This study attempted to numerically verify specific effects on skin condition improvement by measuring and comparing changes in skin conditions such as pores, wrinkles, and sebum of LED masks for beauty devices with low output among light sources. 18 healthy women (4 weeks in the control group and 4 weeks in the experimental group) were conducted once a week for 8 weeks. As a result of measuring the skin condition of pores, wrinkles, and sebum, it was confirmed that the skin condition improved significantly as the LED irradiation progressed, and the difference between the groups by measurement period of the experimental group and the control group also showed significant differences in pores, wrinkles, and sebum (p< .001, p<.05). This is meaningful in that it can be presented as clinical information and quantitative data by preparing continuous data in an academic sense by proving the effect of improving the LED mask as a beauty device. It is also suggested that in the future, follow-up studies to prove more effective skin improvement will be conducted.

Serial violent crimes have occurred more frequently. Additional attention is paid to relevant areas in which discussions has also increased. This study analyzed Young-cheol Yoo, serial killer case. Two of Yoo's crimes were studied for modus operandi. The cases selected were the premeditated break-in homicide of upper-class elderly people and the impulsive homicide of the Hwanghak-Dong street vendor. Crime motives, targets, times, places, means and methods were analyzed. Profiling techniques in Young-cheol Yoo cases were evaluated and the problems discovered during investigation were discussed. The followings are the findings of the analysis of the serial killer Yoo cases. Yoo exhibited a hatred toward the rich, the elderly, and women as well as a fear of diseases and death. Yoo's crime targets were the elderly residing in wealthy houses, street vendors and prostitutes. The numbers of victims were: 3 men and 5 women victims in 4 homicide cases involving the elderly residents in wealthy houses; one man in 1 street vendor homicide case 11 women in 11 prostitute homicide cases, so total 20 persons were murdered in 16 cases. The time of the crimes were between 10 am and noon in the homicide cases of the elderly and very late at night or early in the morning in the prostitute homicide cases. Means and methods facilitated include the use of a knife as a threat and a hammer made by Yoo to strike the head and face of victims. In the homicide cases involving the elderly, he attempted to disguise the crime scene as a burglary or committed arson to destroy the evidence; in the prostitute homicide cases, bodies were mutilated and buried in secret. 1) Generally each serial killer case has different characteristics, motives, and purposes; while some serial killer cases involve similar methods, others use different methods. Unlike other crimes, serial killers' characteristics and tastes are very different, so it is difficult to explain serial killings based on a specific model. It is important to accurately capture modus operandi of each serial killing and for detectives to familiarize themselves with them. The process of tracing and use of imagination which follows a serial killer's psychology and thought must be used to find out what kind of thoughts pushed the killer to commit the crime. In order to investigate and research difficult subjects such as serial killing, various methods, skills, and relevant knowledge should be studied, and institutional endeavors should go hand in hand with individual efforts.

As the 21century enters information era, female scientists and engineers are expected to play important roles more than ever. In Korea, female s roles in such areas have been traditionally limited. In order to find the effective ways of boosting those roles in a social network, we employ an SEM (Structural Equation Model) where the relationship between various factors and the satisfaction level of women scientists and engineers is examined. We expect that the results obtained from this analysis can contribute to improving the environment of women scientists and engineers in each field.

현재 전 세계적으로 태풍, 지진, 홍수 등의 재해 피해가 빈번히 일어나고 있고, 4차 산업의 발달로 인한 AI기술을 활용하여 자연재해 전반을 예측 할 수 있는 시스템이 도입될 정도로 과학적으로 발전 되어진 반면에, 재난으로 인한 인명 피해 수를 저감 시키는 방향을 도모 하는 데에는 어려움이 있고, 국민들의 재난피해의식도 심각 하지 않은 추세이다. 이와 같은 문제점을 파악하기 위해 한국 국민 남녀 489명을 대상으로 재난위험인식에 대한 설문을 작성하여 조사를 진행하였다. 본 연구의 목적은 국민들의 재난 안전의 위험도에 대한 인식 수준이 어떠한지 분석하고, 영향 요인을 탐색 하는 데에 있고, 조사결과 안전취약계층은 스스로 대피 하는 데에 있어 큰 어려움이 있으며, 이중 여성은 남성에 비해 안전교육과 훈련의 접근성이 적음에 따라 위험도가 더 큰 것을 확인 할 수 있었다. 본 연구를 통해 재난 안전교육의 필요성을 가지고 재난 안전 시뮬레이션 프로그램이 구축되는 필요성이 있다고 사료되어지고, 미래에 자연재해 발생 시 문제점을 파악하고 인명피해 감소가 될 전망으로 기대가 된다.

