There is very high preference for the firms to locate in the Capital region, the City of Seoul and its surrounding areas, which inevitably meets diverse types of regulations to prevent over-concentration in Korea. In order to suggest an urgent need to reform these regulations, the demand for knowledge-based industries is estimated. A legit model is employed to estimate the demand of relocation of the current firms based on a survey conducted in 2001. A logistic curve is used to forecast the demand of new start-ups in Korea. The lands for industrial use only are estimated as many as 2.1 million~3.9 million pyung(1 pyung=3.3$m^2$) in nation-wide. Considering affiliate facilities and infrastructures, 3.1 million~5.9 million of industrial area should be developed in Korea for next five years. Since the rents are very high and the available land is short in the southern parts of Seoul, where most knowledge-based firms locate right now. Many firms have considered relocating on any other places where there exist a plenty of lands available and cheaper rents and cheaper wage rates, but still not far away from Seoul so that they could obtain new advanced information, skilled labors, venture capitals, and high quality of producer services. The Capital region, especially Gyeonggi and Incheon, is the only place to meet those conditions in Korea.

Purpose of this study is present the normal range of cardiac size and cardiothoracic ratio according to patient position(chest PA and AP) and age of Korean adult male on digital chest X - ray, And to propose a mutually compatible conversion rate. 1,024 males were eligible for this study, among 1,300 normal chest patients who underwent chest PA and low-dose CT examinations on the same day at the 'S' Hospital Health Examination Center in Seoul From January to December 2014. CS and CTR were measured by Danzer (1919). The mean difference between CS and CTR was statistically significant (p<0.01) in Chest PA (CS 135.48 mm, CTR 43.99%) and Chest AP image (CS 155.96 mm, CTR 51.75%). There was no statistically significant difference between left and right heart in chest PA and AP images (p>0.05). CS showed statistically significant difference between Chest PA (p>0. 05) and Chest AP (p<0.05). The thorax size and CTR were statistically significant (p<0.01) in both age and chest PA and AP. Result of this study, On Chest AP image CS was magnified 15%, CTR was magnified 17% compare with Chest PA image. CS and CTR were about 10% difference by changing posture at all ages.

The purpose of this study was to collect basic data for the development of effective oral health education program in elementary school. The subjects in this study Were 604 fourth-year, fifth-year and sixth-year students of an elementary school in Seoul, Oral health awareness and behaviors were surveyed and analyzed. The findings of this study were as follows: 1. The most common time for toothbrushing was after dinner(62.0%) and before bedtime(62.3%). By school year, the largest number who brushed their teeth after dinner were fourth and fifth graders while the greatest number who did so after breakfast were sixth graders. Seventy-four percent of respondents brushed the teeth twice or more a day. By school year, the fifth-year students brushed their teeth the least while girls outperformed the boys in daily toothbrushing frequency(p<0.05). Regarding the intake of cariogenic food, 62.1% took that kind of food once or more a day. By school year, the fifth graders took the most (p<0.05), and girls took more cariogenic food than the boys(p<0.05). 2. Ninety percent of the respondents had visited a dental clinic. By grade, the sixth-year students had visited a dental clinic more frequently and girls more frequently than boys. Eighty percent of the respondents visited a dental clinic to receive treatment but just 12.3% visited a dental clinic to prevent oral diseases. Concerning the fear of dental treatment, only 14.4% expressed fear. School year made no difference, yet the percentage of girls who experienced fear was higher than that of boys(p<0.05). Regarding preventive treatment, 39.7% experienced pit and fissure sealing and 24.2% experienced the application of fluorides. All the students hadn't much experience in preventive treatment regardless of school year -- gender didn't make a difference. 3. Fourty-six percent of respondents had a preference for the fluoride mouth rinsing program; 38.4% wanted that program to continue. As to the reason for preference, 38.2% preferred it because of the prevention of dental caries, 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do(some of the respondents gave two different answers). 4. Despite an increase in the frequency of toothbrushing at the right time, they still took cariogenic food frequently. Their visit to a dental clinics also aimed at treatment more than at prevention, and they had very narrow experience of preventive treatment Furthermore, the fluoride mouth rinsing program failed to draw their interest Therefore, it is recommended that a successful oral health education program should be developed.

