기후-전구대기화학모델을 이용하여 엘니뇨가 대류권 오존에 미치는 영향을 분석하였다. 40년간(1971-2010) 대류권 오존을 EOF 분석한 결과에서 열대 중앙-동태평양에서 오존의 감소가 관측과 유사하게 잘 모의되었다. 그러나 인도양-인도네시아 부근의 오존 증가는 관측에 비해 약하게 모의되었다. 엘니뇨에 의한 오존변동 과정을 이해하기 위하여 2006년 엘니뇨의 경우를 좀 더 자세히 분석하였다. 엘니뇨의 발생 시 중앙-동태평양의 오존 감소는 활발해진 상승운동과 그에 따른 수증기량 증가로 오존의 체류시간이 짧아졌음에 기인하였다. 해수면 온도 강제력으로 유도된 하강기류 편차와 수증기 감소로 인도양 대류권 상층 오존이 증가하였다.

근대 서구 화학자들의 저서가 한역(漢譯)되면서 다량의 새로운 화학원소를 표 기하는 단어(한자)들이 생겨났다. 그들은 중국어의 어휘를 더욱 풍부하게 하는 동 시에 중국어 어휘에서 없어서는 안될 주요성분으로 자리 잡았다. 초창기 화학원소 를 표기하는 어휘(한자)는 한자와 어휘를 동시에 생산하는 매우 독특한 형식으로 진행되었다. 본문은 당시 화학원소를 명명했던 근거와 그 어휘들에게 나타난 독특한 한자와 어휘의 관계를 고찰하였다.

Laboratory equipment will continue to be developed and created as long as experiments continue. Up until now, the designs have been focused on the functional role; successfully process the study purpose. However, nowadays, the requirements of providing emotional satisfaction of the design, has increased. Even so, the users are normally limited by specific groups and investments on these designs have been neglected due to small annual production by the small market. Through this study, we have conducted an emotional evaluation on Temperature and Humidity Chamber's (TH Chamber) exterior shape. First of all, we extracted emotional words and placed them in categories that represent these emotions and conducted an emotional evaluation on four typical TH chamber models. They were selected based on its door lock type and control box type. The result showed that the 'fixed type' of control box and the 'handle type' of door lock were most favorable by the users, satisfying the five representative emotions; 'Attractiveness', 'Classiness', 'Comfortableness', 'Pleasant' and 'Satisfaction in Usability'. Particularly, all 4 emotional words in the 'Satisfaction in Usability' category recorded over 3.65. This indicates that Satisfaction in Usability is relatively an important category when expressing laboratory equipment. The result of this research is expected to be used as a basic data to find a way of right approach in laboratory equipment design.

In the microelectronics packaging industry, the adhesion strength between Cu and polyimide and the thermal stability are very important factors, as they influence the performance and reliability of the device. The three different buffer layers of Cr, 50%Cr-50%Ni, and Ni were adopted in a Cu/buffer layer/polyimide system and compared in terms of their adhesion strength and thermal stability at a temperature of 300˚C for 24hrs. A 90-degree peel test and XPS analysis revealed that both the peel strength and thermal stability decreased in the order of the Cr, 50%Cr-50%Ni and Ni buffer layer. The XPS analysis revealed that Cu can diffuse through the thin Ni buffer layer (200Å), resulting in a decrease in the adhesion strength when the Cu/buffer layer/polyimide multilayer is heat-treated at a temperature of 300˚C for 24hrs. In contrast, Cu did not diffuse through the Cr buffer layer under the same heat-treatment conditions.

Current trends of analytical chemistry for environmental protection in Korea were briefly reviewed. Additionally, overview of the policies and efforts of the Ministry of Environment (MOE) of the Korean Government for environmental conservation and for improvements of water and air qualities is also discussed. Particularly, this review focuses on the current standing and central trends of analytical chemistry for air quality protection.

극지 환경계에서 발견되는 수은의 농도분포는 봄철 극단적인 소멸과 여름철 고농도의 발현과 같이 특이한 분포 특성을 취하는 것으로 밝혀지고 있다. 이와 같은 극지환경의 계절적 농도분포특성은 일반적으로 알려진 수은의 대기환경학적 특성과 상치되는 현상이다. 본문에서는 북극지역에서 장기간 관측된 수은의 농도자료와 이에 대비한 비교 자료 군으로 서울지역을 중심으로 장기 관측된 자료들을 동시에 이강하여, 극지역 수은분포의 특이성과 환경학적 의미를 여러 가지 관점에서 다양하게 고찰하였다.

In order to study the effects of Aloe vera Linne treatment on the clinical chemistry in patients with liver disease, seven patients were administered orally with 800-1, 600 mg of Aloe vern Linne four times a day for six months. The high levels of serum AST, ALT, ALP, γ-GTP and total bilirubin in patients were significantly reduced by administration of Aloe vem L.. The reduced serum albumin/globulin value was increased by Aloe vera L. treatment. But other blood parameters of clinical chemistry values were not affected by Aloe very L. treatment. These data suggest that Aloe very L. can be effective in treatment of the patients with liver disease.

The HII region S140 and the associated molecular cloud L1204 have been observed with 10 molecular transitions, CO (1-0), 13CO (1-0), C18O (1-0), CS (2-1), HCO+ (1-0), HCN (1-0), SO (22-11), SO2(220-313), OCS (8-7), and HNCO (404-303) with ~ 50" angular resolutions. More than 7,000 spectra were obtained in total. The morphology of this region shows a massive fragment (the S140 core) and the extended envelope to the northeast. Several gas condensations have been identified in the envelope, having masses of ~103M⊙ and gas number densities of ≾104cm-3 to 3×105cm-3 in their cores. The column densities of the observed molecular species toward the S140 core appear to be the typical warm clouds' abundances. It seems to be that the S140 core and L1204 have been swept up by an expanding shell called the Cepheus bubble. The large value of LIR(embedded stars)/Mcloud ~5 L⊙/M⊙ of the S140 core may suggest that the star formation has been stimulated by the HII region, but the shock velocity and the pressure of the region seem to give a hint of the spontaneous star formation by the self gravity.

In order to study the effects of Aloe vera treatment on blood glucose level and clinical chemistry in diabetic patients, eight diabetic patients were administered orally with 800 mg of Aloe vera three times a day for three months. The high levels of blood and urine glucose in diabetic patients were significantly reduced by administration of Aloe vera. The increased plasma triglyceride concentration was also significantly reduced by Aloe vera treatment. A little amount of urine bilirubin, hematuria, nitrite, urobilinogen, protein and ketone bodies were detected before treatment, but not detected after Aloe vera treatment. But other blood parameters of clinical chemistry values were not affected by Aloe vera treatment. These data suggest that Aloe vera can be effective in the treatment of the diabetic patients,

본 논문에서는 ATiO3(A=Ca, Sr, Ba) 조성을 갖는 단순 페롭스카이트 구조에서 생성되는 격자결함 구조에 대하여 고찰하였다. 페롭스카이트 구조는 고충전밀도를 갖기 때문에 프렌클 결함은 고려되지 않았다. 쇼트키결함이나, 고유전자결함도 자연적으로 포함된 억셉타 불순물 농도에 비하면 무시할 정도로 적은 양이다. 실제적으로 전기적 특성에 영향을 주는 것은 전하적 결함을 발생하는 aliovalent 불순물이다. 삼성분계이기 때문에 양이온간의 비화학양론이 발생하며 BaTiO3나 SrTiO3에서 수백 ppm이내의 AO나 TiO2의 용해도가 관찰되나, CaTiO3에서는 상당량의 CaO와 TiO2의 용해가 가능하다.