텍스타일의 발전에 있어서 진보적 기술혁신은 합성섬유의 잠재력을 높이는데 큰 촉매 역할을 해왔는데 그 중 가장 두드러지게 성공적인 분야는 바로 스트레치 직물 분야이다. 스트레치는 그자체의 다양한 종류와 변화무쌍한 특성과 함께 스포츠 웨어, 캐주얼웨어 뿐 아니라 최근에는 정장류 남성복에 이르기 까지 그 사용범위와 미적 표현이 크게 증가되고 다양해졌다. 스트레치의 미는 기능적이고 편안하면서도 직물자체의 유동적인 특성과 함께 인체와 더불어 표출되는시각적 이미지가 현대미에 새로운 개념을 더하고있다는 데에 그 가치가 있다. 본 연구목적은 현대 패션디자인에 표현되어진 스트레치의 미적 개념과 가치가 무엇인가를 발견하는데 있다. 특히 섬유과학기술의 진보로 인한 스트레치 직물의 다양함과 그에대한 디자이너들의 패션철학과 디자인의 다양한 변화를 강조하고 나아가 다음세기를 위한 보다 나은 디자인의 방향을 제시해 보고자한다. 연구결과는 다음과같다. 1, 스트레치의 가장 두드러지는 현대적 미는 편안함과 기능성에 있다. 특히 스트레치 직물 자체가 더욱 가벼워지고 강해지면서 현대생활과 미래생활에서 가장 크게 중시되고 있는 comfortable & functional 의 이상적인 개념을 충적시켜 주고 있다. 2. 스트레치 직물의 유동적특징에서 대표적으로 나타난 스타일은 바디스트인데 이것은 스트레치 자체의 신축성이 기본적으로 인체곡선 위에서 표현되어진 것으로서 거의 비슷한 스타일의 uniformity 현상을 낳게 되었고 또한 인체선의 드러남으로 인해 'healthy'이미지 추구라는 현대미의 새로운 개념을 가져왔다. 2. 더욱 정교해진 스트레치는 결국 transparent look을 낳았고 또한 비치는 직물들을 겹쳐입는 layering 현상을 가져왔는데 이것은 현대적 순수미와 여성미가 시감각적 이미지로 표현되어진 것이라 할수 있다. 4. 스트레치가 되므로서 생기는 긴장은 다른 디자인 요소들에 대해서는 극히 단순한 것을 요구하면서 결국 simplicity를 동반하게 되었다. 5. 스트레치는 디자인 구성 요소들의 보다 작은 개념을 낳았는데 즉 더욱 좁아진 형과 작아진 사이즈 없어지거나 줄어든 다트와 구성선 그리고 그에따라 줄어든 공정과 낮아진 가격이다. 이 개념은 현대미의 minimalism의 한 현상으로 해석되어지며 스트레치 직물은 여기에 가장 부합되는 소재가 되었다. 6. 스트레치의 시각적 이미지는 그자체가 'easy' 'free'느낌과 함께 보편적이면서 미래적이다. 이상으로 볼 때 미래의 패션은 보다 진보적인 섬유과학발전에 힘입어 21세기의 새로운 환경에 잘 적응 할 수 있는 합리적이면서도 미적 가치가 내포된 인간에게 보다 친숙한 디자인으로 전개되리라고 생각되어진다.