Advance directive refers to a description of the treatment method a patient wants to be provided with in case where the person is unconscious or lacks an ability to decision making in a future period or a declaration of intention that delegates and appoints another person who makes a decision regarding a treatment method on behalf of the person. Advance directive is usually a document form, but oral statement is acceptable as well. Advance directive may have a variety of forms though, it basically consists of two basic forms. That is, one is a living will, and the other is a surrogate decision making. Though the importance of advance directive has been emphasized, and the necessity of adopting the system has been strongly argued for so far, the debates on criteria, method, and procedure alike have not yet reached an agreement. It is because even the concept of advance directive is more or less ambiguous, and each specific method has its own theoretical limitations and practical constraints. Thus the inquiries on advance directive raised in the study are summarized as the meaning, practicability, and philosophical foundation of the advance directive. Firstly, the theoretical limitations of Advance directive may be categorized into conceptual and moral limitations. In case of conceptual limitations, authors of advance directives may not be well aware, in advance, of the particular situation in which he or her will experience in the future, and patients may experience the change in his or her values and lack the understanding and information about the future situation due to the changes in treatment methods. In case of moral limitations, a patient has a limited moral autonomy right and self identity that have an impact on his or her preference. Secondly, in case of practical constraints for advance directive, there exist cultural features, low ratio of documentation, as patients themselves admit, and low predictability and stability of patient's own preference regarding life-sustaining care. And the problem of validity and accuracy in proxy's decision making is also raised. Those who administer a living will, especially, may have a difficulty in understanding the directive by a patient, so that the accuracy of execution cannot be secured. In the sense, it is needed to implement a legal device in order to solve such problems. In summary, it is urgently required to understand the limitations and explore desired alternatives to overcome the relevant problems in advance, which must contribute to successfully adopting and effectively operating the advance directive system in Korea.

Thromboembolic disease associated with assisted reproductive techniques is considered to be extremely rare but most serious complication. The reasons for this are thought to hypercoagulable state characteristic of OHSS due to high serum levels of estrogen, hemoconcentration and reduced circulating blood volume, but is still unclear. The risk is increased those with rare hypercoagulable conditions such as antiphospholipid antibody syndrome, protein C deficiency, protein S deficiency, antithrombin III deficiency, and those with a personal or family history of thromboembolic disease. The majority of thrombosis reported were venous site but arterial thrombosis mostly intracerebral was reported 5 cases in Korea so far. We present a case of basilar a. thrombosis at 11 days after hCG injection. The patient developed the right hemiparesis, and recovered after intraarterial thrombolysis and transluminal angioplasty. Protein S activity was decreased and vWF antigen was increased. Decreased protein S activity was also found in previous reported 4 cases, so we suggest screening test for protein S in OHSS patients.

Students have chosen the various behaviors to prepare for the future during the university life. In general to be employed by someone and to create one's own business is likely to be regarded as difference ways. The objectives of this study is to find that whether student's planned behaviors such as albeit, internship, getting some certification are to be related with entrepreneurial intention, and entrepreneurial intention has positive relation with entrepreneurial decision makings based on theory of Planned behaviors through empirical study. In order for that, this study sets four research hypothesis. In the empirical findings, 3 research hypothesis except H2 (subjective norms have positive relations with entrepreneurial intention) are accepted in statistically. Considering research findings, students' planned behaviors, such as albeit, internship, getting some certifications to have been regards as far away from entrepreneurship have positive relation with entrepreneurial intention and implementation. Entrepreneurship education and knowledge regarding start-ups given by Universities or private institutions should provide information to create imagination new venture business with spontaneity instead of giving intented contents concerning entrepreneurship when taking into consideration of result of hypothesis 2. In order words, entrepreneurship education to provide the self-efficacy is the right track for students.

Recently, medical devices for a smart health development and dissemination are becoming increasingly frequent use of devices and their's thermal stability, durability, the external splendors are required. Industrial demand for smart health medical devices uses high-functioning electrodeposition technology that expressed pearl-like feeling is rapidly increasing. Generally, pearl powder is added to electrodeposition pigment in order to form a coating which shows pearl-like feeling. On the other hand, the electrodeposition technology for the smart health medical devices uses a new method that can express pearl-like feeling without using pearl powder. In this study, we was tried to find out the most appropriate texture formation, the right dilution recipe. We've tried various ptoportions of pigments (ED-600, ED-600S, ED-MX, ED-M). As a result, we found out that ED-600 and ED-MX (15% solid) in appropriate concentration showed the best adherence rate. By several samples tests and experiments which include washing the fixed pigment in various temperature levels ($20{\sim}40^{\circ}C$) and drying, we were able to get the best results in drying condition of $180{\pm}10^{\circ}C$ and $30{\pm}5min$. The research showed that it is mush more competitive and cost effective to use the new method that produces natural pearl-like feeling on the surface than to add pearl powder to high-functioning electrodeposition pigment, which is a method that has been used for the smart health medical devices so far.

