Aim of this study was to investigate whether middle school students with different body mass index (BMI) and sex were different in their lifestyles and nutrient intake. Middle school students (n=408) in Gyenggi-do were participated in this stsudy. Height, weight and BMI of female students were 159.6㎝, 50.4㎏, and 19.7 ㎏/㎡, and those of male students were 165.5㎝, 57.7㎏ and 20.9㎏/㎡, respectively. Classified by BMI, there were 30% underweight, 51% normal, and 18.9% overweight. Reading time of underweight group was significantly shorter than those of overweight. More underweight students thought themselves healthier and had more appetite than overweight subjects. Male students used computer significantly longer and ate more on time, but had more unbalanced diet than females. Male students consumed more calorie, protein, vegetable protein, vegetable fat, carbohydrate, sodium, vitamin B1. Intakes of fiber and calcium were lower than the Dietary Reference Intakes for Koreans for that age group. Our results suggested that students had meal not on time, unbalanced diet, and meal too fast. Intakes of protein, fat, and sodium were higher, but intakes of calcium and fiber were too low. Those may cause serious health problem. Thus, students and health care providers should recognize the problems and develop education programs to help students to keep proper life style and eating habits.

Restrictions on Property Rights: Benevolent Intent, Disruptive Outcome - The Conundrum of South Korea’s Chonse(전세) Reform

Yong-Shik Lee 한국제도∙경제학회 2021 제도와 경제 Vol.15 No.1

본 논문은 최근 전세 개혁이 주거 시장에 미친 영향에 관해 논의한다. 전세는 한국에 서만 발견되는 독특한 주택임대 제도이다. 전세계에서 찾아보기 힘든 독특한 제도인 전세는 몇가지 경제적인 이유로 인해 존속해 왔으나 최근의 여러 상황으로 인해 그 미래는 불투명하다. 최근 한국, 특히 서울에서의 주거 비용은 급속히 높아졌으며, 이로 인해 세입자들의 비용 부담이 가중되어 왔다. 이에 대응하여 한국 정부는 논란이 많은 법 개정을 통해 전세금을 포함한 세입자의 집세 증액에 관해 연간 일정한 상한선을 도입했으며, 주거 시장을 안정시키고 세입자들의 편의를 위해 1회에 한해 의무적으로 전세계약을 연장하도록 했다. 그러나 이러한 법제 개혁은 예기치 않은 주거 시장의 혼란과 전세 물량의 부족을 초래했다. 본 논문은 최근 전세 개혁의 사회경제적 영향을 분석하고, 최근에 수립된 “법개발학 일반이론”(General Theory of Law and Development)을 도입하여 전세에 관한 법제 개혁이 예상치 않은 결과를 초래한 이유 를 분석한다. This article discusses South Korea’s recent property law reform (affecting “Chonse”) and its unintended impact on the housing market. Chonse is a unique and prevailing residential lease found only in South Korea. Under a Chonse contract, a lessee makes a one-time deposit with the lessor, the amount of which equates to a substantial portion of the property value; in exchange, the lessee is permitted to lease the property free of rent and reclaim the deposit on the expiration of the lease. This unique leasehold system has existed for several economic reasons. Recent developments render the future prospect of Chonse uncertain; housing costs have been rapidly increasing in South Korea, particularly in the City of Seoul, generating financial pressure on lessees. In response to this price hike, the South Korean government has undertaken controversial law reform that imposes a cap on annual rent increase, including Chonse deposit amount, and also mandates one-time renewal of residential lease for additional two years, in efforts to assist lessees and stabilize the housing market. This law reform, however, has caused unintended disruption in the housing market and a shortage of residential properties available for Chonse. The author has previously introduced Chonse in a co-authored article and examined its historical origin, legal elements, and future prospects. This article, building on the author’s previous work, analyzes the socioeconomic impact of Korea’s recent Chonse reform. The article adopts the “General Theory of Law and Development” and explains why the law reform has resulted in unintended outcomes. The article cautions against the (well-intended) attempt to restrict property rights resulting in disruptions in the housing market and increasing costs for Chonse lessees.

