Korea's medical law prohibited medical advertisements in principle and permitted them on an exceptional cases. However, the decision of the Constitutional Court of 20005. 10. 27. 20003 Heonga 3, it was changed to a negative system which allows advertisements in principle and restricted only exceptionally. Dramatic increase of medical advertisements was made after that and many argued more deregulation because there was actually heavy regulations. In particular, there is almost no actual regulation on the article type advertisement due to the reason of protection of the freedom of press, media and occupation. However, there may be an unjust result if a specific article or specialists' opinion is made using a newspaper, broadcasting or magazine as a form of article type advertisement to specific medical specialists or medical institution or medical treatment method that falsifies consumers or makes consumers confused by unjust medical expectations or reliability, that also deteriorates just competition and that causes the misrecognition of consumers. In fact, there were actual damages of article type advertisements on the eye whitening surgery not long after the transfer to a negative system of medical advertisements. Victims raised a medical proceeding against the doctor who carried out the surgery, but there is actually no systematic warranty except for the indemnity request. Thus, this case demonstrated a vulnerable result of a negative system. As such, it is problematic that there is no proper regulations defined in the current law and regulations because of the reason of the protection of the freedom of press, publication and occupation despite damages of such article type advertisements. Accordingly, it is urgent to apply the current prevention regulations on the article type advertisements strictly, and to set up specific regulations.

In Korea, the construction company has provided houses through apartment sales system. Residents have obtained a variety of information about their future house by visiting a sample house called "the model house" before they purchase home. Advanced technology such as web-based VOD or Virtual Model in recent years has gradually replaced those built environment. In 2009, the Ministry of Land, Transport and Maritime Affairs announced the restraint to the construction of sample houses. Instead, they highly recommended a Virtual Model House as an alternative solution. This study aimed to propose how to design the user-oriented virtual model house through the experiment and survey research. The 3D virtual model house of 85m$^2$ apartment was built and presented by two types (Type A: Bird's Eye View, Type B: Walk through View) on the web page. The subjects evaluated presence, spatial perception and cognition, and usability of each type after exploring them. The results are as follows. (1) The subjects' evaluation of presence showed Type B has more negative effects than Type A such as feeling dizzy or tired even if their values were not so high. (2) The subjects perceived and cognized both types of virtual model house more realistic for the expression of volume of space, the size of opening, and the arrangement of furniture than that of wall finishes and materials. (3) The usability of Type A was significantly higher than that of Type B.

Objectives : Evidence supporting the cold-heat symptom and sasang constitution type, which are diagnostic items of traditional Korean medicine, is needed to manage sleep disturbances, which is a typical symptom of mibyeong (subhealth). This study examined the association between each cold-heat symptom and sleep disturbances according to each sasang constitution type. Methods : This research was a cross-sectional study of 5,793 subjects from the Korean Medicine Data Center (KDC) community cohort survey. The association between each cold-heat symptom and sleep disturbances was analyzed by logistic regression analysis adjusted for several demographic variables. Subgroup analysis was then performed for each type of sasang constitution. Results : The soeum and soyang types were 1.53 and 1.26 times more likely to have sleep disturbances than the taeum type. Sleep disturbances were associated with 'coldness of the abdomen', 'watery mouth' in the cold domain items, and 'body feverishness', 'flushed face and eye', 'thirst', and 'scanty dark urine' in the heat domain items. The soeum and soyang types were 1.55 and 1.39 times more likely to sleep less than five hours per night than the taeeum type. In addition, the associations of those showed a different pattern for each sasang constitution type. Conclusions : Sleep disturbances are associated with specific cold-heat symptoms, and the associated cold-heat symptoms differ according to the sasang constitution type. These results may help traditional medicine specialists select customized interventions for patients with sleep disturbances.

