Hereditary tyrosinemia type I (fiunarylacetoacetate hydrolase deficiency) is an autosomal recessive inborn error of tyrosine metabolism that results in liver failure in infancy or chronic liver disease with cirrhosis, frequently complicated by hepatocellular carcinoma in childhood or early adolescence. Early detection of this condition is very important to early intervention for better prognosis of patients. Neonatal screening test using tandem mass spectrometry (MS-MS) is performed, and this method facilitates detection of the inborn error of tyrosine. For early treatment of tyrosinemia type I, phenylalanine and tyrosine restricted diet and NTBC (2-nitro-4-trifluoromethylbenzoyl-1,3-cyclohexanedione) for inhibition of succinylacetone production are recommended. We studied a 10-month-old Korean boy with tyrosinemia type I whose condition was not discovered earlier through conventional neonatal screening testing available in Korea. The patient presented hyperbilirubinemia, liver failure, bleeding tendency, colicky pain and skin melanin pigmentation in neonatal period. MS-MS made it possible to detect tyrosinemia type I and allowed immediate treatment of the patient. This was the first successful NTBC trial on tyrosinemia type I patient in Korea.

This study provides basic research for developing dress forms of women's wear making. This study compared the average body size of Korean women by investigating the shape, composition and size of 417 dress forms for pattern making, sold at Korean and international online malls. The results showed that Korean brands produced torso-type and torso-crotch-type (94.13%), torso-type was the most dominant type made by Japanese Ki and French St (${\geq}80%$), and all US Al products were whole-body-type. The most common used internal filler of the dress forms was urethane for South Korean companies and paper for Japanese Ki and French St. In most cases, cotton was used for outer materials. Alternatively, linen and rayon were used as outer materials. Al did not indicate the materials used for filler and outer layers. Additionally, the sizing system of dress forms was commonly presented as a Numeric type. In addition to Numeric type, Ki presented body type + usage and Al used character type. When the dress form size for the average bust size of each age group was evaluated, waist measurements were smaller than the corresponding bust measurements. Dress form was presented in the KS interval and was compared with the $mean{\pm}1{\sigma}$ interval of each age group. The majority of the dress forms produced in South Korea were for body shapes in their 20s.

This study started to diagnose the perception of 'public official' who are exposed to various tasks through public institutions in our daily work. In particular, among the public officials in various fields, public officials engaged in social welfare, health and welfare, and administration were diagnosed with the attitude of public officials to be equipped. For analysis, Q method, which is a qualitative research method, was used to diagnose and typify perceptions. First, the analysis results were derived into four types. In each type, shows the uniform distribution of public officials in health, administration and welfare fields and is named "General Type". is named as "Administrative Public Official Type" because the distribution of administrative civil servants is high. has a high distribution of welfare officers and is named as "Welfare Official Type". is composed mainly of public health officials, and is named as "Health Official Type". The public officials who are subject to this study should be responsible for "public service", that is, the unique work for the state and the public. In order to do this, we emphasize the accountability of the public officials themselves, and expect to expand into empirical research in future research.

In this study, the fishery status of the octopus pot fishery in the east coastal sea were investigated, and the fishing performance of each pot shape was compared and analyzed. The fishery status survey was conducted through listening surveys at Jukbyeon Port, Uljin Port and Pohang Daebo Port in Gyeongbuk Province, and the amount of fishing gear used, fishing method, size and loss of octopus pot fishery was investigated. On the east coastal sea, octopus is one of the commercially important fish stocks and is caught in inshore pots, inshore combos, inshore gillnets and offshore pots. Among these fishing methods, pot fishing yields the highest catch. The shape of the pot differs depending on the region. In Uljin (Jukbyeon Port and Hupo Port), Gyeongbuk, rectangular type net pots are mainly used, and in Pohang (Daebo Port) in Gyeongbuk, drum-type pots are mostly used. Enteroctopus dofleini accounts for more than 90% of the catch of octopus. For the octopus fishing performance test by trap type, three types of traps (rectangular pot, drum pot and cylinder pot) were used on the coastal sea of Pohang Daebo. As a result, the total catch by pot shape was shown in the order of rectangular-type pot > drum-type pot > cylinder-type pot. The catch of octopus, the target species, was in the following order: rectangular-type pot > drum-type pot > cylinder-type pot. Such result shows a significant difference (Mann-Whitney test, p<0.05).

