김용찬 배화여자대학 1999 培花論叢 Vol.18 No.-

Particle size distribution of pine pollens was investigated by laser diffraction method. Size distribution pattern, surface area per volume, mean particle size were different among five pollens with different local origins. When pollen was wet particle size increased from 24% to 75% for maximum size(99% distribution) and 12-18% for mean size(50% distribution) depending on locality. These results were well consistent with light microscopic data and bulk density. Pollen size showed normal distribution with dual peak either separated or overlapped in the large size. Mean size of dry pine pollen ranged from 40 to 51㎛, minimun(10%) from 31.3 to 39.8㎛ and maximum(99%) from 59.3 to 115.9㎛. Volume surface ranged from 0.12㎡ to 0.222㎡/㎤. Bulk density was 0.25g/㎤. Particle size distribution by laser diffraction method will be useful to assess pine quality, local origin and plant origin

秦·漢의 가축·육류 관리와 官制의 변화

김용찬 경북대학교 인문학술원 2022 동서인문 Vol.- No.20

倉(Warehouse), which produced and stored livestock and meat used as sacrifices in ancient China, was the center of gathering and distributing all edible materials to the state power. During the transition period between the Qin and Han Empires, 苑(Pasture) and 廐(Stall) became in charge of rearing and managing large livestock, and 倉(Warehouse) and 廐(Stall) formed within local administrative units. The 倉(Warehouse) and the 廐(Stall) were managed by 內史(Chamberlainship for the Capital) and replaced the task of 太倉(Grand Warehouse). After the unification by the Qin Empire, a symmetrical structure of 中(Center) and 郡(Prefecture) was created. The task of 倉(Warehouse) was divided into two╶ 內史(Chamberlainship for the Capital) became responsible for one and 郡(Prefecture) took charge of the other one. The status of 太倉(Grand Warehouse) became lower than the 內史(Chamberlainship for the Capital), and 太倉(Grand Warehouse) lost control over the 苑(Pasture) and 廐(Stall). From the transition period between the Qin and Han Empires to the middle of the Former Han period, the production activities carried out in the local administrative unit of 中(Center) under the management of 內史(Chamberlainship for the Capital) were passed down to 左內史(Left Chamberlainship for the Capital) and 右內史(Right Chamberlainship for the Capital) and then, finally, to 京兆尹(Jingzhaoyin) and 左馮翊(Zuofengyi). The 大倉(Grand Warehouse), 太倉治粟(Granaries of Grand Warehouse), and large warehouses were all under the jurisdiction of the 治粟內史(Chamberlainship for the National Treasury). As a result, 治粟內史(Chamberlainship for the National Treasury) took care of items, even including “inedible” ones, and 大農令 and 大司農(Ministry of Revenue) later continued the role. The Han Empire placed a gap between central and local governments and created a new system where central ministries were responsible for work beyond 中(Center) and that spanned the world(天下). As a result, the work of 內史(Chamberlainship for the Capital), which was in charge of production activities of 中(Center), was divided to central ministry 治粟內史(Chamberlainship for the National Treasury), which duties extended beyond the borders of 郡(Prefecture) and 諸侯國(Kingdom), and the provincial ministries 左內史(Left Chamberlainship for the Capital) and 右內史(Right Chamberlainship for the Capital), which were only responsible for local administrative units belonging to 中(Center). The division of 中(Center) and 郡(Prefecture), solidified during the unification by the Qin Empire, was separated into the central government ruling the world(天下) and the local governments including 郡(Prefecture) and 國(Kingdom) by the Han Empire and established the superiority of the center, emperor, and state power over the local. In order to rule the world(天下), including 郡(Prefecture) and 國(Kingdom), 大司農(Ministry of Revenue) of the Former Han Empire became a huge government office. In contrast, 大司農(Ministry of Revenue) of the Later Han Empire was very simple. This change is related to the mid-Former Han Empire’s situation where livestock and meat production by the private sector developed and the consumption of those became common. Eventually, there was no need for the government offices to be involved in the production and distribution of those goods, and the 太僕(Ministry of Coachman), which was in charge of breeding and managing public livestock, was also greatly reduced in size. This was not due to the weakened influence of the state power, but was a measure formed from compromising with reality, such as a decrease in the demand and an increase in the private sector’s productivity, and should be understood as a natural phenomenon. 太常(Ministry of Ceremonials), the highest office in charge of sacrifices since the Qin Empire, also disappeared from the process of sourcing ...

