Women in their 50s undergo significant changes to their bodies, including weight gain and rapid increases in body mass index (BMI) due to menopause. This study aimed to develop a basic bodice pattern suitable for women with a “square” body type, which is the most common type among Korean women in their 50s. We used a body shape avatar representative of square-body-type women in their 50s, provided by 6th Size Korea (KATS, 2010) as the model. This avatar was loaded into a virtual fitting program to evaluate the fit of the research pattern. The results of the study were as follows. Using the 3D virtual fitting program, the ideal bodice pattern was found to be close-fitting, based on an analysis of the body surface of women in their 50s with a square body type. This population’s characteristic body features included a rounded back, forward-protruding waist, forward-tilted neck, and shoulder tips angled toward the center-front. Because of the protruding abdomen, the bodice’s waist dart value was lower than average. The base bodice design for this body type was adapted from the research pattern of Jun and Jang (2024). Adjustments for this study included adding 0.5 cm to the center-back length and designing the profile line from the back neckline to the armpit wall. Further, the front bodice waist dart was omitted to accommodate the protruding abdomen. After two rounds of revisions, evaluations of the virtual fitting significantly improved, with scores increasing from 2.38 out of 5 to 4.82 out of 5.

This study aimed to develop a basic bodice suitable for the body shape of women in their 50s by using the CLO 3D virtual clothing program to create an avatar with the standard body presented in KATS (2022). A pattern was designed and produced using the CLO program, and the virtual fitting was evaluated. First, it was possible to confirm the slope (profile line) from the front center line to the point in front of the neck, the sagging shape of the breast, and the change in body shape due to the increase in bust circumference using the CLO program. Second, the change in body surface and body surface length according to movement was used to identify the profile line. The bust dart was very large. and the bust circumference showed the largest changes (5.05% in the 90° side and 1.5% of the breast width). Third, the total length reference line of the basic bodice was the back length (actual measurement). The total width reference line was the bust circumference/4+2cm and the breast width+0.5cm. The armhole depth reference line was the bust circumference/4–2. A profile line was created from the front neck circumference to the neck shoulder point to the breast point. Darts were formed on the back shoulder and back armhole lines. The allowances were 8 and 6cm for the bust and waist circumferences, respectively. All virtual fitting evaluation items improved significantly over two rounds (from 3.69/5 to 4.66/5 points).

본 연구는 중국 대학의 한국어 학습자를 대상으로 산출지향 접근법에 기반한 수업을 진행하고 그 수업 효과를 살피는 데에 목적이 있다. 이를 위해 본 연구는 산출지향 접근법의 이론에 대해 알아보고 이에 기반한 한국어 수업을 설계하여 진행한 후 학습자들을 대상으로 심층 인터뷰를 진행하였다. 산출지향 접근법에 기반한 한국어 수업은 주로 동기부여, 활 성화, 평가 단계에 따라 구체적인 활동을 구성하였다. 수업에 대한 인터 뷰 결과를 통해 학습자들은 새로 배울 내용에 대한 이해도와 흥미도가 높아졌고 보다 능동적으로 수업 활동에 참여하였으며 언어 산출 능력과 더불어 사고 능력과 동료 협력 능력도 향상되었음을 확인하였다. 반면 산출지향 접근법을 실제 수업에 적용할 경우 수업 시수의 부족, 학습자 언어능력의 부족으로 주어진 시간 내에 다양한 활성화 활동을 마무리하 기 어려울 것이라는 우려도 나타나고 있었다. 본 연구는 향후 POA에 기 반한 한국어 교육에 기초 자료를 제공할 수 있다는 데에 그 의의가 있 다.

This study aimed to suggest a suitable collar pattern by visually evaluating the appearance of the amount of collar drape by the starting position of the lapel line of a double-breasted tailored jacket using a 3d virtual fitting program. It created an avatar based on the mean size of women in their 20s (the 8th Size Korea) using clo network (double fastening: 10cm, collar width: 4.5cm, collar stand: 3cm, and lapel width: 8.5cm). The starting of the lapel twist line was waistline level, the 1/2 level of bustline and waistline, or bustline level, and collar laying amount was 4.5, 5.5, 6.5, or 7.5cm. It was evaluated by garment construction experts using 5, 6, and 4 items on the front, sides, and back, respectively. Descriptive statistics, F-test, Duncantest, and reliability analysis were conducted using SPSS 22. When collar laying amount was 6.5cm, it was best rated regardless of the starting point. Under waist line, when collar laying amount was 6.5cm, it was best rated regardless of the starting point. When collar laying amount was large, the collar’s outline length increased, resulting in unnecessary wrinkles from the neckline to the lapel, affecting the overall collar appearance. When collar laying amount was the smallest, the collar was lifted and the width was narrowed, exposing the seam connecting the collar and neckline. The length of the collar’s outline varied depending on collar laying amount, which was important to make the outline sit comfortably on the body.

In this study, the sales status of female ball-jointed dolls and their parts were investigated and analyzed. Baseline data from 194 products and 54 brands on domestic and international Internet sites was gathered for the manufacture of ball-jointed dolls and the development of prototype costumes for them. The results are as follows. First, the sizes used for ball-jointed dolls are SD, USD, MSD, 13SD, and 70SD together with height. This study analyzed 39 sizes (15~70cm) by classifying them into numbered groups: 1 (15~22cm), 2 (23~33cm), 3 (35~51cm), 4 (53~62cm), and 5 (63~70cm). The price varied depending on the size; for example, 50cm dolls were approximately 45,000 won, while limited editions were sold at high prices, regardless of their size. They were classified into designs according to their body proportions and facial features as follows: 7- or 8-head-figure, 5-head figure, and 3-head figure, and were presented proportionally as images of women, adolescents, and infants. Second, the head was incised so that the top could be removed horizontally or the facial region vertically, allowing attachment of the eyeballs (which were either glass, resin, or acrylic) to the inside. More than 30 different colors were sold. Various wig styles were provided, including cut, short hair, and perm. These were made from human hair, heat-resistant fiber, and artificial hair. For the hands, there was a design expressing human hand gestures. For the feet, heels were in the form of wearing either high-heels or flat soles.

본 논문에서는 선박 탑재 전자기기들이 외부의 전자파에 의한 장해와 과도 전압에 의해 전자파 간섭 또는 오동작을 방지하기 위한 목적으로 EMC 필터를 설계 및 제작하였다. 먼저 필터를 구성하는 인덕터의 경우 높은 투자율을 가진 Ni-Zn계열 페라이트 비드와 컨덴서의 경우 공진현상을 최대한 억제하기 위해 공진점이 없는 관통형 컨덴서를 이용하여 EMC 필터를 설계 제작하고, 그 특성을 평가하였다. 그 결과 0 kHz~1.5 GHz 광대역에서 25~70 dB의 우수한 감쇠특성을 얻을 수 있었으며, 과도진압의 경우, IEC 61000-4-4에서 규정하는 level 4에서 4 kV를 인가 시 600 V로 과도전압이 감쇠되는 특성을 얻음으로써, 선박 탑재 전자기기들 간의 전자파 간섭을 억제할 수 있음을 확인하였다.
