to identify and cluster the associations between factors to establish customer classification and target customers. The research methods are as follows. First, we first conduct a factor, regression analysis to determine the association between factors in the happiness data survey. Groups are grouped according to the survey results and identify the relationship between 34 questions of psychological stability, family life, relational satisfaction, health, economic satisfaction, work satisfaction, daily life satisfaction, and residential environment satisfaction. Second, we classify clusters based on factors affecting happiness and extract the optimal number of clusters. Based on the results, we cross-analyzed the characteristics of each cluster. Third, forservice definition, analysis was conducted by correlating with keywords related to happiness. We leverage keyword analysis of the thumb trend to derive ideas based on the interest and associations of the keyword. We also collected approximately 11,000 news articles based on the top three keywords that are highly related to happiness, then derived issues between keywords through text mining analysis in SAS, and utilized them in defining services after ideas were conceived. Fourth, based on the characteristics identified through data analysis, we selected segmentation and targetingappropriate for service discovery. To this end, the characteristics of the factors were grouped and selected into four groups, and the profile was drawn up and the main target customers were selected. Fifth, based on the characteristics of the main target customers, interviewers were selected and the In-depthinterviews were conducted to discover the causes of happiness, causes of unhappiness, and needs for services. Sixth, we derive customer behavior patterns based on segment results and detailed interviews, and specify the objectives associated with the characteristics. Seventh, a typical persona using qualitative surveys and a persona using data were produced to analyze each characteristic and pros and cons by comparing the two personas. Existing market segmentation classifies customers based on purchasing factors, and UX methodology measures users' behavior variables to establish criteria and redefine users' classification. Utilizing these segment classification methods, applying the process of producinguser classification and persona in UX methodology will be able to utilize them as more accurate customer classification schemes. The significance of this study is summarized in two ways: First, the idea of using data to create a variety of services was linked to the UX methodology used to plan IT services by applying it in the hot topic era. Second, we further enhance user classification by applying segment analysis methods that are not currently used well in UX methodologies. To provide a consistent experience in creating a single service, from large to small, it is necessary to define customers with common goals. To this end, it is necessary to derive persona and persuade various stakeholders. Under these circumstances, designing a consistent experience from beginning to end, through fast and concrete user descriptions, would be a very effective way to produce a successful service.
