Indoor air quality (IAQ) is recognized as a byproduct of industrialization that took place in the 20th century. The great attention to IAQ has been gained since 1980s, and led to numerous research studies that have mainly made in the developed countries. As the development of residential environment in Korea enters in the process of qualitative growth, IAQ has viewed as one of the core issues in the society, and research in relation to IAQ has been implemented until now in the fields of engineering and medical science. It is widely known that the sources and effects of indoor air pollution have been various, and IAQ research with multidisciplinary approaches is required. Nevertheless, few research embedded into a socio-behavioral approach to identifying interventive measures of residents and analyzing their choices is made. The purpose of this study is to examine the use of an interactive measure of residents in apartments that is air purification with phytoncide available in the market, and to investigate their self-reported effects of the air purifying substance on sick building syndrome symptoms. This study utilizes a field experiment design with pre-test and post-test, and the experiment is conducted in a natural field setting. A total of 87 test subjects from 32 households with already sick building syndrome are drawn via internet, and the participation is solely voluntary. The participants receive and use the air purifying substance, and are asked to use it continuously for two weeks and identify their self-reported symptoms of before- and after-use. The research findings indicate that air purification using phytoncide is effective to alleviate their symptoms in relation to sick building syndrome. Also it is noted that the participants report that the use of the air purification causes the positive impacts on their daily life. Further research is needed that compares the group with only humidifier and evaluates the mid-term and long-term use of the air purification and its effects.

This study aims to examine the relationship between Serum Vitamin E and metabolic syndrome, which is a health risk, and to analyze the effect of Serum Vitamin E on the body. The analysis data were downloaded and used for the 7th 3rd (2018) data of the National Health and Nutrition Survey, and in this study, 944 men and 1,080 women were finally analyzed. For the analysis of the data, The chi-square test and t-test were used for the different values according to collected general characteristics and serum vitamin E, and the risk of metabolic syndrome was analyzed by regression, and Pearson correlation was used to confirm the correlation with each variable. Regression for Metabolic syndrome among the sub items and Serum Vitamin E showed that HDL-cholesterol was higher in the normal group than in the excess group (OR:1.042, CI:1.028-1.056), and triglycerides were significantly higher than in the normal group (OR:1.010, CI:1.009-1.012) (p<0.01). Therefore, it is proposed to develop nutrition and health programs suitable for the age of patients through this study.

The authors report a case of thoracic outlet syndrome in left side. Thoracic outlet syndrome is a collective term in which symptoms and signs are due to bony and soft tissue compression of the neurovascular bundle at the thoracic outlet. It is a rare case in neurosurgical field. So we had experienced one case of thoracic outlet syndrome which was improved by transaxillary approach for resection of first rib. The clinical features, diagnostic test, radiological findings, and operative technique are presented with review of literatures.

Sleep apnea syndrome is a common clinical disorder characterized by intermittent cessation of airflow at nose and mouth during sleep. The clinical significance of this syndrome is that it is one of the most common causes of excessive daytime sleepiness. It can also cause neuropsychiatric, cardiovascular, and cerebrovascular complications. The standard for diagnosis of sleep apnea syndrome is nocturnal polysomnography. Because polysomnography is a time-consuming and expensive test, many efforts have been made to replace polysomnography with a simpler system of monitoring, but no method has yet been approved as a definitive investigation method. The goals of treatment for this syndrome are to eliminate excessive daytime sleepiness and to reduce the risk of possible cardiovascular complications. Continuous positive airway pressure is the most definite and widely accepted treatment for achieving these goals. Other treatments such as surgical treatment, oral appliances, and behavioral therapy may be useful for selected patients who are mildly affected.

