The purpose of this research is to develop the design, pattern and size system of brief as a measurement garment in order to obtain more precise silhouettes and sizes of the body in 3D measurements. The results of this research are as follows: First, nylon/lycra materials which elasticity is equivalent to 18%(wale) and 27%(course), were selected as a material for briefs to minimize possible error in measurement and deformation of body shape caused by looseness or tightness in its measured parts. And T-back style design was selected, of which briefs neither deform human body nor cause overlapping or excessive tightness when was put on the measurement garment over it. Second, different darts for men and women were adopted into the pattern in consideration for the shape of hip. Third, the waist band of briefs was located between the waistline and abdominal girth line so that it didn't interfere with measurement, and using a wide band of 40mm minimized the tightness of the human body. In addition, the stitch lines and sewing procedure were simplified to minimize the deformation of body shape resulting from inseams and stitch lines. Finally, for the size of briefs, 6 cm intervals were set on the basis of the waist girth and 8 kinds for men and 6 kinds for women were selected in descending order of appearance rate by the interval sections. English T meaning T-back design and numbers representing the waist girth were marked in parallel for the name of size.

To understand the shape of the neck in a view of garment planning, principal component analysis has been appliedto the measurement of the neck. The neck surface development and the cross sections of the neck have been observed. The materials consist of the body mearsurements, the neck surface developments and the cross sec- tions of the necks of a total of 108 korean woman students. The difference between the right side and the left side of the neck has not been reconginiged. But the differenece among the height of the front neck point, that of the side neck point and that of the back neck point has been recognized. 2. The initial 41 items have been found having variety and duplication. So two criteria have been made to solve those problems and the selection of 34 items have been made by each criterion. 3. 43 and 34 items have been compared by means of accumulative ratios of contribution and of clearness within the meaning of principal component. As a result, 34 measurement items have been further anylysis. 4. As a result of principal component analysis on the 34 items, the four principal components have been found obtaines and inter-preted. The four principal components are 1) the thick of the neck, 2) the front neck-line on the waist basic pattern, basic pattern, 3) the shape of the neck surface development, and 4) the back neck-line on the waist basic pattern. 5. According to the graphic informations concerning these principal components, the meaning of these four principal components has been grasped on the visual. As a result, there is a large individual difference in the shape of neck.

The aim of this study is to elucidate the effect of keratinase on epidermis of rat skin. Twenty-five male Sprague-Dolly rats were used. The hair on the back were removed and $2{\times}2cm$ area was marked. The rats were divided five groups; 1) Control group(Co), 2) Cleansing gel group(Cl), 3) Cleansing gel+keratinase group, 4) Exfoliant gel group(Ex), and 5) Exfoliant gel+ keratinase group(Ex+K). The solutions were applied to the back area twice a day for five days. On fifth day, the skins were harvested, fixed and prepared for histologic sections. The thickness of keratin layer, living epidermis, dermis, and cell layer number of living epidermis were measured. In the group containing keratinase(Cl+K, Ex+K), the thickness of keratin layer and living layer were thinner than other groups. However, there were no significant differences of the cell layer number of living epidermis and thickness of the dermis among the five groups. We think the keratinase may have the effect thinning the keratin layer as well as the thickness of living epidermis, without effecting the living cell and dermal component. The keratinase containing soap may be of benefit to remove the excess keratin layers in human.

The structural performance of cold-formed steel (CFS) built-up battened columns were numerically investigated in this paper. The built-up column sections were formed by connecting two-lipped channels back-to-back, with a regular spacing of battens plates, and have been investigated in the current study. Finite element models were validated with the test results reported by the authors in the companion paper. Using the validated models, the parametric study was extended, covering a wider range of overall slenderness to assess the accuracy of the current design rules in predicting the design strengths of the CFS built-up battened columns. The parameters viz., overall slenderness, different geometries, plate slenderness (b/t ratio) and yield stress were considered for this study. In total, a total of 228 finite element models were analyzed and the results obtained were compared with current design strength predicted by Effective Width Method of AISI Specifications (AISI S100:2016) and European specifications (EN1993-1-3:2006). The parametric study results indicated that the current design rules are limited in predicting the accuracy of the design strengths of CFS built-up battened columns. Therefore, a design equation was proposed for the AISI and EC3 specifications to predict the reliable design strength of the CFS Built-up battened columns and was also verified by the reliability analysis.

This paper proposes the speech and noise recognition system by using a neural network in order to detect the speech and noise sections at each frame. The proposed neural network consists of a layered neural network training by back-propagation algorithm. First, a power spectrum obtained by fast Fourier transform and linear predictive coefficients are used as the input to the neural network for each frame, then the neural network is trained using these power spectrum and linear predictive coefficients. Therefore, the proposed neural network can train using clean speech and noise. The performance of the proposed recognition system was evaluated based on the recognition rate using various speeches and white, printer, road, and car noises. In this experiment, the recognition rates were 92% or more for such speech and noise when training data and evaluation data were the different.

