The purpose of this study is to develop and evaluate a school-based alcohol and delinquency prevention program. The program emphasizes the acquisition of skills to effectively deal with peer pressure specific to alcohol use and delinquency as well as to build more healthy relationships with both parents and friends. The program was operated by social workers in a middle school in Seoul for almost 2 months. The program produced positive results. That is, students' drinking frequencies, the level of positive alcohol expectancies, and the level of delinquency have been lowered. Finally, this study suggests that the length of the program be extended and the program be replicated by future social work practitioners and researchers in order to make the program more effective.

The treated ballast water from previous treatment contains microorganisms and pathogenic organisms in an filtration treatment system. The advantage of this process can be filtrated to minimize the demage to screen clogging of drum filter with sweeping the solids off rotating the surface of the filter. Another advantage is to drop off the solids with controlling revolution of drum screen in pretreatment filtration process. Also the fact that it is easy to attach and detach a several type of screen for getting the expected water quality is another advantage, too. Filter rotation speed at 20rpmis 40.5cmHg and 40rpm is 36.6cmHg. Filter out impurities from ballast water over 60rpm is 35cmHg. Filtration system removal aquatic organism over $80{\mu}m$ in ballast water. This study shows that the filtration treatment system has a potential for the removal of ballast water.

A 49-year-old male was found unconscious at his accommodation and visited the emergency room. He was on antipsychotic and antidepressant drugs (vortioxetine hydrobromide, mirtazapine, sertraline hydrochloride, quetiapine, and alprazolam) for schizophrenia and major depression. At the time of discovery there were signs of overdose of the drugs around the patient. A physical examination revealed, pain, pallor, and edema in the left buttocks and lateral thigh. Active ankle movements below the left ankle were not possible and sensations in the tibia and peroneal nerves were lost. The pressure in the buttock compartment was measured at 42 mmHg. Magnetic resonance imaging revealed edema and high intensity signals in the left hip muscles and surrounding soft tissue. An emergency fasciotomy was performed and partial restoration of the lower extremity sensation and muscle strength were achieved after 24 hours.

When patients suffer from finger injuries, their finger joints can become stiff and inflexible due to decreased ability to exercise the finger tendons. This can lead to a loss of strength and difficulty using their hands. To address this, it is important to provide patients with consistent rehabilitation treatment that can help restore finger flexibility and strength simultaneously. In this study, we propose wearable gloves that use FSRs (force sensitive resistors) for finger strength training. The glove is designed to be adjustable using rubber bands and a custom PCB is designed for signal acquisition. For the evaluation of finger strength training, the result was analyzed in four cases. We suggest a vector that represents the center of five finger forces, and the result shows that the vector can indicate the level of force balance.

최근 도시화 및 불투수면의 증가와 지하수의 과다한 사용으로 직접유출이 증가하고, 침투량이 감소하며, 하천의 건천화가 발생하고 있다. 이에 환경부에서는 이러한 물순환의 왜곡을 막기위해 물환경보전법상의 물순환율을 정의하고 물순환 관리목표를 설정하였다. 하지만 지역 별 물순환 특성을 반영한 관리계획이 부족하고, 현재 제한된 재원의 효율적 활용을 위해서는 물순환 관리지역에 대한 우선순위 결정도 필요하다. 본 연구에서는 PSR framework를 통해 유역 물순환 평가방법론을 만들고 이를 활용한 지역별 관리계획 및 우선순위를 결정하고자하였다. PSR framework는 지속가능성을 위해 OECD가 개발한 개념 모형이며, Pressure, State, Response 세 가지 요소로 구분해 평가하게된다. PSR framework의 기본 개념은 인간의 활동들이 환경에 압력 (P)를 주고, 이로 인해 자연의 질과 영향 (S)을 미치며, 이에대한 회복을 위해 인식과 행동을 통해 정책과 제도 등을 통해 반응 (R)한다는 것이다. 유역 물순환을 4가지 그룹 (기후, 수문학적, 사회경제학적, 환경적)으로 구분하고 각 그룹 별 평가요소에 대하여 도출하였다. 기후그룹은 강우, 수문학적 그룹은 증발산, 토지이용, 유출특성을, 사회경제학적 그룹은 재정, 사회구조, 기반시설, 정책을, 환경적 그룹은 수질, 수생태계를 선정하였다. 이후 각 요소 별 평가를 위해 다양한 지표를 고려하여 선정하였으며, 각 지표를 PSR framework에 맞춰 재분류하였다. 각 지표를 하나의 점수로 통합하기 위해 지표 별 가중치를 산정하였으며, 이때 연구자의 주관이 반영되지않는 엔트로피 기법을 이용하여 산정하였다. 구한 식을 통해 우리나라 소유역구분을 기준으로 모든 지표를 계산하였으며, 각 지표에 가중치를 적용해 유역 종합점수를 산정하고 유역 별 취약지역 및 취약요소를 평가하였다.

