It can be assumed that the reasons why the animation characters, 'Olaf (in Frozen Kingdom)' and 'Minions (in Super Bad)', etc., which were very successful in the merchandising market while having won the popularity better than the main characters are very popular even though such characters appeared only by playing a funny role while assisting the adventures of the main characters are not only because of their cute appearances but also because such characters have their own core features in their inner world as the transitional object-characters. Simply expressing, a 'Transitional Object' as a concept suggested by a child psychologist, 'Donald Winnicott', means a lovey doll or an imaginary friend which temporarily replaces an infant's mother during the procedure when the infant is mentally separated from its mother. However, in case that the theory of transitional objects was applied directly to many narrative content characters for doing a study, there must have been done some studies in advance for establishing some new criteria and indexes related to the transitional object-characters of such narrative contents. Accordingly, while thinking that the 'emotional relationship' between a growth-subject and a growth mediator must be dealt with as the most important content in order to define a transitional object-character in a narration clearly, this researcher established some emotional index for judging the propensities of a transitional object-character on the basis of such way of thinking. The index is composed of 4 kinds of emotional roles (quasi-family member, growth mediator, lovey doll, an imaginary friend), 6 kinds of emotional supports (hugging, protecting, accepting, giving the initiative, improving the relationship and mutual supervising) and 4 kinds of emotional impressions (impression by contacting, impression to protect and impression accepting an attack). In case that some main characters of a family feature animation, 'Inside Out', are analyzed while the index mentioned above is applied, it was found that 'Bing Bong' and 'Sadness' have a high propensity as a transitional object-character. Especially, it could be inversely inferred in which ways some good transitional object-characters can help the narrations on growth of a family feature animation by taking a look at the character, 'Sadness' that has the highest propensity as a transitional object-character. The transitional object-character, 'Sadness' assists the narration on growth internally and externally by helping the internal maturity of a growth-subject in a way of projecting the tasks for the internal maturity of a growth-subject while helping the growth-subject to be successfully externally in a way of providing the growth-subject with some kinds of facilitating emotion. As the results from this Study, since such kinds of emotional experiences provided by such transitional object-characters are displaced to not only the relevant growth-subjects but also the audience who are emphasized with such growth-subjects as they are, such transitional object-characters play a role of hidden benefactors who induce some immersion into the narrations and provide child and adult audience with various layers of emotional satisfaction.

Nitrogen ion implantation and ion plating techniques were applied for improvement of the wear resistance of metallic implant materials. In this work, the wear dissolution behaviour of a nitrogen ion implanted super stainless steel (S.S.S, 22Cr-20Ni-6Mo-0.25N) was compared with those of S.S.S, 316L SS and TiN coated 316L SS. The amounts of Cr and Ni ions worn-out from the specimens were Investigated using an electrothermal atomic absorption spectrometry. Furthermore, the Ti(Grade 2) disks were coated with TiN, ZrN and TiCN by use of low temperature arc vapor deposition and the wear resistance of the coating layers was compared with that of titanium. The chemical compositions of the nitrogen ion implanted and nitride coated layers were examined with a scanting auger electron spectroscopy. It wat observed that the metal ions released from the nitrogen ion implanted S.S.S surface were significantly reduced. From the results obtained, it was shown that the nitrogen ion implanted zone obtained with 100 KeV ion energy was easily removed within 200,000 revolutions from a wear dissolution testing under a similar load condition when applied to artificial hip joint. The remarkable improvement in wear resistance weir confirmed by the nitrides coated Ti materials and the wear properties differ greatly according to the chemical composition of the coating layers. for specimens with the same coating thickness of about 3$\mu\textrm{m}$, TiCN coated Ti showed the highest wear resistance. However, after removing the coating layers, the wear rates of all nitrides coated Ti reverted to their normal rates of below 10,000 revolutions from Ti-disk-on-disk wear testing under the same load condition. From the results obtained, it is suggested that the insufficient depth of the 100 Kel N$\^$＋/ ion implanted zone and of the nitrides coated layers of 3$\mu\textrm{m}$ are subject to restriction when used as frictional parts of load bearing implants.

