Recently, many New Han-oks have been constructing in all over the country to popularize as a type of green house. But, achievement of thermal performance of external wall is still the very important issue to become popular. Purpose: The purpose of this study is to verify the thermal performance level of modern New Han-ok through Temperature Difference Ratio inside(TDRi) analysis at corners of the external wall in Han-ok. Method: To achieve this goal, measurements were carried out in 12 Han-oks(experimental mock-up(1), exhibition Han-ok(1), happy village Han-oks(10)) by taking a infra-red thermography using thermal video system. Following are analysis items about connection joint between wall and wood columns of external wall conditions; the part between external wall and external wall(2D), external wall and ceiling(or floor)(2D), 2 external walls and ceiling(or floor)(3D) and so on. Result: It was analyzed that the probability of condensation at most of connection joint appear high and TDRi of 3D corners is higher than that of 2D corners in general. It means that the development of construction techniques about connection joint between wood columns and external wall is still required. The results of this study may be used to improve the construction technology of new Han-ok and as a basis for the specifying the desired thermal comfort environment of dwelling.

As multimedia applications become popular, computers increasingly require high-speed DSP for 3-DIM computer graphic. In this Paper, a Macro-cell Library of conditional select adder/subtracter is proposed for DSP within high speed and low power consumption. Using, this design method, we are able to obtain an auto generation of the adder or(and) subtracter from 8-bit to 64-bit. The proposed adder/subtracter has been fabricated with a 0.25${\mu}m$, single-poly, five-metal, N-well CMOS technology. From the experimental results, delay time is 3.43ns, and the power consumption is 42.8${\mu}w$/MHz at the input frequency of 50MHz, at 2.5V single power supply, in case of the 32-bit adder/subtracter.

Lumbopelvic stabilization exercise has become the most popular treatment method in lumbar rehabilitation since its effectiveness was shown in some aspects of pain and disability. The abdominal drawing-in maneuver (ADIM) has been extensively implemented to promote lumbopelvic stability. However, performing ADIM correctly is difficult even for healthy subjects, and it is time consuming to train people in ADIM. Thus, the purpose of this study was to compare abdominal muscle [rectus abdominalis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO)] activity during lumbopelvic stabilization exercises (ADIM only, ADIM with a ball, maximum exhalation only, and maximum exhalation with a ball) performed in a supine position with feet against a wall. Fifteen healthy subjects were recruited for this study. Surface electromyography was used to measure abdominal muscle activity during lumbopelvic stabilization exercises. A one-way repeated-measures analysis of variance was used to determine the statistical significance of RA, EO, and TrA/IO muscle activity during four lumbopelvic stabilization exercises. Both-side TrA/IO muscle activity was significantly greater with maximum exhalation with a ball than with ADIM only or ADIM with a ball (p<.008). The results of this study suggest that maximum exhalation with a ball can be used as an effective lumbopelvic stabilization exercise to increase TrA/IO muscle activity in healthy subjects.

This study is purposed to analyze the characteristics of different images of Hollywood movie costumes centering on the costumes of actresses who are the fashion leaders creating fashions especially focusing on those in 1930s. The scope of this study covers the movie costumes selected from the movies ranging from 1930 to 1939 centering on the Hollywood movies produced and released by large movie distributors and the movie costumes of heroins that exerted great influences on the culture and clothing history of 1930s were examined. As for the methods of study, visual data and image data including movies were collected through related dissertations, articles in journals, internet sites relating to movies and photos and we have analyzed each of the characteristics of the movie costumes appearing in each image. The result of this study is as follows. Firstly, ethnic images were the reflection of orientalism that was popular in the fashion of the age with the purpose of highlighting the exotic appearances of the actresses and were the cases where the characters of the actresses had to be expressed in ethnic styles due to the spatial backgrounds of movie works. Secondly, glamorous images were highlighting the appeals of plump breasts, shoulder lines and the bodies constricted in the middle and the Hollywood movie costumes in 1930s. The smooth and flowing silhouettes of the heroins of the age were mainly long and slim patterns and female's images were expressed by highlighting the beauty of leg lines or especially by halter neck evening dresses that exposed backs and covered breasts. Thirdly, mannish images reflected tough images of males in order to further highlight the reality of the characters of the heroins of the age pursuant to the emergence of the opinions advocating the equality between men and women.

This study examines plant patterns expressed on the fabrics during the Goryeo Dynasty and many countries in the Chinese continent and analyzes their symbolism and formativeness. This study deals with clothes which is one of the most fundamental aspects in a culture and plant patterns on them; it examines the overall formativeness of plant patterns in East Asia from the 10th century to the 14th century by studying plant patterns in the Goryeo Dynasty and the contemporaneous dynasties in the Chinese continent - Five Dynasties, Song Dynasty, Western Xia Dynasty, Liao Dynasty, Jin Dynasty and Yuan Dynasty. The plant patterns of each country were categorized by the type of plant. The composition and expression of plant patterns were examined and statistically analyzed. Small flowers were found in Goryeo fabrics twice more than other types that could be clearly identified, and peony was the most popular flower used in Chinese fabrics. In terms of composition of plant patterns, both Goryeo and Chinese fabrics had plant only patterns more frequently than the patterns mixed with animals or jewels. Regarding expression methods of plant patterns, the most common one in Goryeo fabrics was the petal-type, while the branch-type is the most common one in Chinese fabrics. The plant patterns of the Goryeo Dynasty show beauty of simplicity with minimalism and simplification while expressed with brilliant sold threads on dark background, such as purple or light green, so the overall feeling of fabrics was simple yet nobel.

