Objectives : This study is to investigate the clinical characteristics of psychiatric consultation for children and adolescents in a general hospital. Methods : Hospital records of 302 children and adolescents who were referred for psychiatric consultation in a general hospital over 4 years were reviewed and analyzed. Results : The mean referral rate for psychiatric consultation for school age children and adolescents was $2.15\%$. While more girls were referred in middle and high school age group, more boys were referred in pre-school age group. Fifty percent of the consultation was requested from department of internal medicine and pediatrics. Main reason for requesting psychiatric consultation was fur the assessment of the patients from psychiatric point of view $(31.1\%)$, followed by the management of depression $(11.6\%)$ and anxiety $(11.3\%)$. Most frequently rendered psychiatric services for the treatment was psychosocial education and supportive therapy $(21.2\%)$. Conclusion : There are differences in clinical nature of psychiatric consultation and referral patterns between adult patients and child and adolescent patients. Future research is needed to strengthen the services for child and adolescent psychiatric consultation.

Background: Dissection flaps in acute type A aortic dissection typically extend into the root, most frequently into the non-coronary sinus (NCS). The weakened root can be susceptible not only to surgical trauma, but also to future dilatation because of its thinner layers. Herein, we describe a new technique that we named the "neo-adventitia" technique to strengthen the weakened aortic root. Methods: From 2012 to 2016, 27 patients with acute type A aortic dissection underwent supracommissural graft replacement using our neo-adventitia technique. After we applied biologic glue between the dissected layers, we wrapped the entire NCS and the partial left and right coronary sinuses on the outside using a rectangular Dacron tube graft that served as neo-adventitia to reinforce the dissected weakened wall. Then, fixation with subannular stitches stabilized the annulus of the NCS. Results: There were 4 cases of operative mortality, but all survivors were discharged with aortic regurgitation (AR) classified as mild or less. Follow-up echocardiograms were performed in 10 patients. Of these, 9 showed mild or less AR, and 1 had moderate AR without root dilatation. There were no significant differences in the size of the aortic annulus (p=0.57) or root (p=0.10) between before discharge and the last follow-up echocardiograms, and no reoperations on the aortic roots were required during the follow-up period. Conclusion: This technique is easy and efficient for reinforcing and stabilizing weakened roots. Furthermore, this technique may be an alternative for restoring and maintaining the geometry of the aortic root. An externally reinforced NCS could be expected to resist future dilatation.

It is important to increase the strength of binders in order to enhance the strength of concrete. However, when the mineral admixture used for high strength concrete is incorporated individually, its dispersibility decreases due to the phenomenon of compaction, which reduces its fluidity and results in insufficient strength being created. To solve this problem, we can pre-mix each binder in advance to disperse a mineral admixture among binders, which will strengthen the fluidity and strength of concrete. Therefore, this study analyzed the properties of high strength concrete depending on the mix method used, to determine the effect of pre-mix cements ranging from W/B 15 to 35%. It was found that the fluidity of pre-mix increased to a level higher than that of individual mix due to its dispersion and ball bearing effect. The air content was slightly decreased from the result of individual mix due to the micro filler effect, which causes fine particles of silica-fume to fill the voids among cement particles, while the setting time of pre-mix was shorter than that of individual mix, because enhanced dispersion of pre-mix affects hydration heat time. The compressive strength of pre-mix increased due to the phenomenon of compaction of gap structure, and the variation of coefficient decreased by 1.69% on average in strength variation.

