바이오디젤은 식물성기름등으로부터 제조시 메탄올과의 반응으로부터 제조되므로 바이오디젤의 잔존 메탄올은 화재폭발위험성을 높일 수 있다. 바이오디젤에 존재하는 메탄올의 위험도를 측정하기 위하여 바이오디젤에 메탄올을 일정 비율로 첨가하여 인화점과 동점도를 측정하였다. 바이오디젤의 인화점은 메탄올의 증가에 따라 현저히 감소하였으며 동점도도 감소하는 것으로 나타났다. 실험결과 바이오디젤 연료에 반응물 메탄올이 잔존하거나 또는 연료의 점성을 낮추기 위하여 첨가되는 메탄올은 바이오디젤의 인화점을 낮추어 화재폭발 위험성이 높은 것으로 나타났다.

While a number of Korean companies have undergone ceaseless restructuring to survive today's rapidly changing global economy, the brick and mortar industry has been exerting their efforts to enhance the productivity through the development of new products, quality improvement, cost reduction measures. At present, various risk-evaluation measures have been taken in the fields at the discretion of an enterpriser, though, the effective methods enabling quantitative analysis are insufficient. Accordingly, this study is intended to contribute to the synthetic safety manage -ment in the factory fields and to suggest the quantitative -risk-analysis system by introducing such safety-estimation steps as assortment of processes, pre-assessment of risk factors, decision of risks, counter measures against studied risks, establishment of remedies.

Cancer chemoprevention Chemoprevention with strategies using food phytochemicals is currently regarded ascompose one of the noticeable most visible and promising scientific fields for cancer control. A large body of data from both epidemiologic and rodent studies has demonstrated that the ingestion of various vegetables and fruits is occasionally beneficial for cancer risk reduction of cancer risks in humans.(omitted)

Acceptable risk problem are decision problems they requires a choice among different estimations of technological risks. The alternative option includes a threat to life among its consequences. However, the definition used to ignore the public's perceived risk which should be identified as acceptable risk. The study examine the role of perception of risk as acceptable risk between different situations of estimated consequence and probability of risk. The cost benefit principle for the reduction of risk applied to find the possible solutions with in decision making process.

Heterocyclic aromatic amines (HCAs) are established genotoxic human cancer risks, that display their activity also in a number of animal models and in vitro. They are formed during the trying or broiling of creatinine-containing foods, mainly fish or meat. We established that mixing soy protein with ground meat blocks the formation of HCAs. we also observed that coating the surface of meat with polyphenols green or from black tea gives a dose - related reduction of the formation of HCAs.(omitted)

Purpose: The majority of nasal bone fractures have been managed by routine procedure of closed reduction, intranasal packing or intranasal Kirschner wire (K-wire) splinting. But it leaves rooms for many complaints from patients such as pain, rhinorrhea and nasal obstructioon. Another option is, of course, no packing at all. The study was initiated to assess the necessity to pack or splint the nasal bone after routine closed reduction. Methods: We analysed the medical records of 35 patients with nasal bone fracture who were operated by closed reduction in the last 2 years. We evaluated the postoperative CT scan scores and external deviation criterias 1 month after the operation. Results: The postoperative deviation criteria and postoperative CT scan score were favorable and there were no serious complications using this technique. Conclusion: The present study demonstrates that the use of packing or splinting need not be routine in the majority of cases. The risks and discomforts associated with these procedures can often be avoided.

There are a lot of trace gas of gaseous pollutants produced from farm animals. CO2 and CH4 are gases produced directly by the animal. NH3, N2O are produced from animal waste. Most of the effects of these gaseous pollutants on the farm animals have not been investigated in detail. CO2 emission from animal is very little. CH4 release from ruminant is also considered to be a significant factor in potential global warming. Nitrous oxide (N2O) emissions could be avoided by using organic or mineral fertilizer only as much as is needed by plant growing. This paper gives an overview about problems and solving strategies for possibilities for reduction of gaseous pollutants. The way to reduce the gaseous pollution risks from livestock systems are discussed.

Cancer is one of the leading causes of death in Thailand as well as other countries. Evidences from studies in Asia show that alcohol consumption has been linked to an increased risk for various types of cancer. In the qualitative participatory action research presented here, the possibilities of a volunteer women's movement to reduce harmful alcohol consumption by facilitating the creation of emancipatory knowledge in the Thai-Isaan community was explored. During in-depth interviews with 10 female volunteer participants, the following themes emerged: merit making, developing a sense of personal empowerment, and the experience of participating in an action plan that utilized various strategies. The project activities empowered participants to create and share knowledge which was then applied toward action for change. Adoption of this type of program by local health care providers to reduce health problems and risks related to alcohol misuse in similar contexts and cultures is recommended.

This case report describes our treatment of a persistent periantral abscess in a 35-year-old woman. The abscess developed following a zygoma-reduction surgery, during which a preexisting fungal ball had not been addressed. Our comprehensive treatment approach included functional endoscopic sinus surgery, fungal ball removal, abscess drainage, and debridement. Two weeks postoperatively, the patient's symptoms had resolved. A 6-month postoperative follow-up revealed no signs of recurrence or complications, and the patient reported satisfactory functional and aesthetic results. This case underscores the importance of thorough preoperative evaluations and raises awareness about the potential risks of untreated asymptomatic pathologies, which can potentially progress and lead to further complications.

최근 유전학에서 주요 목표중 하나는 복합질환에 영향을 미치는 유전적 요인을 찾아내는 것이다. 유전자좌간의 상호작용이 있을 때에는 단일 유전자좌 분석으로는 이러한 목표를 달성하기 어려우므로, 유전자-유전자간 상호작용이나 유전자-환경인자간 상호작용분석을 고려할 필요가 있다. 자주 사용되는 MDR(multifactor dimensionality reduction)방법은 데이터를 고위험군과 저위험군으로 각각 병합하여 사용하므로 특정 유전자형에서 차이가 나는 경우에는 이를 찾아내기 어렵다. 본 연구에서는 이러한 점을 보완하도록 유전자형 조합에서의 대조군과 질환군의 상대위험도를 이용하여 유전자-유전자간 상호작용을 탐색하는 방법을 제안하였다. MDR 공개데이터와 8가지 유전모형으로부터 생성한 모의자료의 분석을 통해 방법의 유용성을 확인하였다.
