This study investigates the complex mechanism of work-family conflict affecting counterproductive behavior of employees based on resource conservation theory and 417 valid samples by using polynomial regression and response surface analysis. Counterproductive work behavior refers to any intentional behavior of an individual that has potential harm to the legitimate interests of the organization or its stakeholders. Results show that first, work-to-family conflict (WFC) and family-to-work conflict (FWC) had four matching types. Compared with "high WFC-low FWC," "low WFC-high FWC" and "low WFC-low FWC" matching conditions, the employee self-control resource depletion and counterproductive work behavior (CWB) are at their highest under "high WFC-high FWC" congruence matching condition. Second, the joint effect of WFC and FWC has a U-shaped relationship with counterproductive behavior. Compared with the "high WFC-low FWC" match state, the level of CWB in the "low WFC-high FWC" match state is higher. Third, the depletion of self-control resources played a mediating role in the effect of WFC on counterproductive behavior. Fourth, emotional intelligence moderated the relationship between the congruence of WFC and FWC and self-control resource depletion. Emotional intelligence was higher, and the positive relationship between the congruence of WFC and FWC and self-control resource depletion was weaker.

본 연구는 경쟁전략이 자원공유에 미치는 영향을 조절하는 요인이 무엇인지를 살펴봄으로써 기존 실증연구에서 경쟁전략과 자원공유 간의 관계가 유의미한 결과를 도출하지 못했던 이유를 찾아내고자 하였다. 이를 위해 경쟁전략이 차별화보다는 저원가를 추구할수록 자원공유의 정도가 높아질 것이라는 가설을 먼저 검증하고, 이후 다각화전략, 상호연결성, 집권화, 자원보유수준을 조절변수로 투입했을 때 경쟁전략과 자원공유의 관계가 어떻게 달라지는지를 분석하였다. 통계결과에 의하면 경쟁전략은 자원공유에 단독으로 유의미한 영향을 미치지 않았으나, 다각화전략을 제외한 상호연결성, 집권화, 자원보유수준과 결합될 때 유의미한 영향을 미치는 것으로 확인되었다. 즉 저원가 전략은 높은 상호연결성, 높은 집권화, 낮은 자원보유수준의 조건 하에서 자원공유를 증가시킨다는 것이다. 이는 경쟁전략과 자원공유의 관계에 대한 기존 논의가 자원공유의 의지나 의도에만 초점을 맞추었던 반면, 능력이나 가능성에 대한 고려가 부족했기 때문인 것으로 설명될 수 있다. 따라서 능력이나 가능성을 반영하는 조절변수의 투입을 통해 자원공유를 보다 잘 예측할 수 있게 되었던 것으로 보인다. 본 연구는 자원공유에 대한 기존 논의의 취약성을 발견하고 보완논리를 제시했다는 점에서 의의를 찾을 수 있다.

The purpose of this study is to examine support policies regarding work and family reconciliation, to suggest plans to improve workplace policies, and to suggest directions for further studies. This study looks at OECD's work-life reconciliation policies as well as family friendly workplace policies in Korea to find a way to enhance business' receptiveness and implementation of the policies. By examining women's labor conditions, this study finds that family friendly workplace policies are necessarily imminent in our society of low fertility and ageing. Along with the evaluation of benefit level and the effectiveness of current policies, this study uses data from interviews with working mothers who have had the experience of family friendly benefits. The results of the analyses suggest that the government should focus on improving the workplace environment in companies that do not show bias against the use of family friendly policies. In order to farm more successful policies, future studies are needed to analyze the changes of fertility, working conditions, support programs, and benefits.

