In this paper, we investigate the design and fabrication of a conical spiral antenna suitable for satellite TT&C applications. The shape of the spiral is optimized using a commercial electromagnetic software for good gain and axial ratio performances over $2.0{\sim}2.3\;GHz$ frequencies. A coaxial infinite balun feeding the spiral is designed using experimental methods. A method for precision fabrication of the spiral is presented. Measurements of the fabricated antenna show satisfactory performances over $2.0{\sim}2.3\;GHz$ such as a reflection coefficient less than -18 dB, a maximum gain greater than 4 dB, a gain greater than 0 dB over angles ${\pm}75^{\circ}$ from the antenna boresight, an axial ratio less than 5 dB over angles ${\pm}90^{\circ}$ from the antenna boresight, a front-back ratio greater than 15 dB.

Recent studies have shown that opiods can produce potent antinociceptive effects by interacting with opioid receptors in peripheral tissues. This study sougt to compare the effects of morphine with those of bupivacaine administered intraarticularly upon pain after arthroscopic knee surgery. In a ramdomized manner, 60 healthy patients received either morphine(3 mg in 20 ml NaCl ; n=20), bupivacaine(20 ml, 0.25% ; n=20) intraarticularly at the completion of surgery, and others were not administered(n=20) under general anesthesia after 1, 2, 4, 6, 12 and 24h of postoperative day, pain was assessed by a visual analogue pain scales, time to first analgesic use were recorded. Pain scores were significantly greater in the morphine group than two groups at 1h. From 4th until the end of the study period, pain scores were significantly greater in the bupivacaine group than in the other two group. Anagesic requirements were significantly greater in the morphine group than two groups at 1h but were significantly greater in the bupivacaine group than in the other groups throughout the remainder of the study period. The results suggest that intraarticular morphine produces an analgesic effect of delayed onset but of remarkably long duration.

Purpose: The purpose of this study was to investigate the food impaction between implant prostheses and adjacent natural teeth. Materials and methods: For this study, 51 patients with food impaction were selected and investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone level, proximal caries, marginal ridge distance and occlusal relationships. Results: Food impaction was found in the upper teeth (60.7%) more than the lower teeth (39.2%). Food impaction was occurred on mesial side of implant prostheses (86.2%) more than distal side (13.7%). Food impaction was mostly found in loose or open contact area (94.2%). Food impaction was frequent on stepped relationship between implant and adjacent teeth. Conclusion: Treatment plan should include proper adjacent and antagonistic occlusal plane and occlusal surface, to prevent food impaction, and the plan should include less adjacent tooth mobility with proper tightness between implant prostheses and adjacent teeth.

Postoperative brain damage is one of most serious complications of cardiopulmonary bypass (CPB). To prevent brain damage during CPB, adequate cerebral perfusion for cerebral oxygen demand should be maintained. This study monitored jugular venous oxyhemoglobin saturation ($SjO_2$), which reflects the overall balance of cerebral oxygen supply and demand, intermittently in 10 patients undergoing cardiac surgery. At the initiation of CPB, in spite of a significant decrease in mean arterial pressure, $SjO_2$ did not change, and it was stable during the hypothermic period of CPB. But a significan reduction in $SjO_2$ was observed during the rewarming period, and $SjO_2$ had an inverse linear correlation with esophageal temperature. Furthermore, the percent decrease of $SjO_2$ was related to rewarming speed. Therefore, therapeutic approaches for $SjO_2$ desaturation include slower rewarming, increasing cerebral blood flow, decreasing the cerebral metabolic rate for oxygen, increasing oxygen content, and increasing perfusion flow rate.

최근 중합효소연쇄반응을 이용한 분자생물학적 유전자분석기술의 발달로 성염색체상의 유전좌위 증폭을 통한 성별감정이 활발히 이루어지고 있다. 그중 사람 Y염색체상에 존재하는 남성 고환의 형성을 유도하는 sex-determining region Y(SRY) gene이 규명되어 유전질환의 조기 발견이나 예방 및 태아의 성별판정 등에 응용되고 있다. 그러나, 치아는 외부 환경에 대한 저항성이 가장 높은 장기로 성별감정 등 법의치과학적 개인식별에 널리 이용되고 있음에도 불구하고, SRY 유전자를 이용하여 치아에서의 성별감정에 대한 연구는 시도된 바 없다. 따라서, 본 연구에서는 사람 치아에서 중합효소연쇄반응법을 이용한 SRY 유전자를 검출하여 성별판정에 용용하고자 하였다. 남녀 각각 20개 치아의 치수와 상아질에서 DNA를 추출하여 중합효소연쇄반응 을 시행하고 SRY 유전자를 검색한 결과, 남성에서는 치수 13개중 8개, 상아질 7개중 4개에서 SRY 유전자가 검출되었고, 여생에서는 검출되지 않았다. 이러한 결과는 중합효소연쇄반응법을 이용하여 사람 치아에서 SRY 유전자를 검색할 때, 남성판별에 유용하고 치아를 이용한 성별감정시 기존의 성별감정에 이용되고 있는 다른 유전자와 함께 SRY 유전자를 검색함으로써 성별감정의 신뢰도를 높힐 수 있을 것으로 사료된다.