Objective: To investigate the distribution, side involvement, phenotype, and associated anomalies of Korean patients with craniofacial clefts (CFC). Methods: The samples consisted of 38 CFC patients, who were treated at Seoul National University Dental Hospital during 1998-2018. The Tessier cleft type, sex, side involvement, phenotype, and associated anomalies were investigated using non-parametric statistical analysis. Results: The three most common types were #7 cleft, followed by #0 cleft and #14 cleft. There was no difference between the frequency of male and female. Patients with #0 cleft exhibited nasal deformity, bony defect, and missing teeth in the premaxilla, midline cleft lip, and eye problems. A patient with #3 cleft (unilateral type) exhibited bilateral cleft lip and alveolus. All patients with #4 cleft were the bilateral type, including a combination of #3 and #4 clefts, and had multiple missing teeth. A patient with #5 cleft (unilateral type) had a posterior openbite. In patients with #7 cleft, the unilateral type was more prevalent than the bilateral type (87.0% vs. 13.0%, p < 0.001). Sixteen patients showed hemifacial microsomia (HFM), Goldenhar syndrome, and unilateral cleft lip and palate (UCLP). There was a significant match in the side involvement of #7 cleft and HFM (87.5%, p < 0.01). Patients with #14 cleft had plagiocephaly, UCLP, or hyperterorbitism. A patient with #30 cleft exhibited tongue tie and missing tooth. Conclusions: Due to the diverse associated craniofacial anomalies in patients with CFC, a multidisciplinary approach involving a well-experienced cooperative team is mandatory for these patients.

The adiponectin gene is known to be involved in the regulation of energy homeostasis involving food intake, carbohydrate and lipid metabolism. Human adiponectin gene polymorphisms have been recently reported to be associated with obesity, insulin sensitivity and the risk of type 2 diabetes. The present study was carried out to investigate the porcine adiponectin gene as a candidate gene for fat deposition and carcass traits. A mutation of A178G of the porcine adiponectin gene that resulted in substitution of the amino acid Isoleucine to Valine was identified. AcyI PCR-RFLP was used to detect the polymorphism of the genotypes in five different pig populations (Large White, Landrace, Duroc, Chinese breeds Meishan and Qingping). The A allele frequency was significantly higher among subjects from Chinsese lard type breeds, while the G allele was the only one present in those from Western lean type breeds. To determine if there was an association of the polymorphism with phenotypic variation, the mutation was tested in 267 pigs of the "Large $White{\times}Meishan$" F2 resource population. The results of association analyses showed significant associations of the genotypes with fat deposition and carcass traits. Allele G was significantly associated with increase in loin eye height, loin eye area and lean meat percentage and bone percentage, and decrease in fat mean percentage, ratio of lean to fat, shoulder fat thickness, 6-7 rib fat thickness, thorax-waist fat thickness and buttock fat thickness. The substitution of A178G (Ile60Val) happened to be located at amino acid 60 in the collagenous domain of porcine adiponectin which might affect the association into higher-order structures, and accordingly affect the posttranslational modifications and optimal biological activity of the multimeric forms. The identified functional polymorphism provides new evidence of adiponectin as an important candidate gene affecting fat deposition and carcass traits in pigs.

본고에서는 조선후기 사설시조에 나타난 여가활동의 양상을 분석하여 우리민족의 여가문화의 한 단면을 살펴보고자 하였다. 조선조 사설시조에 나타난 여가활동은 기분전환과 유홍지향, 건강관리와 신체회복, 자기계발과 생활변화 등의 양상으로 주제화되어 작품에 나타나고 있다. 기분전환과 유흥지향의 시조는 소년시절의 여가활동을 주로 표출하고 있으며, 건강관리와 신체회복의 시조는 노년시절의 여가활동을 주로 표출하고 있다. 그리고 자기계발과 사회적응의 시조에는 소년시절과 노년시절의 여가활동이 함께 나타나는 현상을 보여주고 있다. 이처럼 사설시조에 나타난 여가의 양상은 크게 소년시절의 여가활동과 노년시절의 여가활동으로 나누어질 수 있다. 그런데 소년시절의 여가활동은 건전한 여가와 위험한 여가가 함께 어우러져 있으나, 노년시절의 여가활동은 건전한 여가가 대부분이라 할 수 있다. 사설시조에 나타난 가장 완전한 여가활동으로는 개인의 기분전환, 신체회복, 자기계발, 창조정신 등의 내용이 함께 어울러져있어야 한다고 할 수 있다. 주5일 근무제가 시행되는 2004년, 현재를 살아가는 우리들은 옛 시조에 나타난 여유와 느림의 미학에 바탕을 둔 선조들의 여가활동을 음미해봄으로써 심신이 건강한 맛과 멋의 여가활동을 함께 즐겨야 할 것이다.