Gangwon Provincial Office, which is Historical Landmark No. 439, existed from 1395 to 1895. It played a significant role of provincial administration. Gangwon Provincial Office was rebuilt in the $17^{th}$ Century when governors' additional job system began. It had 50 buildings and 670 sections. During the Japanese colonial era and the Korean War, most of the buildings were demolished, and in 2005 partially restored. Currently, after the old Wonju City Post Office was demolished, the back garden facilities of the Provincial Office are being restored. The back garden of Gangwon Provincial Office was completely destroyed when the Japanese army base at Wonju made it a playing field during the Japanese colonial era. After demolishing the old post office in the back garden, excavation and investigation were made. A pond and building relics were found, but they were too damaged to be restored. However, this thesis found that there were Bongraekak, Yeongjusa(Kwanpungkak), Cheyako, Joojeong Rainbow Bridge after studying literature and paintings. There were also Hwansunjeong and Bangjangdae outside the pond. The names of the back garden and how they were made are related to hsien. In the pond, they made 3 islands signifying Mt. Samshin(immortal world) in the legend and built pavilions on that. The pavilions of the back garden were named Bongrae, Yeongju, and Bangjang, and the titles of other pavilions also had the names of hsien. The back garden of Gangwon Provincial Office was made like an immortal world, befitting its role of governing Mt. Bongrae(Mt. Geumgang.) The governors of Gangwon Province often went to the back garden and enjoyed becoming a hsien. They regarded themselves as the owners of Bongrae, i.e., the immortal world. Gangwon Provincial Office has a unique historical significance because it implemented an immortal world, making use of the characteristic of Gangwon Province.

A 52-year-old woman presented with lower back pain, progressive symmetrical paraparesis with sensory impairment, and sphincter disturbance. Magnetic resonance imaging (MRI) of the whole spine revealed multiple intradural extramedullary serpiginous-mass lesions in the subarachnoid space continuously from the prepontine to the anterior part of the medulla oblongata levels, C7, T2-T8, and T12 vertebral levels distally until the end of the theca sac and filling-in the right S1 neural foramen. Sparganosis was diagnosed by demonstration of the sparganum in histopathological sections of surgically resected tissues and also by the presence of serum IgG antibodies by ELISA. DNA was extracted from unstained tissue sections, and a partial fragment of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene was amplified using a primer set specific for Spirometra spp. cox1. After sequencing of the PCR-amplicon and alignment of the nucleotide sequence data, the causative agent was identified as the larva of Spirometra erinaceieuropaei.

Objectives To analyze the prognosis of patients with low back pain according to the severity of abnormal lumbar lordotic angle and Ferguson's angle. Methods Data from electronic medical record of a total of 199 patients hospitalized in Korean medicine hospital were analyzed. With the sagittal view of lumbar spine X-ray, lumbar lordotic angle was defined as the angle between the superior endplate of L1 with the inferior endplate of L5. Ferguson's angle was defined as the angle between the superior surfaces of the sacral with a horizontal line. 'Measure Cobb's Angle Tool' of 'INFINITT PACS' was used to measure both angles. Lumbar lordotic angle and Ferguson's angle were subdivided into five sections. The number of days from onset and the duration of hospitalization were analyzed in each section. Results Severe hypolordotic lumbar lordotic angle group were found to have longer medical history and hospitalization duration than the control group. The ratio of long-term hospitalization (over 15 days) and chronic medical history (over 180 days) of patients with severe hypolordotic Ferguson's angle were significantly higher than the control group. The ratio of patients with chronic medical history (over 180 days) was significantly higher in severe hyperlordotic Ferguson's angle group than the control group. Conclusions Severe hypolordotic lumbar lordotic angle was related to patient's prognosis. Both severe hyperlordotic and severe hypolordotic Ferguson's angle were found to be related to patient's prognosis. However, a moderate loss of lumbar lordotic angle and Ferguson's angle was not related to prognosis of low back pain patients.

Imcheong-gak[臨淸閣] was a familial residence constructed in the early half of the Joseon dynasty period. It was partially destroyed by a fire during the 1590s war[壬辰倭亂] with the Japanese, and another fire that was caused between 1631 and 1634. The inner chamber[An-chae] and the Sarang section[Sarang-chae] today is the result of a partial reconstruction that took place back in 1626 and again around 1634. The residence also went through some changes because the new Ondol[溫突] heating system had to be applied to the structure. Based upon sections that remain in their original forms, we can presume that the Imcheong-gak residence originally had an inner chamber which was composed of the following elements: A main structure which was built upon a foundation featuring a Matbae[맞배] roof, two "Ik'rang[翼廊, flank]" sections on the East and West sides of the inner chamber, and a "Haeng'rang[行廊, passage]" structure on the opposite side of the main structure. Unlike the main structure, other portions of the inner chamber were all built directly upon the ground, and showed multiple stories, with Matbae roofs of their own. We can also assume that the Sarang section in the south would have been a pre-Ondol[溫突] bedroom, with a Board platform[板房] and a Gomi-ceiling[Gomi-banza] fashion.

This study proposes medical gowns for interns and residents that address the functions of utility and activity. Based on the questionnaires, the prototype focused on the pockets for practical use and movement adaptability. Functional pockets were made by increasing pocket sizes and separating pockets with sections according to use. An inside pocket and a loop for an identification tag was placed on the chest pocket and the side seam pocket were oblique lined. To resolve horizontal stress on the back of the gown,6 cm action pleats were added at both ends of the bladebone. The elbow area was tucked up to improve the workplace activities. To reduce hamper on the gown hemline, slits were added along the gown side seam. The front button was changed into an inside button closure. The cuffs, belt, and back waist belt were removed due to occupational cases of inconvenience. The length of the sleeves was adjusted with belts to improve the movement of the arms. In accordance with design preference, the gown was designed to be knee-length with wrist length sleeves. Blue colored (2.5PB 3/12: by Munsell) material was inserted to reduce the contamination on the neck, cuffs, front closure, and hemline area. The planning cloth of the experimental gown was designed to improve activity function, cleaning, and comfort from light materials. The field test (with 30 doctors at university hospitals and the objective assessment with 9 subject groups)were done by the valuation between the existing gown and the prototype. The results showed that the prototype had to be modified by decreasing the pocket size, expanding the usage of the penholder, and simplify front pockets in order to maintain unity. The loop for the identification tag, inside pocket, and the blue colored material had to be removed. The front closure of the gown had to return to its original state.
