The purpose of this study is to examine the implications of religious activities to longevity in a perspective of religious people in the ancient near east. The major sources of the study are the records of Adad-Guppi in the Neo-Babylonian Empire, prayers of Daniel in the Old Testament and records of Anna in the New Testament. The research method is a synchronic method based on final forms of the texts. Adad-Guppi lived for 104 years with temple-centered lives, fasting-like dedication, prayer and mission for the nation. Daniel fasted and prayed for the return of Jewish nation, and restoration of the city and the temple in Jerusalem, resulting in longevity of late eighties in the court of Babylon. Anna lived for more than 100 years old with her life mission for the messiah in spite of limitations of her times as an old widow. The implications of religious activities with temple-centered lives, fasting, prayer, and mission for the ages are understood to be beneficial to longevity in a perspective of the ancient near east.

Road conditions which obstruct the driver from seeing road markings, such as in the evening or in the rain, due to the lack of a light source gives way to increasing the risk of traffic accidents. In order to increase road safety, the Korea Expressway Corporation set up a pilot project which used high-quality materials along a section of the Gyeongbu Expressway between Daejeon and Pangyo. There is little research on high-quality materials in the field of pavement marking. This study introduces high-quality materials used in pavement materials, presents the results of a survey conducted to examine the effect of the pilot project and analyzes traffic accident data from before and after the implementation of the pilot project. The survey results show that 87% of the respondents were highly satisfied with the pilot project. With the goal of evaluating the effect of the pilot project, this study used traffic accident data provided by the Korea Expressway Corporation accident data and performed a before-after study of the number of traffic. The results of data analysis show that there were 62 and 48 traffic accidents before and after the implementation of the pilot project. In addition, the result of Emperical Bayes Method indicates that there is an 41.7% decrease in the number of traffic accidents as an effect of High-quality Pavement Marking Materials.

Traditionally, the larvae of Allomyrina dichotoma (AD), a species of the rhinoceros beetle, have been widely used for their antidiabetic, antihepatofibrotic, antineoplastic, and antiobesity effects. The United Nations' Food and Agriculture Organization has reported on the possibility of using edible insects in human dietary supplements in the future. However, despite the growing interest in insect-based bio-active products, the biological activities of these products have rarely been studied. Previously, we reported that AD larvae inhibit the in vitro differentiation of adipocytes via transcription factor downregulation. In this study, our objective was to evaluate the effects of a hot-water extract of AD larvae on allergy and inflammation. To investigate the inhibitory effect of the extract on allergic reactions, we measured the levels of ${\beta}-hexosaminidase$, tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin-4 (IL-4), and cyclooxygenase-2 (COX-2) after activation of RBL-2H3 cells using Compound 48/80. In addition, the inhibitory effect of the extract on inflammation was determined using Raw 264.7 cells after lipopolysaccharide (LPS) stimulation. The extract significantly inhibited the ${\beta}-hexosaminidase$, $TNF-{\alpha}$, IL-4, and COX-2 levels in RBL-2H3 cells. Furthermore, it effectively inhibited the inflammatory cytokine IL-6, nitric oxide, and inducible nitric oxide synthase expression in LPS-stimulated Raw 264.7 cells. These results suggest that AD larval extract can be potentially developed as an antiallergic and anti-inflammatory therapeutic agent.

The insect industry is a promising agricultural resource and expected to grow steadily. In Korea, Gryllus bimaculatus and the larvae of Tenebrio molior, Protaetia brevitarsis, and Allomyrina dichotoma were listed as general food ingredients. As interest in these edible insects increases, rearing techniques and nutritious food sources are needed for mass production. In this study, wheat bran, dog feed, and pig feed were investigated for their effects on the larval growth of P. brevitarsis and A. dichotoma. When fermented sawdust with 30% wheat bran was used, the larval survival rate of P. brevitarsis and A. dichotoma (p=0.244341 and p=0.007966, respectively) and growth rate (p=0.001400 and p=0.000051, respectively) were significantly lower than those of the control (fermented sawdust with no supplement). Therefore, fermented sawdust with a high density of wheat bran was inappropriate for both insects. When fed fermented sawdust with 2.5 or 5% of dog and pig feed, the survival rate and growth rate of the larvae were higher than those of the control. Interestingly, the maximum larval weight with 2.5% dog feed was increased by $3.35{\pm}0.10g$ and $32.59{\pm}0.79g$ for P. brevitarsis and A. dichotoma, respectively. In addition, the larval period of both was shorter than that of the control by 40 days or more. Therefore, it is considered that animal feed can be used as a feed source for these edible insects.

Edible insects are reported to be rich in protein, minerals and vitamins, and much attention has been paid to them as a future food source. In Korea, they were massively reared and sold. In order to enhance the market value of edible insects for industrialized mass production, it is important to develop the safe and nutritious feed sources for rearing them are needed. In this study, a chlorella-free control feed (Exp1) and six experimental feeds supplemented with 0.5~2.0% liquid or powder types of chlorella were formulated. Protaetia brevitarsis and Allomyrina dichotoma, registered as food ingredients in Korea, were fed with the designed feeds and parameters of growth including larval survivorship, larval body weight, and larval period were analyzed. When chlorella added, larval survivorship was increased 2~13%(p>0.05) and 9~22%(p<0.05) in each beetle compared to the control. Interestingly, the larval period of chlorella powder-added groups was shortened by 24 days (Exp3, p<0.05) in P. brevitarsis and 19 days (Exp4, p<0.01) in A. dichotoma. Meanwhile, some parameters, crude protein, crude fiber, copper, zinc, potassium, magnesium, and phosphorous, in chlorella-added groups of P. brevitarsis were also higher than the control group. Therefore, chlorella could promote the larval growth performance of these two beetles and be used as a feed additive in rearing them.

This study aimed to determine of water quantity in pot for water flooding culture of Pinus thunbergii Parl., Chaenomeles japonica Lindl. ex Spach and Osmanthus fragrans Lour. The survival rate of P. thunbergii Parl. and C. japonica Lindl. ex Spach in the water quantity in pot 60% or 40% was 100% and the rate of O. fragrans Lour. in the 60% or 40% water was 90.0% or 93.3%. However the survival rate of the 100% water was less than 90% in P. thunbergii Parl, C. japonica Lindl. ex Spach and less than 60% was in O. fragrans Lour. The increasing rate of plant height for P. thunbergii Parl. in the water quantity in pot 40% or 60% was above 50%, and the C. japonica Lindl. ex Spach or O. fragrans Lour. was above 90%. However the increasing rate of plant height in the water 100% was less then the others as a 38.2%, 65.4% or 66.7% in respectively in P. thunbergii Parl., C. japonica Lindl. ex Spach and O. fragrans Lour. The increasing rate for leaf number for P. thunbergii Parl. in the water quantity 40% or 60% was above 80%, and the C. japonica Lindl. ex Spach or O. fragrans Lour. was above 70%, however the 100% water was below 60% in all treatment. Therefore, the survival rates in some woody plants of the 40% or 60% water in the pot was above 90% and the plant growth of plant height, plant width, leaf number or fresh weight was proper increased. But the survival rates and growth of the 100% water in the pot was decreased
