Objective: The purpose of this study was to identify dietary factors related to infertility in Korean women through a case-control study. Methods: The case group was composed of 236 women who had been diagnosed as infertility in hospital. The control group of 181 healthy women with children were recruited from local immunization centers. Socio-economic status, medical history, dietary intakes using food frequency questionnaire and stress were surveyed by interview. Anthropometric measurements were made and the causes of infertility were identified through medical records. Fasting blood samples were taken from subgroup of the subjects. Results: The mean age of infertile and control groups was 31.1 and 32.4 years, respectively and the difference was statistically significant. The mean Body Mass Index of infertile women was not significantly different from control women, however, Waist/ Hip Ratio and Triceps Skinfolds Thickness were significantly lower in infertile women than in control women. The dietary intake status was generally satisfactory in both groups. The intakes of energy, protein, fat, carbohydrate, retinol, vitamin B2 and niacin were lower in infertile women than in control women. The infertile women also showed lower intakes of animal foods. No differences were found between two groups in serum concentrations of albumin, hemoglobin, Fe, TIBC, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, C3, IgA, IL-2, however, infertile women showed higher levels of Zn and IgG. The stress score was higher in infertile women. Conclusions: From the results of this study, dietary factors and nutritional status do not seem to be directly related to infertility. However, the intertile women have lower nutrient intake and lower body fat content than control women. Further researches are needed according to the causes of infertility for long term to establish the relationship between dietary factors and infertility.

The glandular odontogenic cyst is an uncommon odontogenic cyst as a distinct entity. We reviewed a series of 7 glandular odontogenic cysts of the jaws experienced between 2003 and 2006 at the department of Oral and Maxillofacial surgery, Chosun university. The study group consisted of 3 females (42.9%) and 4 males (57.1%), with an age range of 31 to 75 years and mean age was 58.6 years. The maxilla was involved in 5 cases (71.4%) and the mandible in 2 cases (28.6%). Three cases involved impacted tooth. Clinically 6 cases showed swelling and tenderness. All the lesion presented well-defined unilocular radiolucent lesion radiographically. Provisional clinical diagnosis was varied, incisional biopsy was done in 1 case. Histopathologically, those were lined by non-keratinized stratified epithelium and thickened epithelial segments (plaques) are seen within the lining epithelium. And epithelial lining contains eosinophilic cuboidal type cells, mucous cells and mucin pools in microcystic areas are identified. All cysts were treated by enucleation. All cases are not recurred during follow up period.

The purpose of this study was to evaluate effect of platelet rich plasma on the treatment of Grade II furcation involvement, with and without porous resorbable calcium carbonate($Biocoral^{(R)}$)in humans by digital subtraction radiography. 15 teeth(control group) were treated with porous resorbable calcium carbonate($Biocoral^{\(R)}$), and 15 teeth(test group) were treated with porous resorbable calcium carbonate($Biocoral^{(R)}$) and Platelet Rich Plasma. The change of bone density was assessed by digital subtraction radiography in this study. The change of mineral content by as much as 5%(vol) could be perceived in the subtracted images. The change of mineral content was assessed in the method that two radiographs are put into computer program to be overlapped and the previous image is subtracted by the later one. Both groups were statistically analyzed by Wilcoxon signed Ranks Test and Mann-whitney Test using SPSS program(5% significance level). The results were as follows: 1. In test group, the radiolucency in 3 months after surgry were significantly increased than 1 month after surgery(p<0.05). 2. In test group, there were no significant difference between 1 month after surgery and 6 months after surgery(p>0.05). 3. In test group, the radiopacity in 6 months after surgery were significantly increased than 3 months after surgery(p<0.05). 4. In control group, the radiolucency in 3 months and 6 months after surgery were significantly increased than 1 month after surgery(p<0.05). 5. In control group, the radiopacity in 6 months after surgery were significantly increased than 3 months after surgery(p<0.05). 6. There were no significant difference between test group and control group at 1 month, 3 months after surgery, but radiopacity in test group were significantly increased than control group at 6 months after surgery(p<0.05). In conclusion, Platelet Rich Plasma can enhance bone density.
갱년기 중년 여성의 지속적 운동 습관을 형성하기 위한 디지털 헬스케어 UX 디자인

