국민의 식생활과 건강보조식품의 필요성에 관한 연구

이정수 대구산업정보대학 1995 논문집 Vol.9 No.2

As mentioned above,we know that the intake of food by people in our country has nearly approched the encouraged amount of nutrition. Based on this fact, many nutritionists conclude that there is no health impediment due to malnutrition, for the nutritive condition of Korean people today is much better than that in the past,and the intake of food and the encouraged amount of nutrition are nearly balanced. Nevertheless, we should not overlook a few points:imperfection of the encouraged amount of nutrition itself;probable imbalance of nutrition due to excessive intake of manufactured food and fast food;the menace to human health due to theaggravation of environmental pollution ; and probable malnutrition due to the destruction of nutrients during the process of cooking because of imperfect education for nutrition. Therefore, in order to maintain the necessary balance of perfact nutrition, we should duly consider the following points : 1. Elimination of environmental pollution. 2. Consumption of food and drink with natural nutrition(without the process of manufacture and cooking) if possible. 3. Reduction of the intake of manufactureed food as much as possible. 4. Consumption of high fiber food and low carbohydrate food if possible. Putting aside various points of view,we can see that the condition of human health is always threatened by various factor even though the dietary life for human health has nearly approached the encouraged amount of nutrition. Therefore, we should empasize the necessity of preventive measure or improvement of supplemental food for human health.

간접포기식 유동상법에 의한 폐수처리 특성에 관한 실험적 연구

이정수,김환기,Lee, Jeoung Su,Kim, Hwan Gi 대한토목학회 1994 대한토목학회논문집 Vol.14 No.2

본 연구는 간접 포기식 유동상법을 이용하여 유입상승유속과 충전 메디아량의 변화에 따른 생물막의 두께, 미생물 농도, 처리효율 등을 관측하였다. 사용 메디아로는 0.42~0.6 mm 입경범위를 갖는 모래를 이용하였으며 BOD 용적부하율은 $4.2kg-BOD_5/m^3{\cdot}d$로 고정하고 이때 실험을 위한 조건 변화의 범위는 순환유속의 경우 1.03~2.56 cm/sec, 충전 메디아량은 $87.9{\sim}439.1kg/m^3$으로 하였다. 실험결과 미생물막은 모래 충전량에 관계없이 순환유속이 1.17~1.32 cm/sec일 때 가장 잘 형성되었으며 최고의 처리효율을 보일 때의 메디아 충전량 및 이때의 순환유속은 각각 $261kg/m^3$ 및 1.35 cm/sec였다. 상기의 최적 조건하에서 유출수의 SS농도는 약 9.5 mg/l이고, 측정된 미생물막의 건조밀도는 순환유속 및 메디아 충전량에 관계없이 5.6%로 거의 일정하였으며 이때 미생물이 유기물을 제거하는데 있어 미생물의 활성을 저하시킬 수 있는 산소의 최소농도는 약 4 mg/l였다. The wastewater treatment characteristics of the fluidized bed filled with sand media and intermediately aerated were studied experimentally, and the obtained results were as follows; 1. The formations of biofilm on the media were greatly affected by the recirculation velocities. 2. Under the experimental condition that BOD loading rate was $4.2kg-BOD_5/m^3{\cdot}d$, the optimum media concentration was $261kg/m^3$ and the optimum recirculation velocity 1.35 cm/sec. 3. For the effluent quality of 20 mg-BOD/l and 20 mg-SS/l, the maximum allowable loading rate was about $8kg-BOD_5/m^3{\cdot}d$. 4. The dry density of biofilm was about 5.6% regardless of the filled media quantities and recirculation velocities. 5. Under the experimental conditions, the effluent solids concentration was below 20 mg/l, and the elimination of final clarifier can be expected.

언양호적대장 협호의 존재 형태와 노동 특성

이정수,김희호 부경역사연구소 2013 지역과 역사 Vol.- No.32

Using the register records of Eoan-Yang area in 1711-1861, this study examines the labor patterns and socio-economic characteristics of Hyup-In in the late Chosun Korea. In particular, socio-economic characteristics such as populations, ages, sex, and household composition ratio are investigated for Hyup-In in Eoan-Yang area. These ones reveal how Hyup-In worked as laborers and played a role in the agricultural economy in the 18th through 19th centuries. First of all among some interesting issues may be their role, whether they replaced the Nobi(slave) and Kogong as laborers in the farm lands. The uniqueness of this study is 1) that it examines all register records over areas and periods in Eoan-Yang, compared to the previous studies focusing on a record of a specific area or a period in Eoan-Yang due to a difficulty of obtaining data from the register record. 2) This study focuses on the labor role of Hyup-In in a more compact and clearer way by comparing it with roles of Nobi and Kogong in this study period. This have never been tried before in the late Chosun korea history. Contrast to the results of the previous studies, it seems that Hyup-In was not like a slave in status, but a working classes for a host Ju-ho family. They worked for their daily basic needs such as foods and shelters regardless of their status. Their status was mainly the commons, but widely spreaded from the slaves to the elites (yang-ban) in class, and not belonged to any specific status class such as a Nobi. The Hyup-In composed a family and replaced the Nobi as working laborers in the 18th century, However, in the 19th century, they decreased suddenly in population, and their status changed from the commons to the elites. They got older in ages and their family members deceased to one person. These all changes mean that their role as laborers was changed in some reasons, which could not be found yet. It may be due to changes in the system of register record by the government, or to socio-economic changes in the system of the late 19th century.

행위이론을 적용한 도서관 이용자 컨텍스트 정보의 CAbAT 모델링

이정수,남영준,Lee, Jeong-Soo,Nam, Young-Joon 한국도서관정보학회 2012 한국도서관정보학회지 Vol.43 No.1

도서관 이용자의 복잡한 환경과 이용패턴에 따라 생성된 정보는 지식구조화를 통해 이용자에게 적합한 상황인지 정보서비스에 활용된다. 따라서, 도서관 이용자의 다양한 컨텍스트를 정의하고 상호 관련된 컨텍스트의 지식구조화를 위한 컨텍스트 모델 구축이 필수적인 요건이다. 본 연구에서는 컨텍스트의 개념 및 컨텍스트 모델링을 고찰하고, Engestrom의 행위이론의 개념을 활용하여 도서관 이용자의 행위 모델을 1) 주체, 2) 목적, 3) 도구, 4) 노동단위, 5) 커뮤니티, 그리고 6) 규칙으로 설계하였다. 또한, 도서관 이용자의 컨텍스트를 분석하기 위하여 행위정보를 수집하여 그들의 행태를 관찰 및 기록하는 사용자 추적법 (Shadow Tracking)을 활용하였고 수집된 행위정보는 CAbAT(Context Analysis based on Activity Theory)의 방법론을 활용하여 도서관 이용자의 컨텍스트를 설계하였다. The information that has been created according to the complex environment and usage pattern of library user can provide context-aware information service through knowledge structuralization on whether it is a suitable situation for user. Accordingly, the development of a context model for defining the various contexts of library user and for the structuralization of interrelated context information is an essential requirement. This study examined the context concept and context modeling, and utilizing the concept of Activity Theory by Engestrom, the activity model of library user was designed as 1) subject, 2) object, 3) tools, 4) divison of labor, 5) community, and 6) rules. In addition, for the purpose of analyzing the context of library user, activity information was tracked to utilize the Shadow Tracking for observing and recording their forms, and the methodology of CAbAT (Context Analysis based on Activity Theory) was utilized for the collected activity information to analyze the user context model.
