The purpose of this research is to define body characteristics of middle-aged men at ages between 35 and 55 whose physical changes are very prominent, by comparing the measurement data collected from this age group. This research also classifies different body types, and provides basic data for designing slacks' original forms according to each body type. Based on factor analysis of the measured data, seven key factors are grouped. And five different body types are classified based on the cluster analysis using factor marks. Type 1 refers to those who are tall and standard. This body type is characterized by trapezoid body shape when looked from the front, and slim abdomen when looked from the side. Type 2 refers to short and a little fat body shapes, with trapezoid front and protruding hip and abdomen. Type 3 refers to tall and fat body shapes, with rectangular front, protruding abdomen, and slim hip. Type 4 refers to those who are of medium height and a little obese, with rectangular front and protruding abdomen and hip. Type 5 refers to short and obese body shapes, with rectangular front, slim abdomen, and protruding hip. 12 items are available to judge middle-aged men's low body types and the hit ratio is 90%.

As the body shape change which occurs after middle age is the main factor affecting the fit of ready-to-wear clothes, this study was designed to classify and analyze the torso shapes of middle-aged men. This study sorted 3D body scans of 200 men aged 40-64 from the 8th Size Korea (2021) database and extracted their 47 measurement values using the Grasshopper algorithm for automatic extraction landmarks and measurements, developed by the previous research (Ryu & Song, 2022). Eight principal components (torso length, shoulder size, overall body size, abdomen prominence, back protrusion, neck inclination, upper body slope, and hip prominence) were identified and four torso shapes were classified. Shape 1 (28.5%) exhibited the shortest torso length, the narrowest shoulders, and the most protruding back. Shape 2 (21.0%) exhibited the skinniest body and the largest backward inclination of the upper body. Hence, the back appeared to be protruding, and the abdomen looked prominent. Shape 3 (25.5%) had the largest overall body size. Thus, the abdomen looked the least protruding, and it exhibited the flattest back. Shape 4 (25.0%) had the longest torso, widest shoulders, straightest neck, and the least protruding hips. This study suggested these three discriminant functions to identify a new person's torso type.

This study analyzes the velocity and pressure incurred by protruding shapes installed within the inlet part of a pressurized membrane module during operation to determine the fluid flow distribution. In this paper, to find the flow distribution within a module, it investigates the velocity and pressure values at cross-sectional and outlet planes, and 9 sections classified on outlet plane using computational fluid dynamics. From the Reynolds number (Re), the fluid flow was estimated to be turbulent when the Re exceeded 4,000. In the vertical cross-sectional plane, shape 4 and 6 (round-type protrusion) showed the relatively high velocity of 0.535 m/s and 0.558 m/s, respectively, indicating a uniform flow distribution. From the velocity and pressure at the outlet, shape 4 also displayed a relatively uniform fluid velocity and pressure, indicating that fluid from the inlet rapidly and uniformly reached the outlet, however, from detailed data of velocity, pressure and flowrate obtained from 9 sections at the outlet, shape 6 revealed the low standard deviations for each section. Therefore, shape 6 was deemed to induce the ideal flow, since it maintained a uniform pressure, velocity and flowrate distribution.

사면안정분야의 해석과 설계에는 한계평형법(LEM)과 전단강도 감소기법(SSR)이 주로 사용된다. 이 두 방법은 2차원과 3차원 해석을 모두 수행할 수 있지만 많은 연구자들에 의해 전단강도 감소기법이 해석 변수에 대해 더욱 민감하게 반응하고 합리적인 결과를 산출한다고 알려져있다. 그러나 전단강도 감소기법의 모델링의 복잡함과 해석시간의 증가 등의 이유로 현계평형법이 여전히 일반적으로 사용되고 있다. 본 연구에서는 FLAC 3D를 사용하여 전단강도 감소기법을 통한 돌출된 암반사면의 3차원 효과에 대해 연구하였다. 수치해석 변수는 사면의 경사, 높이, 지반강도, 사면의 돌출길이이며 연구 결과 사면의 안전율은 암반의 강도보다 사면의 형상에 더 영향을 받는 것으로 나타났다.