The velocity horizontal response spectra using the observed ground motions from the recent 5 macro earthquakes, equal to or larger than 4.8 in magnitude, around Korean Peninsula were analysed and then were compared to the acceleration horizontal response spectra, seismic design response spectra (Reg Guide 1.60), applied to the domestic nuclear power plants, and finally the Korean Standard Design Response Spectrum for general structures and buildings. 102 velocity horizontal ground motions, including NS and EW components, were used for velocity horizontal response spectra and then normalized with respect to the peak velocity value of each ground motion. First, the results showed that velocity horizontal response spectra have larger values at the range of medium natural period, but acceleration horizontal response spectra have larger values at the range of short natural periods. Secondly, the results also showed that velocity horizontal response spectra exceed Reg. Guide 1.60 for longer natural periods bands less than 6-7 Hz. Finally, the results were also compared to the Korean Standard Response Spectrum for the 3 different soil types(SC, SD, and SE soil type) and showed that velocity horizontal response spectra revealed much higher values for the frequency bands below 1.5(SC), 2.0(SD), and 3.0(SE) seconds, respectively, than the Korean Standard Response Spectrum. The results suggest that the fact that acceleration, velocity, and displacement horizontal response spectra have larger values at the range of short, medium, and long natural periods, respectively, can be applied consistently to those form domestic ground motion, especially, the velocity ground motion. Information on response spectrum at such medium range periods can be very important since the domestic design of buildings and structures emphasizes recently medium and long natural periods than short one due to increased super high-rise buildings.

The occurrence, distribution, and hydrogeochemical characteristics of uranium and radon in groundwater within different lithologies in Gyeongnam and Gyeongbuk provinces were investigated. A total of 201 groundwater samples from sedimentary rocks taking a large portion of the geology and from igneous rocks taking a small portion of the geology were analyzed and examined using factor analysis. Their radionuclide levels were used to construct detailed concentration maps. The groundwater types, defined using a Piper diagram, are mainly Ca-$HCO_3$ with less Na-$HCO_3$. Among the samples, one site exceeds $30{\mu}g/L$ of uranium (i.e., the maximum contaminant level of the USEPA) and three sites exceed 4,000 pCi/L of radon (i.e., the alternative maximum contaminant level). No samples were found to exceed the 15 pCi/L level of gross alpha or the 5 pCi/L level of radium. The concentration of uranium ranges from 0.02 to $53.7{\mu}g/L$, with a mean of $1.56{\mu}g/L$, a median of $0.47{\mu}g/L$, and a standard deviation of $4.3{\mu}g/L$. The mean concentrations of uranium for the different geological units increase in the following order: Shindong Group, Granites, Hayang Group, Yucheon Group, and Tertiary sedimentary rocks. The concentration of radon ranges from 2 to 8,740 pCi/L, with an mean of 754 pCi/L, a median of 510 pCi/L, and a standard deviation of 907 pCi/L. The mean radon concentrations for the investigated geological units increase in the following order: Granites, Yucheon Group, Tertiary sedimentary rocks, Hayang Group and Shindong Group. According to the factor analysis for each geological unit, uranium and radon behave independently of each other with no specific correlation. However, radionuclides show close relationships with some components. Regional investigations of radionuclides throughout the country require an integrated approach that considers the main lithological units as well as administrative districts.

