Objectives: The purpose of this study was to determine the relationship between conscious sedation, a moderate sedation method used to reduce dental fear, and anxiety. Methods: The previously developed modified dental anxiety investigation scale (MDAS) and dental fear investigation scale (DFS) were investigated using a self-administered survey for adults aged 19 to 65 years old who visited a dental clinic located in Daegu City from April to November 2020. Those who met the ASA Recommendation Level 1 to 2 were the subjects of this study. The participants were evaluated using the sedation severity rating scale (OAA/S) during the implementation of conscious sedation. A lot of 106 valid questionnaires were analyzed using SPSS. Results: Dental fear and anxiety decreased significantly after dental care with conscious sedation. Dental fear after dental care accompanied by conscious sedation was statistically significant in females, those under the age of 40, those with a bachelor's degree or higher, and those who weighed 60 kg or less. Conclusions: Dental care using conscious sedation was found to have an effect on the reduction of dental fear after the dental procedure. Dental fear can occur in people of all ages, and, regardless of the individual's general and physical characteristics, conscious calming is considered an effective intervention for dental fear in all adults.

Purpose: Postoperative nausea and vomiting(PONV) is a common problem after general anesthesia. The aim of this prospective, double-blind randomized study was to compare the effect of Propofol-Remifentanil vs. Sevoflurane inhalational anesthetics on PONV after laparoscopic cholecystectomy. Methods: Forty patients (ASA physical status 1, 2) scheduled for elective surgery participated in the study. Twenty of them received total intravenous anesthesia (TIVA group) with Propofol-Remifentanil, and the rest were given Sevoflurane inhalational anesthetics (inhalation group). The TIVA group was induced with Propofol 5mcg/ml and Remifentanil 3~4mcg/ml. The anesthesia was maintained with the continuous infusion of Propofol 2~3mcg/ml and Remifentanil 2~3mcg/ml IV. The inhalation group was induced with Pentotal Sodium 5mg/kg and 3~4mcg/kg/hr IV Remifentanil. Maintenance was obtained with 1.5~2.0 vol% Sevoflurane. Results: The subjects in TIVA group reported less PONV than those in Sevoflurane inhalation anesthesia group. Conclusion: Propofol-Remifentanil anesthesia (TIVA group) was considered a satisfactory anesthetic technique in reducing PONV in patients with laparoscopic cholecystectomy.

The purpose of this study was to investigate the housewives’ consumption pattern and preference of the Korean rice cake asa substitute for meal. The rate of housewives who had eaten rice cake as a substitute for meal were 75.30% and those who had not were 20.83%. Usually 62.03% of them ate rice cake for breakfast, and 34.21% did them within one time per a week. Reasons for eating rice cake for meal were investigated on ‘easy to eat(54.51%)’, ‘good taste (24.44%)’ and ‘healthy food(14.29%)’. The older housewives wanted healthy rice cake for meal and ate with tea and Kimchi(Dongchimi). The younger ones ate rice cake for meal with tea and milk. Thawing methods of frozen rice cake for meal were different between the older and the younger, respectively, steaming and using microwave. Kinds of rice cake as a substitute meal were Injeolmi(50.75%), Backsulgi(49.62%), Chaltteok (47.74%) and Yaksik(46.44).

경희대학교 치과대학병원 소아치과에 내원한 환자 중, negative이거나 definitively negative로 분류되는, 전신적으로 건강한(ASA I) 4세미만의 아동 20명(평균 30.8개월, 남아 12명, 여아 8명)을 대상으로 하여, 두 차례의 진료를 시행하였다. 첫 진료시 chloral hydrate(50mg/kg)와 hydroxyzine HCl(25mg)만을 경구투여하고, 동일한 대상에게 두 번째 진료시 chloral hydrate (50mg/kg)와 hydroxyzine HCl(25mg)의 경구투여와 함께 $N_2O-O_2$를 병용하여 통상의 보존적 처치를 시행하였다. 각 치료과정 별로 나타나는 진정효과를 Houpt의 평가표(수면, 울음, 움직임, 전반적 행동지수)에 의해 측정하였고, pulse oximeter를 이용하여 맥박수 및 동맥혈 산소포화도의 차이 등을 비교, 평가하여 그 결과 chloral hydrate와 hydroxyzine HCl의 경구투여와 함께 $N_2O-O_2$를 병용한 경우가 chloral hydrate와 hydroxyzine만을 경구투여한 경우에 비해 어린이의 행동조절에 더 바람직한 진정요법인 것으로 판단된다.

