Objective : This study was conducted to examine self-selected goals and the outcome measures used in the Cognitive Orientation to daily Occupational Performance (CO-OP) approach for Developmental Coordination Disorder. Methods : Studies published from January 2012 to October 2022 in the PubMed, Embase, ScienceDirect, Cochrance Library databases were searched. Keywords used for search were ('developmental coordination disorder' OR 'DCD') AND ('Cognitive Orientation to daily Occupational Performance' OR 'Cognitive Orientation to Occupational Performance' OR 'CO-OP'). Among 211 searched studies, 7 selected studies that match the thesis of this study were analyzed. Results : The selected studies showed a relatively high level of evidence overall, including two randomized experimental studies, one non-random two-group study, three non-random one-group studies, one single-subject study. The self-selected goals preference of the children was high in the order of play, education, and daily life activities. Most of applicable sessions were conducted 10 times during a 1-h period, and intervention effects showed positive outcomes on the occupation performance motor domain. To measure the effectiveness of CO-OP, the improvement of occupational performance was evaluated using Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS), and the improvement of motor skills was evaluated using Movement Assessment Battery for Children (M-ABC). Conclusion : This study is expected to be used as basic clinical data when applying the CO-OP approach to Developmental Coordination Disorder.

If complete coronary artery occlusion occurs due to severer coronary spasm, malignant arrhythmias can lead to death. Therefore, early screening for coronary artery spasm angina is essential. Among the test methods, the drug injection test through coronary angiography is generally performed. Therefore, the purpose of this study was to evaluate the advantages of ergonovine drug test for vasospasitc angina examination during coronary angiography, such as the relationship between the procedure time, contrast medium usage, and radiation exposure effects of coronary angiography. Follow-up data of 142 patients who underwent coronary angiography and variant angina examination from september 2021 to february 2023 were used. As a result of analyzing contrast usage dose and dose area product and air kerma dose and number of imaging series and procedure time, variant angina examination was statistically significantly higher than coronary angiography. (p<0.001) In conclusion, variant angina examination other than coronary artery angiography are radiologically negative. Therefore, we think it is better to avoid excessive inspection. Nevertheless, in the case of the provocation test, the longer the examination time, the higher the fluoroscopy time and the amount of contrast medium used, so it is better to conduct the test as quickly as possible or shorten it.

Purpose: The aim of this study was to evaluate the shortterm outcome of a pylorus-preserving proximal gastrectomy by comparing it with a jejunal interposition after a total gastrectomy in proximal gastric adenocarcinoma. Materials and Methods: For 22 patients (12 men and 10 women) who underwent a pylorus-preserving proximal gastrectomy, several clinical parameters were obtained from the medical records retrospectively. In this study, the data were collected between September 1993 and December 1999 at Chungnam National University Hospital, and the results were compared with those of 25 patients (17 men and 8 women) who underwent an isoperistaltic simple jejunal interposition. Results: The average operative time in the pylorus-preserving proximal gastrectomy group (220 minutes) was shorter than that in the jejunal interposition group (243 minutes) (P<0.05). The hemoglobin and hematocrit levels were significantly higher in the pylorus-preserving proximal gastrectomy group at 2 years after the operation. The body weight ratio (postoperative body weight/preoparative body weight) in patients who had a pylorus-preserving proximal gastrectomy was significantly higher than that in patients with a jejunal interposition at 2 years after the operation. The jejunal interposition procedure had better outcomes in anastomotic site stricture, duration of hospital stay, and number of removed lymph nodes (P<0.05). Conclusions: We think that from the viewpoint of quality of life, a pylorus-preserving proximal gastrectomy, as well as a jejunal interposition, is a useful reconstruction method for early adenocarcinomas of the proximal stomach. However, stricture of the esophagogastrostomy site in the pyloruspreserving proximal gastrectomy is a common problem to be solved in the future.

Purpose: Aplasia cutis congenita (ACC) is a rare condition characterized by a localized absence of skin, and it can be associated with other congenital anomalies. This study was done to evaluate clinical course and outcome of ACC in neonates. Methods: Based on the medical records, we retrospectively reviewed 8 neonates diagnosed with ACC at Cheil General Hospital and Women's Health Care Center, Kwandong university College of Medicine from January 2004 to December 2010. We classified ACC by Frieden's classification and analyzed the patient's demographic data, clinical course and outcome. Results: Among 8 patients with ACC, 5 patients were classified to group 1; scalp ACC without anomalies and 3 patients to group 7; ACC localized to extremities without blistering. Defect size was from 0.3 cm to 1.5 cm, limited in the superficial skin or subcutaneous tissue without associated anomalies. Defects were healed under conservative treatment with mild scar formation within four months. Conclusion: ACC could be diagnosed easily through physical examination in neonates. All cases showed good clinical outcome without surgical treatment. However because of small numbers and small sized defects of cases, further study including lesions of large size is needed.