Early childhood caries which mainly affect maxillary anterior area, defined as 'the presence of 1 or more decayed, missing, or filled tooth surfaces in any primary tooth in a child 71 months of age or younger'. Extraction of teeth when early childhood caries affected in maxillary primary incisors often develops progressively, result in severe destruction of crowns, acute or chronic pulpitis, and periapical abscess formation. Maxillary primary incisors are need to preserve as possible, because the early loss of maxillary primary incisors may lead to various functional, esthetical, and psychological problems. It is necessary to the availability of an easy to perform technique capable of providing efficient, durable, functional, and esthetic restorative methods. Polyethylene fiber-reinforced post can be used in strengthen of composite resins that is esthetic and good physical and mechanical properties. $Ribbond^{(R)}$ is made from an polyethylene fiber, has numerous usages, its surface is treated to enhance adhesion to resins, ease of manipulation, relatively cost effective. We report this case, had restored of maxillary primary incisors with severe coronal destruction due to affecting severe early childhood caries, using polyethylene fiber-reinforced posts, composite resin cores, and celluloid crowns. We could obtain good result of treatment.
The Miaos who is the minority people mainly living in the southwestern part of China, expressed their indicator and solidarity through the costume in order to maintain their racial character while experiencing numerous adversities over thousands of years, where the costume has served as a source of cohesion as well as a primitive religious thought, and also showed their faith, desire, longing and aspiration. This study examined the Miao's traditional costume by classifying it into the following; hair style, headdress, upper and lower garments, and other costume. And the silver ornaments used for attire and their symbolic meaning were examined. The result of the study is summarized as follows. 1. The reason that types of the costume has been diversified is because there was promise of ancestors who intended to differently express the type of a kind as symbol of the racial branch that is the Miao's special type of society. Thus, the costume type could tell where a tribe live. Another reason is because only marriage between families with different surname but the same type of costume was accepted. 2. As women made and wore the costume themselves, it also served as a means of being proud of their skill or wealth, they tried to make it more beautiful and it was also used as a token of marriage or love between relatively enlightened men and women. 3. The design used on the costume was expressed as a symbolic meaning of indicator to strengthen the racial solidarity because it connoted worship to ancestors who had experienced lots of adversities. 4. The hair style was expressed in various styles by using Kache such as Chukye, Byunbal and Kokye. It is likely that ornaments used on the head of women in the form of cow's horn or silver crown were used as one of the methods to stress the valuableness of the cattle that were essential to agricultural life. In addition, various styles of turbans were used to indicate the respective regions. 5. Cock's feather ornaments or silver ornaments in the form of pheasant's feather on the edge of women's skirts, peasant's feathers that men wore on their head, or Baekjoui and men wore resulted from the Miaos' thought of adoration for birds, which implied a primitive religious meaning. 6. As the region where the Miaos live yields much silver, the silver ornaments were mostly used to be proud of wealth, which symbolized light and pureness.
While the ability to develop nanomaterials and incorporate them into products is advancing rapidly worldwide, understanding of the potential health safety effects of nanomaterials has proceeded at a much slower pace. Since 2008, Korea Food and Drug Administration (KFDA) started an investigation to prepare "Strategic Action Plan" to evaluate safety and nano risk management associated with foods, drugs, medical devices and cosmetics using nano-scale materials. Although there are some studies related to potential risk of nanomaterials, physical-chemical characterization of nanomaterials is not clear yet and these do not offer enough information due to their limitations. Their uncertainties make it impossible to determine whether nanomaterials are actually hazardous to human. According to the above mention, we have some problems to conduct the human exposure risk assessment currently. On the other hand, uncertainty about safety may lead to polarized public debate and to businesses unwillingness for further nanotechnology investigation. Therefore, the criteria and methods to assess possible adverse effects of nanomaterials have been vigorously taken into consideration by many international organizations: the World Health Organization, the Organization for Economic and Commercial Development and the European Commission. The object of this study was to develop risk assessment principles for safety management of future nanoproducts and also to identify areas of research to strengthen risk assessment for nanomaterials. The research roadmaps which were proposed in this study will be helpful to fill up the current gaps in knowledge relevant nano risk assessment.
The concept of pun was basically used to get rhetorical effect in verbal usage and it can be easily applicable to visual communication design. By substituting symbolic images for words of verbal expression, we can draw out some effective communication methods in forms of pun. For years, visual puns have been useful concept to convey a visual message from ancient hieroglyphics to modern arts and design. There are essentially three categories of visual puns. Literal pun upholds the primary meanings of the message literally by picking up a key symbol to create two or more meanings, meanwhile suggestive pun is created when one symbol is used as a key symbol or two or more symbols are combined to created one key symbol that can suggest and strengthen meanings. Comparative pun can be defined two or more symbols of nearly the same appearance are combined or juxtaposed two or more times to enhance overall statement. The concept of visual pun used for traditional area can also be effective ways of new media communication. Thus it is natural to see the concept of visual puns in website. How to handle the images in website is the most critical point for differentiation. But recently, web site designers just seem to focus on somewhat functional aspect. There are certain types of web design formats, and many designers are tend to follow these routines unconsciously. In this situation, the new aspect of visual puns for web design can be a possible design method to fortify the overall message. Through this concept, we can build up some clear identity compared to other web sites and can get alternatives to perform more effective communication ways as a problem-solving process.