Purpose: To evaluate the correlation between BMD and life habit such as drinking. exercise smoking or physical condition such as age, sex, height, weight, body mass index(BMI). Materials and Methods: I evaluated the BMD of the femoral neck and L2-L4 spines of 321 persons who took a regular health screening in Woosuk university oriental medical hospital from February to April in 2006 by dual energy bone mineral densitometry. Results: The age of persons ranged from 20 years to 75 years(mean $45.10{\pm}11.54$) and there were 160 males and 161 females. In males, BMD of the femoral head was highest at 2nd decade, BMD of the spine was highest at 4th decade, and BMD of both femoral head and lumbar spine was lowest at 6th decade. In fenales, BMD of both femoral head and lumbar spine was highest at 4th decade and lowest at 6th decade. Among the various physical conditions, only height of persons showed significant correlation with BMD in both males and females. BMD was increased according to increasing height. In males, BMD of persons who had habit such as drinking, exercise or smoking did not show significant change statistically. But in females, drinking group showed high BMD relative to non-drinking group in both femoral head and lumbar spine. Conclusion: BMD was different according to age, sex, height and life habit. Especially aged people showed osteoporotic change progressively. More persistent effort is needed to find out the factors decreasing BMD for prevention of problems by osteoporosis.

The study found out developmental factors of the liver diseases in 29, 531 cases of the healthy adults who were diagnosed by using ultrasound at domestic healthcare centers in 6 cities. The results are as follows. Based on the result of the study, the liver diseases diagnosed by using ultrasound was revealed to show 43.1% of prevalence, and the occurrence was significantly higher in male (23.3%) than in female (19.8%). The prevalence of hepatic diseases related to the BMI was revealed to show highest prevalence of the fatty liver in obese group (BMI $\geqq$ 25) by recording 44.3%. Smoking contributed to the high prevalence of all liver diseases. Although the fatty liver was the most frequently occurred form of liver diseases by recording the prevalence of 49.1% (22.2% in male, 26.9% in female), the significant difference was found only in female (p < 0.05), but male group did not show significant difference (p > 0.05). The prevalence of hepatic diseases related to the hypertension was revealed to show highest prevalence of the fatty liver in hypertension group by recording 67.7%. The prevalence of hepatic diseases related to the diabetes was revealed to show highest prevalence of the fatty liver in diabetes group by recording 66.2%. The high prevalence of all hepatic diseases was related to diabetes mellitus with statistical significance (p < 0.001). The multiple regression analysis for the related factors which affect the prevalence of the liver diseases showed the higher prevalence by age. Sex, obesity and diabetes mellitus were positively related to the prevalence (p < 0.05) while hypertension and smoking showed no significant relationship to the prevalence of the disease (p > 0.05).

This article describes the fear of infection through the Covid19 pandemic and the rapid phase change of human species with H. P. Lovecraft's fiction and "Project LC. RC". Pandemic and climate change, which can be called global weirding, fundamentally question the status and history of human species in the ecosystem. The horror creature and cosmological indifferentism in Lovecraft's weird fiction are contemporary in that they help shed light on today's global weirding. But Lovecraft's racism allows him to ask more fundamental questions about the logjam of his cosmic horror. "Project LC. RC" are a Korean writers's works of cultural variation that rewrites controversial racism and misogyny in Lovecraft's fiction. Such variation becomes the task of creating a mutation in Lovecraft as it becomes infected with the affection of Lovecraft's writing. This article first noted the creative power of Lovecraft's fiction that induces such a mutation. And under this premise, this article wanted to reveal the meaning of Lee Seo young, Eun rim, and Kim Bo young's recreates of Lovecraft's fiction through the analysis of images and motifs of abject, plant creature and symbiosis. Specifically, Lovecraft's creature, which evokes phallic fear, turns into an image of an abject embracing and comforting women's despair("I Want You to Stay Low"), a plant creature that provides women with refuge("Color in the Well"), and a creature of care and symbiotic life("A Sea of Plague"). This recreate/rewriting has contemporary significance in that it embodies values such as labor, care, and solidarity in their works. The conclusion noted another power of creative variation in Lovecraft's fiction, which is not reduced to recreate/rewriting.
