적외선 센서 제작을 위한 이방성 식각 기술을 조사하였다 단결정 실리콘 기판에 이방성 식각을 하기 위해서 KOH와 TMAH의 서로 다른 두 가지 식각액을 사용하였다. KOH용액은 TMAH용액과 비교하여 녹은 식각율을 보이지만 실리콘 산화막과의 Selectivity는 떨어진다 결론적으로 TMAH는 멤브레인층의 형성과 적외선 흡수체 구조를 만드는데 적당만 용액이다 We report on anisotropic etching technologies for the fabrication Infrared sensors Two different etching solutions were used for the anisotropic etching for single crystal silicon substrates - KOH (potassum hγdroxlde) and TMAH (tetra methγ1 ammonium hγdroxide) KOH presented the higher etching rates compared to TMAH, but has poor selectivity with silicon dioxide It is concluded that TMAH is more suitable solution for the formation of membrane layer on which infrared absorbing strurtures are constructed
Anisotropic etching characteristics of single crystal silicon by KOH and KOH-IPA Solutions
조남인,천인호 韓國眞空學會 2002 Applied Science and Convergence Technology Vol.11 No.4
이방성 습식 식각기술을 이용하여 멤버레인을 제작하기 위하여 KOH 용액 및 KOH-IPA 혼합용액을 사용하여 단결정 실리콘 기판을 식각하였다. 단결정 실리콘의 식각속도는 식각 용액의 온도와 농도에 좌우되었으며, 식각 용액의 농도에 따라 식각 형태와 패턴 형성 방향이 달라짐도 관찰되었다. 식각을 위한 표면패턴은 실리콘웨이퍼의 primary flat에 45°로 기울여 형성되었으며 KOH 의 농도가 20 wt%로 유지되었을 때, 식각 용액의 온도 80℃이상에서는 U-groove, 80℃ 이하의 온도에서는 V-groove 식각 형태가 형성되었다. 각 면에 대한 식각속도 차이에 의해서 생기는 hillock은 온도와 농도가 높아짐에 따라 현저하게 줄어들었다. For a formation of membrane structures, single crystal silicon wafers have been anisotropically etched with solutions of KOH and KOH-IPA. The etching rate was observed to-be strongly dependent upon tie etchant temperature and concentration. Mask patterns for the etching experiment was aligned to incline 45 on the primary flat of the silicon wafer. The different etching characteristics were observed according to pattern directions and etchant concentration. When the KOH concentration was fixed to 20 wt%, the U-groove etching shape was observed for the etching temperature of above 80℃, and V-groove shapes observed at below 80℃. Hillocks, which were generated at the etched silicon surfaces, has been deceased as the increasing of the etchant temperature and concentration.

Purpose : The elderly population in the Republic of Korea was over 8.3% in 2003. This segment is projected to grow to 14.4% by 2019, with average life expectancy at 77.5 years for men and 84.1 year for women. According to significant increases in elderly population over 80 years of age, the demand of expert care for the bedridden and those suffering from dementia will be increased. The expanding role of nurses caring for the elderly requires that we properly define the role of the gerontological nurse practitioner (GNP). Method : The authors collected and analyzed the following sources available from nations where systems have already been in place for the gerontological nurse practitioner: educational manuals, textbooks, research papers, and Web sites for American Nurses Credentialing Center and Gerontological Nurse Practitioners. Result : The facilities and settings where GNPs serve are in-patient and out-patient acute care settings, long term care facilities, respite care facilities, day care centers, home-care agencies, community centers for the elderly, continuing care retirement communities. Although there are differences in role by setting of service, GNPs are nurse clinicians, educators, counselors, coordinators, facility administrators, researchers, advisors in ethical decision making, health services managers, self-care trainers, preventative-care administrators, environmental managers, advocates, program evaluators, information providers, and emergency responders. Conclusion : The role and functions of GNPs according to the facilities and settings in South Korea should be analyzed and developed.

A total of 2,765 accessions were used as the initial set having both seed coat color and 100-seed weight data. As a result of molecular profiling using six SSR markers followed by stratification based on their usages, 335 accessions(12.1%) were selected by clustering based on UPGMA. Since 75 out of 335 accessions were mixed in phenotypic traits as a result of characterization, 260 accessions were finally set as a core set. This core set revealed nearly the same diversity compared with the other results on morphological traits of Korean soybean landraces. In total, 115 alleles(19.2 alleles per locus) were detected in the initial set and 79 alleles(13.2 alleles per locus) were detected in the core set. All 30 major alleles were present in the initial set and in the core set as well. In allele coverage, the core set was 71.4% of the initial set. These comparisons of number of alleles, gene diversity and coverage indicated that the core set represented the entire set well.

Two hundred and sixty Korean soybean landrace accessions were analyzed for polymorphism at 92 simple sequence repeat(SSR) loci. The 995 identified alleles served as raw data for estimating genetic diversity and population structure. The number of alleles at a locus ranged from three to 27 with a mean of 10.4 alleles per locus. $F_{ST}$ values estimated by analysis of molecular variance(AMOVA) using SSR data set were 0.018, 0.027, and 0.016 for usage, collection site and maturity groups, respectively, indicating little genetic differentiation. The model-based clustering analysis placed the accessions into three clusters(K=3) with 0.0503 of $F_{ST}$, indicating moderate genetic differentiation. Duncan's Multiple Range Test at K = 3 on the basis of 18 quantitative traits revealed that one cluster was mainly differentiated from the other two clusters by seed related traits and the other two clusters were differentiated from each other by biochemical traits. Genetic structure of Korean soybean landraces was differentiated by model-based clustering and supported by their phenotypic traits in part. This preliminary study could be the first step towards more efficient germplasm management and utilization of soybean landraces and helpful in association studies between genotypic and phenotypic traits in Korean soybean landraces.