The nutritional composition and optimal eating stage of the super mealworm, Zophobas atratus (Coleoptera : Tenebrionidae), were investigated to explore its use as a food ingredient. It was determined that 10^th instar larvae were most suitable for eating in terms of nutritional value as well as economic aspects. To improve the quality of powder production, the nutritional value of 10^th instar larvae before and after degreasing was analyzed. After drying the larvae powder, crude protein was the most abundant nutrient both before (52.3%) and after (60.6%) degreasing while crude fat measured 36.3% and 21.7% before and after degreasing, respectively. In terms of essential amino acids, leucine levels were highest and 1.3 times greater after degreasing (4.5%) than before (3.5%). Oleic acid, the highest unsaturated fatty acid in larvae, was 31.7% after degreasing which was 1.1 times higher than before (33.2%). Among various major minerals, potassium was most abundant and 1.4 times higher after degreasing (1267.0 mg/100 g) than before (879.3 mg/100 g). Harmful substances were 1.3 to 2.0 times lower in the degreased larvae, although mercury or pathogenic bacteria were not detected in either group. We therefore conclude that degreased Z. atratus larvae are more suitable for eating than before degreasing.

The following matters were confirmed through the analysis of casualties due to fires in Korea, Japan, and the U.S. in this paper. 1 Korean statistics are not the most detailed of the three countries about casualties due to fires, so we need to have detailed statistics of them on casualties more. 2. Korean deaths are the lowest by 10-11 people due to fires per one million of population. Those of Japan are 15-17 and about 12 people in the U.S.; decreased about 2/3 only for a quarter of a century. 3. Korean deaths are on the decrease about 1.5 people per 100 cases due to fires,3.5 in Japan and 0.2-0.3 in the U.S. Likewise, Korean injuries are on the decrease per 100 cases due to fires From 14.9 in 1977 to 5.1 in 2001 and 5.3 in 2002. In the U.S., the figure was 1.0-1.6. but after the year 1994, it was 1.2 or so. It tends to some increase to 2.6-2.8 in Japan. Therefore, when fires are happened, the death probability is the highest in Japan and 15 times higher than that of the U.S. The injury probability is the highest in Korea and 5 times higher than that of the U.S. 4. Fire deaths rate is the highest in the U.S. about $80\%$ due to home fires (including apartments) among all deaths. Japan tends to decrease of $55\%$. Recently, in case of Korea. it is similar level to that of Japan. 5. Korean aged people of 65 years old and over exceeded by $7\%$ in 2000 and entered an aging society, so It Is time to Investigate and take effect policies to reduce the death of the aged . Japan has ahead a super-aged society that exceeds $20\%$ of the people over the age 65, and many of them die of fire. Consequently, Japan has taken effect policies to reduce deaths from 10 years or more than before. Therefore, it is a good proposal to analyze the policies of Japan deeply and study introduction of them.

This study was performed to evaluate the effect of yam (Diocorea japonica) extract by methanol on sausage quality during cold storage. Yam extracts were prepared by 70% methanol and concentrated using rotary evaporation. The total phenol contents of the extracts were 123.03 mg/g. 1,1'-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and super oxide dismutase (SOD) activity of the extracts were increased with dose dependently. Nitrite scavenging activity was also increased with the increase of concentration of yam extracts; in particular, 70 ${\mu}g/mL$ of the extracts showed 57.12% of nitrite scavenging activity. Sausages containing yam extracts showed lower pH than that of the control. In color, the lightness ($L^*$) of sausages with 1.0% of the yam extracts was lower than that of the control. Redness and yellowness of the sausages with 1.0% of the yam extracts were higher than those of the control. Thiobarbituric acid reactive substances (TBARS) value of the sausage with 1.0% of the extracts was lower than those of the control on days 9 and 12. However, the hardness of the sausage was increased with an increase in yam extracts. From these results, the yam extracts showed high antioxidant activity; moreover, it also retards the lipid oxidation of the sausages during cold storage. The yam extracts could be used as additives to prevent lipid oxidation of the sausage. Further study should be conducted in order to identify the optimum concentration of the extracts in meat products.

