This treatise discussed the development and its applicability of the analytic methodology for the portfolio-based securities investment, and has reached the following conclusion. First, since current market indices such as stock prices and trading volumes reflect all the available past information, it is virtually impossible to gain extra profits by taking advantage of the past market information. Second, since current stock prices are those reflecting not only the past market information but also political/economic events, new information related to corporations and non-market information, it is hardly possible to earn extra profits by means of utilizing any kind of information that have already been made public. Third, current stock prices reflect not just publicized information but also special information discovered by the legitimate efforts made by investment professionals, and this make it impossible to raise any extra earnings by using any kind of information. This conclusion has a significance and a limitation as well in that this treatise has proposed another hypothesis that has to be verified repeatedly in accordance with changes in the type of the stock market and economic environment, together with the development process of various measures taken to cope with the complete opening up of the Korean capital market. On this point, further study and verification are to be conducted.

This study focuses on the phenomenon of manufacturing district in the inner city of Euljiro District being a subject of sightseeing without losing its original functional properties. ‘Eulji-Uram’ is a walking tour program that links various kinds of manufacturing firms, manufacturing-related retail shops, famous local restaurant and artists studios into one single route. This phenomenon implies a radical change in perception toward industrial district from ‘disqualified’ area into ‘subject of sightseeing’. By analyzing the characteristics of ‘sightseeing-space’ of the district, the study tries to understand the phenomenon in spatial dimension. To do so, the study is composed into two stages of research. First, the study examines the general characteristics of walking tour program within the boundary of Central Area of Seoul. The study draw out the spatial typology of walking tour route in terms of formal dimension, sightseeing-element and urban configuration. In the second stage, the study concentrates specifically on walking tour ‘Eulji-Uram’, in order to analyse the spatial characteristics of sightseeing route in Manufacturing District. The research method of second stage is to analyse the spatial characteristics of sightseeing manufacturing district by dividing the district into urban-composing element and industry-composing element. ‘Urban-composing element’ focuses on the formal characteristics while ‘industry-composing element’ focuses on the functional characteristics of the district. ‘Urban-composing element’ and ‘industry-composing element’ together implies overall industry-space relationship within the districts. Basing on these analysed elements, the result of the study can be sum up into three spatial characteristics of ‘sightseeing-space’. Firstly, industry that shares similar characteristics accumulated in a specific spatial configuration, would form cluster of space that contains unique sightseeing characteristics. Secondly, array of different characteristics of space would create sets of transformative spatial elements. Lastly, establishment of sightseeing route reveals some of the extreme condition of the streets that serves particular industrial purpose.

The Protective Effects of Zanthoxylum bungeanum Maxim Pharmacopuncture on Disuse Muscle Atrophy in Rat Gastrocnemius Muscle

정연중,이윤규,이봉효,김재수,이현종 대한침구의학회 2019 대한침구의학회지 Vol.36 No.4

Background: This study aimed to investigate the protective effects of Zanthoxylum bungeanum Maxim pharmacopuncture on disuse muscle atrophy in the gastrocnemius muscle of rats. Methods: Thirty male 250 g Sprague-Dawley rats were distributed randomly into 3 groups. The left hindlimb immobilization was performed with casting tape for 2 weeks, and no treatment was given to the right hindlimb. Rats received pharmacopuncture and were injected daily on the BL57 with either 2 mL of Zanthoxylum bungeanum Maxim aqueous extract (ZM-W group), 1 mL pharmacopuncture of Zanthoxylum bungeanum Maxim ethanol extract (ZM-E group), or 2 mL normal saline (control group). After 2 weeks of immobilization, the weight of the whole gastrocnemius muscle was measured, and the morphology of both the left and the right gastrocnemius muscles were assessed by Hematoxylin and Eosin staining. To investigate the immobilizationinduced muscular apoptosis, the immunohistochemical analysis of BAX and Bcl-2 was carried out. Results: ZM-W and ZM-E significantly inhibited the reduction in weight of the left gastrocnemius muscle, the reduction in the left myofibrils, and the cross-sectional area of gastrocnemius, as compared with the control. Moreover, the ZM-W and ZM-E groups showed significantly reduced immunoreactivity for BAX, and increased immunoreactivity of Bcl-2 in left gastrocnemius muscle compared with the control group. Conclusion: These results suggest that Zanthoxylum bungeanum Maxim pharmacopuncture has protective effects against immobilization-induced muscle atrophy by regulating the activity of apoptosis-associated BAX / Bcl-2 proteins in the gastrocnemius muscle.

하천 합류부 주변내 하수관거 방류조건에 따른 수위 및 유속 영향분석

도시지역의 우수를 배제하기 위한 방법으로 토구를 이용하여 하천으로 방류하고 있다. 그러나 이러한 토구를 설치 할 때 국내설계기준에는 어떠한 기준이나 제안이 없이 설계자나 시공자의 임의로 만들어 지고 있는 실정이다. 본 연구에서는 토구를 설치하는 방법에 대한 기초적인 자료를 제공하기 위하여 토구 방류 유량에 따른 흐름 변화 및 설치 각도, 돌출정도, 그리고 설치 위치에 따른 흐름변화를 실험을 통하여 분석함으로써 흐름에 보다 영향을 적게 미치는 토구설치 방법을 제안하였다. 총 10가지 경우에 대한 실험을 통하여, 같은 유량을 방류함에 있어서 한 곳으로의 방류보다는 상.하류 등으로 분리하여 방류하는 것이 흐름에 영향을 적게 미치는 것으로 나타났으며, 설치 각도 및 돌출에 따라 상류지역의 수위 상승 및 유속 감소 등의 현상이 나타나 토구 설치 시 보다 신중하고 흐름에 방해가 되지 않는 방향으로 설치할 수 있는 방안을 강구해야 한다. The rainfall runoff is drained through sewerage outlet at urban area. But, there is no guideline or standard to install sewerage outlet, so the sewerage outlet are designed or installed by discretion of engineers or constructors. In this paper, for the sake of supporting basic data to design, it would be suggested a guideline for less influenced to flow at the channel flow condition through hydraulic experiment by variation of lateral inflow discharge, sewerage outlet projecting part, sewerage outlet direction and position. Through 10 cases of experiments, it would be less influenced two sewerage outlet at up and down stream than one installed at up or down stream even though the same discharge. And installed conditions which are installed angle and protecting part will be influenced to increase water depth and to decrease velocity at upstream. So when sewerage outlet is installed, it would be try to find a installing way to be less influence with more careful.