Background: Recently postoperative pain control with continuous epidural analgesia has been increased. This study aimes to evaluate backpain following continuous epidural analgesia by pressure threshold meter (algometer). Methods: After informed consent, 50 ASA physical status I or II patients undergoing elective gynecologic surgery were selected. After placing epidural catheter, patients received morphine 0.05mg/kg with 0.25% bupivacaine 5 ml followed by continuous infusion of 0.125% bupivacaine 100 ml with morphine 4 mg for 48 hours. backpain was measured by pressure algometer over lumbar paraspinalis at the L4 level, 5 and 7 cm from the midline on preoperative, operation day, 1st, 2nd, 3rd, and 4th postoperative days. Results: Postoperative mean pressure thresholds of were higher than preoperative value (p<0.05). Conclusion: The continuous epidural analgesia dose not provide or aggravate postoperative backpain, but it must be evaluated for long term follow-up.

Background: Myprodol, a newly introduced combination analgesics with codeine, ibuprofen and paracetamol was evaluated in the dental surgery patients for its efficacy and side effects. Methods: Total 60 ASA I or II outpatients dental surgical patients were randomly assigned into three groups(n=20 each). After various oral procedures, one of three oral analgesics, myprodol, ibuprofen or codeine, was prescribed to each patients in double blind fashion for three days. Each patient was followed carefully by daily phone calls for verbal analog pain scale, side effects and patient's satisfaction level. Results: Demographic data and duration of surgery revealed no statistical differences in all three groups. Myprodol group showed better verbal analgesic scores consistently for the study period than ibuprofen or codeine group. Adverse effects were minimal. Patients' satisfaction level was high in all three groups. Conclusion: We conclude that myprodol is an excellent oral analgesic for day-surgery based dental procedure patients. This effect appears to be synergistic among different analgesics rather than additive.

In this paper, new index was developed to estimate the depth of anesthesia during general anesthesia using EEG. Analysis of the power spectral density(PSD) of EEG was used to develop new parameters because EEG signal tends to have slow wave during anesthesia. Classifier for index creator was developed by using SEF, BDR and BTR parameters, which are calculated by power spectral density. EEG data were obtained from 7 patients (ASA I, II) during general anesthesia with Sevoflurane. The anesthetic depth evaluation indexes ranged from 0 to 100. The average were $86.05{\pm}10.1$, $36.98{\pm}20.2$, $15.33{\pm}13.6$, $50.87{\pm}16.5$ and $87.72{\pm}11.7$ for the states of pre-operation, induction of anesthesia, operation, awaked and post-operation, respectively. The results show that while the depth of anesthesia was evaluated, more accurate information can be provided for anesthetician.

a-Si 박막 태양전지는 a-Si:H을 유리 기판 사이에 주입해 만드는 태양전지로, 뛰어난 적용성과 경제성을 지녔으나 c-Si 태양전지에 비해 낮은 변환 효율을 보이는 단점이 있다. 변환 효율을 높이기 위한 연구 방법으로는 a-Si 박막 태양전지 단일cell 제작 시 high Bandgap을 가지는 p-layer를 사용함으로 높은 Voc와 Jsc의 향상에 기여할 수 있는데, 이 때 p-layer의 defect 증가와 activation energy 증가도 동시에 일어나 변환 효율의 증가폭을 감소시킨다. 이를 보완하기 위해 본 실험에서는 p-layer에 기존의 p-a-Si:H를 사용함과 동시에 high Bandgap의 buffer layer를 p-layer와 i-layer 사이에 삽입함으로써 그 장점을 유지하고 높은 defect과 낮은 activation energy의 영향을 최소화하였다. ASA 시뮬레이션을 통해 a-Si:H보다 high Bandgap을 가지는 a-SiOx 박막을 사용하여 p-type buffer layer의 두께를 2nm, Bandgap 2.0eV, activation energy를 0.55eV로 설정하고, i-type buffer layer의 두께를 2nm, Bandgap 1.8eV로 설정하여 삽입하였을 때 박막 태양전지의 변환 효율 10.74%를 달성할 수 있었다. (Voc=904mV, Jsc=$17.48mA/cm^2$, FF=67.97).