A sensitive concentration method utilising modified gas-purge microsyringe extraction (GP-MSE) was developed. Concentration (reduction in volume) to a microlitre volume was achieved. PAHs were utilised as semivolatile analytes to optimise the various parameters that affect the concentration efficiency. The injection rate and temperature were the key factors that affected the concentration efficiency. An efficient concentration (75.0-96.1%) of PAHs was obtained under the optimised conditions. The method exhibited good reproducibility (RSD values that ranged from 1.5 to 9.0%). The GP-MSE concentration method enhances the volume reduction (concentration factor), leading to a low method detection limit ($0.5-15ngL^{-1}$). Furthermore, this method offers the advantage of small-volume sampling, enabling even the detection of diurnal hourly changes in the concentration of PAHs in ambient air. Utilising this method in combination with GC-MS, the diurnal hourly flux of PAHs from the gas phase of ambient air was measured. Indeed, the proposed technique is a simple, fast, low-cost and environmentally friendly.

A new method is used to estimate the amount of water evaporation from Class A Pan with higher precision and accuracy. The principle of method is to detect the weight change of a buoyant sinker resulting from a change in water level of Class A Pan. A strain-gauge load cell is used to measure the weight change. Field observation of evaporation was done at Pohang Meteorological Station from June 24 to August 4, 2002. By using this new method, it is possible to measure hourly evaporation accurately even under a strong solar radiation and wind disturbance, enabling a direct comparison of evaporation with other meteorological elements. At night, under low humidity and high wind speed conditions, more evaporation was recorded than during daytime. Maximum evaporation rates observed during this period exceed 1.0 mm/hour under the sunny and windy conditions with low humidity. To understand relationships between meteorological elements and latent heat flux at ground level, we suggest intensive held experiments using high accuracy evaporation recording instruments with hourly time interval.

Tidal stream energy extraction remains a site-specific resource due to the "first generation" criteria requiring high-velocity tidal streams. Most studies on tidal energy and turbine blade design heavily focus on installation sites with higher velocity conditions that are non-existent in tropical countries such as the Philippines. To shorten this gap, this review paper tackles tidal turbine design considerations for low-energetic regions such as the tropics. In-depth discussions of operating principles, methods of analysis, and designs of tidal turbine blades are presented. Notable tidal stream projects around the world are also mentioned in the paper. Also, it provides a perspective on the potential of this renewable energy to produce electricity for various sites in the Philippines. Finally, the paper emphasizes the need for new tidal turbine blade designs to be viable in tropical regions, such as the Philippines.

Dehydrins (DHNs) compose a family of intrinsically unstructured proteins that have high water solubility and accumulate during late seed development at low temperature or in water-deficit conditions. They are believed to play a protective role in freezing and drought-tolerance in plants. A full-length cDNA encoding DHN (designated as ClDhn) was isolated from an oriental medicinal plant Codonopsis lanceolata, which has been used widely in Asia for its anticancer and anti-inflammatory properties. The full-length cDNA of ClDhn was 813 bp and contained a 477 bp open reading frame (ORF) encoding a polypeptide of 159 amino acids. Deduced ClDhn protein had high similarities with other plant DHNs. RT-PCR analysis showed that different abiotic stresses such as salt, wounding, chilling and light, triggered a significant induction of ClDhn at different time points within 4-48 hrs post-treatment. This study revealed that ClDhn assisted C. lanceolata in becoming resistant to dehydration.

Relative humidity of air In the greenhouse has to be maintained at 70 to 80 percents to provide a better growth condition of crops. To control relative humidity of air in the greenhouse, a dehumidifier functioning by refrigeration cycle was designed and manufactured in this study. And, results of its performance test in the greenhouse site were reported. The developed dehumidifier has separated condenser and evaporator in the heat exchanger part in order to increase dehumidifying capacity at a low temperature condition. When the conditions of incoming air into the dehumidifier were temperature of $15\~25^{\circ}C$ and relative humidity of $0\~95\%$, quantity of condensed water per hour, ie, dehumidification rate was $4.7\~7.0\;kg/hr$. Relative humidity difference was not greater than 5 percents at various locations in the greenhouse due to proper distributing of dehumidified air through vinyl duct. Thermal energy output from the developed dehumidifier was about 8,5000 kcal/hr that was 7 percents of maximum greenhouse heating load of 10 a.