급격한 도시화와 이로인한 불투수면의 증가는 유역의 물순환을 왜곡시키고 있다. 직접유출의 증가와 침투량 감소로 이어지며 이는 지하수 함유량의 감소와 하천건천화를 유발한다. 환경부는 더 이상의 물순환 왜곡을 막기위해 물환경보전법상의 물순환율을 정의하고 물순환 관리목표를 설정하였으며, 제3차 강우유출 비점오염원관리 종합대책에서 물순환 사업 추진을 위한 소권역 별 우선순위산정을 과제로써 제시하고 있다. 대표적인 물순환 사업은 저영향개발기법 설치이다. 저영향 개발기법은 토지 및 공간을 이용해야하기 때문에 설치비용이 높고 위치선정에 제약이 많으며 유지관리도 어렵다. 이에 물순환 사업에는 단순 불투수면 뿐만아니라 사회, 경제적 요소까지 고려하여야한다. 본 연구에서는 물순환 우선순위를 산정하기위해 불투수면뿐만 아니라 사회, 경제적 요소까지 고려한 종합적인 우선순위를 산정하였다. 유역 물순환 평가를 위해 PSR framework을 이용하였다. PSR framework는 OECD가 개발한 지속가능성 평가 개념이며, Pressure, State, Response 세 가지 요소로 구분해 평가하게된다. PSR framework의 기본 개념은 인간의 활동들이 환경에 압력 (P)를 주고, 이로 인해 자연의 질과 영향 (S)을 미치며, 이에대한 회복을 위해 인식과 행동을 통해 정책과 제도 등을 통해 반응 (R)한다는 것이다. 본 연구에서는 PSR framework의 평가요소 Pressure는 불투수면 및 강우, State는 물순환, 하수관거, 수질, 수생태계, Response는 협력, 인식, 재정, 토지로 구분하여 평가하였다. 최종적으로 불투수면적 감축 대상 소권역('30년 무대책 불투수면적률 25% 이상)소권역에 대하여 최종우선순위를 산정하였다.

식민지하 동남아 천년왕국 운동에 대한 오늘날의 해석들은 그 주체인 농민들을 식민주의를 개념화하고 저항하는 동기와 조건 그리고 상징을 제공하는 토착 지식의 전수자로 간주한다. 종말론과 저항에 대한 관심의 대부분은 농민연구나 지역연구 학자들로부터 유래하며, 이들은 봉기에 대한 과거의 묘사들이 토착의 정신세계를 간과했거나 국가이념을 저항세력들의 결집원리로 과대 포장한 것에 주의를 기울인다. 천년왕국 봉기에 관한 글들에서 제공하는 해석들은 동남아 신념 체계에 관한 독립적인 관점을 제공할 뿐만 아니라, 인식론적 측면에서 식민지국가들을 이와 같은 전통에서 단절시키고 있다. 영국 식민지하에서 최대의 농민반란인 서야쌍 봉기(1930-1932)는 오늘날 이와 같은 천년왕국 운동의 정수를 보여주는 사례로 간주된다. 학자들은 수천 명의 농민들로 하여금 버마인의 권위를 되찾고, 불교를 회복시키며, 식민통치로 인해 낳은 사회-경제적 부조리를 일소시킬 그들의 왕으로 믿게 만든 한 농부의 흥미로운 이야기를 묘사하고 있다. 일련의 반란이 미신에 의해 추동되었다고 간주한 식민지 관찰자들과는 달리 이후의 역사가들은 그 반란이 불교를 재건하고 태평성대로 인도할 미래부처인 미륵불의 현신에 대한 믿음의 표현이라고 해석했다. 이러한 학자들에게 서야쌍 봉기는 어떻게 동남아 사람들의 감수성이 식민지의 사회-경제적 압력 속에서도 지속되었으며, 상좌불교의 예언이 토착의 문화적 토양에 얼마나 깊이 내재해 있는지를 말해주는 사례였다. 경험적 관점에서 본 글은 서야쌍 봉기의 근원을 재해석함으로써 천년왕국 봉기에 관한 글들이 대부분 식민지적 문서화 작업과 종교를 과장되고 세속화된 화술로 믿게 하려고 지역연구자들의 산물임을 밝히고 있다. 개념적 관점에서 본고는 버마에서 일어난 천년왕국 운동의 역사적 구성에 대한 식민주의의 역할을 보다 면밀히 관찰하였다. 또한 식민지법, 학문, 그리고 식민지하 버마 농촌에서 발생한 종교적 저항에 대한 우리들의 이해를 상호 연결하는 인식론적 관계를 탐구했다. 그리하여 본고는 천년왕국 해석이 이 시기에 공존했던 다른 유형의 불교정치적 형태를 어떻게 왜곡했는가를 밝히고 있다.