의학 기술의 발달과 기대 수명의 증가로 중년기 삶의 비중이 커지면서 삶의 질을 향상시키기 위해 중년기 건강 관리에 대한 관심이 높아지고 있다. 통계청이 발표한 2021 년 생명표에 따르면, 남성의 기대수명은 80.6 세, 여성은 86.6 세로 여성의 기대수명이 남성보다 6 년 정도 더 긴 것으로 나타났다. 이는 여성이 남성보다 더 긴 기간 동안 건강 관리 필요성에 직면할 수 있음을 시사한다. 그러나, 만성질병 발생률은 중년기 여성에게서 높은 비율로 측정되어 지속적인 관리가 중년기 여성에게 더 중요할 것으로 예측할 수 있다. 중년기 여성의 질병 발생 원인은 갱년기(질병 또는 노화에 의해 난소기능이 감소하면서 폐경과 관련된 신체 및 심리적 변화를 겪는 시기)에 변화되는 신체×정서적인 노화 증상을 관리하지 못하여 발생한다. 이러한 변화에 대응하기 위해서는 맞춤형 건강 정보, 정서적 지원, 그리고 개인화된 운동 프로그램이 필요하다. 이러한 문제를 해결하기 위해, 본 연구에서는 갱년기를 겪고 있는 중년기 여성이 신체×정서적인 노화 증상을 관리하며 지속적인 운동 습관 형성을 돕기 위한 UX 방안을 제시하고자 하였다. 이를 위해 기존에 출시된 디지털 헬스케어 서비스 내에서 습관 형성을 위해 사용자를 자극하고 있는 습관 형성 요인을 분석하고 분석된 결과를 토대로 중년 여성의 운동 습관을 형성할 수 있는 전략과 개입 방법을 제안하였다. 본 연구를 통해 갱년기를 겪고 있는 중년기 여성 맞춤형 습관 형성 디지털 헬스케어 서비스를 구축하는데 기초 자료로써 도움이 되고자 한다.

The aim of the present study was to review bisphosphonate osteonecrosis of the jaws (BRONJ). Bisphosphonate, pathophysiology, risk factors, staging, clinical manifestation, treatments, and prevention of BRONJ were investigated through a literature search. Bisphosphonates are a group of drugs that treat diseases related to bone resorption such as Paget`s disease, osteoporosis, and osseous metastases. BRONJ is defined as exposure and necrosis of bone in the oral cavity for at least 8 weeks in patients receiving bisphosphonate and with no history of radiotherapy of the jaws. Many articles have reported risk factors associated with BRONJ such as systemic diseases, oral infection, poor oral hygiene, and intraoral trauma. The objectives of BRONJ treatment are to minimize necrosis and relieve symptoms. Many treatments are suggested from conservative treatment to radical intervention, but this remains controversial. BRONJ remains a difficult condition to treat although many studies are being carried out.

클라우드 컴퓨팅은 최근 IT 기술 중 가장 주목받는 분야로, 클라우드 컴퓨팅 자원을 네트워크 기반으로 제공하는 기술이다. 클라우드 환경에서 소프트웨어를 개발하는 경우 가상 환경을 이용해서 작업 비용을 대폭 절감할 수 있는 이점이 있지만, 웹 어플리케이션 취약점을 이용한 웹 기반 공격 등의 보안 문제가 남아있다. 클라우드 컴퓨팅이 인터넷을 통해서 서비스를 제공하기 때문에 웹 보안 향상이 클라우드 컴퓨팅의 중요한 보안 이슈이다. 본 논문에서는 클라우드 시스템의 웹 보안 문제를 해결하기 위해 클라우드 컴퓨팅을 기반으로 다중 웹 방화벽(Web Application Firewall)을 구축하는 방안을 제안하고자 한다.

기존의 네트워크 관문에서 트래픽을 검사하는 장치들은 Application 계층의 데이터를 검사할 수 없어 보안에 한계가 있다. 이를 보완하기 위해 Application 계층까지 패킷을 분석할 수 있는 Deep Packet Inspection (DPI)기술이 개발되어 보안 강화에 사용되고 있다. 하지만 기업에서 DPI 기술을 이용하여 고객의 개인정보를 무단으로 수집 및 이용하면서 DPI 기술에 따른 개인정보 침해가 우려된다, 본 논문에서는 DPI 기술을 통한 사용자 정보 수집 시 개별 사용자의 동의를 받을 수 있는 방안을 제안하며, 이를 통해 DPI 기술에 따른 사용자 개인정보 문제를 해결하고자 한다.
