朱廷一,李喜鳳,申哲雨 충남대학교 농업과학연구소 1999 농업과학연구 Vol.26 No.1

벼 立毛中 보리 산파재배법은 파종노력 절감, 적기파종 및 포장조건 불량시 대체파종 등의 장점이 있지만 관행에 비하여 수량성이 낮고 연차간 變異가 큰 특징이 있다. 수량성을 향상시키기 위하여 栽培安定性을 높이는 관리기술이 요구되는데 우선 입모 확보와 둑새풀 방제체제 확립이 절실히 요구된다. 따라서 立毛率 향상시킬수 있는 요인, 다수확을 위한 적정 입모수 설정 및 둑새풀에 의한 감수정도 등을 구명코자 대전에서 올보리를 공시하여 벼 수확 1일전에 파종하고 이에 대한 결과는 다음과 같다 . 1. 볏짚피복과 진압에 의하여 출현율이 향상되었는데 볏짚피복효과가 진압효과에 비하여 높았고 추가진압으로 11% 증수 효과를 기대할 수 있었다. 2. 단위 면적당 적정보리 立毛數는 507개/㎡로 측정되었다. 3. 둑새풀 발생이 많을수록 수량이 감소되었는데 ㎡당 17~22본 발생시 21.8%, 6~11본 발생시 11.0%가 각각 감수되었다. This experiment was carried out to estimate the appropriate seedling stand and to find out the factors of good establishment and the reason of the reduction of yield by water foxtail. The seedling stands was improved by the ice straw mulching and treading by the tracks of combine. The effect of mulching was higher than the treading. The appropriate seedling stands for example yield were estimated about 507 plants per ㎡ and its yield was 24㎏/10a. The higher density of water foxtail, the less the grain yield; 21.8% by 17 to 22 water foxtail stands per ㎡ and 11.0% by 6 to 11 plants.

For integrated circuit fabrication process compatible with education and R & D purpose, its period must be shortened and its yield must be satifactory, too. For this purpose, this study carried out minimized 4-film masks, hence the fabrication process period was shortened. 4-film mask I.C fabrication is processed during 40 hours, containing MOSFET of various W/L, resistors, diodes, ring-oscillator. The threshold voltage of p-n junction diode is about 0.7[V] and the resistivity of polysilicon for self-aligned gate electrode is less than 10-³[Ωcm]. This paper contains the diffusion profile, thin film growth condition using electrical furnace and CVD system, wet and dry etching condition of the growth thin film, I-V, and C-V characteristics of MOS Transistor fabricated in this process. In MOS Transistor, the leakage current of gate oxide and various charges in the interface between gate oxide and silicon substrate are proposed as the most important problem, but these problems are overcome by repeated experimentation. MOS Transistor using AEO as an example of research experimentation have characteristics prior to the case using general dry oxidation gate.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