Purpose: Several studies of an endoscopic mucosal resection(EMR) have been reported, but reports about benign protruding lesions that arise at the scar of EMR for early gastric cancer (EGC) or a gastric adenoma are rare. The purpose of this study was to elucidate endoscopic and histological characteristics of benign protruding lesions which arise at the scar of an EMR for EGC and a gastric flat adenoma. Materials and Methods: In 101 lesions (73 gastric flat adenomas and 28 EGCs) from 96 patients, 16 lesions developed new protruding lesions that arose at the scar of the EMR. We retrospectively analyzed the endoscopic findings of initial and protruding lesions, and several other clinical factors (H. pylori infection, eradication therapy, and proton pump inhibitor (PPI) or H2-blocker use). Results: 1. The mean duration until detection of the protruding lesion was 8.9 months ($1.5\∼27$). Protruding lesions arose at the scar of the EMR in 1 of 28 EGCs ($3.6\%$) and from 15 of 73 gastric flat adenomas ($20.5\%$). All of the patients were men. 2. With respect to the endoscopic findings, the shapes of the protruding lesions were as follows: 10 Yamada (Y) I, 4 Y-II, 1 Y-III, and 1 flat lesion. Histological examination of the protruding lesions revealed regenerating hyperplasia in 5 lesions, intestinal metaplasia in 5, and both in 6. 3. The incidence of these lesions was higher in cases of tubular adenomas with focal high-grade dysplasia than in cases of tubular adenomas without dysplasia (p<0.05). 4. The incidence of H. pylori infection was higher in patients ($81.7\%$) who developed a protruding lesion than in those ($51.8\%$) who did not develop (p=0.029); also, the incidence of use of PPI was higher in those patients (p=0.045). However, eradication therapy for H. pylori and duration of use of PPI or H2-blocker showed no difference between groups. Conclusions: It may be possible that the potential hyperplasia that may reside in normal mucosa surrounding EGC or a gastric adenoma might awaken during the healing process of the EMR ulcer and develop to benign protruding lesions. And, H. pylori and PPI might also be related to the development of the protruding lesions.

Module coordination(分數), which is crucially relevant to plan shape of a fortress and the location of its gates and chis(雉, protruding posts), have not been thoroughly studied, despite its importance in fortress system. While plan shape of Goryeo fortress features orderly placement of gates and chis, under medium-sized J oseon fortress doesn't follow it strictly. As a result, fortresses with various plan shapes greatly outnumber those of Goryeo. Especially, Gimhaeeupseong Fortress, which is a large-scale town wall, shows such a complicated plan shape, making it difficult to figure out its modular coordination. Presumably, the reason for J oseon fortress' complicated plan shapes, which doesn't follow the orderly modular coordination, is thought to be in its various geographical conditions. Also, it seems that the building of fortress with such various and complicated plan shapes was to deter enemies from intruding by confusing them. And various plan shapes of fortress are also figured out to be pertinent to street system of towns and positions of public offices.

The purpose of this study is for size suitability and fitness improvement for Korean 20's women. This study has classified hip types of 20's women by the 6th Korean Anthropometric Survey(Size Korean), then compared their lower body-type by hip types each other. The results are as follows. Factor analysis in sorting hip types can be explained 77.72% by nine factors. And cluster analysis can be divided into three types. Type 1 is referred to as a general type which has the largest size in the 'Hip circumference', but the buttocks's horizontal sizes are in the middle size besides the hip line. Type 2 is referred to as a protruding type in upper buttocks which is large in protruding volume of upper buttocks, but the buttock's horizontal sizes are small including 'Hip circumference', and buttock's horizontal section form close to circle. Type 3 is referred to as a type which is contrary to Type 2. Type 3 is small in protruding volume of upper buttocks, but large in lower buttocks, and the protrusions in whole buttocks are small, so the side view of Type 3 made gentle fit shape. By these results, the study could classify lower body of 20's women, and it can be basic data for new sizing systems and pattern development of bottoms.

Photographic measurement was first made with the subjects of 190 males in their 20s residing in the Ningbo area, Zhejiang Province in China. In this second report, lower body shapes were classified and discriminated by using indirect measurement, measurement items, and lower body analysis. The following sums up the research: 1. The subjects were $8.85^{\circ}$ (hip breadth angle), $1.58^{\circ}$ (abdomen upper angle), $11.80^{\circ}$ (hip upper angle), and $5.12^{\circ}$ (lateral lower body posture angle). 2. The subjects of Chinese males in their 20s showed three types of lower bodies: Bow Legs & Slight Slant of Lateral Lower Body Type (30.5%)-gap between legs, curve waist-hip contour, average abdomen-hip profile, and lateral lower body posture were slightly slanted forward. Adjacent Straight Legs & Slight Slant of Lateral Lower Body Type (35.8%)-adjacent straight between legs, curve waist-hip contour, slim abdomen-hip profile, and lateral lower body posture were slightly slanted forward. Balance Legs & Large Slant of Lateral Lower Body Type (33.7%)-average between legs, straight waist-hip contour, protruding hip profile, and lateral lower body posture were largely slanted forward. 3. Eight useful variables for the categorization of the subjects' lower body types were chosen through stepwise discriminant analysis, and the hit ratio of discrimination was 97.9%.
