The purpose of this study was to provide basic data needed to establish a system of career education which can offer necessary information for middle school students to select vocational high schools suiting to their talent and aptitude. For this, the study formulated research questions: how middle school students in Gyeonggi-do could acquire information related with entering high school; their level of understanding about general high school and vocational high school and their level of information requirement; real state and effect (level of helping them choose future school) of assistance activity for career education as provided by vocational high schools. For the analysis, the study developed a questionnaire and conducted survey for 4,459 3rd graders from 627 middle schools at Gyeonggi-do. Findings were as follows. First, methods of middle school students getting information related with entering high school turned out in the order of internet search (42.0%), consultation with family and friends (25.5%), consultation with teachers (24.0%). While, their methods of getting information related with entering vocational high school turned out in the order of briefing session by vocational high schools (39.4%), field trip to vocational high schools (24.9%), consultation with teachers from vocational high schools (15.7%). Second, the level of understanding (five points full marks) of Gyeonggi-do middle school students about high school by the type they wished to enter, and the level of information requirement (five points full marks) turned out 3.65 and 3.67 respectively for students who wished to enter general high schools, with the difference being 0.02. On the other hand, the level of understanding and that of information requirement turned out 2.92 and 3.25 respectively with the difference being 0.33, for students who wished to enter vocational high schools. Third, looking at the real state of participation of Gyeonggi-do middle school students in assistance activities for career education provided by vocational high schools, 79.4% of all students were participating. Activity with high participation ratio out of these turned out to be in the order of PR and guide book (booklet, brochure, etc.) for vocational high schools at 90.3%, briefing session prepared by vocational high schools on visit at 87.8% and video of vocational high school PR and introduction at 85.9%. The level of how these activities helped middle school students choose their high school was 3.45, showing more effect by 0.13 on students wishing to enter vocational high schools compared to those wishing to enter general high schools.

Policy concerns related to raising fertility rates are not only common interests among the OECD countries, but they are also issues of great concern to South Korea whose fertility rate is the lowest in the world. The fertility rate in South Korea continues to decline, even though most of the national budget has been spent on measures to address this and many studies have been conducted on the increase in the fertility rates. In this regard, this study aims to verify the effectiveness of the detailed factors affecting the fertility rate that have been discussed in the previous studies on fertility rates, and to investigate the overall trend toward enhancing the quality of life and increasing the fertility rate through macroscopic and structural studies under the recognition of problems related to the policy approaches through the case studies of the European countries. Toward this end, this study investigated if a high quality of life in advanced countries contributes to the increase in the fertility rate, which country serves as a state model that has a high quality of life and a high fertility rate, and what kind of social and policy environment does the country have with regard to childbirth. The analysis of the OECD Better Life Index (BLI) and CIA fertility rate data showed that the countries whose people enjoy a high quality of life do not necessarily have high fertility rates. In addition, under the recognition that a country with a high quality of life and a high birth rate serves as a state model that South Korea should aim for, the social characteristics of Iceland, Ireland, and New Zealand, which turned out to have both a high quality of life and a high fertility rate, were compared with those of Germany, which showed a high quality of life but a low fertility rate. According to the comparison results, the three countries that were mentioned showed higher awareness of gender equality; therefore, the gender wage gap was small. It was also confirmed that the governments of these countries support various policies that promote both parents sharing the care of their children. In Germany, on the other hand, the gender wage gap was large and the fertility rate was low. In a related move, however, the German government has made active efforts to a paradigm shift toward gender equality. The fertility rate increases when the synergy lies in the relationship between parents and children; therefore, awareness about gender equality should be firmly established both at home and in the labor market. For this reason, the government is required to provide support for the childbirth and rearing environment through appropriate family policies, and exert greater efforts to enhance the effectiveness of the relevant systems rather than simply promoting a system construction. Furthermore, it is necessary to help people in making their own childbearing decisions during the process of creating a better society by changing the national goal from 'raising the fertility rate' to 'creating a healthy society made of happy families'

