This work aimed to analyze current status of by-products generation and industrial symbiosis network in Gyeongsangbuk-do, South Korea. Manufacturing sector of the province mainly consists of electronics, machinery, steel, metal-working industries. Gumi and Pohang have the 1st and 2nd largest worker population in the manufacturing sector. 21,950.7 ton/d of waste is generated from the industries in 2011, of which 82.2% is recycled. The industrial waste, which is not recycled, is mainly composed of sludge cake from domestic wastewater treatment plants, waste plastic, incinerator ash, and slag. Pohang is the largest generating city of both total and the non-recycled industrial waste in the province, and most of the waste is from Pohang steel industrial park. Symbiosis map in Pohang steel industrial park shows that most of the current material symbiosis in the industrial park is for waste refractories and slag.

The purpose of this study is to find out problems in obesity management through survey and analysis of the actual conditions from the view of a elementary schools school-nurses and to establish fundamental data for efficient obesity management. The subjects for this study were 313 numbers of elementary school-nurses in Kyung-Sang-Pook-Do. The data were collected through mail questionaries from November 1 to November 30,1997. The major findings in this survey were as follows:49.8% of the school-nurses who responded in the survey were in their 30s. The average career was 7.3years. The average service duration in their present school was 2.3years 55.6% of them were serving at schools which have less than ten classes total. 77.2% of them were serving rural areas, 79.6% of them were serving at schools with fewer than 100 obese students. The total obesity prevalence rate was 11.4%, 13.3% were girls, 9.3% were boys. The measurement of height and weight is performed once a year for all surveyed students(91.7%), but obese students were measured as much five times(51.1%). The rate of obesity management planning was 74.1%,however the rates of evaluation and role assignment were 41.2%, and 24.3% 79.6% of the surveyed schools have health education classes for obesity, the rate compared(8.0 periods per year) to the whole of health education(79.1 periods per year) is 10.1%. 99.9% of the schools had counseling rooms for obesity (combined with nursing rooms) but they were used. The roote of individual counseling was 84.3%. The frequency counseling was six times a year for about 15 minutes. Obesity counseling records were kept 93.6% of the time and individual information cards were kept 98.7% of the time. The frequency of parents counseling was 42.8% and the survey shows that the main problem here was insufficient counseling facilities. The frequency of dietary guidance and exercise therapy was 84.3% and the dietary instructor was usually the school nurse at 51.7%. The frequency of obesity student exercise was 1~2 times a week and more-than-10minutes at a time. They skip rope during the morning self-study class. The number on problem of exercise guidance at 56.2% was students' non-cooperativeness. School-nurses,87.9%, answered that obesity management at school is necessary and 86.9% mentioned the shortage of obesity related information in present physical exercise books. From the plural responses of executing the obesity management, there are many similar problems; lack of knowledge and non-cooperation in parents at 41.9%, is predominant followed by of knowledge and non-cooperation in the children. The third problem is the lack of funds and facilities.

전이온도가 72K인 고온초전도체 Y?P?B?Cu?O?에서 초전도성을 감소시키는 Pr원소자리에 Ca과 Zn를 적당히 치환시켜 자기적 성질을 연구하였다. 초전도 전이온도(Tc)는 Ca이 치환된 시료의 경우 80~85k의 범위에서 측정되었으며, Zn가 치환된 경우에는 35~49K의 값을 보였다. 비저항의 온도 변화로부터 결정된 전기적 전이온도는 온도에 대한 자기모우먼트으 변화에서 구한 자기적 전이온도와 비슷한 값을 보였다. 자기이력곡선으로부터 Bean의 모델을 이용하여 Hcl(저임계자기장), Hc?(고임계자기장), 반자성정도, 임계전류밀도를 측정하였다. 이러한 성질들은 시료 내에 Ca의 치환량이 많아질수록 증가하였으며, Zn가 많아질수록 급격히 감소하였다. 특히 임계전류밀도는 x=0.0인 시료는 1.60x10?A/㎠이었으며 Ca이 치환된 시료는 1.30~1.98x10? A/㎠, Zn가 첨가된 시료는 3.5x10?~1.3x10?A/㎠의 값으로 계산되었다. 이것은 시료 내에서 Ca은 초전도성을 증가시키고, Zn는 초전도성을 감소시키는 것을 의미한다. We have studied magnetic properties as a appropriate substitute of Ca and Zn element for Prelement which reduces superconducting properties in the high-temperature superconductor Y?Pr?Ba?Cu?O? of transition temperature 72K. When Ca is put into, the critical temperature(Tc)showed the value of measurement at the range of 80~85K while for Zn the Tc had the range of 35~49K. The electric critical temperature determined by the temperature dependence of resistivity had a similar data to the magnetic field), Hc?(high critical magnetic field), diamagnetic ratio and critical current density have observed by Bean's model from the magnetic hysterisis curve. These properties were increased with adding Ca and abruptly decreased with adding Zn in the samples. Especially, the critical current density of x=0.0 sample was calculated at 1.60x10?A/㎠ and those of the other Ca-added samples at the range of 1.30~1.98xA/㎠and those of Zn-added samples at the range of 3.50x10?~1.30x10?A/㎠. These mean that Ca increases supercondecting properties in the sample and Zn element decreases them.