최근 세정환경의 변화로 납세자에 대한 서비스의 제공 등 많은 개혁을 시행하고 있으나 합리적이고 효율적인 세정을 위한 개혁조치는 납세자와 직접적으로 접촉하는 세무조사가 중심이 되며 이에 부합되는 공정하고 투명한 세무조사가 이루어지려면 세무조사와 관련한 제반절차의 합법성과 세무공무원의 전문성 및 투명성이 선행되어야 할 것이다. 본 연구에서는 효율적이고 합리적인 세무행정을 위하여 세무조사에 대한 선행연구와 각종 참고문헌을 통해 세무조사의 이론적 측면과 주요 국가의 세무조사제도 및 우리나라 세무조사세도의 개선방안은 다음과 같다. 첫째, 세무조사대상자 선정에 있어서 선정위원회(가칭)와 외부인사 등을 참여하는 제도를 법제화하여 객관성 있는 선정제도의 틀을 마련하여야 할 것이다. 또한 매년 초 공개한 선정기준에 의해 엄중한 세무조사를 실시하고, 연중 실시한 세무조사 결과 자료를 공개하고 피드백 시켜 익년 세무 조사선정기준을 정하는데 활용하도록 한다. 둘째, 세무조사평가방법에서는 조사실적에 대한 통제제도의 개선, 정기조사 심사분석 개선, 평가제외 규정을 확대함으로써 세무조사요원들이 실적에 부담을 갖지 않고 정확하고 공정한 세무조사를 할 수 있게 하여야 한다. 세무조사 대상자 선정위원회에서 세무조사대상자를 선정하는 명확한 규정을 법제화함으로써 세무조사에 대한 인식이 바뀌게 될 것이고, 세무조사를 시행하는데 실적위주의 부담이 줄어들게 되면 조사위원들은 보다 편한 마음에서 정확한 세무조사를 시행할 수 있게 될 것이다. Most of the taxes in Korea are collected using a voluntary reporting payment system that meets most financial requirements. However, many people are unaware of their tax liability, and legal forces to ensure payment of taxes are weak within the Korean social structure. Therefore, the tax system cannot depend only on people's awareness of their tax liability, and for these reasons the Korean government has been investigating a system for fair taxation and the administrative punishment for tax evasion. In addition, an improvement to the taxation system is strongly demanded in order to protect taxpayers' rights, and improve the efficiency and rationality of the system. In this study, I compare and analyze the problems related to each nation's tax investigation system, and then propose an improved plan for a tax investigation system in Korea. It is necessary to prescribe in the bylaws of the Office of National Taxation that the investigator's performance rating or incentives are not affected in any way by the tax investigator's actual records on tax collection, as this type of evaluation can easily lead to conflicts with the primary goals of the law or written constitution.

The purpose of this study was to evaluate the effects in respire-circulatory function and cadio-pulmonary endurance capacity. Twelve females(trained 6, untrained 6) participated in dancesport program that is 90min/day, 2day/week for 20weeks. The results were obtained as follow : 1. No significant difference was found in heart rate, ventilation and respiration rate among pretest, after 10 weeks and 20 weeks of dance program and between trained and untrained group. 2. Significant differenced was found in VCO₂between pretest and 20Weeks later in untrained group. 3. There was significantly increased VO₂max in 20 weeks dance program later compared with pretest and significant difference between groups. 4. There was no significant difference in ventilatory threshold and exercise time was not significant difference among trials and between groups. Conclusively, respiro-circulatory function and cardio-pulmonary endurance capacity were not changed at submaximal stage of excise test but those were significantly increased at maximal of exercise test during 20 weeks. Therefore, it is suggested that long term dancesport exercise program is expected more effective on the repiro-circulation function and cardio-pulmonary endurance capacity.

정보보호 수준을 측정하는 것은 매우 어려운 일로써 정보보호의 영역이 계속 확장됨에 따라 개념자체를 정의하기가 어렵고 아울러 다차원적인 요인을 포함하는 정보보호 지표 선정의 어려움, 시계열적인 통계 데이터 부족, 상이한 정보보호 지표를 하나의 지수로 통합하는 문제가 있기 때문이다. 그럼에도 불구하고 정보보호수준을 계량적으로 측정하기 위한 방법론으로 가장 적합한 것은 지수화하는 것이다. 이는 정책입안자나 정보보호 이해관련자들이 종합적인 측면에서 정보보호수준 목표를 결정하고 실행결과를 평가하는데 용이하기 때문이다. 본 연구의 목적은 정보보호정책 수립 및 평가의 기초 자료로 활용할 수 있는 지수를 산출하기 위한 종합적인 정보보호수준 평가지수 모델을 제시하고 지수를 산출하는데 있다. 지수산출결과, 정보보호수준은 2002년부터 2005년까지를 시계열적으로 보면 매년 평균 5.8%의 증가추세를 보이고 있다. 반면 역기능수준은 2003년 1.25 인터넷 대란으로 증가한 것을 제외하고 꾸준한 감소추세를 나타내고 있다. 특히 정보보호수준과 역기능수준이 발산하고 있어 정보보호정책이 유효하게 작용하고 있다고 판단되어진다.
