One 19-year-old male was admitted to P.N.U. Hospital on March 19, 1966, because of severe recurrent, colicky abdominal pain, chillness, nausea, vomitting, headache, sweating, extreme weakness and dizziness for two days'duration, and brownish dark urine on one occation after 24 hours of administration of the Secobarbital 400mg (4 cap.). Another 21-year-old male was admitted to this hospital, on March 21,. 1966, because of unconsciousness after ingestion of the secobarbital 1, 700mg (17 cap.).. After recovery from this state on the second days of admission, he has complained the . chillness, diffuse, colicky abdominal pain, myalgia, and headache, and also discharged dark urine in the evening. The diagnosis of the acute hemolytic anemia was established by means of the abovesymtoms, physical examinations and laboratory findings of which, the peripheral blood showed hemoglobinemia in the serum, increased bilirubin titer, mostly indirect, and spherocytosis; hemoglobin in the urine. After initial. response to therapy with blood transfusion (5 Pt.), and to control of fluid and electrolytes, the clinical and laboratory findings were much improved within the two week's of admission. The prednisolone has been administered 80 mg a day at first on the 3rd days of admission,- and then decreased the dose until 20 mg once a day for all the 5 days. Both the patients were discharged on the 14th day of admission and all have good condition until one year after then.

Human epidermis is a continuously dividing tissue, in which the keratinocytes gradually differentiate and mature while moving from the basal cell compartment to the upper cell layers. However, cholesteatoma is characterized by the presence of squamous epithelium invading the middle ear. This epithelium is believed to have hyperproliferative properties. Using immunohistochemical techniques, we investigated the reaction pattern of monoclonal antibody to PCNA and cytokeratin 16 as proliferating markers, and of monoclonal antibody to cytokeratin 13 and DBA as basal cell markers in the cholesteatoma to determine whether the number of proliferating cells is increased, and whether proliferating cells are found beyond the basal cell layer in cholesteatoma. The results were as follows: 1) When the tissues were stained with the proliferating markers PC10 and K8.12, the normal epithelium of ear canal showed focal staining in the basal cell layer, whereas epithelium of cholesteatoma showed dense, diffuse staining not only in the basal cell layer but also in the suprabasal cell layer. 2) When the tissues were stained with the basal cell markers KS-1A3 and DBA, both epithelium of the normal ear canal and of cholesteatoma showed staining in only a single basal cell layer. These results suggest that increased epidermal cell proliferation in cholesteatoma may be due to increased proliferative activity in suprabasal keratinocytes as well as in the basal compartment.

수중에서 미세플라스틱인 Polypropylene의 Cd 흡착특성 평가

엄주현,박종환,김성헌,김영진,류성기,서동철 한국환경농학회 2019 한국환경농학회지 Vol.38 No.2

BACKGROUND: In recent years, studies on microplastics have focused on their decomposition in the ocean. However, no studies have been reported on the interaction between microplastics and metal ions in aqueous solutions. Therefore, this study was conducted to evaluate the adsorption capacity of cadmium(Cd) by polypropylene (PP) in aqueous solution. METHODS AND RESULTS: Cadmium adsorption characteristics of PP in aqueous solution were evaluated through various conditions including initial Cd concentration(1.25‐25 mg/L), contact time(0.5-24 h), initial pH(2‐6) and temperature(20‐50℃). Cadmium adsorption fit on PP was well described by Freundlich isotherm model with adsorption capacity(K) of 0.028. The adsorption amount of Cd by PP increased with increasing contact time, indicating that adsorption of PP by Cd was dominantly influenced by contact time. Especially, the removal efficiency of Cd by PP was highest at high temperature. However, the surface functional groups of PP before and after adsorption of Cd were similar, suggesting that adsorption of Cd by PP is not related to surface functional groups. CONCLUSION: Our study suggests that PP affects the behavior of Cd in aqueous solution. However, in order to clarify the specific relationship between microplastics and metal ions, mechanism research should be carried out.