Reed-Solomon(RS) codes have been employed to correct burst errors in applications such as CD-ROM, HDTV, ATM and digital VCRs. For the decoding RS codes, the Berlekamp-Massey algorithm, Euclidean algorithm and modified Euclidean algorithm(MEA) have been developed among which the MEA becomes the most popular decoding scheme. We propose an efficient recursive cell architecture suitable for the MEA. The advantages of the proposed scheme are twofold. First, The proposed architecture uses about 25% less clock cycles required in the MEA operation than[1]. Second, the number of recursive MEA cells can be reduced, when the number of clock cycles spent in the MEA operation is larger than code word length n. thereby buffer requirement for the received words can be reduced. For demonstration, the MEA circurity for (128,124) RS code have been described and the MEA operation is verified through VHDL.

Response of reinforced concrete (RC) column-bent piers subjected to bidirectional seismic loadings was experimentally investigated. RC column-bent piers represent one of the most popular shapes of piers used in Korea highway bridges. Four column-bent piers were constructed in 400 mm diameter and 2,000 mm height. Each pier has two circular supporting columns. These piers were tested under bidirectional lateral load reversals with an axial load of $0.1f_{ck}A_g$. The test parameters included : different transverse reinforcement contents and lap-spliced longitudinal reinforcing steels. Test results indicate that the lap splice of longitudinal reinforcing steels have significantly influenced on hysteretic response of column-bent piers similar to previous test results for single columns with corresponding test parameters. Column capacity was changed with the level of transverse confinement. From the comparison of test result for single column under unidirectional loading, the damage of single column was concentrated on lower plastic hinge region but the damage of column-bent piers was scattered to upper and lower plastic hinge region.

We have attempted to give some physical into the factors that control the response of subsurface target to plane wave excitation at VLF (very low frequency) frequencies. Although the VLF technique has some serious disadvantages, such as a lack of penetration depth and limited frequencies, its advantages are also extremely important to have made it by far the most popular electromagnetic technique in current use. In the magnetic-field measurement mode these lightweight, relatively low-priced tools allow us to survey large areas rapidly and inexpensively, to locate and roughly define subsurface electrical conductors. When used in the electric-field mode the technique is, in simple environments, capable of quantitative interpretation and once again the speed and relative cheapness of these devices makes them a natural 'first electromagnetic tool ' to use in reconnaissance mapping.

Purpose: The purpose of this study was to identify the trends in studies published in Journal of Korean Critical Care Nursing (JKCCN) from 2008 to 2013. Methods: A total of 65 studies published between 2008 to 2013 were reviewed using criteria developed by researchers. Results: Approximately 36% of studies were conducted with patients. Intensive care unit (ICU) was the most popular site as the study setting. Among 59 research papers, 42.4% were approved by institutional review board (IRB). Quantitative studies were 78.6%, while qualitative studies were 4.6%. The research designs for the quantitative studies were survey (52.3%), quasi-experimental (16.9%), and so on. There was no randomized controlled trial. The most frequently used methods to provide nursing intervention was education. In addition, "nurse" and "ICU" were most commonly used keyword. Conclusion: Considering the low rate of IRB approval, more stringent application of research ethics is necessary to improve the quality of JKCCN. In addition, more randomized controlled trials should be encouraged to support evidence-based practice in critical care.

Objective : Gagamchongmyung-tang is clinically one of the most popular prescriptions as an herbal medicine for the treatment of amnesia. In order to evaluate its neuroprotective effects on the ischemia-induced cognitive deficits caused by middle cerebral artery occlusion (MCAO), we examined its ability to reduce impairments of learning and memory of rats in the Morris water maze. Method and Result : Focal cerebral ischemia produced a decrease in acetylcholine transmission in the hippocampus, and deficits of learning and memory in the Morris water maze task. Treatment with two types of Gagamchongmyung-tang, methanol and water extracts, produced a substantial increase in acquisition in the Morris water maze. Treatment with methanol extract of Gagamchongmyung-tang increased the performance of the retention test in the Morris water maze. Consistent with behavioral data, immunohistochemical data showed that treatment with methanol extract, but not water extract, of Gagamchongmyung-tang significantly recovered reduction of AchE and ChAT reactivity in the hippocampal CAl area. Conclusion : These results demonstrated that methanol extract of Gagamchongmyung-tang has protective effects against ischemia-induced learning and memory impairments, and provided evidence of methanol extract of Gagamchongmyung-tang as a putative treatment for amnesia, vascular dementia, and longer memory.
