The objective of this study is to prepare a proposal for desired changes in the laws and regulations system of the Environmental Impact Assessment (EIA) about cultural assets preservation. The related Korean regulatory system and literature for EIA have been surveyed and case studies have been analyzed and actual cases where cultural assets protection were of issue have been studied to deduce the problems of those areas. Based on the result of this study, proposed changes are as follows; 1. "Status of cultural Assets" is to be included as common assessment factor for all categories of object projects in "Table 2: Essential Assessment Factors for Individual Project Category" of "Ordinance for Preparation of EIA Statement, etc." 2. "Status of Underground Cultural Assets and Potential Underground Cultural Assets" is to be inserted as a survey factor in "Table 3:Format of and Instruction for Impact Statement". 3. The clause of "-- the survey should be performed on-site and the investigation report should be submitted." is to be inserted in methods of survey in "Table 3". 4. Ground survey of cultural assets should be performed prior to completion of project planning, that is, from the stage of pre-study for site selection. 5. The application of impact abatement from "Methods and Plants for Impacts Abatement" of "Report for Development of EIA Statement Technologies" should be included, with proper modification of timing, in "Ordinance for Preparation of EIA Statement, etc." 6. The expense liability clause in "Cultural Assets Preservation Act" is to be revised as "a certain ratio of expenses for excavation should be borne by the government." 7. Regulatory device for collecting appropriate opinions should be established. It may include Cultural Assets Preservation Committee's hearing to the project owner's opinion. be established. It may include Cultural Assets Preservation Committee's hearing to the project owner's opinion.

Purpose: The rectus abdominis myocutaneous flap is currently the most commonly used donor site of immediate and delayed breast reconstruction surgery, for its versatility and ease of handling, as well as sufficient blood supply. Despite many advantages of rectus abdominis flap, morbidity of donor site is considered as inevitable shortcoming. The authors recently faced a devastating complication, small bowel obstruction that led to strangulation, after delayed breast reconstruction with free transverses rectus abdominis myocutaneous (TRAM) flap. And we would like to report it, because abdominal pain after TRAM flap is a common symptom and can be overlooked easily. Methods: A 56-year-old female patient who had history of receiving total abdominal hysterectomy 20 years ago underwent delayed breast reconstruction with TRAM flap transfer. She complained abdominal discomfort and pain from third postoperative day, postoperative small bowel obstruction that arose from strangulated bowel and prompt emergency operation was done. Results: After resection of the strangulated bowel and reanastomosis, quickly her symptoms were relieved, and there were no further problems during her hospital stay. 7 days after her emergency operation she was discharged. Conclusion: In patients with previous abdominal surgical history, prolonged ileus can lead to bowel strangulation, so surgeons should always consider the possibility, and must be aware of abdominal symptoms in patients who receive free TRAM flap operations.

Atrophic alveolar ridge of maxillary anterior area is commonly observed after the extraction of teeth in patients with severely compromised periodontal disease, causing difficulties with implant placement. Successful esthetics and functional implant rehabilitation rely on sufficient bone volume, adequate bone contours, and ideal implant positioning and angulation. The present case report categorized the ridge augmentation techniques using guided bone regeneration (GBR) on the maxillary anterior site by Seibert classification. Case I patient presented for implant placement in the position of tooth #11. The alveolar ridge was considered a Seibert classification I ridge defect. Simultaneous implant placement and GBR were performed. Eight months after implantation, clinical and radiological examinations were performed. Case III patient presented with discomfort due to mobility of the upper maxillary anterior site. Due to severe destruction of alveolar bone, teeth #11 and #12 were extracted. After three months, the alveolar ridge was considered a Seibert classification III ridge defect. A GBR procedure was performed; implantation was performed 6 months later. Approximately 1-year after implantation, clinical and radiological examinations were performed. During the whole treatment period, healing was uneventful without membrane exposure, severe swelling, or infection in all cases. Radiographic and clinical examinations revealed that atrophic hard tissues and buccal bone contour were restored to the acceptable levels for implant placement and esthetic restoration. In conclusion, severely resorbed alveolar ridge of the maxillary anterior area can be reconstructed with ridge augmentation using the GBR procedure so that dental implants could be successfully placed.

