C++과 같은 객체 지향 프로그램에서의 소프트웨어 부품 재사용이 소프트웨어 개발의 생산성과 코드 신뢰성면에서 많은 장점을 준다고 알려져 있는 반면, 실제 재사용이 이루어지는 경우는 드문 것이 현실이다. 그러므로 소프트웨어 재사용을 위해서는 사용자의 요구에 맞는 소프트웨어 부품을 제공해 주는 라이브러리 구축이 필수적이라고 할 수 있다. 본 논문에서는 C++클래스 라이브러리 구축을 위한 C++클래스의 부품 추출 및 분류 방법을 제시함으로써 사용자가 쉽게 재사용을 위한 C++클래스를 찾을 수 있도록 하였다, 부품 추출의 경우 특히 클래스의 상속성에 주의하여 속성을 추출하며 클래스 분류는 유사성 함수를 제시하여 함수에 기반한 유사성 값을 통하여 새로운 클래스 계층 구조를 구성할 수 있게 하였다.

화강풍화토의 풍화강도에 따른 중금속 흡착특성을 규명하기 위해 납과 구리를 이용하여 회분식 흡착실험을 수행하였다. 화강풍화토의 풍화가 진행됨에 따라 용해성이 높은 SiO₂, K₂O, Na₂O의 함량은 감소하며, 산화물인 Fe₂O₃의 함량은 증가하는 것으로 나타났으며, 강열감량과 비표면적은 증가하고 투수계수는 감소하는 것으로 나타났다. 화강풍화토의 풍화강도가 증가할수록 비표면적과 점토질 성분이 증가하므로 납과 구리의 흡착량이 증가하는 것으로 나타났다. 화강풍화토에 의한 납과 구리의 흡착속도는 1차 반응속도모델보다 2차 반응속도모델에 의해 적절하게 설명될 수 있는 것으로 나타났다. Effects of weathering intensity on the adsorption of heavy metals such as lead(Pb) and copper(Cu) onto decomposed granite soils were investigated by a series of batch tests. The chemical components such as SiO₂, K₂O and Na₂O having relatively high solubility were reduced and the oxidized Fe₂O₃ content was increased with the increase of weathering intensity. Weathering of granite soils increased the ignition loss and specific surface area, while it decreased the permeability. The lead and copper adsorptions onto the decomposed granites were enhanced with the increase of weathering intensity, mainly due to the increase of specific surface area and clayed contents. Adsorption of lead and copper onto the weathered granites could be more adequately described by the pseudo-second-order kinetic model than the pseudo-first-order model.

The effectiveness of the war procurement plan related to the supply of procurement sources has been raised as a problem. In order to overcome uncertainties in wartime procurement, the military is making various efforts to manage procurement sources, such as supplementing planned documents and contract procedures. In this study, we judged that this source management would affect the overall procurement speed. However, although the effect of these procurement efforts was important, they were mainly emphasized qualitatively, and the quantitatively analyzed research was insufficient. In addition, there have been many studies on the effect of changes in military policy on the supply chain, but most of them analyzed only the effect within one supply chain. Since the military conducts war, the effect of the policy will become clear only when the results of the interaction with the enemy are reflected. To overcome this, we modeled using the lanchester model and system dynamics so that the effect of management appeared as a victory. Also, we applied the Marine Corps oil supply system and produced the following results. First, if the procurement period is reduced, the win rate increases. Second, as fierce battles took place, the effect of shortening the procurement period increased. Third, even if the enemys combat efficiency and stockpile level are higher than ours, it can be overcome by shortening the procurement period. This study is meaningful in that the intangible factor of the procurement source management effort was visualized as the result of the win rate and clearly expressed the effect of the effort by reflecting the results of interaction with the enemy.

It is known that the prediction accuracy for order-shipping time can reduce the inventory burden and logistics costs of private companies. Military is also making various efforts to improve Customer Waiting Time (CWT), that is an elapsed time from order to complete receipt. To ensure efficient military support, CWT is a core performance index in the defense sector. This study attempts to analyze factors affecting CWT, such as inventory holding position, natural environment (inland and island areas), and procurement type, using class 9(Spare parts) demands of Marine units. To this end, key factors are identified by applying regression models and decision tree techniques. As a result, influential factors are whether inventory is held or not, inventory holding position, and regional variables. Authorized Stockage List(ASL) and procurement types are not significant. In this study, among several models, the regression model that considers interaction effects of inventory holding position and regions was the most significant to predict CWT. According to the results of this study, it is necessary to review the selection of current CWT target since it focuses only on whether inventory is held and the type of procurement. The results also suggest to review the validity of selecting ASL items and maintaining inventory levels. In addition, the identified influencing factors and prediction model of CWT will be used to establish effective logistics management policy and improve the reliability of logistics support.

Recently, many automotive parts are replaced with electronic devices. Because of functional requirements for customer convenience, a number of sensor application part is increasing. On the other hand, capacitive sensor technology has made great progress with the development of touch screen of smart phone. And now, many electronic devices begin to use capacitive sensor instead of mechanical switch. Due to capacitive sensor is good durability and it is possible to miniaturize and it can measure proximity and detect human touch, there are various attempts and studies to use capacitive sensor in the automotive part area. Since, the most common cause of sensor incorrect operation is water, this is difficult factor to apply the sensor to automobile exterior parts. In this paper, we propose a integrated capacitive sensing method that uses both self capacitance and mutual capacitance and by using signal pattern obtained by the sensor it shows the possibility to avoid incorrect operation caused by water.

Background: This study aimed to compare job titles of Medical Technologists with international and domestic standard occupational classifications, in order to provide fundamental data for various fields such as job ethics, workplace etiquette, research papers, immigration, employment, translation, university websites, educational evaluation, and unified education systems. Methods: The study conducted a comparative analysis of data from various sources, including the International Standard Classification of Occupations 2008 revision, Korean Standard Classification of Occupations 2017 revision, Standard Occupational Classification 2018 revision, NOC, National Occupational Classification 2011 revision, occupational outlook book, O*NET, and other organizational websites. Results: The study show that Medical Technologists typically received their entry-level education from 2-3 year junior colleges or 4-year universities. The various types of Medical Technologists included clinical laboratory technologists, radiological technologists, physical therapists, occupational therapists, dental technologists, dental hygienists, health information technologists, and opticians. In Korea, there was no standardized English name for Medical Technologists, so caution must be exercised when using official English names. For example, "clinical laboratory technologist" should not be translated as "medical/clinical laboratory scientist" and "health information technologist" should not be translated as "health information manager". Additionally, "optician" should not be translated as "optometrist" as the job skills and level of education required for each job are different. Conclusion: This study is that job titles of Medical Technologists are important for their self-esteem and identity, and therefore it is appropriate to use terms translated based on domestic and international standard occupational classifications.
