The gait characteristics and shapes of human foot are changed by their diseases and habits. Especially, it is known that the size and shape of foot of the elderly(aged) differ from these of youth foot, because of muscle degeneration and wearing footwear for a long time. Therefore, to design and make last for the elder footwear, anthropometric data measured elder feet and classified their foot type will be necessary. Nevertheless, elder footwear has been designed and made by using the same last of the youth. Therefore, to design elder footwear, we measured 49 anthropometric data on foot of the 252 elderly males and females, and classified their foot shape and type according to FI(foot index) and MPA(matarars-phalanx angle) in this study. The results showed that the elderly has a tendency of slenderizing on foot compare to the youth, and elderly females have more deformed foot type than elderly males. The results can be provided as basic information to the design of elder footwear.

Podocytopathy is glomerular lesions characterized by podocyte injury. It is observed in various glomerular diseases, but minimal change disease and focal segmental glomerulosclerosis (FSGS) are the prototypes. In this review, morphologic features of podocyte injury and subtypes of FSGS will be reviewed briefly. Effacement of podocyte foot processes is the most common feature of podocyte injury. As podocytic injury progresses, intracytoplasmic vacuoles, subpodocytic cyst, detachment of podocytes from the glomerular basement membrane and apoptosis develop. Glomerular capillary loops in epithelium-denuded area undergo capillary collapse. Synechia and hyalinosis may accompany this lesion. To manifest segmental sclerosis, podocyte loss above a threshold level may be required. Injured podocytes can injure neighboring intact podocytes, and thereby spread injury within the same lobule. FSGS can be categorized into five subtypes by morphologic characteristics; not otherwise specified (NOS), perihilar, cellular, tip, and collapsing types. Each subtype has been reported to show different clinical courses and associated conditions, but there are controversies on its significance. With recent progress in the discovery of genetic abnormalities causing FSGS and plasma permeability factors, we expect to unravel pathophysiology of FSGS and to understand histological sequences leading to FSGS in near future.

Three lipoxygenase isozymes in soybean seeds are thought to be a major contributor to lipid peroxidation and generation of free radicals which may result in seed deterioration. This study was conducted to get the basic information for changing lipoxygenase activity during seed germination in lipoxygenase-lacking soybeans. Fresh weight of soybean seedling of Jinpumkong 2 and Taekwangkong increased more rapidly than that of Jinpumkong. Hypocotyls of Jinpumkong and Jinpumkong 2 were longer and thicker than that of Taekwangkong. Type I lipoxygenase activity (pH 9.0) in cotyledon of Jinpumkong lacking lipoxygenase-2, 3 showed higher than that of Taekwangkong, and Type I lipoxygenase activity of two cultivars decreased continually. On the other hand, Type II lipoxygenase activity of Taekwangkong began to increase continually two days after germination, reached to the maximum between 4 days and 5 days, and began to decrease continually five days after germination. Type I and II lipoxygenase activity in hypocotyls was not detected in all soybean cultivars.

The purpose of this study was performed to analyze the trend of foot reflexology and effectiveness. This study analyzed 118 articles published over 20 years on the effect of intervention therapy. Year of presentation, type of research, characteristics, results of intervention variables, and so on of preceding papers on foot reflexology were analyzed. Collected data were analyzed using SPSS/PC Ver. 26.0 statistical program. Results of this study confirmed that foot reflexology therapy was effective in psychological state, physical state, body systems, vital signs, lipids, and blood. Results of this study could be used as basic data for the development of interventional methods of foot reflexology for human health.

발전용 터빈은 현대생활의 기본을 이루는 전기를 만들기 위하여 보일러에서 생 산된 열에너지를 기계적 에너지로 전환하는 장치로서 발전효율 상승과 경제성 때문에 그 단위기 용량이 대형화 되고 있는 추세이다. 특히 원자력 발전 설비는 화력발전설 비에 비하여 거의 두배에 이르는 용량으로 건설되어 원자력발전용 터빈의 중요성이 증대 되고 있다. 본 연구에서는 원자력 발전용터빈로타의 운전유형별 열응력해석을 수행 하여 현재 운용중인 발전용 터빈로타의 운전조건을 검토하고부하추종 운전의 타당성 검토기본자료로 활용코자 하였다.

