Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

N/A This study aims to investigate the characteristic of swine wastewater treatment by liquefied fertilizer tank and outlne of optirnuin manuring of liquefied fertilizer. The results of this study were summarized as follows: The concentrations of BOD5 in raw manure are 15,320 ㎎/L at slurry/scraper type 19,950 ㎎/L at slurry type and 9,010 ㎎/L at scraper type of piggery. The removal rates of the organic substance were 45.3% at slurry/scraper type 54.8% at slurry type and 61.3% at scraper type of piggery. The concentration of NH₃-N was relatively higher at slurry/scrapei type and at slurry type of piggery which contained more feces than at scraper type of piggery. Frorn the beginning of storage to 100 days the concentration of N and P was changed unsteadily, but after 130 days N and P was shown relatively stable concentration. As standard of N concentration after 6 months storage. the required atea of grassy place per a head of animal is 295 ㎡/head at slurry/scraper type 318㎡/ihead at slurry type and 294 ㎡/head at scraper type of piggery.

[논문]억지말뚝을 이용한 자립식 흙막이 공법의 해석기법 개발
권정근,임종철,김창영 釜山大學校生産技術硏究所 2008 生産技術硏究所論文集 Vol.67 No.-
억지말뚝을 이용한 자립식 흙막이 공법은 많은 실험과 현장적용을 통해 경제적이며 효율적인 공법으로 입증되었다(김,2006). 그러나 지반공학적인 이론적 확립이 되어 있지 않았다. 이에 이론적인 해석기법의 개발을 위해 실제 시공여건을 반영한 단계굴착을 통한 실내모형실험이 수행되었다. 본 연구에서는 단계굴착에 따른 흙막이 벽체 및 억지말뚝의 거동과,단계굴착에 따른 흙막이 벽체와 억지말뚝에 작용하는 토압과 응력을 분석하였다. 그 결과를 바탕으로 지반의 파괴 메카니즘을 제안하였으며 연결부,엄지말뚝,억지말뚝의 해석기법을 개발하였다.