Choi Cheon-yak(about 1684~1755) is an artist who left the various artistic works such as sculptures of royal tombs, architectures. In addition, he was not only a skilled caster but also an able artisan carving jade in the early Joseon Dynasty period. Starting from making royal seals of King Suk-jong, he had made more than about 40 Royal seals until 1755. Choi Cheon-yak was well known as a skilled jade craftsman. Another of his great abilities was to carve subjects into ideal figures. In virtue of his greater abilities, he could take part in the process of constructing Royal tombs and sculpting the stone statues of military officials' which were erected at aristocrats' tombs. With these accumulated skills, when he was in charge of designing the folding screen stones for King In-jo's Jang Neong, he could even replace 12 animals system and clouds with peonies and lotus. Among his various abilities, his skill in carving a sculpture can stand comparison with any other contemporaries. His sculpture skill was at its zenith in 1752, the stone statues of military officials' at the Ui soseson's tomb count his showpiece that describes a model at the age of his late teens and is a realistic and portrayal sculpture, which met the royal family's dignity. In the same year, the stone statues of military officials' constructed by Choi Cheon-yak was elected in front of the Jo Hyen-myeong's tomb(1690~1752). This masterpiece referred to the armor of those of King Gong-min Neong and newly added a helmet and the patterns of a tortoise shell. These patterns of a tortoise shell were passed down to Park Moon-su's tomb in 1756 and Queen Jeong-sung's Hong Neung by his colleagues : Kim Ha-jeong and Byeon Yi-jin etc. He was one of the greatest sculptors in the $18^{th}$ century. People in Joseon praised him highly for his imaginative work from an amorphous object. Especially, these stone statues of military at Jo Hyeonmyeong's tomb shows the proofs of his supreme artwork.

Heterotrimeric kinesin-2 is a molecular motor protein of the kinesin superfamily (KIF) that moves along a microtubule plus-end directed motor protein. It consists of three different motor subunits (KIF3A, KIF3B, and KIF3C) and a kinesin-associated protein 3 (KAP3) that form a heterotrimeric complex. Heterotrimeric kinesin-2 interacts with many different binding proteins through the cargo-binding domain of the KIF3s. The activity of heterotrimeric kinesin-2 is regulated to ensure that the cargo is directed to the right place at the right time. How this regulation occurs, however, remains in question. To identify the regulatory proteins for heterotrimeric kinesin-2, we performed yeast two-hybrid screening and found a specific interaction with creatine kinase B (CKB), which is the brain isoform of cytosolic creatine kinase enzyme. CKB bound to the cargo-binding domain of KIF3A but did not interact with the KIF3B, KIF5B, or KAP3 in the yeast two-hybrid assay. The carboxyl (C)-terminal region of CKB is essential for the interaction with KIF3A. Another protein kinase, CaMKIIa, interacted with KIF3A, but GSK3a did not interact with KIF3A in the yeast two-hybrid assay. KIF3A interacted with GST-CKB-C but not with GSK-CKB-N or GST alone. When co-expressed in HEK-293T cells, CKB co-localized with KIF3A and co-immunoprecipitated with KIF3A and KIF3B but not KIF5B. These results suggest that the CKB-KIF3A interaction may regulate the cargo transport of heterotrimeric kinesin-2 under energy-compromised conditions in cells.

The Ministry of Environment (ME) is planning to adopt in 2020 the IUCN regional Red List for "Guidelines for listing and delisting rare & endangered species and management of endangered Species System". The ME designated 377 species of vascular plants on the regional Red List. In a previous study it had been suggested that 103 species from this list are candidates for the regional Red List. With respect to a possible Red List, we assessed 59 species (after excluding 34 additional NA species and ten endemic species). These assessments indicated that 16 species are at the "threatened" level. Of those, one species is Critically Endangered, ten are Endangered, and five are Vulnerable. A further four species are classified as Near Threatened, 30 as Of Least Concern, and nine as Data Deficient. We found that most of the assessments proposed by the Ministry of Environment were not supported by scientific data, including quantitative geographic data (over 70%) in Criteria B. In order to determine the endangered species belonging to the orchid family, it is necessary to obtain records of illegal activities or data on overcollection. The current problem with the Ministry of Environment Red List has been the lack of management of scientific data on species showing a trend in decreasing population in the mid- to long-term; thus, there is a lack of critical resources for policy-makers. The ME legally designated categories and assessment, and the lack of expertise in failing to comply with the legal law by itself. The key to presenting an accurate overview of the state of Korean flora is to fill the information gaps with respect to significant geographical and taxonomical biases in the quality and quantity of data. By regularly updating the qualified data, we will be able to track the changes in the conservation status of the flora and inform the necessary conservation policies.