Background: Non-cardiac chest pain (NCCP) is a common patient complaint imposing great costs on the healthcare system. It is associated with psychological factors such as depression. The aim of the present study is determining depression predictors in NCCP patients. Methods: The participants of this cross-sectional study were 361 NCCP patients. Patients filled out questionnaires concerning their sociodemographic, lifestyle, and clinical factors (severity of pain, type D personality, somatization, cardiac anxiety, fear of body sensations, and depression). Results: Based on multiple ordinal logistic regression, lack of physical activity (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.09-2.87), sleep quality (OR, 2.98; 95% CI, 1.15-7.69), being a smoker (OR, 1.33; 95% CI, 2.41-4.03), present pain intensity (OR, 1.08; 95% CI, 1.05-1.11), type D personality (OR, 2.43; 95% CI, 1.47-4.03), and somatization (OR, 1.22; 95% CI, 1.15-1.3) were significant predictors of depression in NCCP patients. Additionally, multiple linear regression showed that being unmarried (β = 1.51, P = 0.008), lack of physical activity (β = 1.22, P = 0.015), sleep quality (β = 2.26, P = 0.022), present pain intensity (β = 0.07, P = 0.045), type D personality (β = 1.87, P < 0.001), somatization (β = 0.45, P < 0.001), and fear of bodily sensation (β = 0.04, P = 0.032) increased significantly depression scores in NCCP patients. Conclusions: Physicians should consider the predictors of depression in NCCP patients which can lead to receiving effective psychological consultations and reducing the costs and ineffectual referrals to medical centers.

Posterior disk displacement (PDD) of the temporomandibular joint (TMJ) is a rare condition and most descriptions of TMJ PDD are about the adhesion of superior TMJ in which the position of disk is relatively posterior to anteriorly translated condyle in open mouth position. However, there have been reports about truly posteriorly positioned disk to the condyle in closed mouth position. This type of PDD has been classified into three subtypes-thin flat disk type, grossly posterior displaced disk type, and perforated disk type. Here, we report two rare cases of TMJ PDD, one with thin flat disk and one with perforated disk. Its possible etiology, pathogenetic mechanisms, related signs and symptoms, differential diagnoses, and treatments were reviewed and discussed.

The purpose of this research were to classify college women's clothing shopping orientation and analyze the predictable variables of impulse buying. The results of this research were as follows ; 1. Clothing shopping orientation was classified leisure pursuit, economic, careful and name brand preferring shopping. With reference to leisure pursuit and economic shopping, they were classified into four types, low shopping involved shopping type, economic shopping type, leisure pursuit shopping type, and high shopping involved shopping type. The low shopping-involved and the economic shopping types made much of planned buying. The planned impulse buying, reminder impulse buying, fashion oriented impulse buying and pure impulse buying were highly evaluated in the high-involved and the leisure pursuit shopping types. 3. The high shopping-involved and leisure pursuit shopping types were more likely to do impulse buying than low shopping-involved and the economic shopping types. 4. The most important factor for the four groups was design. Quality, color, utility were followed by design. 5. Impulse buying behaviors of four groups could be predicted by the information source and the marketing stimulus buying.

A PID type fuzzy Controller is proposed based on a crisp type model in which the consequent parts of the fuzzy control rules are functional representation or real numbers. Using the conventional PID control theory, a new PID type fuzzy controller is developed, which retains the characteristics of the conventional PID controller. An advantage of this approach, is that it simplifies the complicated defuzzification algorithm which could be time consuming. Computer simulation results have shown that the proposed PID fuzzy controller has satisfactory tracking performance.

Tolerance design has been identified as an important research area and a number of models have been proposed in the literature. This paper investigates the effect of limited capacity on tolerance design for products with nominal-the-best type (N-type) quality characteristics. The model is developed under the assumption that the reprocessed and nonreprocessed items are produced by the same manufacturing process and therefore their quality characteristics are identically and independently distributed. Profit models are constructed which involve four price/cost components; selling price, cost incurred by imperfect quality, reprocessing and quality inspection costs. Methods of finding the optimal tolerance limits are presented, and a numerical example is given. Sensitivity analyses are also performed to study the effect of a process standard deviation on this model.