김정은 정권의 보건의료 자원 확보 방안 연구

엄주현 세종연구소 2023 국가전략 Vol.29 No.2

During the more than 10 years of Kim Jong-un's regime, the healthcare system has been scrutinized, specifically healthcare resources, facilities, medicines, and personnel. Since the early days of his rule, the construction of a specialized hospital in Pyongyang signaled the desire to modernize healthcare facilities nationwide, but the intended modernization did not materialize as planned. However, following the failed North Korea-U.S. diplomatic efforts in 2019 and the outbreak of COVID-19 in 2020, there emerged a need for actual improvement and an opportunity to create an environment conducive to it. As a result, there have been changes in the names of healthcare facilities throughout the country. In terms of medicines, the introduction of the socialist responsibility system led to the production of medicines in pharmaceutical factories and their sales through pharmacies. Additionally, the legal sale of medicines was ensured through the revision of the pharmaceutical law, which will take effect in 2022. Regarding healthcare personnel, the regime encourages the use of advanced medical technology while emphasizing the importance of diligence and dedication. The shortage of funding for healthcare services continues to be offset by the passion of healthcare workers. 김정은 정권 10여 년 동안의 보건의료체계 중 보건의료 자원, 그중 변화가 큰 시설과 의약품, 인력을 검토했다. 병원 등의 시설은 집권 초기부터 평양에 전문병원을 건설해 새로운 지도자의 집권을 알렸고 이를 모범으로 전국의 시설을 현대화하고자 했다. 하지만 현장에서는 정권의 의도대로 집행되지 않았다. 하지만 2019년 북미관계 개선 실패로 내치에 집중하게 됐고 2020년 코로나19를 겪으며 실질적인 정비의 필요성과 환경이 조성됐다. 그 결과, 현재에는 전국의 보건의료 시설 명칭이 바뀌었다. 의약품의 경우 사회주의책임관리제가 도입되면서 제약공장에서 의약품을 생산해 약국을 통해 판매하고 있으며 2022년에는 의약품법을 수정해 판매를 법적으로 담보했다. 의료인의 경우 선진 의학기술로 무장할 것을 독려하는 동시에 성실성과 헌신성을 강조하며 보건의료 서비스 운영에 소요하는 재원을 여전히 의료인의 열정으로 상쇄하고 있음을 확인할 수 있었다.

본 연구는 사용자의 에너지 절감 행동 유도를 위하여 가정의 전기 에너지 사용량을 두 가지 시각 유형의 에너지 피드백 디자인으로 제작하고, 이에 따라 인구통계학 요인별 피드백 전략 도출을 목표로 한다. 선행 연구 고찰을 통해 유형화한 이성 소구 피드백과 감성 소구 피드백은 각각 바(bar) 그래프와 북극곰 위젯(widget) 디스플레이로 디자인하였다. 피드백 유형의 시각적인 차이에 근거한 사용자의 이해도, 선호도, 절전의도를 알아보기 위하여 설문지 실험 후 결과를 도출하였다. 실험 결과, 이성 소구 피드백은 낮은 연령과 공학/사회과학 분야의 사람에게 높은 이해도를 보였다. 감성 소구 피드백은 낮은 연령일수록 높은 이해도를 보였으며 여성이 남성보다, 인문/예술 분야가 다른 분야보다 선호도가 높게 나타났다. 최종적으로 연구 결과를 바탕으로 네 가지 에너지 피드백 전략을 도출하였다. This study aims to draw up energy feedback strategies on demographic factors through two visualization types of energy feedback for inducing energy saving behaviors. Through the background study, we analyzed visual types for energy feedback design and these types are classified into Rational Appeal Feedback and Emotional Appeal Feedback. Each of feedback types is designed as Bar Graph and Polar Bear Widget Display. This study draws conclusions through online survey method for evaluating user`s understanding, preference and behavior intention based on visual distinction. Firstly, the understanding of rational appeal feedback among under age 20 is better than 30 age or older. People in engineering or social sciences major/occupation have a high degree of understanding of rational appeal feedback. Secondly, emotional appeal feedback draw up high understanding with low age. In the case of preference, women were higher than men, and the major/occupation of humanities and arts had a relatively higher average value than other fields. Thirdly, as a result of analyzing the correlation between variables of each feedback type, there were high correlation between understanding, preference, and behavior intention of each feedback type. Finally, feedback strategy for each type of users is derived according to the experimental results.