Purpose: The purpose of this study is to identify the effects of suicide reports by mass media and social support on suicide ideation for college students. Methods: Participants are 350 undergraduate students in one university. This study uses three questionnaires: Perception and Attitude toward Suicide Reports, Social Support, and Suicidal Ideation. The SPSS/WIN 12.0 program is used to analyze the data. In particular, the participants' biographical data are analyzed into frequency and percentage. The degrees of suicide reports, social support, and suicide ideation are calculated into Mean and SD. Moreover, the suicide ideation by suicide report and social support are analyzed by the two-way analysis of variance (ANOVA). Results: This study reveals that college students have an average of 30 minutes to one hour news time a day (38.9%) and have at least one suicide report in a month (30.3%). 79.7% participants believe that the suicide report of mass media results in the cause of the copycat suicide. In terms of suicide report and suicide ideation, the types of mass media (F (4,340)=2.41, p<.05) and suicidal urge (F (1,340)=31.23, p<.01), respectively, have significant influences on suicide ideation. On the other hand, the social support and suicide ideation, whether college students have their mentors (F (1,328)=13.26, p<.001) and/or careres (F (1,328)=26.84, p<.001) have significant influences on suicide ideation. Conclusion: College students have higher suicide ideation at news by internet site rather than by radio, TV, and so on. Moreover, college students who have a suicide feeling in the last one year, have more suicide ideation than who have not. On the other hand, college students who have a mentor and carer tend to have less suicide ideation.

Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

Alveolar Soft Part Sarcoma(ASPS) is a rare entity that invariably ends in death from the disseminated disease. Although the most common site of metastasis is the lung, the central nervous system is also the third common site. Its histogenesis remains to be unknown and the gold standard treatment is radically surgical removal of the mass. However, adjuvant chemotherapy and radiotherapy are known to be less effective. The authors present a 24-year-old man who was admitted with headache and neck discomfort. Magnetic resonance( MR) imaging scans demonstrated multiple masses in the left frontal lobe, parietal lobe, and right cerebellum. The patient underwent surgery to remove multiple masses in the staged fashion. The postoperative course was uneventful, but the patient committed suicide 5 months later. The authors reviewed the pertinent literature and discussed this clinical entity with references.

Ergonomic intervention techniques were adopted to assess and control potential risk factors of work-related musculoskeletal disorders(WMSDs) in the automated light assembly manufacturing system. Ten different kinds of assembly workstations implemented with a conveyor system and twelve female workers were observed and evaluated with careful video film analysis. Several close examinations using sets of checklists established by qualified safety and health organizations, such as NIOSH, OSHA, and ANSI, were conducted and every workers and staffs in the site participated in the self-report questionnaires and off-line interviews. Typical risk factors and symptoms of the upper extremity musculoskeletal disorders were found and categorized into specific parts of body. To reduce risk factors of WMSDs and improve system productivity new revised workstation standards, physical dimensions, were suggested accordant with anthropometric characteristics of workers and a heuristic decision strategy of rotating shift work schedules according to work contents has proposed to mitigate cumulative physical stress. Finally, ergonomic programs of entire company to prevent WMSDs were structured.

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are usually classified, depending on their extent and radiographic appearances, into three main groups. Periapical cemental dysplasia predominantly involves the periapical region of the anterior mandible. Florid cemento-osseous dysplasia presents with multifocal lesions in the tooth bearing or edentulous areas of the maxilla and mandible, often occurring bilaterally with symmetric involvement. Focal cemento-osseous dysplasia exhibits a single site of involvement in any tooth bearing or edentulous area of the mandible or maxilla, with the posterior mandible representing the most common site. We report the clinical, radiographic and histological findings of 3 types of cemento-osseous dysplasia with a review of literatures.

A 78-year-old man underwent laparoscopy-assisted total gastrectomy for gastric cancer (pT3N0M0). Multiple port sites were used, including a 10 mm port for a videoscope at the umbilical point and three other working ports. During the six-month follow-up evaluation, a 2 cm enhancing mass confined to the muscle layer was found 12 mm from the right lower quadrant port site, suggesting a metastatic or desmoid tumor. Follow-up computed tomography imaging two months later showed that the mass had increased in size to 3.5 cm. We confirmed that there was no intra-abdominal metastasis by diagnostic laparoscopy and then performed a wide resection of the recurrent mass. The histologic findings revealed poorly differentiated adenocarcinoma, suggesting a metastatic mass from the stomach cancer. The postoperative course was uneventful, and the patient completed adjuvant chemotherapy with TS-1 (tegafur, gimeracil, and oteracil potassium). There was no evidence of tumor recurrence during the 50-month follow-up period.
