Foramen of Morgagni hernia is the least common type of all congenital diaphragmatic hernias. These foraminal hernias result from a congenital defect in the development or attachment of the diaphragm to the sternum and costal arch. They occur most commonly on the right side, possibly because of pericardial reinforcement of the left. In our case, occurred on the right side and the contents of the hernial sac were omental fat and a part of transverse colon. We performed transthoracic approach for reduction and repair of foraminal hernia with ligation and interrupted mattress sutures of the margin of the defected diaphragm to the posterior part of the sternum and costal cartilage. The postoperative course was uneventful except posttraumatic delirium and discharged at 21st postoperative day.

Mussels are stubborn organism attached to solid substrate by byssus threads and caused operational problems in utility of power generating stations. Sole and combined usage of ultrasonic (28 kHz- and 42 kHz- frequencies) and hydrogen peroxide ($H_2O_2$) has studied for control of blue mussel larvae and adult stage in seawater condition. A theoretical wo rking model using disinfection (Chick and Watson type) approaches is presented based on helpful results of experiments. This study also demonstrate that the combined treatment (ultra-sonication with $H_2O_2$) is overall highly efficient than individual treatment would, but on the basis of exposure time, the ultra-sonication was the most efficient among them. Therefore the development of sole and combined technique might be effective practical mitigation strategy against mussel attachment for water handling facilities.

This research was intended to design an experimental girdle with thermal insulation function for adult women in their 20s. The design of the experimental girdle was based on the pattern of commercially available girdle. The final pattern of the experimental girdle was established according to the drawing equations determined based on the result of appearance evaluation. The equations were (waist circumference${\times}0.88$)/2 for waist circumference, (hip circumference${\times}0.77$)/2 for hip circumference, and (thigh circumference${\times}0.85$) for thigh circumference. In order to develop a heating device, the most effective fabric heater was adopted based on the experiments about the number of caron fibers, heater size and attachment site. Three heaters-one with a size of $14.5{\times}9.5$ cm, and the other two with the size of $8.0{\times}15.0$ cm-were attached to the areas corresponding to the lower abdomen and the hip, 5 cm below the waist. A heater was developed by connecting these heaters to a controller, 2 batteries (7.4 V 2000 mAh lithium polymer batteries) and a switch (for mode conversion between high/medium/low temperatures). The heater was integrated into the inside of the girdle, so that attachment and detachment were possible without the change of appearance. The tentative configuration plan was proposed for the development of a functional smart girdle with an excellent thermal insulation effect.

In order to evaluate the effects of the early exposure of e-PTFE membrane on the periodontal regeneration, 21 cases of 21 patients diagnosed as the chronic adult periodontitis were evaluated. All were class II furcation involvement cases. The control group was composed of 7 cases treated only by the flap operation. 14 cases were treated by the e-PTFE membrane as the experimental group, the membranes of 7 cases were exposed more than 1mm during healing period, which were named as the experimental group I, and the others, experimental group II. Clinical parameters such as probing pocket depth, clinical attachment level, bone probing depth, and gingival recession were recorded before the treatment and 6 months after the treatment. The results were as follows. 1. Significant probing depth reductions were observed for all groups(p<0.05), but no group shows significantly greater reductions than another. 2. Significant clinical attachment gains were observed for the experimental group II(p<0.05), no significant gains were observed in the other groups. 3. Significant bone probing depth reductions were observed for the experimental group II(p<0.05), no significant reductions were observed in the other groups. 4. All but the experimental group II exhibited a significant increase in gingival recession(p<0.05). The result suggested that is case of the e-PTFE membrane is exposed, the result is similar to that of flap operation without membrane. Therefore selecting the proper treatment case, intricate surgical procedure and infection control are essential for minimizing the chance of membrane exposure and finally for the good treatment results.

The aim of the present investigation was to see the effect of combined use of PDGF BB and IGF -1 on the guided tissue regeneration(GTR) using barrier membrane in the treatment of human furcation involvement. Twelve patients with initially diagnosed as having moderate to advanced adult periodontitis with mandibular class II buccal furcation defects have been wer selected. Initial scaling and root planing has been performed and baseline data consisting of probing depths and attachment levels have been recorded prior to surgical procedures. The GTR procedures using either barrier membrane(control : ePTFE) alone or together with the application of PDGF - BB and IGF -l(experimental : ePTFE+PDGF/IGF) have been done under the routine guidelines. During the surgery, the distance from CEJ either to the bottom of the bone defects(CEJ - BD) or to the bone crest(CEJ-BC) were measured. Horizontal distance to the deepest area in the furcal defects were measured from the reference line connection the most prominent bony walls of the two buccal roots. 6 months following the GTR therapy, all the measurements were made repeatedly. The probing attachment gain of the experimental and the control grous were 2.14mm and l.07mm, respectively with no statically significnant difference. Amont of vertical bone fill in the experimental and the control groups were 2.43mm and 2.29mm, rexpectively. Amonut of horizontal bone fill were 2.86mm in the experimental group and 2.17mm in the control group, respectively. However, there were no significant differences in the amount of bone fill(both vertical and horizontal)between the two groups.

