This work was carried out to investigate the effects of mashing proportion of meju(as wet weight basis of raw soybean) to 20% salt brine on the chemical compositions and sensory characteristics of kanjang. By increasing the salt brine proportion in the kanjang mash, total nitrogen, TCA soluble nitrogen and total free amino acid content in kanjang were decreased accordingly, but although pH values and organic acids content were not different noticeably, the major organic acids in kanjang, lactic acid, pyroglutamic acid and acetic acid were increased up to the mashing proportion of 1:2 from 1:1 and pH values decreased up to that of 1:2.5. Residual sugar content in 1:1 kanjang was exceptionally high. The major free amino acids in kanjang were glutamic acid, lysine, alanine and leucine. The acceptability scores of kanjang tested by sensory evaluation were decreased in inverse proportion to the salt brine proportion of kanjang mash, but those of kanjang samples with $1:1{\sim}1:2.5$ mashing proportions were not significantly different but that of 1:3 different from 1:1 statistically at 5% level. The major chemical compositions, significantly effective to the acceptability of kanjang, were found to be glutamic acid and free amino acid by statistical analysis.

Recently, the incidence of disasters and safety incidents is increasing rapidly, and the interest and demands of the people are increasing. In particular, traffic accidents in Korea are decreasing due to the continuous efforts of the government and the local governments, but still higher than the OECD average. In response to such demands of the times, the 'Regional Safety Index', a numerical value that quantifies the level of safety of each local government, is being publicized every year to awaken public awareness. The Regional Safety Index covers seven categories of accidents (traffic accidents, crimes, suicide, infectious diseases, fire, safety accidents, and natural disasters) in local governments. But, this study focuses on the traffic accident area and analyzed. The target local government is Ulju county of Ulsan Metropolitan City. Based on the traffic accident statistical data of Ulju county, the analysis of the traffic accidents and vulnerable points were analyzed. Among them, 3 key improvement districts were selected and 15 vulnerable branches were selected for each key improvement district. Next, we prepared measures for improvement of each accident vulnerable site through analysis of geographic information through traffic data related to traffic accidents and interview with related organizations. In addition, the improvement measures are divided into the structural infrastructure improvement, the institutional improvement, and the traffic safety culture movement from the viewpoint of traffic accident prevention. Finally, the implications of this study are to clarify the duties and roles of the relevant departments in the municipality, based on the implementation schedule of the improvement projects for the prevention of traffic accidents and the budget plan. In addition, it is very important that the participating agencies involved in traffic accidents and the private sector participate in the project.

Recently, the problems in school violence did not stop on the crime between the members at the school and which developed into the invasion crime of the school caused by outsiders. The school is no more the safety zone from the crime. Particularly, in the case of the elementary school, because there are nearly no people who oppose to the outside attacker and can control this, it is the place where it is vulnerable to the invasion crime. The Metropolis of Seoul implements the School Sheriff system within the jurisdiction bureau, in the public elementary school. However, actually the School Sheriff business is being managed, never applying a rule in the Security Industry Law with the main content, that is the Security Industry Law application is excluded. Because the jurisdiction on the contract of Seoul City and operating company are run, the various issues is caused. First, since it is not being considered as a security business, the commercial liability insurance for security company has no chance to applicate when the operation company and the School Sheriff have related damage generation. So the security for the indemnification of loss of the victim is weak. Second, The task of the School Sheriff is ruled just by in the individual contracts. But it is insufficient with this thing. The related duties are required some supplement like a general rule application including the obligation of the guard in the security industry law. Third, the education of the School Sheriff needs to connect with the educational programme in the security industry law. The related professional education specially needed for the prevention of school violence ought to be reserved compensation. Forth, the citizens still demand the strengthening of police patrol for the surroundings of a school in spite of the result of Seoul City's public survey. Therefore, the active relation of cooperation with the police needs to be supported legally and institutionally with the Security Industry Law application. Fifthly, the success of the School Sheriff business can be more guaranteed with the supervision of the legal and institutional device like a the Security Industry Law application or police and all sorts of administrative execution's and etc.