This study tried to find out implementation factors of internal marketing for a cosmetic retailer, and to look into their effects on Salesperson's job satisfaction, organization commitment, customer orientation and sales performance. For this, this study inquired into the concepts and relationships of internal marketing, job satisfaction, organization commitment, customer orientation and sales performance through literature review; and tested the relationships between the variables by setting up a research model and hypotheses. The findings of this study may be summarized as follows: First, it was found that the better the education & training, the supervisor support and the compensation system among internal marketing factors of a cosmetic retailer were, the higher a door-to-door salesperson's job satisfaction was. Second, it was found that the better internal communication and the education & training among internal marketing factors of a cosmetic retailer were, the higher a door-to-door salesperson's organization commitment was. Third, the higher the job satisfaction of a door-to-door salesperson in a cosmetic retailer was, the higher the organization commitment was. Fourth, it was found that the higher the organization commitment of a door-to-door salesperson in a cosmetic retailer was, the higher the customer orientation was. Fifth, it was found that the higher the organization commitment and customer orientation of a door-to-door salesperson in a cosmetic retailer were, the higher the sales performance was. In conclusion, the internal marketing increases door-to-door Salesperson's job satisfaction, and enhances the sense of belonging to their cosmetic retailer. Further, they come to have a customer-oriented attitude in serving customers, which is directly connected to sales performance, and thus the retailer can create profits through internal marketing. Therefore, a cosmetic retailer will need to strengthen internal communication activities through diverse methods, expand and activate employees' professional education, and develop fair and just compensation system; and supervisors will need to give support to employees, trusting their judgment.

This cross-sectional descriptive study investigated the influence of romantic relationships' characteristics, self-esteem and sexual autonomy on limerence in dating relationships among female college students who had or were currently engaged in a dating relationship. The data was collected through self-reported structured questionnaires from 167 female Korean college students using convenient sampling methods from November 25, 2012 to December 20, 2012. The data was analyzed using t-tests, one-way analyses of variance, Scheffe's test, Pearson's correlation coefficients, and multiple linear regression analysis with the IBM SPSS 23.0 program. The results showed that a significant difference was found in limerence according to the frequency of experiencing romantic breakup (F=4.16, p=.003), and limerence in dating relationships was negatively correlated with self-esteem (r=-.31, p<.001) and sexual autonomy (r=-.21, p=.006). Self-esteem and the frequency of romantic breakups explained 20% of limerence in dating relationships among the participants (F=8.03, p<.001). Therefore, as a strategy to solve the problems related to limerence during the period of dating, cognitive and educational interventions are needed to strengthen the self-esteem and sexual autonomy of college students who have had a high number of separations. In addition, early screening of college students with risk factors for limerence and providing problem-solving based counseling will help improve their psychological health.
Purpose - The Northeast Asian Logistic Hub strategy was established to create a national competitive advantage in northeast Asia. Countries in this region are competing fiercely to become the central base distribution port as the volume of container shipping continues to increase due to the northeast Asian (especially Chinese) economic growth. The primary method by which shippers are improving their customer service and distribution is enhancing profits by minimizing call ports on the key route through strategic affiliations and the use of large vessels. Each nation is planning large-scale investments in the construction of sea ports that can accommodate large vessels. This paper proposes ways by which the logistical strategies of domestic corporations can keep pace with changes in government policy concerning the Northeast Asian Business Hub policy. It examines the logistics system in the Northeast Asian region, analyzes the government's Northeast Asian Business Hub policy, and suggests logistical strategies for domestic corporations through an analysis based on a questionnaire designed to grasp domestic firms' needs and goals. Research design, data and methodology - The purpose of this study is to determine how shipping companies establish partnerships with third-party logistics providers and draws out the implications of the results. The survey methods used were personal interviews and questionnaires distributed to a sample population through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, of which 165 were returned. Among these, ten were excluded due to insufficient content; ultimately, 155 were used for the sample. The statistical data collection process was analyzed through data coating and a statistical package program. Results - This study argues that greater flexibility in policies, administration, and systems will be needed to significantly improve established business practices. In this dissertation, we primarily identify that in order to become a center of northeast Asian logistics, Korea must adopt a new paradigm and abandon the existing systems that are based on the economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and equalitarianism. Flexible policies, administration, and systems will be necessary to improve business practices. Domestic corporations must establish a strategic logistics hub and related network while simultaneously pursuing value-added logistics businesses by increasing their manpower and building a logistics information system. This will strengthen their competitive edge and lead to system improvements. Conclusions - Domestic corporations must adopt a new paradigm and use more reasonable business laws, systems, and policies that are based on market-driven flexibility and transparency. Moreover, social norms and regulations should be established to help ensure political and social security. Korea must also develop a culture of tolerance for foreign companies. Finally, the paradigm defining the policy governing the development of the capital city and its satellite cities in this context must be changed.
