This study conducted a questionnaire survey of 482 male and female second graders in middle schools located in Cheongju, Chungcheongbukdo. This study lays its purpose on establishing the nutrition facts labeling system by understanding eating habits and analyzing the actual state of reading nutrition facts labels and degrees of understanding them among middle school students, and helping them to engage in right food purchasing activities and through it result in developing sound eating habits by providing them with basic material to be employed to actively utilize nutrition facts for choosing and buying healthy foods. As a result of surveying regarding the actual state of reading food labels, regarding degrees of recognition of food labels, it was revealed that 91.1% of female students recognized them, while 42.1% of male students did not recognize them, indicating lower levels of recognition among the male group. Regarding reasons for not checking food labels, 49.2% indicated habitual purchasing, followed by poor contents in the label(20.2%), ununderstandable contents(17.7%), and the lower reliability of the contents(6.9%). As a result of surveying regarding the actual state of reading nutrition facts labels, in recognition of nutrition facts labels, female rather than male students showed higher degrees of recognition, and degrees of recognition were found to differ according to parents' total income and mothers' educational attainments.

This paper presents an UHF(Ultra High Frequency) band small cavity structured RFID(Radio Frequency Identification) tag antenna with a long reading range, designed to apply on metal cart or pallet for auto-parts logistics. The size of tag antennas is $140{\times}60{\times}10mm^3$, attached on a exporting metal cart, and it can give the information of inventory and logistics of carts. By collecting the exported carts and increasing the recovery rate of missing carts or pallets, the paid import tax can be refunded when the carts are returned back to the manufacture. The tag antenna was equipped with a cover to prevent damage, and the dielectric constant of the cover is considered for the simulation. The reading range of the tag antenna is 12 m using LP(Linear Polarization), 10 m with CP(Circular Polarization) reader antennas. This 920 MHz UHF RFID cavity tag ensures the long reading distance of the antenna regardless of the material of the object where it is attached.

The purpose of radiological Dispersal Device(RDD) is to kill people by explosives and to cause radiation exposure by dispersing radioactive materials. And It is a form of explosive that combines radioactive materials such as Co-60 and Ir-192 with improvised explosives. In this study, we tested and evaluated whether it was possible to read the internal structure of an explosive using X-rays in a radioactive explosive situation. The improvised explosive device was manufactured using 2 lb of model TNT explosives, one practice detonator, one 9V battery, and a timer switch in a leather briefcase measuring 41×35×10 cm³. The radioactive material used was the Co-60 source used in the low-level gamma ray irradiation device operated at the Advanced Radiation Research Institute of the Korea Atomic Energy Research Institute. The radiation dose used was gamma ray energy of 1.17 MeV and 1.33 MeV from a Co-60 source of 2208 Ci. The dose rates are divided into 0.5, 1, 2, and 4 Gy/h, and the exposure time was divided into 1, 3, 5, and 10 minutes. Co-60 source was mixed with the manufactured explosive and X-ray image reading was performed. As a result of the experiment, the X-ray image appeared black in all conditions divided by dose rate and time, and it was impossible to confirm the internal structure of the explosive. This is because γ-rays emitted from radioactive explosives have higher energy and stronger penetrating power than X-rays, so it is believed that imaging using X-rays is limited By blackening the film. The results of this study are expected to be used as basic data for research and development of X-ray imaging that can read the internal structure of explosives in radioactive explosive situations.

Lactic acid is an environmentally benign organic acid that could be used as a raw material for biodegradable plastics if it can be inexpensively produced by fermentation. Two genes (ldhL and ldhD) encoding the L-(+) and D-(-) lactate dehydrogenases (L-LDH and D-LDH) were cloned from Lactobacillus sp., RKY2, which is a lactic acid hyper-producing bacterium isolated from Kimchi. Open reading frames of ldhL for and ldhD for the L and D-LDH genes were 962 and 998 bp, respectively. Both the L(+)- and D(-)-LDH proteins showed the highest degree of homology with the L- and D-lactate dehydrogenase genes of Lactobacillus plantarum. The conserved residues in the catalytic activity and substrate binding of both LDHs were identified in both enzymes.

This study presents an Automated Warehouse Management System (AWMS) using a bar-code system The AWMS has been designed to be associated with an Integrated Production Management System (IPMS), which basically includes the following four modules i.e the sales management, production management, material management, and data management. Now, whenever storage or retrieval of the material occurs in the warehouse, the events could be processed quickly and accurately only through reading the 13 digit bar-code including 5 digit position code and simply typing in the number of material. Consequently, the AWMS associated with IPMS could automatically coincide the item counts on document with those in the warehouse. Also, this makes it possible to identify the material quantities in real time.

Michael McKeon, in The Origins of the English Novel, 1600-1740, sets forth a theoretical study of a large canon of seventeenth- and eighteenthcentury works, based upon the dialectic of genre formations, which attempts to analyze certain "instabilities" in generic and social categories- "instabilities" that McKeon identifies as "Questions of Truth" and "Questions of Virtue." In this paper, I argue with McKeon's optimistic reading of Samuel Richardson's work, Clarissa, or The History of Young Lady (1740), which concludes that-unlike Pamela's "manifest material and social empowerment"-Clarissa acquires "manifest discursive and imaginative empowerment" and "wins" (to use McKeon's terms) the "battle" with her antagonist, Robert Lovelace. What is difficult to accept in this reading of Clarissa is McKeon's claim that the "success" of Clarissa's resistance to Lovelace, despite the tragic rape, is evident in her "new-found power" which is represented in the heroine's spiritual "conversion"- her decision to die to protect her "version of truth and virtue." McKeon's spiritual "conversion" not only forces Clarissa to surrender her legal right to prosecute her rapist but also forces her to seek the shelter of her "father's house" in the afterlife because she can no longer "make others accept [her] own version of events as authoritative." Thus, in contrast to McKeon, I claim that Clarissa represents the necessary conditions for its heroine's "empowerment" primarily in language that suggests her manifest social invalidation; language which in particular emphasizes that her rape and torture by Lovelace forces Clarissa's spiritual "conversion" to seek her reward in the afterlife-thereby concluding that Clarissa's discursive and imaginative empowerment does not and cannot exist in the secular, material world.

A thoredoxin (CTRX) gene was cloned and characterized from a full length cDNA library prepared from taproot of three-year old Codonopsis lanceolata. A CTRX was 666 nucleotides long and has an open reading frame of 372 bp with 124 amino acid residues (pI = 4.92). The deduced amino acid sequence of the CTRX matched to the previously reported plant thioredoxin h genes. The deduced amino acid sequence of CTRX exhibited the similarity of 33-67% among previously registered thioredoxin genes. The expression of CTRX in leaves of Codonopsis lanceolata was increased by wounding and 1 mM $H_2O_2$, but decreased by 0.1 mM cadmium.

The concern with scientific mode1s has been growing in science education, and schematic models are frequently used to teach science concepts in secondary schools. The aim of this study is to investigate how well the scientifically gifted students understand scientific concepts through activities of modifying scientific models which we developed. Thirty 8th-grade students participated in the study, 15 in a control group and 15 in an experimental group. For the students in the experimental group, teaching material with activities of modifying models, while for the students in the control group, the teaching material with traditional activities such as explanation, problem solving, and reading. The teaching contents in physics for both groups were linear momentum. We used multiple-choice test and essay-type test to evaluate students' achievements after lessons, and then compared their achievements of both groups. Through the research, we could find a clue that model-modifying activities are helpful for the gifted students to enhance their understanding of physics concepts, although the statistics does not show meaningful difference between experimental and control groups.
