This article looks into Lee-Gyujun(李圭晙)'s life course, Confucian thoughts, and philosophical ideas on the Medicine of Boosting Yang(陽), by thoroughly translating and analyzing selectively the second half of Lee-Gyujun(李圭晙)'s "Seokgoksango(石谷散稿)". Translating his works is said to be necessary to fully understand the significance of the boosting-yang theory[扶陽論] in the historical landscape of Korean medicine, not to mention comprehension of the medical contents itself. Through this translation and analysis, first, it is found that Lee-Gyujun(李圭晙) had visited Seo-Changyu(徐贊奎) for over 10 years and had great influence on qi(氣) monism. Second, within the Gihohakpa(畿湖學派), Lee-Gyujun was much closer to Horon(湖論) rather than Nanron(洛論). Third, during his days, he became well known across the peninsula through his medical fame. Last, he wrote down the unknown manufacturing technique of dried ginger[乾薑].

2013년 설립된 부산일과학고등학교 천문대는 교육 및 연구목적으로 12인치 굴절망원경, 16인치 반사망원경 및 다수의 소형망원경들이 설치되어 있다. 우리는 본격적인 관측, 연구를 수행하기에 앞서 망원경의 다양한 성능을 검증하여 향후 연구 활동에 기초자료로 사용하고자 한다. 본 연구에서는 망원경에 4K CCD 및 DSLR을 장착하여 얻은 관측 영상으로부터 망원경의 추적 특성, 지향정밀도, 광학적 특성을 고찰하고, Landolt (1992)의 표준성을 이용한 BV측광을 수행하여 표준계변환의 특성을 조사하였다. 또한 산개성단의 BV관측을 통해 한계등급을 측정하였다. 이 연구결과로부터 향후 부산일과학고등학교 천문대에서 수행할 수 있는 적합한 관측 연구의 방향을 제시한다.

Natural indigo colorants were prepared by extraction of polygonum tintorium which was harvested just in the blooming season(in the late of July). The components were analyzed by TLC and HPLC, and its structures were analyzed by FT-IR, EI-mass and NMR. The dyeing mechanism and fermentation conditions were investigated. Its colour fastness was studied as well. The results obtained are summarized as follows ; The natural indigo powder was dissolved in DMSO and developed in eluent, $CHCl_3/CH_3CN(8.5:1.5v/v)$ by means of TLC for its quality analysis. It was segregated into indirubin as il red colour and indigo as a blue colour. In case of HPLC analysis, the retention times of indirubin and indigo were 7.442 and 6.543, respectively. FT-IR spectrum of indirubin showed a peak for NH residue between 3200 and $3300cm^{-1}.^1H-NMR$ spectrum for indigo displayed AA'BB' spin system caused by indole structure between 6.5 and 7.7ppm of H4, 5, 6 and 7, and -NH proton for indirubin showed an singlet between 10.88 and. 11.0ppm. EI-mass spectrum of indigo an d indirubin both disclosed their molecular size as 262 and it implies that these two substances are isomer.

Recently, the demand for demolition for the unnecessary steel frame structure is increasing due to deterioration and unsatisfactory functional conditions and the major highlights of demolition issues. This execution case was intended to describe an application of the felling method as one about the suggested method for explosive demolition method of ore bin and coke bin facilities, which were steel frame structures. And we used the charging container for blast cutting of the steel frame structure. As a result of the explosive demolition, the ore bin and coke bin had collapsed precisely according to the estimated direction. And the explosive demolition was completed without causing any damage to surrounding facilities.

Recently, the demand for demolition of unnecessary steel shell structure is increasing due to deterioration and unsatisfactory functional conditions and the issue of demolition is becoming a major highlight. This execution case was intended to describe an application of the felling method, a explosive demolition method to demolish steel shell structures, for the demolition of a steel stack and steel head tank. As a result of the explosive demolition, the steel stack and steel head tank had collapsed precisely according to the estimated direction. And the explosive demolition was completed without causing any damage to surrounding facilities.

Recently, the demand of demolition for the unnecessary industrial structure is increasing due to deterioration tendency and the issue of demolition is becoming a major highlight. The restoration of the dismantled industrial site to its original natural state was currently underway. This execution case was intented to describe an application of the felling method one of the explosive demolition method to the demolition of the industrial stack. This stack was 150m high, a composite structure in which the outer wall of the stack was a reinforced concrete shell structure and internal stovepipe was a steel shell structure. As as result of the explosive demolition, the stack had collapsed precisely according to estimated direction. And the explosive demolition was completed without causing any damage to surrounding facilities.