Cronkhite-Canada syndrome is a rare gastrointestinal polyposis syndrome with distinctive clinical features and endoscopic findings. Diagnosis can be challenging without suspicion, and the disease carries high mortality due to complications such as infection, gastrointestinal bleeding, and malignancies. This paper presents two cases of Cronkhite-Canada syndrome occurring after coronavirus disease 2019 (COVID-19) mRNA vaccination. Both cases exhibited typical clinical findings, including hypogeusia, onychodystrophy, alopecia, and weight loss. Typical polyposis in the gastrointestinal tract was confirmed through endoscopies. As symptomatic treatment did not improve the symptoms, corticosteroids were administered, and symptoms and laboratory test results improved immediately. The patients improved upon corticosteroids tapering. These cases illustrate typical presentations of Cronkhite-Canada syndrome and the course of the disease following corticosteroid treatment. Additionally, they suggest the possibility that Cronkhite-Canada syndrome may be triggered by COVID-19 mRNA vaccination.

This study involved a secondary analysis of 2016 Korean National Health and Nutrition Examination Survey data to identify the relations between metabolic syndrome, physical activity, and dietary patterns in Korean adults. The ${\chi}^2$-test, t-test, and logistic regression analysis of complex samples were conducted on the data of 3,352 subjects aged 19 to 64 years with metabolic syndrome. The prevalences of metabolic syndrome among men and women were 29.7% and 16.7%, respectively. In men, the high physical activity group showed a 0.8-fold increase in the likelihood of metabolic syndrome (OR=0.8, p=.038), and higher fat intake increased the risk of metabolic syndrome 0.98-fold (OR=0.98, p=.007). In women, the high physical activity group showed a 0.7-fold increase in the likelihood of metabolic syndrome (OR=0.71, p=.034), higher carbohydrate intake increased the risk of metabolic syndrome by 1.03-fold (OR=1.03, p<.001), and that higher protein and fat intakes reduced the risk by 0.96-fold (OR=0.96, p=.009) and 0.95-fold (OR=0.95, p<.001), respectively. The study shows that to meet the challenge presented by the increasing prevalence of metabolic syndrome, efforts are needed to screen for adults at risk of the metabolic syndrome by regular physical examination and to develop and provide intervention programs that involve regular high intensity physical activity and controlled carbohydrate, protein, and fat intakes.

We report a rare case of pronator teres syndrome in a young female patient. She reported that her right hand grip had weakened and development of tingling sensation in the first-third fingers two months previous. Thenar muscle atrophy was prominent, and hypoesthesia was also examined on median nerve territory. The pronation test and Tinel sign on the proximal forearm were positive. Severe pinch grip power weakness and production of a weak "OK" sign were also noted. Routine electromyography and nerve conduction velocity showed incomplete median neuropathy above the elbow level with severe axonal loss. Surgical treatment was performed because spontaneous recovery was not seen one month later.

The purpose of this study was to compare phonological awareness ability of students with Down Syndrome(DS) and typically developing children(TD). TD and DS were equal the reading abilities(reading recognition). The subject were 10 DS and 10 TD, and were examined by test of phonological awareness. The test of phonological awareness was composed according to phonological units(word, syllable, phoneme) and task types(deletion, discrimination, blending). The results obtained in this study were as follows: The total score of phonological awareness ability of DS were significantly lower than TD. And the score of phonological awareness ability according to phonological units and task types were significantly lower than TD. But both DS and TD performed better on phonological deletion and blending task than discrimination. TD and DS represented different correlation between task types and phonological units. This means that TD performed better on all types of tasks and phonological units than DS.

This paper proposes a new syndrome-testable design method for large MOSPLA's. In the conventional syndrome test method, the testing array circuit for testability is added but it has the defect that the circuit gives effect on the normal operation of the basic PLA circuit. Therefore, by adding the shift registers to the product lines of the basic MOSPLA's this defect is eliminated and the number of test patterns is decreased. In order to reduce the number of fault free syndromes to be predetermined, also, one output line, which is connected to all product lines is added. Therefore the number of output lines be observed is decreased. And the analytical method to compute fault free syndromes is presented. By unsing this method, the time and the effort to compute the syndromes are decreased.
