The purpose of previous study centered around introducing minerals into bee colonies was to observe the Varrosa destructor mites-repelling effect of minerals ("Pszczelarstwo" 6/2016). The results of research published so far confirmed the purpose of using minerals in the fight against Varrosa infestation. This publication presents partial results of the next stage of research. Using foundation enriched with studied minerals in right proportions leads to diminishing the number of Varroa destructor parasites in bee colonies. It may also contribute to increase in the amount of honey obtained from bees. Foundations with minerals were in most cases correctly filled with larvae, and the new generation of bees didn't show any morphometric or physical-motor aberrations. The effect of minerals in the foundation weakens with time, which requires adequate reaction from the beekeeper. The study showed no negative effect of mineral suspensions added directly to royal jelly of larvae in the swarm cells and worker cells on the development of bees. Additional research was carried out in August and September and led to surprising observations, which are still too early to report. It obliges us to carry out further, extended subject research on a large number of bee colonies in 2017.

In recent years, French courts have decided to adopt an uncompromising stance in the fight against corruption in international arbitration. While French enforcement/annulment courts were originally conducting a limited review of arbitral awards dealing with corruption allegations on international public policy grounds, they now carry a full re-examination of such awards accepting that a corruption plea be raised for the first time before them and admitting new evidence. What is at stake, in terms of international public policy, is to define the happy medium between, on the one hand, the necessity to preserve the enforceability of international arbitral awards, and, the necessity to fight corruption. This paper presents the evolution of French case law in the past years and makes a critical assessment of the French approach by comparison with other jurisdictions.

Efficient crew scheduling for cockpit crew is important in airline industry due to operational safety and cost associated with the flight duty time. Because of complexity of regulations imposed to the cockpit crew. it is complicated to generate an efficient schedule. Schedule of cockpit crew can be generated through two steps; selecting of flight patterns. and scheduling of them to the specific time horizon. Heuristic method is developed and applied with massive data in a limited time of computation. A set of flight patterns is selected from all possible flight patterns. which are generated by composing the flight leg based on regulations. by using the set partitioning problem with objective function of oversea stay cost. The selected set of flight patterns found at the first step is allocated to 4 week crew schedule to minimize the variance of total fight time assigned to each crew. The crew schedules obtained are evaluated and compared with the ones currently used in one of major airline company.

In this work, we formulated a mathematical model for divorce in marriage and extended in to an optimal control model. Firstly, we qualitatively established the model positivity and boundedness. Also we saw sensitivity analysis of the model and identified the positive and negative indices parameters. An optimal control model were developed by incorporating three time dependent control strategies (couple relationship education, reducing getting married too young & consulting separators to renew their marriage) on the deterministic model. The Pontryagin's maximum principle were used for the derivation of necessary conditions of the optimal control problem. Finally, with Newton's forward and backward sweep method numerical simulation were performed on optimality system by considering four integrated strategies. So that we reached to a result that using all three strategies simultaneously (the strategy D) is an optimal control in order to effectively control marriage divorce over a specified period of time. From this we conclude that, policymakers and stakeholders should use the indicated control strategy at a time in order to fight against Divorce in a population.

We used time-of-flight method to analyze transport properties of charge carrier which is produced by X-ray exposure. It is the research of charge transport and specific property of trap that is performed in direct digital x-ray image receptor. But the results shows us different measurement value of electron and charge drift mobility and it is difficult to precise analysis about charge transport properties and trap mechanism. We measured transit time and drift mobility of charge carriers using time-of-flight method to evaluate the correlation of a-Se thickness change and electric field. We made a testing glass with a-Se of 400 ${\mu}m$ thickness on coming glass using thermoevaporation method and built Au electrode with 300nm, $2{\varphi}$ on both sides of a-Se, As a result of this experiment, electron and hole transit time was each $229.17{\mu}s$ and $8.73{\mu}s$ at $10V/{\mu}m$ electric field and Drift mobility was each $0.00174 cm^{2}/V{\cdot}s$, $0.04584cm^{2}/V{\cdot}s$.

이 글은 묵자가 개진한 군사사상들을 살펴보고 그것이 지닌 현대적 가치를 조명해 보는데 있다. 묵자의 군사사상은 그가 제창한 "비공"사상을 이론적 기초로 하여 약자가 강자의 침략과 약탈로부터 자신을 지키고 방어하기 위한 목적으로 형성되었다. 이점은 공격위주의 다른 병법과 다른 점이다. 그런데 묵자의 군사이론 속에는 오늘날 우리가 주목해야할 몇 가지 가치가 눈에 띈다. 먼저, 전쟁 시 부녀자와 노인 그리고 아동에 대해 특별한 임무와 역할을 부여하고 있다는 것이다. 특히 부녀자의 경우는 남자와 거의 동등한 지위를 부여하고 있다. 나라의 비상사태가 발생했을 때 노인과 아동에 대해서도 일정하면서도 중요한 역할을 부여하고 실행하게 하기 위해서는 평상시에도 이들의 사회적 지위를 인정하고 존중해야만 한다. 이처럼 사회적 약자에 대해 권익을 보장하고 지위를 존중할 수 있도록 유도하는 묵가의 사상은 인간이 지닌 권리 존중의 초보적 접근이라고 보여 지며 이 글을 통해 밝혀내고자 한다. 또한 애민의식에서 비롯된 묵가의 과학기술사상은 방어전에도 적용이 되어 당시로 볼 때 상당히 선진화된 무기들을 개발하고 실전에 배치하고 있다. 그런데 묵가가 전쟁에서 활용한 무기들은 모두가 방어전에만 유용한 것들이다. 백성들에게 유용한 것이 진정한 과학이라고 하는 묵가의 사상이 현실에 그대로 적용 사례라고 볼 수 있을 것이다. 지구상에는 크고 작은 전쟁들이 끊이질 않고 발생하고 있다. 이들 전쟁 모두가 자신들만의 이익을 위해 발생하는 것이라는 점을 고려할 때 서로 차별 없는 사랑을 주장한 묵가의 사상이 반전 평화의 군사사상을 주창한 것은 너무나 당연한 귀결일 것이다.