Using Digital Imaging and Communications in Medicine(DICOM) and a 3D medical imaging program, the characteristics of the external auditory canal(EAC) were compared. Using images of the ears of 63 different male and female subjects of varying age, this study measured and compared EAC transverse axis lengths, internal diameter circumferences, and upper and lower curvature angles. The findings of the study indicated differences in EAC shapes according not only to age and sex but also to the left and right of the same subject. A comparison between the sexes of the subjects (35 males and 28 females) indicated that, on average, the length of the EAC was 4.75mm longer in males. Based on the lower curvature angle, the interior side of the diameter circumference of the EAC was found to be reduced on average by 37.2% compared to the exterior side. Although the upper curvature angle was on average $25.7^{\circ}$ larger than the lower curvature angle, 4 subjects showed a larger lower curvature angle and large differences between the upper and lower curvature angles were observed in 8 subjects of the younger age group (4~14 years old). This indicated changes in EAC curvature shapes during growth. This study presents a method to raise safety and precision by comparing direct measurements taken through physical means and indirect measurements acquired from existing ear samples. This was possible due to technological developments in which 3D medical image representation technology creates images close to reality, and, through further development, this method is expected to be used for standardization research of EAC shapes.

Objective Many literature-based researches and clinical studies have been thus far reported of wha-byuong in Oriental medicine but acupunctural approaches to it have been little executed, which motivated this study to be conducted through acupunctural treatment. For that purpose, this study carried out incessant treatment on wha-byuong-having outpatients of this hospital who were suffering from gunhwa of wha in the saam acupuncture in order to inquire into the features of wha-byuong represented recently, and thereupon this got some intellect and knowledge out of clinical cases, which led this study to report them. Methodology Two wha-byuong outpatients were taken as subjects for this study who visited this hospital from January 10, 2002 through May 20, 2002. As for the contents of treatment and the administration of medicine, acupuncture utilized size $30{\times}50mm$ needles and the performance of treatment depended upon yuchim for 20 to 40 minutes at one time by means of simseunggyok (eumgok, sohae bo, taebaek, sinmun sa) on both right and left sides of the outpatients. As the case may be, sobu, baekhoi, and pungji were used at the same time. Bosa of simseunegyok took youngsu bosa. In order to evaluate treatment, symptoms were classified with diagrams into physical symptoms, dorgan symptoms, urinogenital organs symptoms, dermatological symptoms, cardiopulmonary symptoms, musculoskeletal symptoms, somnipathy symptoms, caput and sensual organ symptoms, psychomotor activity symptoms, and other symptoms, and then signs and marks were given to indicate the most objective values according to symptoms of the patients perceived in different sessions both prior and posterior to treatment. Conclusion As a result of having conducted treatment on two outpatients who visited this hospital for their wha-byuong from January 10, 2002 through May 20, 2002, conclusions were obtained, as follows: 1. Treatment depended very largely upon simseunggyok of the saam acupuncture, and as the case may be, baekhoi, pungji and sobu were utilized at the same time. 2. Much more effects were produced only when the patients had got rid of the causes of wha-byuong they had. Furthermore, the perceived seriousness of the symptoms presented had not been improved, regardless of their wha-byuong, 3. The main symptoms complained by the patients such as sangyeolgam, anxieties, impatience, hungmin, difficulty in breathing, cardiopalmus, insomnia, digestive troubles, etc. showed for the most part conspicuous therapeutical effects upon the symptoms of wha-byuong. In particular, a high degree of improvement was represented from melancholia and pyrexia.

As the number of the municipalities which have finished the phase I of their GIS system development projects increases, it is very natural that GIS system operation and maintenance rather than development itself has been a more important concern for these municipalities. It seems to me that these phenomena will be amplified as time goes by, and this is the right time for a series of proper guidelines regarding the GIS system maintenance to be supplied to the related municipalities. The subject which is called as 'GIS maintenance' is surely a very comprehensive area. It has been also founded that the necessity is widely agreed among the concerned people working for the municipalities which have already finished their first GIS projects. Nevertheless, it has been investigated that the studies done up to now in this area is in a very infant state from the quality and also quantity points of views. This paper, therefore, makes one of the very initial trials for the systematical GIS maintenance. Among the areas of GIS maintenance, the GIS database maintenance has been selected as the first trial area because of its natural characteristics of the basic element composing IS(Information System). For this, the present conditions of a variety of municipalities have been investigated as far as GIS maintenance is concerned, and the results are analyzed to produce a series of useful outcomes in terms of facing problems and accompanied plans. For each problem, a solution is defined and for each solution a detailed action plan (item) is derived. For each of the two kinds of GIS data given which are the fundamental map and the underground facilities map, an effective GIS data maintenance plan is suggested for the concerned municipalities.