수중운동이 비만중년여성의 신체조성과 심박변이도에 미치는 영향

본 연구는 수중걷기 운동과 수영운동을 병행한 수중운동이 비만 중년여성의 신체조성과 심박변이도에 어떠한 영향을 미치는 지를 알아보는 것이다. 본 연구 대상자는 체지방률 30% 이상인 40~50대의 비만여성 20명을 비운동집단과 운동집단으로 구분하였 다. 운동집단 군은 최대심박수 60%의 강도로 일주일에 3번 수행하였고, 각 집단의 수중운동 프로그램 실시 전, 후의 신체조성과 자율신경계 변화를 관찰하여 다음과 같은 결과를 얻었다. 운동집단의 경우 체중과 체지방률에서 현저하게 감소를 보였으나 비운 동집단의 경우 모두 유의하게 증가하였다. 심박변이도 분석에 의한 자율신경계 변화에서 운동집단의 경우 SDDN, TP, HF에서 유 의하게 증가하였지만 LF에서는 감소하였다. 비운동집단의 RMSSD와 TP에서 현저하게 감소를 보였다. 결론적으로 신체조성과 심 박변이도는 밀접한 관계가 있고, 비만 중년여성의 수중운동은 체중과 체지방률 감소와 그에 따른 교감신경 활성감소, 부교감신경 활성 증가 그리고 교감-부교감신경 균형에 긍정적인 효과를 미치고 있는 것으로 사료된다 This study investigated the effects of aquatic exercise program that combination water walking exercise with a swimming exercise on body composition and a heart rate variability (HRV) modification in the middle aged obese women. The subjects of this study 20 obese middle aged women randomly selected who were in their 40s and 50s over 30% of body fat percentage, were divided into non-exercise group (n=10) and the exercise group (n=10). The exercise group was performed at 60% HRmax three times a week, and then each group aquatic exercise program carried out before and after the changes in body composition and the autonomic nervous system, the following results were observed. In the exercise group, the body weight and body fat percentage significantly decreased (p<.05) but non-exercise group increased. Changes of autonomic nervous system by HRV analysis showed that the SDDN, TP, HF significantly increased but decreased at LF in the exercise group. Whereas the RMSSD and TP a significant reduced in the non-exercise group. Consequently, This study is considered to suggest the aquatic exercise program lead to decreased sympathetic nerve activity, increased parasympathetic activity and sympathetic-parasympathetic balance due to th body weight loss and body fat percentage reduction, in obese middle aged women.

국소적 대상포진이 발생한 면역저하환자로부터 유발된 수두의 발생

Varicella zoster virus causes chickenpox, which is highly contagious, at primary infection and herpes zoster at reactivation. The varicella zoster virus may be more contagious and cause serious outbreaks in immunocompromised patients. There are some reports of outbreaks of chickenpox in patients with herpes zoster. Here, we describe a case of localized herpes zoster occurring in an immunocompromised patient during hospitalization in a specialized ward for immunocompromised patients. This episode resulted in two newly developed, hospital-acquired cases of chickenpox. If we had isolated the index patient who had localized herpes zoster immediately, the two cases of chickenpox could have been prevented. Therefore, patients with localized herpes zoster should be isolated in wards with immunocompromised patients.

Some properties of fuzzy net-convergences

김용찬,고정미 한국지능시스템학회 2004 한국지능시스템학회논문지 Vol.14 No.1

In this paper, we introduce the fuzzy limit degrees in -fuzzy topologies using complete MV-algebras. We investigate the properties of net-convergences (the degrees of fuzzy convergent, fuzzy cluster, fuzzy adherent points and fuzzy limits).