( Su Yong Jeon ),( Woo Hyuk Yun ),( Ha Na Hyun ),( Hee Yung Chang ),( Hyung Keun You ),( Sung Hee Pi ) 조선대학교 치의학연구원 2015 Oral Biology Research (Oral Biol Res) Vol.39 No.1

Purpose: Since endosseous implants are used for the treatment of various types of tooth loss, they are considered a primary therapeutic options. Many studies regarding implant survival rates have been published. However, there have been few long-term studies on implant survival rate in Koreans. Therefore, the aim of this study was to examine implant survival rate for 8 years as well as identify potential risk factors for failure. Materials and Methods: The present study included 535 implants in 332 patients at the Department of Periodontology of Wonkwang Dental Hospital. By means of a chart review, 1) implant site, 2) age and sex of patients, 3) diameter and length of placed implant, 4) advanced technique at recipient site, 5) periodontal treatments before implant therapy, and 6) systemic diseases such as diabetes mellitus, hypertension, or osteoporosis were recorded. The effects of evaluated variables on implant failure were analyzed using chi-square test. Statistical significance was accepted at p<0.05. Results: The present study showed an implant survival rate of 97.76%. Overall, 12 of 535 (2.24%) implants were explanted. Two explanted implants were in the maxillary anterior area, five were in the maxillary posterior area, and five were in the mandibular posterior area. The average time from placement to explantation was 11.92±15.30 months. None of the investigated factors was significantly associated with implant failure (p>0.05). Conclusion: Survival rate in this study was 97.76%. Despite the lack of significant association between implant failure and associated factors, there are potential risk factors. Cautious diagnosis and treatment planning are needed.

Poster Session : PS 1464 ; Infectious Diseases : A Case of Brain Abscess Caused by Aggregatibacter Aphrophilus in Korea

( Yong Duk Jeon ),( Jung Ho Kim ),( Hea Won Ann ),( Jin Young Ahn ),( Sun Bean Kim ),( Nam Su Ku ),( Sang Hoon Han ),( Jun Yong Choi ),( Dongeun Yong ),( Kyungwon Lee ),( June Myung Kim ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Backgrouond: Aggregatibacter aphrophilus (A. aphrophilus) is a gram negative, capnophilic, fermentative, coccobacillus that is occasionally isolated from patients with infective endocarditis. It has also been reported to cause brain abscess, empyema, meningitis, osteomyelitis and joint infection. Herein we report the first case of brain abscess caused by A. aphrophilus in Korea. Case: A 26-year-old man visited hospital for a headache during three weeks. He presented fever, nausea and vomiting for three days. His blood pressure was 108/69 mmHg and his body temperature was 36.9 ℃ at that time. His past medical history was unremarkable. Brain magnetic resonance imaging (MRI) was performed and revealed the 4 cm sized abscess in the frontal lobe with profound perilesional edema and subdural empyema. He received empirical intravenous antibiotic treatment with ceftriaxone 2.0 g every 12 hours, vancomycin 1.0 g every 12 hours and metronidazole 500 mg every 8 hours. On the 4th hospital day, he had decompressive craniectomy and drainage of the abscess. On the 8th hospital day, A. aphrophilus was identified in the culture of abscess. Vancomycin and metronidazole were discontinued and ceftriaxone monotherapy was maintained because it was susceptible to the 3rd generation cephalosporin. On the 11th hospital day, transthoracic echocardiography was performed, but there was no evidence of endocarditis. After a eight-week course of intravenous ceftriaxone therapy, follow-up MRI revealed almost resolved abscess. Intravenous ceftriaxone was changed to oral cefixime 100 mg every 12 hours and he was discharged. He treated with oral cefixime for 12 weeks in outpatient clinic until the complete resolution of brain abscess on MRI.

<P>The incidence of <I>Clostridium difficile</I> infection is increasing worldwide, and its severity and resulting mortality are also on the rise. Metronidazole and oral vancomycin remain the treatments of choice, but there are concerns about treatment failure and the appearance of resistant strains. Furthermore, antibiotic therapy results in recurrence rates of at least 20%. Fecal transplantation may be a feasible treatment option for recurrent <I>C. difficile</I> infection; moreover, it may be an early treatment option for severe <I>C. difficile</I> infection. We report a case of severe <I>C. difficile</I> infection treated with fecal transplantation using a nasoenteric tube during an initial episode. This is the first reported case of fecal transplantation using a nasoenteric tube during an initial episode of <I>C. difficile</I> infection in Korea.</P>