Recently, the demand for the dismantling of large-scale industrial structures is increasing, and the construction of restoring the dismantled industrial to their original natural environment is underway. This case was an application of the explosive demolition method to the demolition of a large section turbine foundation structure which structural obsolescence and failure to meet functional requirements. As a result of the explosive demolition, the fracture condition of the turbine foundation was satisfactory, and the explosive demolition was completed without causing any damage to the surrounding facilities.

Recently, the demand for the dismantling of old industrial complexes has been increasing, and the construction of restoring the dismantled industries to their original natural environment is underway. In this case, the felling method was applied to the explosive demolition method to dismantle a large steel frame structure in an old industrial complex. We used a charging container to cut the steel frame structure that generates a metal jet. The thickness of the thick steel structure in the blasting section was controlled by gouging which a method of digging deep groove by gas and oxygen flame or arc thermal. As a result of the explosive demolition, the steel frame structure collapsed precisely according to the estimated direction. The explosive demolition was completed without causing any damage to the surrounding facilities.

타액은 분비율과 그 구성성분으로 인해 구내환경을 조절하는데 있어 가장 중요한 요인으로 여겨진다. 타액 분비율과 성분에 관한 많은 연구가 이루어 졌지만, 증령이 타액과 그 성분에 미치는 영향에 대한 연구는 상반된 결과를 보고하고 있으며 현재까지도 논란의 여지가 많다. 또한 증령에 따른 lactoferrin과 전해질의 변화는 거의 보고되지 않은 실정이다. 이에 저자는 증령이 타액분비량과 타액성분에 미치는 영향을 연구하기 위하여 59명의 투약력이 없고 건강한 사람을 대상으로 연구를 시행하였다. 연구대상을 그들의 나이에 따라 A군, 10~15세 (남자7명, 여자7명); B군,20~30세 (남자8명, 여자7명 ); C군,40~50세 (남자7명, 여자7명 ); D군,60세 이상 (남자7명, 여자9명 ) 등의 4군으로 구분하여 각각의 비자극성 전타액을 표준화된 방법으로 채취한후 타액분비량과 immunoglobulin, lactoferin 및 전해질의 변화를 측정하였다. 이와 같은 실험을 통해 다음과 같은 결론을 얻었다. 1. 비자극성 타액분비량은 각 연령군간의 유의한 차이가 관찰되지 않았으며, 20-30세 군(B군)에서만 남성에 비해 여성에서 유의하게 낮았다. 2. 인체 전타액내 IgA와 lactoferin 농도는 연령이나 성별에 따른 뚜렷한 변화는 없었지만, 10-l5세 군(A군) 남성에서 유의하게 낮았다. 3. 인체 전타액내 IgG의 농도는 연령이나 성별에 따른 차이가 관찰되지 않았다. 4. 인체 전타액내 IgM의 농도는 60세이상 군(D군) 남성에서 유의하게 낮은 농도를 보였다. 5. 인체 전타액내 전해질(sodium, chloride, potassium, magnesium)의 농도는 증령에 따라 증가하는 경향을 보였다. magnesium과 chloride는 60세이상 군(D군)에서, sodium과 potassium은 40-50세 군(C관)에서 최대치를 보였다 성별간의 유의성 있는 차이는 발견되지 않았다.

This paper examines how 'house' is meaningful in Chi Li's novel. Chi Li focuses on the house as a symbol of status, and the house as a place of gender performance. First, as a sign that symbolizes an individual's identity, 'house' is divided into intellectual and petit bourgeois, and constitutes binarism into civilization/non-civilization, knowledge/non-knowledge, spirit/anti-spirit and superior/inferior. In recognizing the irrationality and unfairness behind house symbolizing intellectual and petit bourgeois, Chi Li shatters the boundaries of the binaralized house as a sign of identity. Second, it dismantles the house as a place where gender is (re)produced. This is accomplished through two aspects. One is to re-define a private area house as a public area in which economic activity occurs. The house, as a public area in which economic activity occurs, becomes a place where women are reborn as economic entities. Passive, dependent femininity is reconstructed as independent and subjective. The other dismantles the definition of the house which is identified with masculinity. The house identified with masculinity is a place that symbolizes the socio-economic capacity of men. According to the socio-economic ability of males, the house is a place symbolizing the realization of masculinity, and it becomes a place to fix the gender order while reproducing masculinity. It may become a place to experience the weakening or defamation of masculinity. At that moment, the house becomes a place where the gender order of masculinity and femininity is overturned. Through this, Chi Li reconstructed, and in a sense revolutionized the definition of the house as a place where traditional gender is (re) produced by dismantling the definition of fixed femininity or masculinity.
