  • Resistive random access memory (ReRAM)는 낮은 동작 전압, 빠른 동작 속도, 고집적화 등의 장점으로 인해 차세대 비휘발성 메모리 소자로써 많은 관심을 받고 있다. 최근에 ReRAM 절연막으로 NiOx, TiOx, AlOx TaOx, HfOx와 같은 binary metal oxide 물질들을 적용하는 연구가 활발히 진행되고 있다. 특히, HfOx는 안정적인 동작 특성을 나타낸다는 점에서 ReRAM 절연막 물질로 적합하다고 보고되고 있다. ReRAM 절연막을 형성할 때, 물리 기상 증착 방법 (PVD)이나 화학 기상 증착법 (CVD)과 같은 방법이 많이 이용된다. 이러한 증착 방법들은 고품질의 박막을 형성시킬 수 있는 장점이 있다. 하지만, 높은 온도에서의 공정과 고가의 진공 장비가 이용되기 때문에 경제적인 문제가 있으며, 기판 또는 금속에 플라즈마 손상으로 인한 문제가 발생할 수 있다. 따라서 이러한 문제점들을 개선하기 위해 용액 공정이 많은 관심을 받고 있다. 용액 공정은 공정과정이 간단할 뿐만 아니라 소자의 대면적화가 가능하고 공정온도가 낮으며 고가의 진공장비가 필요하지 않은 장점을 가진다. 따라서 본 연구에서는, 용액공정을 이용하여 HfOx 기반의 ReRAM 제작하였고 $25^{\circ}C$$85^{\circ}C$에서 ReRAM의 동작특성에 미치는 compliance current의 영향을 평가하였다. 실험 방법으로는, hafnium chloride (0.1 M)를 2-methoxyethanol에 충분히 용해시켜서 precursor를 제작하였다. 이후, p-type Si 기판 위에 습식산화를 통하여 300 nm 두께의 SiO2 절연층을 성장시킨 후, 하부전극을 형성하기 위해 electron beam evaporation을 이용하여 10/100 nm 두께의 Ti/Pt 전극을 증착하였다. 순차적으로, 제작된 산화물 precursor를 이용하여 Pt 위에 spin coating 방법으로 1000 rpm 10 초, 6000 rpm 30초의 조건으로 두께 35 nm의 HfOx 막을 증착하였다. 최종적으로, solvent 및 불순물을 제거하기 위해 $180^{\circ}C$의 온도에서 10 분 동안 열처리를 진행하였으며, 상부 전극을 형성하기 위해 electron beam evaporation을 이용하여 Ti와 Al을 각각 50 nm, 100 nm의 두께로 증착하였다. ReRAM 동작에서 compliance current가 미치는 영향을 평가하기 위하여 compliance current를 10mA에서 1mA까지 변화시키면서 측정한 결과, $25^{\circ}C$에서는 compliance current의 크기와 상관없이 일정한 메모리 윈도우와 우수한 endurance 특성을 얻는 것을 확인하였다. 한편, $85^{\circ}C$의 고온에서 측정한 경우에는 1mA의 compliance current를 적용하였을 때, $25^{\circ}C$에서 측정된 메모리 윈도우 크기를 비슷하게 유지하면서 더 우수한 endurance 특성을 얻는 것을 확인하였다. 결과적으로, 용액공정 방법으로 제작된 ReRAM을 측정하는데 있어서 compliance current를 줄이면 보다 우수한 endurance 특성을 얻을 수 있으며, ReRAM 소자의 전력소비감소에 효과적이라고 기대된다.

