Purpose: During Postpartum period many women complain multiple pain, cold hypersensitivity, hot flush, sweating and so on. We call the postpartum disease as San Hu Pung. We studied characters of DITI Characters of women suffering from Postpartum disease. Methods: We studied 55 patients visiting OOhospital from February 2006 to November 2007. The subjects were categorized in two groups, symptom group(37) and no symptom group(18). We measured the temperatures of abdomen(CV17, CV12, CV4), upper and lower limb(PC8, LU4, LR3, ST32) and back(GB21, BL18, BL53). We studied the difference of DITI between two groups by Student T-test using SPSS for windows (version 12.0). Results: The general characteristics such as age, days of postpartum, primiparity, cesarean section, partum season, breast-feeding of two groups were not different statistically. Temperatures of abdomen(CV17, CV12, CV4) and back(GB21, BL18, BL53) of two groups were not different statistically. Temperatures of Lt. PC8 and both LR3 of symptom group were statistically higher than no symptom group. The difference between Lt. PC8 and LU4, both LR3 and ST32 of symptom group were statistically higher than no symptom group. Conclusion: The results suggest that women suffering from Postpartum disease shows high temperature on hand and foot. It seems that postpartum disease patients tend to have blood deficiency. DITI can be useful to diagnose San Hu Pung. The more studies to diagnose San Hu Pung would be needed.

Purpose: To analyze risk factors and various nutrients associated with stunting among children aged 6-60 months. Methods: This is a case-control and cross-sectional study between 40 stunting cases and 40 controls. Data on possible risk factors associated with stunting were obtained through direct interviews and using a questionnaire. Examination of vitamin D, zinc, albumin, and ferritin levels was performed on both groups. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (IBM Co., Armonk, NY, USA) to determine risk factors for stunting and to assess the relationship between nutritional levels and stunting. Results: The incidence of stunting was highest in children aged 12-36 months. Children with low weight and very low weight for age comprised of 55% and 22.5%, respectively, of the study participants. The highest mother's educational level was junior high school (40%). History of low birth weight (LBW) was more commonly observed in the stunting group than that in the control group (25.0% and 7.5%, respectively; p=0.034, odds ratio, 0.310 [95% confidence interval, 0.122-0.789]). Approximately 7.5% of cases had premature birth. Exclusive breast feeding was found to be not correlated with stunting. The mean zinc level in the stunting group was 34.17 ng/mL, which was different from that in the control group (50.83 ng/mL) (p=0.023). Blood ferritin, vitamin D, albumin, and calcium levels were not strongly correlated with stunting. Conclusion: LBW is the main risk factor contributing to stunting and is strongly associated with low zinc level.

Google Earth enables people to easily find information linked to geographical locations. Google Earth consists of a collection of zoomable satellite images laid over a 3-D Earth model and any geographically referenced information can be uploaded to the Web and then downloaded directly into Google Earth. This can be achieved by encoding in Google's open file format, KML (Keyhole Markup Language), where it is visible as a new layer superimposed on the satellite images. We used KML to create and share fine resolution gridded temperature data projected to 3 climatological normal years between 2011-2100 to visualize the site-specific warming and the resultant earlier blooming of spring flowers over the Korean Peninsula. Gridded temperature and phonology data were initially prepared in ArcGIS GRID format and converted to image files (.png), which can be loaded as new layers on Google Earth. We used a high resolution LCD monitor with a 2,560 by 1,600 resolution driven by a dual link DVI card to facilitate visual effects during the demonstration.

This paper proposes a technique for improving IEEE 802.11e EDCA's performance by dynamically adjusting each class's contention window size based on each class's traffic amount. For providing differentiated service differently from 802.11, 802.11e EDCA maintains four classes each of which specifies different static minimum and maximum contention window sizes. Since the initial window sites significantly affect the 802.11e performance, several window adjustment schemes have been proposed. One of the schemes known as CWminAS (CWmin Adaptation Scheme) dynamically and synchronously determines the four windows' site based on the periodically measured collision rate. This method, however, can lower the send probability of high priority classes since it can't differentiate their collisions from those of low priority classes, leading to the channel underutilization. For solving this problem, we propose ACATICT(Adaptive Contention-window Adjustment Technique based on Individual Class Traffic) algorithm which adapts each class window size based on each individual collision rate rather than one average collision rate. Our simulation experiments show that ACATICT achieves better utilization by around 10% at maximum.

This study was a descriptive research that attempted to provide the basis for improving cultural competence by identifying the effect of multicultural awareness and cultural empathy on the cultural competence of nursing students. The subjects were nursing students from grades 1 to 4 who were enrolled in two nursing colleges in Gwangju and Chonnam. The data were collected from September to December 2018. The 201 data collected were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS 25.0 for windows. Multicultural awareness(r=.451, p<.01) and cultural empathy(r=.582, p<.01) had high positive correlations with cultural competence. The factors that affected the cultural competence were cultural empathy(β=.422, p<.001) and multicultural awareness(β=.222, p<.001) order. The explanatory power of these factors was 40.5%. These findings suggest that in order to promote the cultural competence of nursing students, strategies to promote multicultural awareness and cultural empathy should be developed, and these strategies should focus more on cultural empathy than on multicultural awareness.