Hydrocepbalus may be an acquired or a congenital condition. We have studied the macroscopic and microscopic changes in the hydrocephalus of an inbred Sprague-Dawley rat at postnatal week 8. The animal suspected with the hydrocephalus showed clinical syndromes such as depression, severe ataxia, eye abnormalities, dome-shaped head, and persistent fontanelle. With the postmortem examination, the suspected animal was clearly revealed as a severe internal hydrocephalus. In this animal, severe ventriculomegaly was limited to the third and lateral ventricles, and cortical thining was most apparent in the parieto-occipital region. With the routine histological examination, brain tissue showed aqueductal obstruction, thinning of the cerebral cortex, severe ependymal damage, subependymal edema, damage of choroid plexus of fourth ventricle, enlarged cortical vessels, and expanded ventricles. Aqueductal obstruction was observed with the appearance of simple stenosis at the level of rostral colliculus. Subsequently, the other structures of brain such as septal nucleus, caudate nucleus, and hippocampus etc. were abnormally reconstructed by hydrocephalus. This study suggests that the hydrocephalus can be taken place by primary aqueductal obstruction and this type of hydrocephalus is classified as uncommunicating type. Though the mechanism of aqueductal obstruction is not clear, the morphological studies of this case may be helpful for the further study of hydrocephalus.

The formation degree of sustain (ITO pattern) determines the quality of a PDP (Plasma Display Panel). Thus, in the present study, we attempt to detect 100% of the defects that are larger than $30{\mu}m$. Currently, the inspection method in the PDP manufacturing process is dependent upon the naked eye or a microscope in off-line mode. In this study, a prototype inspection system for PDP ITO patterned glass is developed. The developed system, which is based on a line-scan mechanism, obtains information on the defects and sorts the defects by type automatically. The developed inspection system adopts a multi-vision method using slit-beam formation for minimum inspection time and the detection algorithm is embodied in the detection ability. Characteristic defects such as pin holes, substances, and protrusions are extracted using the blob analysis method. Defects such as open, short, spots and others are distinguished by the line type inspection algorithm. It was experimentally verified that the developed inspection system can detect defects with reliability of up to 95% in about 60 seconds for the 42-inch PDP panel.

The aim of this study is to investigate the effects of the muscle mass and fiber number on post-mortem metabolic rates and pork quality. Carcass traits, muscle fiber characteristics, and type of fiber composition were evaluated using a sample of 200 cross-bred pigs. The muscle mass was divided into two groups according to carcass weight and loin-eye area measurements (heavy or light). In addition, the muscle histological characteristics were divided into two groups according to the muscle fiber density and total number of muscle fibers (high or low). All the carcass traits were significantly different in the muscle mass groups. Increasing weight significantly affected the cross-sectional area (CSA) of all fibers. The low group, which had a low muscle fiber number indicating a larger CSA of fibers, and especially the heavy-low group had the highest CSA levels of fibers. The fiber number percentage and the area percentage were significantly different in the groups categorized by fiber number. The heavy-high group indicated a normal rate of pH decline and the R-value. In addition, pigs with a heavy muscle mass and high muscle fiber number indicated normal drip loss, lightness, and protein denaturation. The present results suggest that increasing the total muscle fiber number has a beneficial effect on increasing the muscle mass without deteriorating the meat quality.