  • This study presents a comparative analysis of enforcement and regulatory compliance issues in Korean and American fisheries. The comparison involves characterizing factors which affect regulatory compliance. The study also suggests policy directions and strategies by characteristics of factors suitable to Korean fisheries circumstances in order to induce voluntary compliance from fishers and to make compliance friendly environment for the fishers. In detail, this study has 3 steps as follows. First, this study characterizes factors influencing compliance and non - compliance caused by various reasons and categorizes these factors by considering theories for fisheries regulatory compliance. Major categories of compliance factors consist of fisheries resources, users(fishers), and the government. Each category is composed of several factors and sub - factors by characteristics. Second, this study seeks to diagnose problems and limitations from the regulatory compliance in Korean and US' fisheries by analyzing the current status of the compliance in both countries. The comparative analysis between two countries highlights the problems and limitations of each country's regulatory compliance and leads to implications for Korean fisheries. Third, this study suggests policy directions and strategies suitable to Korean regulatory compliance environment through detailed understanding of U.S.' fisheries regulatory compliance. The suggested strategies are based on the concept of voluntary compliance and compliance - friendly environment, not command and control regulations. Furthermore, this study provides policy suggestions for Korean fisheries regulatory enforcement and compliance issues.

  • OSHMS(Occupational Safety and Health Management System) is able to define as a typical convergence of all kinds of activities and elements that support maintaining safety at workplace and protecting employee's health. In particular, fundamental function of OSHMS is preventing diverse hazards at workplace through high level of regulation compliance. Furthermore, insuring safety in workplace, protecting employee's health and increasing effectiveness in manufacture are OSHMS's additional functions. Based on the division of manufacture in 2009 Survey on Current Status of Occupational Health & Safety data, the study analyses certain relation between OSHMS and level of regulation compliance. The main finding is that most activities and elements which formed by OSHMS are being affected by regulation clauses.

  • Background: A well-designed shift schedule has been reported to have a positive effect on improving health problems associated with shift work. This study aimed to identify compliance with the 17 recommendations on work schedule (WSRs) for shift nurses and related factors. Methods: The descriptive study was conducted with 182 nurses who worked in three shifts for more than 1 year at superior general and general hospitals in three regions. Data were collected with selfadministered questionnaire and 13-week work schedule tables, and analyzed with both person- and cycle-based compliance. Results: Person-based compliance was 11.77 among 17 items in total. However, no one completely complied with WSRs of "no work on weekends" and which showed the lowest cycle-based compliance (22.3%). Compliance with some WSRs was related to hospital type, proportion of nurses in school and having standards on work schedule at institutional level. Conclusion: Compliance with WSRs of shift nurses in Korea is still unsatisfactory, and one day off after night shift and work on weekend are quite common. Hospitals should keep the standards on work schedule, monitor compliance with standards, and try to introduce modified shift systems to improve the current problems.

  • Background : The purpose of this study was to investigate the current status of medication compliance of outpatients and to analyze the factors contributing to medication non-compliance Methods : Telephone survey was conducted to the 1,000 outpatients who visited medical institutions during the period from January 2002 to April 2002. Subjects were randomly selected from the telephone directories of the nation, and the socio-demographic characteristics of the respondents such as age, gender and region were matched based on those of outpatients in 2001. Results : The results of survey revealed that those who complied with doctors' regimen in the right way accounted for 82.4%. The compliance increased with the strong belief in the medication, less unwanted side effects and inconvenience, more severity of disease, and lower perceived health status. Compliance rate was also higher in the patients group who experienced the drug education by the pharmacists than those who did not. Conclusion : In order to improve drug compliance, drug information on efficacy, adverse reaction, drug interactions, and basic disease information are to be provided to the patients. Drug education needs to be focused not only on providing knowledge of drugs and diseases but also changing attitude on drug use of the patients.

  • The unloading compliance method is the most commonly used method to evaluate the fracture resistance characteristics of a material. In dynamic loading condition, the direct current potential drop(DCPD) method has been used because the unloading compliance method can not be applied due to the discontinuity of loading. However, even in the dynamic test using DCPD method, there is a problem that the voltage drops sharply on the initiation of crack. For the reason metioned above, the normalization method was suggested on ASTM E 1820 which is revised recently, as a new method to evaluate the dynamic fracture resistance characteristic. The nomalization method can be used to obtain a fracture resistance curve directly from a load-load line displacement. In this study, we obtained two fracture resistance curves from static test of welding part of nuclear piping both by unloading compliance and nomalization method. The two curves were almost same each other, so the adaptability of the nomalization method has been proved. We conducted a dynamic fracture resistance test for the same material. The fracture resistance curve from the dynamic test was obtained by normalization method and compared to that of the static test result.