The purpose of this study was to determine whether parenting stress is related to anxiety in children with ADHD. The data were provided by 112 children between the ages of 7 and 9. Forty nine children with a diagnosis of ADHD were recruited through 3 departments of child psychiatry and 63 normal children were recruited from elementary schools from the same city. The Korean version of Parenting Stress Index-Short Form was used to assess parenting stress and the Korean version of the State Trait Anxiety Inventory for Children was used to assess the level of anxiety. The results show that children with ADHD have significantly higher levels of anxiety and parenting stress than normal children. However, no significant differences in parenting stress and anxiety were found across gender, age, and the type of ADHD. Significant correlation was found between trait anxiety and parental distress and between state anxiety and difficult child. Parenting stress didn't significantly influence on anxiety in children with ADHD. Occupational therapist need to consider that the anxiety level of children with ADHD is different from normal children. It is needed for interventions for children with anxiety symptoms and also consultation and intervention for parents with parenting stress.

In this paper, the system level EMC radiated emission test results of KoDSat(Korea Demonstration Satellite), its affects upon the Launch vehicle and H/W improving methods regarding its over exceed value of EMC specification are discussed. Regarding its over exceed value, we estimated that DAU of KoDSat generated the exceeded EMC noise source, and these test results were analyzed using the EMC2000 tool to find out how did it affect the FTS(Flight Termination Subsystem) of KSLV-1(Korea Small Launch Vehicle). To diminish the EMC noise source of UHF(430.1Mhz) band level, we redesigned the DAU power board to be applied the various schemes for EMI noise reduction such as grounding, shielding and EMI filtering, and also verified these reworks to analyze its diminishing affects in UHF band level by means of performing the DAU box level EMC test and performing the second KoDSat's system level EMC test.

플라즈마는 미세 전기 소자 제작에 있어 박막의 증착, 식각, 세정등 여러 가지 공정에서 널리 사용되고 있다. 미세 소자의 선폭의 감소와 높은 생산성을 위한 웨이퍼 면적의 대형화가 진행됨에 따라 플라즈마의 균일도는 공정 수율 향상의 관점에서 중요한 요소로 그것의 계측과 공정 중 실시간 감시에 필요성이 부각되고 있다. 플라즈마에 존재하는 라디칼의 밀도, 이온의 밀도, 전자 온도 등의 웨이퍼 상에서의 공간 분포와 공정 결과물과의 상관관계에 대한 연구는 현재까지 다양하게 진행 되었으며 특히, 라디칼의 공간 분포가 공정 결과물의 균일도와 큰 상관 관계가 있는 것으로 알려져 있다. 라디칼의 농도 분포를 계측은 레이저 유도 형광법, 발광 분광법, 흡수 분광법 등을 통하여 이루어져 왔으며, 특히 발광 분광법의 경우 계측의 민감성, 편의성등을 이유로 가장 널리 사용되고 있다. 그러나 현재 까지 진행된 발광 분광법을 이용한 라디칼의 공간 분포 계측은 그 자체로 공간 분포를 계측하는 것이 아닌 플라즈마 밀도의 축 대칭성을 가정하여 Abel inversion을 적용하거나, 광섬유를 플라즈마에 직접 삽입하는 방식을 사용하기 때문에 실제 반도체 제작공정을 비롯한 미세소자 공정 플라즈마의 라디칼 밀도 분포를 실시간, 비 접촉 방식으로 계측 하는데 한계가 있다. 본 연구에서는 반도체 공정 플라즈마의 밀도 균일성 분석을 위한 공간 분해 발광 분광기를 제안한다. 기존의 발광 분광법과 비교하여 공간 분해능 향상을 위하여 직렬로 설치된 다수의 렌즈, 개구, 그리고 핀홀을 이용하였다. 공간 분해 발광 분광기의 공간 분해능을 계산하였으며, 실험을 통하여 검증 하였다. 또, HDP CVD를 이용한 $SiO_2$ 박막 증착 공정에서 산소 라디칼의 농도와 증착된 박막의 두께 분포의 상관 관계를 계측 함으로써 공간 분해 발광 분광기의 플라즈마 공정 적용 가능성 입증 하였다.

'True education', which was the core ideology of 'the Korean Teachers & Educational Workers Union', is re-appropriated in the new media era. This word, which is actively used by young people, means 'punishment against the object of social condemnation'. One of the characteristics of 'true education contents' commonly seen on the Internet is that it shows a tendency to 'fragmentation'. True educational contents are short in length, and the contents are very local. This reflects the characteristics of a postmodern society where totality disappears and small stories are consumed. Second, the standard for dividing good and evil is extremely 'arbitrary'. Whereas the existing stories of rewarding virtue and punishing vice had universal values such as love, consideration, and peace, the content of true education distinguishes good and evil with an extremely narrow perspective. The way to justify arbitrary standard is to incite public outrage. Third, 'humour' is added. Here, humor is combined with the emotion of hatred, causing the problem of weakening people's critical consciousness.