Jae-Hyoun Park,신장규,Hoon Kim,In-Soo Wang,최평,Sang-Ho Seo,Young-Chang Jo 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.44 No.1

An active pixel CMOS image sensor in which a PMOSFET is used as a photodetector is described. The photodetector is congured by using a oating gate/n-well tied PMOSFET. The designed photodetector has IDS-VDS characteristics similar to those of a general PMOSFET when the incident light power, instead of the gate voltage, is supplied. A 1 16 image sensor array was designed and fabricated using 1-poly and 2-metal 1.5 m CMOS technology. The unit pixel of this sensor consists of a PMOSFET photodetector and 4 NMOSFETs, its area is 86 90.5 m, and the ll factor is 12 %. A highly sensitive pixel is feasible owing to the relatively small area of the photodetector and the pixel circuit with voltage gain.

식물인 Pistiacia lentiscus L. var. Chia.는 그리이스 키오스 섬의 남부지방에서만 서식하며, Chios gum mastic (CGM)으로 알려져 있는 수지를 만들어 낸다. Pistacia lentiscus 나무의 줄기와 잎에서 추출한 천연물질인 CGM은 과거 수세기 동안 지중해와 중동 지역 국가들에서 음식 첨가물과 치료약으로 광범히 하게 사용되어 왔었다. 본 연구는 사람구강편평상피암종세포(YD9 cells)에서 CGM의 세포독성과 성장억제 효과, 그리고 세포주기의 변형과 세포자멸사(apoptosis)에 대한 분자생물학적 기전을 알기 위해서 수행하였다. YD9 세포와 사람정상각화세포(HaCaT)의 생존률 측정은 MTT법을 시행하였고, YD9 세포의 성장억제를 확인하기 위해서는 clonogenic assay를 사용하였다. 세포자멸사가 유도되는 YD9 세포를 관찰하기 위해서 hoechst 염색법과 DNA 전기영동법을 사용하였다. 그리고 YD9 세포에 CGM을 적용한 후, Western blot 분석, 세포면역화학염색, 공점레이저주사현미경 검경, FACScan flow cytometry, 사립체막 전위변화, proteasome 활성도 측정 등을 시행하였다. CGM으로 처리된 YD9 세포는 용량 의존적인 세포 성장억제와 세포자멸사에 의한 세포죽음을 보였고, caspase-9, caspase-3, PARP 그리고 DFF45 (ICAD)의 파괴와 분절의 생성, DNA의 조각남, 핵 응축, 사립체막전위의 감소, Bax와 Bcl-2의 분율의 변화, cytochrome c의 사립체에서의 세포질로의 유리, AIF와 DFF40 (CAD)의 핵으로의 이동과 같은 세포자멸사 증거를 보였다. Flow cytometry 분석에서는 cyclin D1, cyclin D3, Cdk2 그리고 Cdk4의 발현의 감소와 p21<SUP>WAF1/CIP1</SUP>와 p53의 발현 증가와 관계있는 것으로 보여지는 G1 세포주기 정지를 보였다. 이러한 결과는 CGM이 세포주기 관련 단백질들의 변형을 유도한 G1 세포주기정지와 사립체와 caspase 경로를 통한 세포자멸사를 유도함을 명확하게 증명하고 있다. 이와 같은 강력한 세포주기 정지와 세포자멸사 유도능은 CGM이 사람구강편평세포암종의 새로운 치료전략으로서의 가능성을 높여 준다고 생각한다. Chios gum mastic (CGM) is obtained from the stem and leaves of Pistacia lentiscus trees and has been extensively used for centuries in Mediterranean and Middle Eastern countries, both as a dietary supplement and herbal remedy. This study was undertaken to examine in vitro effects of cytotoxicity and growth inhibition, and the molecular mechanism underlying modulation of cell cycle and induction of apoptosis in YD9 human oral squamous carcinoma cell line treated with CGM. The viability of YD9 cells and human normal keratinocyes (HaCaT cells), and the growth inhibition of YD9 cells were assessed by the MTT assay and clonogenic assay respectively. The hoechst staining and DNA electrophoresis were conducted to observe the YD9 cells undergoing apoptosis. YD9 cells were treated with CGM, and Western blotting, immunocytochemistry, confocal microscopy and FACScan flow cytometry were conducted. Mitochondrial membrane potential change and proteasome activity were measured. CGM treatment on YD9 cells resulted in a does-dependent inhibition of cell growth and induced apoptotic cell death. And tested YD9 cells showed several lines of apoptotic manifestation. Flow cytometric analysis revealed that CGM resulted in G1 arrest in cell cycle progression which was associated with decrease in the protein expression of cyclin D1, cyclin D3, Cdk2 and Cdk4, and increase in the protein expression of p21<SUP>WAF1/CIP1</SUP> and p53. These results demonstrate that CGM induces G1 the cell cycle arrest via the modulation of cell cycle-related proteins, and apoptosis via mitochondria and caspase pathway in YD9 cells, suggesting that CGM can be considered as a novel therapeutic strategy for human oral squamous cell carcinoma from its strong cell cycle arrest and apoptosis-inducing activity.