인간의 보행에는 다양한 분야에서 유용하게 사용할 수 있는 정보를 가지고 있어 의료분야와 수사기관에서 사용되고 있다. 보행 데이터로부터 유용한 정보를 얻어내기 위해 선행되어야 하는 작업은 보행주기를 판별하는 것이다. 본 연구에서는 보행주기 판별을 위하여 발 뒷굽 닿기와 발가락 떼기 행동을 가속도 값과 각속도 값을 사용하여 알아내고, 정확도를 분석하는 알고리즘에 대해 논한다.

This study aimed to examine the differences in gender equality consciousness between latent profiles based on corporate workers' organizational culture types. To achieve the study's purpose, descriptive statistics, correlation analysis, and latent profile analysis (LPA) were conducted using 253 Korean corporate workers' data. As a result of the analysis, the latent profiles of organizational culture recognized by corporate workers were classified into 5 profiles. We named each profile as high compete-low create culture, high compete-low collaborate culture, collaborate culture, high create culture, and high control culture based on each profile's organizational culture perception. The ANOVA test found statistically significant differences between the groups in the gender equality consciousness. This study is meaningful in that it reveals the relationship between the organization culture perception and the gender equality consciousness and suggested implications for the organizational-level intervention to improve the gender equality consciousness. It will provide basic data for your research.

투구꽃속(Aconitum L.)은 미나리아재비과(Ranunculaceae)의 가장 큰 속(Genus) 중 하나로 300-400 여종(Species)이 북반구 온대지역에 분포한다(Tamura, 1993). 둥근 투구모양의 꽃받침이 특징적이며, aconitine과 같은 알칼로이드 성분을 함유하고 있어 전통적으로 약용소재로서 활용되었다(Khorana, 1968). 세뿔투구꽃(Aconitum austrokoreense Koidz.)은 한국 경상도, 전라남도에만 국지적으로 자라는 한국 특산식물이자, IUCN에서 CR(Critical Endangered) 등급으로 지정된 희귀식물이다. 이 종은 다년생이지만, 서식지에서 개체수가 적거나 유묘의 발견이 어려운 등 자생지 축소 및 절멸의 우려가 높다. 세뿔투구꽃을 보호하고 종을 보존하기 위해서는 종자 발아 · 휴면에 대한 지속적 연구와 종자번식법의 개발이 필요하다. 본 연구에서는 세뿔투구꽃의 종자의 휴면유형을 분석하고 호르몬에 의해 휴면타파를 유도하였으며, 특히 발아 2단계에서 일어나는 생리적 변화를 단백질체학적 관점에서 분석하였다. 세뿔투구꽃 종자는 미발달된 배를 가지고 있으며, 충분한 수분과 온도의 조건에서도 발아가 관찰되지 않아 형태 · 생리적 휴면으로 판단되었다. 종자는 BAP 처리에서 휴면이 타파되는 것을 확인하였으며, 특히 BAP 농도에 따른 발아율은 통계적으로 유의한 값을 가졌다 (F=23.208, P<0.01). 건조된 종자에 비해 BAP 처리된 종자는 발아 2단계에서 몇가지 단백질의 증가가 관찰되었다. 대부분의 종자는 30S ribosomal protein subunit으로, 휴면상태에서 발아상태로 변환이 일루어지는 생리적 변화의 증거로 확인된다. 특히 발아2단계를 지나는 세뿔투구꽃 종자에서는 cytochrome subunit과 photosystem II protein의 급격한 증가가 관찰되었는데, 이는 배아의 발달 결과인 자엽이 발아 즉시 광합성이 가능하도록 준비하는 과정에서 발현 된 것으로 추정한다. 본 연구는 발아2단계에서 휴면타파에 직접적인 영향을 미치는 요인을 발견하지 못하였으나, 휴면타파에 중요한 단계인 발아 2단계 종자의 생리학적 변화를 이해하기 위한 기초자료로 활용 될 수 있을 것이다.
