Leisure constraints mean the factor to constrain individual's leisure activity. Leisure constraints are composed of interpersonal constraints, interpersonal constraints and structural constraints. The purposes of this study are to show that intrapersonal leisure constraints have a strong effect on leisure preference, and leisure constraints are sequential and hierachical process. Intrapersonal constraints effect on leisure constraints in first step. And then interpersonal constraints and structural constraints effect on leisure participation. Those three leisure constraints are all linked together and come out step by step. Regarding adults as a population, who are more than 20-year-old and live in Seoul, 9 dongs were chose after dividing into upper and lower classes according to the value of their residence. The questionnaire consists of 4 parts: intrapersonal constraints, interpersonal constraints, structural constraints, and demographic characteristics. Results of this paper is that people who have strong intrapersonal constraints normally have problems caused from social structure. Intrapersonal constraints and structural constrains come out not seperately but together. Then, it can be said that structural constraints have an influence over intrapersonal constraints. So, it's necessary to solve structural problems to increase preferences and participations of them.

This study investigates differences in demographic characteristics, shopping orientation, perceived risk, and satisfaction after purchase among consumer types. This study classifies consumer types according to their channel transition behaviors between the online and offline channels with a focus on the steps of information research and buying decision in buying decision-making process. The four consumer groups are as follows: off-off type (offline research-offline purchase), on-on type (online research-online purchase), on-off type (online research-offline purchase) and on/off-off type (online and offline research-offline purchase), off-on type (offline research-online purchase) and on/off-on type (online and offline research-online purchase). Data were collected from adults over 20 years old who had bought clothes within one year. The questionnaire was carried out from July, 2019 using a professional internet research panel; in addition, 500 sets of useful data were analyzed by descriptive statistics, factor analysis, reliability analysis, chi-squared test, ANOVA and Duncan-test using SPSS 21.0. The findings showed significant differences among the classified consumer groups for consumer demographics, shopping orientation, perceived risk, and purchase after satisfaction. The results imply that consumers show a variety of channel transition behaviors based on demographic variables, shopping orientation, and perceived risk. Understanding and adapting to consumer purchase behaviors will allow company distribution channels to be effectively managed and eventually increase consumer satisfaction as well as company sales volume.

Radioactive iodine treatment has been widely used for nearly 50 years in the treatment of thyroid cancer to ablate residual thyroid tissue after thyroidectomy and to treat metastatic disease. Leukemia is a rare complication associated with the radioactive iodine therapy. The occurrence of leukemia is known to be related to the cumulative dosage of I-131 more than 37 GBq (1 Ci) and also associated with the intervals of less than 12 months between the repeated doses. We report a case of a 52 year-old female patient with papillary cancer of thyroid who developed acute myelogenous leukemia after the total 20.4 GBq (550 mCi) of I-131 therapy over 3.2 years and palliative radiation therapy (3000 cGy) due to multiple bone metastasis of papillary cancer.

It is well known that many patients with trigeminal neuralgia suffer from electric shock-like stabbing pains. The pain can be triggered by nonnoxious stimuli such as touching of the face, chewing, talking or swallowing. This 62 year old woman was urgently admitted to the internal medicine department due to abdominal distention and severe general weakness. She has suffered characteristic violent pain triggered by chewing and swallowing for little over 4 years. This resulted in poor oral feeding for prolonged period which left her severely debilitated. The large amount of ascites that developed 20 days before admission and extreme emaciation forced her to bed rest. She also suffered from Herpes Zoster. After medical treatment to improve liver function and severe pain was persisted, the patient was referred to our department for control of pain. We performed right mandibular block with 1% dibucaine 0.4 ml and the effect was excellent. After the pain had subsided, patient was able to take meals more comfortably and improved liver function returned.

Coarctation of the aorta is rare condition among the congenital cardiovascular defects in Korea. We experienced one case of coarctation of the aorta [postductal type], which was successfully corrected with Dacron graft. This 20 year old man was admitted to our hospital for evaluation of hypertension in the upper extremities and frequent occipital headache of 2 month duration. On physical examination, grade II systolic murmur was heard over the apex and mid back, but thrill was not palpable. Blood pressures were measured at both extremities, its values were 190/70mmHg. in the arms and 120/60mmHg in the legs. Routine chest roentgenogram showed the dilated left subclavian artery high on the left mediastinal border and associated with left ventricular prominence, but notchings of lower border of rib was not seen. Electrocardiogram also showed left ventricular hypertrophy. Final Pre-operative diagnosis was made by the aortic catheterization and aortography, which showed the typical configuration of postductal type of coarctation with poststenotic dilatation of aorta. Under the moderate hypothermia by surface cooling, coarcation was resected 3.5cm in length and then Dacron graft was inserted. After prosthetic correction, blood pressures were recorded 120/60mmHg in arms and 160/120mmHg in legs. The post-operative course was uneventful.

Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. A 20-year-old Asian Indian female presented to our Oral and Maxillofacial unit with a lump on the left side of her forehead for 1 month. Local examination revealed a $2.5{\times}3.0cm^2$, well circumscribed swelling over the left para median region that was firm to doughy and non-tender. There was no other significant finding on general examination. Excisional biopsy of the lesion was performed, followed by histopathologic processing. The general etiology, pathogenesis, clinical presentation, differential diagnosis, clinical course, prognosis, treatment, and prevention have been discussed in line with the recent modalities of diagnosis and treatment of CLH. Due to the overlapping clinical and histological characteristics of CLH with many other lesions, it is important to consider this lesion in the differential diagnosis of cutaneous lesions.

This study analyzes relevant data based on the mid-sized rental unit. It focuses on how we can set up appropriate mid-sized rental unit plan as its supply has been accelerated over time. The questionnaires used in this study cover a series of categories including site environment, unit plan, neighborhood, economy, and management. The 342 respondents are from the 3-year old apartments at Cheongju. The key findings are as follows. 1) As the average indices including number of family, life cycle, and income under the survey are different in terms of the rental unit sizes between 20 and 30 pyeongs. 2) In general, residents present comparatively high level of satisfaction in terms of residential environments. Their evaluation on the site environment unit plan, and neighborhood is around the average. In contrast, the economic and management efficiency categories are under the average. This study suggests residential guidelines should be derived from tenant differentiation policies dealing with diverse socio-demographic characteristics and satisfaction level. 3) In terms of improvement priority, residents present, higher preference on the management system and site environment. This study advises to establish an appropriate alternative to guarantee effective tenant participation. Considering the lower satisfaction level in the green space, common facilities, and resting space, this study also urges to secure quality control for desirable planning of the mid-sized rental apartments.

Forty two patients with chronic constrictive pericarditis, who were admitted to the Yonsei University College of medicine over a period of 18 years from January, 1970 to August, 1988, were analyzed retrospectively. Mean age of the patient was 33.5 year ranging from 6.8 to 60 years old. Male to female ratio was 1.3 to 1. Twenty-one cases [50%] were tuberculous origin [based on either associated pulmonary tuberculosis and/or caseous necrosis in thickened pericardial specimen] and 17 cases [40.5%] were idiopathic [non specific chronic inflammatory change was considered to be idiopathic]. Dyspnea on exertion was evident in 30 cases [71.4%] and abdominal distention in 21 cases [50%]. On physical examination, hepatomegaly [83.3%], neck vein distention [54.8%], distant heart sound [47.6%] and ascites were found. Thirty-nine patients showed low voltage of QRS and/or T wave flattening or inversion on EKG. Thirty-one cases had undergone cardiac catheterization which showed data compatible with chronic constrictive pericarditis. Midsternostomy group [n=15] had shown the most remarkable CVP decline [12.20 mmHg] as compared with bilateral submammary incision group [n=25, 8.96 mmHg] and left thoracotomy group [n=2, 7.75 mmHg] but difference was not significant statistically There was four early death among 42 patients [9.5%] including 3 cases of left ventricular failure and one cardiac tamponade. Main postoperative complications were wound infection [6 cases] and arrhythmia [3 cases]. Follow-up of 24 patients [mean; 55.3 months, ranging from 2 months to 155 months] revealed good functional status.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign, fibro-osseous variant of ossifying fibroma. It exhibits short-term rapid growth and has a high recurrence rate. Herein we describe a case of JPOF of the maxilla that was treated via complete excision utilizing an intraoral approach with immediate reconstruction using an iliac bone graft, in conjunction with a comprehensive review of the literature. A 20-year-old man presented with a mass on his right cheek that he reported had been growing over the last 10 months. In that cheek he had noticed fullness and experienced pressure, tenderness, and fluffiness, with no other ophthalmic or dental symptoms. After clinical, radiological, and histological examinations, the diagnosis was confirmed as JPOF. Surgical excision was performed, followed by immediate reconstruction with an autologous iliac cortical and cancellous bone graft harvested from the right iliac crest under general anesthesia. Good cicatrization of the intraoral surgical wounds and right iliac crest were evident. He was monitored for 6 months after the surgery and exhibited appropriate midfacial contour. There were no signs of recurrence or complications.