The purpose of the present investigation was to compare the effectiveness of porous hydroxyapatite (PHA) and coralline based porous calcium carbonate(PCC) as implant materials in human periodontal osseous defects. 10 adult patients having periodontitis and 2 similar angular osseous defects ${\ge}$5mm as verified by radiographic analysis and clinical probing depth ${\ge}$4mm were selected. The measurements were recorded just before surgery and after 6 month. Clinical parameters used in this study included gingival recession, pocket depth, probing attachment level, Sulcus Bleeding Index, Plaque Index, tooth mobility and bone defect depth measurements. After initial therapy, patients were treated with mucoperiosteal flap surgery. The contralateral bony defects in each patient randomly assigned to either bone graft material, one with PHA(Interpore 200) and the other with coralline based calcium carbonate(Biocoral). After 6 month both groups showed statistically significant reduction of pocket depth, Sulcus Bleeding Index, Plaque Index and significant improvement in probing attachment level. No statistically significant differences were found between the groups. There were 3.0mm or 68% of bone repair with PHA and 3.1mm, 61% with PCC. These values were likewise not significantly different. The data and clinical impression strongly suggest that both PHA and PCC are alloplastic implants with clinically apparent acceptance by the soft and hard tissue and that they can be used as bone graft materials successfully.

The primary aim of this systematic review was to assess the evidence on periodontal disease progression after treatment in patients receiving supportive periodontal therapy (SPT) and to identify predictors of clinical attachment level (CAL) loss. A protocol was developed to answer the following focused question: In adult patients treated for periodontitis, what is the disease progression in terms of CAL loss after surgical or non-surgical treatment? Randomized controlled clinical trials, prospective cohort studies, and longitudinal observational human studies with a minimum of 5 years of follow-up after surgical or non-surgical treatment that reported CAL and probing depth changes were selected. Seventeen publications reporting data from 14 investigations were included. Data from 964 patients with a follow-up range of 5-15 years was evaluated. When the CAL at the latest follow-up was compared to the CAL after active periodontal therapy, 10 of the included studies reported an overall mean CAL loss of ${\leq}0.5mm$, 3 studies reported a mean CAL loss of 0.5-1 mm, and 4 studies reported a mean CAL loss of >1 mm. Based on 7 publications, the percentage of sites showing a CAL loss of ${\geq}2mm$ varied from 3% to 20%, and a high percentage of sites with CAL loss was associated with poor oral hygiene, smoking, and poor compliance with SPT. The outcomes after periodontal therapy remained stable over time. Disease progression occurred in a reduced number of sites and patients, mostly associated with poor oral hygiene, poor compliance with SPT, and smoking.

자녀양육에 수반되는 시간적 금전적 비용부담이 기혼여성의 노동시장 진입과 경력단절에 가장 큰 영향을 미치는 요인으로 지적한 선행 연구들은 이에 대한 정책적 지원을 강조하였다. 사회복지정책이 발달한 국가에서 세대간 동거(co-residence)는 고령층의 의료 및 부양과 관련된 공적 비용을 사적 비용으로 전환하고, 공식적인 부양을 비공식적인 것으로 대체하는 동시에 기혼여성의 노동공급을 증가시킨다는 관점에서 정책 설정에서 주요한 개선방안으로 인식되고 있다. 본 연구는 "한국노동패널" 2차년도(1999) 자료를 이용하여 부모세대와의 동거상태, 부모 및 기혼여성 본인의 건강상태가 기혼여성의 노동공급에 미치는 영향을 살펴본다. Tobit모형의 추정 결과, 동거 여부, 여성노인과의 동거, 노동시장 근로를 하지 않는 여성노인과의 동거는 동거하는 노인의 건강상태에 관계 없이 기혼여성의 노동공급량에 정(+)의 효과를 미치는 것으로 나타났다. 세대간 동거는 세대간 사적 자원이전 (intergenerational private transfer of resources)을 통하여 기혼여성의 노동공급에 긍정적인 영향올 미치며, 이는 세대간 사적 자원이전이 여성노인을 중심으로 시간자원의 이전이라는 형태를 취하고 있음을 의미한다.