Prosthetic valve thrombosis(PVT) may be a life-threatening complication requiring prompt intervention. This is a case report of thrombolytic therapy for thrombosis of prosthetic mitral valve. A 47 year-old male admitted to the emergency room for abrupt onset of dyspnea. He had undergone mitral valve replacement(On-Ⅹ valve, 29mm) for mitral stenosis 8 months ago. The patient's international normalized ratio(INR) on admission was 1.09. The mechanical clicks were muffled and rales were heard in both lung fields. A transesophageal echocardiography(TEE) revealed prosthetic valve thrombosis with increased transvalvular pressure gradient(34 mmHg). The patient's condition needed to intubation for mechanical ventilation due to hemodynamic compromise, however his wife and relatives refused the surgical intervention due to financial problems. The patient was transferred to the cardiac care unit and we decided to perform thrombolytic therapy. A bolus of 1,500,000 IU of urokinase was given, followed by a drip of 1,500,000 IU for 1 hour. The patient did not improved hemodynamically; therefore, we gave 100 mg of tissue plasminogen activator(t-PA) for over 2 hours. During that time mechanical clicks were audible and hemodynamics of the patient improved progressively. A TEE showed disappearance of thrombus and decreased pressure gradient(1.7 mmHg) after 6 hours of thrombolytic therapy. The patient was recovered without any neurologic sequale and was discharged with administration of warfarin.

Polly-pigs technique was developed to remove internal rusts and scales from service pipes in the building by using Polly-pigs that were used as various applications in conventional plant pipelines. Results of cleaning experiments on 15mm GSP(Galvanic Steel Pipe) showed that hydraulic cross sectional area was more increased from 3.5% to 15.4% for straight part or elbow parts of several test pieces. Results of optical analysis also showed that rust and scale removed mostly by KDP series(only consisted of Polyurethane) were outside red colored scale ($Fe_2O_3{\cdot}H_2O$), and there was a limitation to the removal of black colored scale($Fe_2O{\cdot}nH_2O$) that was below red colored scale. But it was evaluated that KDPS series coated fine sand with KDP series could remove not only red colored scale but also black colored scale and more increase hydraulic cross sectional areas of 15mm GSP old service pipes from 13.0% to 17.9%. After KDPS series cleaning, hydraulic cross sectional areas of them were recovered from 95.9% to 99.5%. Turning force of Polly-pigs was largely improved by the effect of Helical guide vane(Cleaning v/v) and Rotating wing(Pigs), and the number of pig rotating also more increased sixteen times compared with conventional cleaning system without Helical guide vane and Rotating wing. After KDPC series cleaning of 100mm GSP old service pipes that hydraulic cross sectional areas were 90%, hydraulic cross sectional areas were almost recovered perfectly like new service pipes. Additionally pressure necessary to run Polly-pigs m 100mm GSP was lower and cleaning efficiency also was higher than 15mm GSP cleaning. Therefore it was thought that as the diameter of pipe was more increased, pressure necessary to clean service pipes was more decreased and cleaning efficiency was more increased in Polly-pigs cleaning.

Globalization has conflicting effects on pharmaceutical policies. A change into a 'populist competitive nation' due to globalization strengthens policies to reduce drug manufacturing costs while the WTO's TRIPS Agreement that is affected by multinational pharmaceutical companies increases drug manufacturing costs by bolstering the patent rights on new drugs. Currently, the independency of populist nations' policies to reduce drug manufacturing cost is being compromised because multinational organizations(such as the European Union) which represents the interests of the multinational pharmaceutical companies put restrictions on the pharmaceutical policies of populist nations for purposes of promoting the industrial goals of the multinational companies. Korea is no exception. Up until the late 1990s, the main feature of the pharmaceutical policies in Korea was keeping the drug price at the cost level based on a growth-driven ideology, and this was Korea's unique policy tools as a developing nation. However, the increase in the power of multinational pharmaceutical companies currently infringes on the independency of Korea's pharmaceutical policies. Expensive imported drugs were originally covered by the national health insurance plan, but starting from 1999 such drugs began to be covered by the plan. After separation of medical and pharmaceutical services, the use of expensive drugs was increased, and the Korean government planned to introduce the reference price policy in order to contain the cost of the national health insurance plan. However, due to pressures from the U.S. government as well as multinational pharmaceutical companies, implementation of the policy has been postponed. In addition, due to a pressure from the U.S. government, a working group was created which would affect the health care policy of the Korean government. Discussions so far on globalization was about whether the change into populist competitive nations due to globalization resulted in the reduction of welfare spending. However, this study shows not only the reduction of health care cost through policies to reduce drug manufacturing costs but increase in welfare spending by raising the strengths of multinational pharmaceutical companies that are for-profit providers of welfare service. While focusing on the contradictory effects of globalization on pharmaceutical policies of a nation, this study looked at how these conflicting effects end up promoting the interests of multinational pharmaceutical companies by examining the Korean case.