Purpose: This study was designed to compare the amount of polymerization shrinkage of dual-cure resin cements according to different polymerization modes and to determine the effect of light activation on the degree of polymerization. Materials and methods: Four kinds of dual-cure resin cements were investigated: Smartcem 2, Panavia F 2.0, Clearfil SA Luting and Zirconite. Each material was tested in three different polymerization modes: self-polymerization only, immediate light polymerization and 5 minutes-delayed light polymerization. The time-dependent polymerization shrinkage-strain was evaluated for 30 minutes by Bonded-disk method at $37^{\circ}C$. Five recordings of each material with three different modes were taken. Data were analyzed using one-way ANOVA and multiple comparison Scheffe′test (${\alpha}$=.05). Results: All materials, except Panavia F 2.0, exhibited the highest polymerization shrinkage-strain through delayed light-activated polymerization. No significant difference between light activation modes was found with Panavia F 2.0. All materials exhibited more than 90% of polymerization rate in the immediate or delayed light activated group within 10 minutes. Conclusion: As a clinical implication of this study, the application of delayed light activation mode to dual-cure resin cements is advantageous in terms of degree of polymerization.

The cone beam computed tomography(CBCT) which can acquire 3-dimensions images is widely used for confirmation of patient position before radiation therapy. In this study, through the simulation using the Monte Carlo technique, we will analyze the exposure dose by cone beam computed tomography and present the standardized data. For the experiment, MCNPX(ver. 2.5.0) was used and the photon beam spectrum was analyzed after Cone beam was simulated. As a result of analyzing the photon beam spectrum, the average energy ranged from 25.7 to 37.6 keV at the tube voltage of 80 ~ 120 kVp and the characteristic X-ray energy was 9, 60, 68 and 70 keV. As a result of using the water phantom, the percentage depth dose was measured, and the maximum dose appeared on the surface and decreased with depth. The absorbed dose also decreased as the depth increased. The absorbed dose of the whole phantom was 9.7 ~ 18.7 mGy. This is a dose which accounts for 0.2% of about 10 Gy, which is generally used for radiation therapy per week, which is not expected to have a significant effect on the treatment effect. However, it should not be overlooked even if it is small compared with prescription dose.

The purpose of this study was to reveal association between internal marketing and customer orientation. Internal marketing was composed of empowerment, educational training, reward system, internal communication and management support. We thought these factors affect to the consumer orientation. For this study, 191 dental hygienists in Busan, Ulsan and Kyungnam are participated in this study. The data were analyzed with descriptive statistics, t-test, ANOVA, pearson's correlation coefficients, and stepwise multiple regression analysis with SPSS 18.0 program. In conclusion, we obtained the next results. First, the mean of internal marketing behavior was 3.22 out of 5. In terms of sub-domain, educational training (3.88) is the highest, followed by empowerment (3.35), internal communication (3.10), management support (3.05) and reward system (2.79). Second, the internal marketing factors of internal communication, reward system orientation, management support, empowerment, and educational training had positive correlations with customer orientation (r=0.189~0.381). Third, the influencing factor in customer orientation were educational training (${\beta}=0.277$) and empowerment (${\beta}=0.276$), adjusted $R^2=0.202$. As dental patients' desire to medical service quality becomes diversified, the analysis result is considered to help the future dental service management.

Objectives : 'First-night effect' has been a well-known concept since 1960's. It is important because it is one of the major factors to be considered in assessing the reliability of polysomnographic data. However, 'reverse first-night effect' has also been described, resulting in the inconsistency of conceptualization. We attempted to investigate on the first-night effect in adults by having each of them take two nights of polysomnography in a controlled environment. Young healthy adult volunteers were chosen as subjects in order to rule out age- or health-related confounders. Methods : Polysomnography was performed on eight male medical students (mean $age=23.5\;{\pm}\;0.9$) for two nights with Grass model 78 polysomnograph. We scored manually under the standard protocol each epoch of the sleep records. Sleep variables were obtained and compared between the two nights. Results : Sleep period time(SPT) and total sleep time(TST) of the third fraction of night were significantly longer on the first night than on the second night (p<0.05). However, other sleep variables such as percentage of each sleep stage, sleep latency, REM sleep latency, number of waking, and sleep efficiency were not different between the two nights. Conclusion : We could not confirm the existence of first-night effect in this study. In healthy young male adults, it may not happen at all or may happen to a very negligible degree. Young healthy adults may have more adaptability to a new sleep environment. Also, the provision of a reasonably comfortable sleep environment could have helped them with abolition of first-night effect.