This study was conducted to investigate the phytotoxicity of main rice varieties and control efficacy of HPPD inhibitor to major paddy weeds at the time of temperature rise due to climate change. Phytotoxicity of herbicide to rice was increased as temperature was increased, and more severe in root than shoot. The phytotoxicity of japonica rice cultivars for the rice were mild enough to recover. However, glutinous rice, super high yield rice, and Tongil rice varieties were damaged enough to decrease the yield. Shindongjinbyeo transplanted by June 15, showed phytotoxicity enough to recover. However, in the rice field on June 30 and on July 15, the rice showed a remarkable inhibition. The control effect of Monochoria vaginalis and Scirpus juncoides was more than 90% under the temperature condition controlled artificially. However, Echinochloa oryzicola was controlled 40% at $27.5^{\circ}C$, which is a high temperature condition. In rice fields with different transplanting times, annual weeds except for E. oryzicola were highly controlled by 90% or more regardless of the time of transplanting.

The objective of this experiment is to study the possibility of lactate dehydrogenase(LDH) enzyme to prevent lactate accumulation in the rumen, For understanding capacity of bacterial LDH in rumen environments, this study was conducted to explore the effects of temperature, pH, VFAs and metal ions on Lactobacillus sp. FFy111-1's LDH activity, and the LDH activation in rumen fluid accumulated lactate. The optimum pH and temperature of LDH were pH 7.5 and 40$^{\circ}C$, respectively. The LDH activity had a good thennostability at range from 30 to 50$^{\circ}C$. The highest pH stability of the enzyme was at ranges from pH 7.0 to 8.0 and the enzyme activities showed above 64% level of non-treated one at pH 6.0 and 6.5. The LDH was inactivated by VFAs treatments but was enhanced by metal ion treatments without NaCl and $CuSO_4$ Especially, the LDH activity was increased to 127% and 124% of its original activity by 2 mM of $BaCl_2$ and $MnSO_4$, addition, respectively. When the acidic rumen fluid was treated by LDH enzyme of Lactobacillus sp. FFy111-1, the lactate concentration in the rumen fluid was lower compared with non-treated rumen fluid(P<0.05). This lactate reduction was resulted from an action of LDH. It was proved by result of purified D,L-LDH addition that showed the lowest lactate concentration among the treatments(P<0.05). Although further investigation of microbial LDH and ruminal lactate is needed, these findings suggest that the bacterial LDH has the potential capability to decrease the lactate accumulated in an acidic rumen fluid. Also, screening of super LDH producing bacteria and technical development for improving enzyme activity in rumen environment are essential keys for practical application.

We aimed to analyze the microbiological quality of the ready-to-eat (RTE) side dishes collected from traditional markets, supermarkets, and cafeterias in Gyeonggi-do in 2019. A total of 108 samples were analyzed for total aerobic bacterial counts, coliforms and foodborne pathogens depending on place of purchase and cooking methods. Results show that Bacillus cereus was detected in 14 (12.9%) out of 108 samples of side dishes, while no other foodborne pathogens were detected. The mean detected level (range) of total aerobic bacteria depending on place of purchase was 5.8 log CFU/g (3.0 to 8.2 log CFU/g) for traditional markets, 4.3 log CFU/g (2.4 to 7.8 log CFU/g) for supermarkets, and 3.80 log CFU/g (0.0 to 6.8 log CFU/g) for cafeterias, indicating that there was a significant (P<0.05) difference in total aerobic bacterial counts among places of purchase. Among the samples, the highest counts of total aerobic bacteria and coliforms were detected in saengchae (raw vegetables), followed by namul (seasoned herbs, vegetables), bokkeum (stir-fried foods), and jorim (foods cooked in soy sauce). The growth of total aerobic bacteria in seasoned soybean sprouts was inhibited when the sprouts were stored at 4℃ up to 24 h, whereas bacteria rapidly grew at 20 and 35℃ after 3 and 6 h, respectively. These results reveal that storage temperature might play a significant role for the microbiological quality of seasoned soybean sprouts when they are sold in markets. Thus, this study suggests that RTE side dishes should be stored at refrigerated temperature when being sold at markets as well as after purchasing to improve their microbiological quality.