This study was conducted to examine the possibility of complete lodging. prevention, the growth and yield of the paddy rice plant by paciobutrazol 0.6%G application at 15 days before heading under the several levels (0, 5, 10, 15, 20, 25, 30, 35, 40, 45 kg/10a) of nitrogen fertilizer in 1986. Culm length was shortened 10-15% by paclobutrazol application. The shortened rate of internode was very extreme on the 3rd and 4th internode in paclobutrazol application. Moment the height of center gravity and lodging index turned higher with increasing nitrogen fertilizer, on the other hand, those of paclobutrazol application were smaller than control. Lodging degree (0~4) was 1~3 above 25kg/10a level of nitrogen fertilizer in control, however, no more than 1 at 45kg/10a level of nitrogen fertilizer in paclobutrazol application. Ripened grain ratio and grain weight of paclobutrazol application were larger than those of control. Yield increased more 15-26% in paclobutrazol application than control. The nitrogen level of maximum yield was about 25kg/10a in control, but was 31kg/10a in paclobutrazol application.

Effects of gamma-irradiation of 1 to 10 kGy on the microbial growth, contents of amino acids, fatty acids, and free sugars, and changes in acid values in soybean powder were studied. Irradiation doses at $3{\sim}5\;kGy$ inhibited the mold growth completely in two kinds of imported soybean powders. Contents of sulfur-containing amino acids, such as cysteine, in both soybean powders decreased with irradiation, whereas no significant changes in free amino acid and fatty acid contents of both soybean powders were observed. Free sugar contents of stachyose and sucrose in Chinese soybean powder decreased with increasing irradiation dose level, whereas, those of other sugars remained unchanged. Results of this study confirm that $3{\sim}5\;kGy$ irradiation can be safely applied to apply to soybean powder without causing significant quality deteriorations microbiologically and chemically.

GOCI-II, succeeding the mission of GOCI, was launched in February 2020 and has been in regular operation since October 2020. Korea Institute of Ocean Science and Technology (KIOST) processes and produces in real time Level-1B and 26 Level-2 outputs, which then are provided by Korea Hydrographic and Oceanographic Agency (KHOA). We introduced current status of regular GOCI-II operation and showed future improvement. Basic GOCI-II products including chlorophyll-a, total suspended materials, and colored dissolved organic matter concentration, are induced by OC4 and YOC algorithms, which were described in detail. For the full disk (FD), imaging schedule was established considering solar zenith angle and sun glint during the in-orbital test, but improved by further considering satellite zenith angle. The number of slots satisfying the condition 'Best Ocean' significantly increased from 15 to 78. GOCI-II calibration requirements were presented based on that by European Space Agency (ESA) and candidate fixed locations for calibrating local observation area were. The quality management of FD uses research ships and overseas bases of KIOST, but it is necessary to establish an international calibration/validation network. These results are expected to enhance the understanding of users for output processing and help establish detailed plans for future quality management tasks.

It is noted that generally speaking, the expressing of actualization or non-actualization of events is not the main role of possibility for the utilization of expressions. In spite of this fact, it is possible to see many examples in which possibility expressions represent actual events, and impossibility expressions represent a type of non-actualization in relation to events. This effect can be described as a semantic extension, by which the participant-internal possibility is extended to actualization due to participant-internal factors, and the participant-external possibility is extended to the actualization due to participant-external factors. When the related possibility expressions are used in this extended sense, they express the dynamic evaluative meaning of 'desirability' of the realized event, while it is determined that when the impossibility expressions are used in this extended sense, they are seen to express the evaluative meaning of 'regretfulness' about the non-actualization of the event. In Modern Japanese, it is noted that there are a few expressions of ability and possibility. They can be largely divided into four types of expressions, according to their origins or uses of expression, which are 'ability verbs', affixes '-れる/られる(-reru/rareru)', '-できる(-dekiru)', and '-得る(-eru)'. They can all express participant-internal possibility and participant-external non-deontic possibility. While 'ability verbs', affixes '-れる/られる' and '-できる' can express participant-external deontic possibility, '-得る' cannot. However, '-得る' is the only possible element to designate the event of a epistemic possibility. Also, the four types of expressions have the usage of conveying 'actualization/non-actualization,' as is the case of the Korean language. However in Japanese, in fact adjectives cannot be associated with 'ability verbs' or 'ability affixes.' Thus the expressions of 'regrets' should in that case depend on the use contexts, unlike the expression 'adj+-지 못하다' as noted in Korean. The ability and possibility in Modern Chinese are mainly expressed by means of the four auxiliary verbs '能($n{\acute{e}}ng$)', '会(huì)', '可以(kěyǐ)' and '可能 ($k{\check{e}}n{\acute{e}}ng$)'. '能' and '会' along with '可以' can all convey participant-internal possibility. In this way '能' and '可以' can express participant-external possibility. Only '会' and '可能' can express epistemic possibility. As for 'actualization,' among the four auxiliary verbs, only '能' can represent actualization. Also, among the negatives of the four auxiliary verbs, only '沒能' can represent non-actualization.