Since 1970, MRI has greatly been developing in terms of strength of magnetic field, the number of receipt channels, and short time of examination. With the development of digital systems and wireless network, hospitals have also acquired, saved, and managed digital images taken by various kinds of medical imaging equipment. However, domestic universities fail to provide practice training course independently thanks to expensive practice equipment and high maintenance cost, and rely on clinical training. Therefore, this study developed a MR patient diagnosis program based on Windows PC to help out students before their working in clinical filed. The designed Relational Database of MRI Simulator is made up of seven tables according to functions and data characteristics. Regarding the designed patient information, each stepwise function was classified by the patient registration method in clinical field. In addition, on the assumption of the basic information for diagnosis, each setting and content were classified. The menu by execution step was arrayed on the left side for easy view. For patient registration, a patient's name, gender, unique ID, birth date, weight, and other types of basic information were entered, and the patient's posture and diagnosis direction were set up. In addition, the body regions for diagnosis and Pulse Sequence were listed for selection. Also, Protocol name and other additional factors were allowed to be entered. The final window was designed to check diagnosis images, patient information, and diagnosis conditions. By learning how to enter patient information and change diagnosis conditions in this program, users will be able to understand more theories and terms learned in practice and thereby to shorten their learning time in actual clinical work.

The Solar Energy R&D Department of KIER under the auspice of the Korean government is pushing hard on the development of the passive solar technology with high priority for the expeditious widespread use of solar energy in Korea, since the past few years of experiences told us that the active solar technology is not yet ready for massive commercialization in Korea. KIER has completed the construction of the Solar Energy Research & Test Center in Seoul, which houses the major facilities for its all solar test programs. The Center was designed as a passive solar building with great emphasis on the energy conserving ideas. The Center is not only the largest passive building in Korea, but also the exhibit center for the effective demonstration of the passive heating and cooling technology to the Korean public. The Center was designed to satisfy the requirements based on the technical and economical criteria set by the KIER. Careful considerations, therefore, were given in depth in the following areas to meet the requirements. 1) Passive Heating Concepts The Center employed the combination of direct and indirect gain system. The shape of the Center is Balcomb House style, and it included a large built-in sunspace in front. A partition, consists of transparent and translucent glazings, separates the sunspace and the living space. Since most activities in the Center occur during the day time, direct utilization of the solar energy by the living spaces was emphasized with the limited energy storage capacity. 2) Passive Cooling Concepts(for Summer) Natural ventilation concept was utilized throughout the building. In the direct gain portion of the system, the front glazing can be openable during the cooling season. Natural convection scheme was also applied to the front sunspace for the Summer cooling. Reflective surfaces and curtains were utilized wherever needed. 3) Auxiliary Heat ing and Cooling System As an auxiliary cooling system, mechanical means(forced convection system) were adopted. Therefore forced air heating system was also used to match the duct work requirements of the auxiliary cool ing system. 4) Effect ive Insulation & Others These included the double glazed windows, the double entry doors, the night glazing insulation, the front glazing-frame insulation as well as the building skin insulation. All locally available construction materials were used, and natural lightings were provided as much as possible. The expected annual energy savings (compared to the non-insulated conventional building)of the Center was estimated to be about 80%, which accounts for both the energy conservation and the solar energy source. The Center is being instumented for the actual performance tests. The experimental results of the simplified tests are discussed in this paper.

The eyes, the saying goes, are the windows of the soul. It's the first thing you notice about a person. Therefore, many people want to possess beautiful eyelids. Surgical formation of a palpebral fold and sulcus divides the lid into two well-defined segments (palpebral and pretarsal), producing the double eyelid desired by many Oriental women as well as an increasing number of man recently. Upper lid blepharoplasty is the Oriental eye is one of the variations of standard upper lid blepharoplasty. In Oriental double eyelid surgery, there have been two approaches to form a superior palpebral fold: the buried suture(nonincision) method and the full external incision method. Conventionally, the nonincision technique has been shown to produce little postoperative edema. However, the probability of the fold disappearing is high, and this technique cannot be performed in patients with fatty eyelids. Conversely, the incision technique has contrary characteristics. Recently, partial incision(or semi-open) technique which is combination of mentioned methods is used, this technique is removal of pretarsal tissue, muscle, and/or orbital fat around 2 or 3 incision site to facilitate tarsus-dermal adhesion. Our method is on the basis of this technique, furthermore, compared with conventional semi-open method, Y(Yang's) needle assisted double eyelid operation is more easy, convenient, saving-time method and provide satisfactory results.