The safety and security of food supply should be one of the primary responsibilities of any government. Estimation of nation's food commodity intakes is important to control the potential risks in food systems since food hazards are often associated with quality and safety of food commodities. The food intake databases provided by Korea National Health and Nutrition Examination Survey (KNHANES) are good resources to estimate the demographic data of intakes of various food commodities. A limitation of the KNHANES databases, however, is that the food intakes surveyed are not based on commodities but ingredients and their mixtures. In this study, reasonable calculation strategies were applied to convert the food intakes of the ingredients mixtures from the KNHANES into food commodity intakes. For example, Perilla leaf consumed with meat, raw fish, and etc. in Korean diets was used to estimate its Korean intakes and develop algorithms for demographic analysis. Koreans have consumed raw, blanched, steamed, and canned perilla leaf products. The average daily intakes of the perilla leaf were analyzed demographically, for examples, the intakes by gender, age, and etc. The average daily intakes of total perilla leaf were 2.03${\pm}$0.27 g in 1998, 2.11${\pm}$0.26 g in 2001, 2.29${\pm}$0.27 g in 2005, 2.75${\pm}$0.35 g in 2007, and 2.27${\pm}$0.20 g in 2008. Generally, people equal to or over 20 years of age have shown higher perilla leaf intakes than people below 20. This study would be contributed to the estimation of intakes of possible chemical contaminants such as residual pesticides and subsequent analysis for their potential risk.

This study analyzes the current work of the traditional theater around 'Back Parkcheomji(season2)' of theatre troupe 'Saninomou'. 'Back Parkcheomji(season2)' has proved that it is possible modernization while at the same time preserving the traditional theater. As a result, 'Back Parkcheomji(season2)' regained the spirit of contemporary social criticism and reality inherent in Kokdugaksinorum. The performance are beyond the traditional production method, which has created a new performance aspects. 'Back Parkcheomji(season2)' has created the puppets like this 'Kimga' 'Seweolho' 'Ryukbang' 'Chourani'. Traditional and creative dolls has criticized our modern society at the same stage. On the other hand, plays such as tightrope, Pungmul, Burna confirmed the spirit of Namsadangpae, and gave a dramatic fun. 'Back Parkcheomji(season2)' has dual stage. The dual stage will produce a magnificent spectacle, and has provided a variety of attractions. 'Back Parkcheomji(season2)' re-created the traditional theater of Namsadangpae in vivid contemporary version. The performance has made the opportunity to think again about the value of classical and allowed to recognize the new phase of classical theater.

Securing a range of wheat resources is of particular importance with respect to wheat breeding, as it provides a broad genetic foundation. Although wheat breeders have used different wheat germplasms as material resources in current breeding systems, the traits of most germplasms collected from foreign countries differ from the unique traits that have evolved in the Korean environment. In this study, conducted over a 2-year period (2018 and 2019), we therefore evaluated the agricultural traits 1,967 wheat germplasms collected not only in Korea but also worldwide. During the period from sowing to February, the average temperature in 2019 was greater than 1℃, whereas from March to June, the average temperature was approximately 0.9℃ higher in 2018. Compared with the growth recorded in 2018, the stem length in 2019 increased by approximately 20 cm in 2019, and there were notable differences heading date and maturation between 2018 and 2019. In 2019, the heading dates of 973 and 713 wheat resources were earlier and later than those in 2018, respectively. Moreover, stem length was found to be highly correlated with the heading date and maturation. In Korea, where the rainy season and tine of rice transplantation overlap with the time of wheat harvest, early flowering time with high grain yield has been the most important selection target with respect to wheat breeding. We anticipate that the findings of this study will provide would use a foundation for the selection of elite materials and the development of resource core-sets for Korean wheat breeding programs.