The Jongmyo Shrine(宗廟) of Zhou dynasty was a king's main building where a diversity of rituals were held, such as 'the assembly ceremony between a king and vassals in the morning', and was also called as Taechim(太寢) Nochim(路寢) Jeongchim(正寢) and others. Before Zhou dynasty, the expressions of Taesil(太室) and Sesil(世室) were used, and especially the term of Taesil(太室) is found in the records of the early period of West Zhou. In "Seogyeong(書經)", not only the term of Nochim(路寢) but also the letter of 'chim(寢)' itself is not found at all, but the letter of 'sil(室)' appeared several times in the chapters of "Haseo(夏書)" "Sangseo(商書)" "Juseo(周書)" except for that of "Wuseo(虞書)". "Jwajowusa(左祖右社)" meaning that 'the Jongmyo Shrine(宗廟) which keeps the late king's mortuary tablet is established in the left, and Sajikdan altar(社稷壇) which enshrines a god of land and grains is established in the right' was first mentioned in the part of 'Janginyeongguk(匠人營國 : a master craftsman builds different national infrastructures, for instance, a palace and roads)' in "Donggwangogonggi(冬官考工記)" of "Jurye(周禮)". In addition, so-called 'Jwamyowusa(左廟右社)', that is, "Sajik(社稷) enshrining the god of land and grains is built in the right('右'), and the Jongmyo Shrine(宗廟) in the left('左'). (右社稷 左宗廟)" was mentioned as one of different duties of a Sojongbaek(小宗伯) in charge of ancestral rites, which was recorded in "Chungwanjongbaek(春官宗伯)" of "Jurye(周禮)". And it seems that had affected the mention of "Jwajowusa(左祖右社)" in "Donggwangogonggi(冬官考工記)" appeared thereafter. Many manners scholars including Jeonghyun(鄭玄) since Han dynasty interpreted 'Jwa(左 : left)' and 'Wu(右 : right)' here as the arrangement relation of left and right of Jongmyo(宗廟) and Sajik(社稷), but when it is interpreted as "helping(右=佑 : to help) to sacrifice to a god of land and grains in Sajik(社稷), and helping(左=佐 : to help) memorial ceremonies in Jongmyo(宗廟)." it can correspond with a 'Jongbaek(宗伯)''s duties. 'Jeonmyohuchim(前廟後寢)' is the term that began from the expression that "what's in front is called as an jongmyo shrine(宗廟) and what's back as a bedroom.(前曰廟 後曰寢)" in Jeonghyun(鄭玄)'s annotation explaining the chapter of "Hagwansama(夏官司馬)" in "Jurye(周禮)" and "Wolryeong(月令)" in "Yegi(禮記)". Chaeong(蔡邕), a figure in the same age as Jeonghyun(鄭玄), used the expression that "a court is placed in the front, and a bedroom in the back(前有朝 後有寢)." In the paper, two hypotheses were discussed about the theory about Jeonmyohuchim(前廟後寢). In one hypothesis, it expressed two facilities within a wall; 'a court in the front to deal with governmental affairs, and a comfortable interior space in the back.' In another hypothesis, it refers to two independent and separate buildings of 'an jongmyo shrine(宗廟) building in the front as the area of governmental meetings, and the residential building in the back as the residence area with family'.

This paper is about the research on ontology design for a digital archive of seonsaengan(先生案) of the Joseon Period. Seonsaengan is the register of staff officials at each government office, along with their personal information and records of their transfer from one office to another, in addition to their DOBs, family clan, etc. A total of 176 types of registers are known to be kept at libraries and museums in the country. This paper intends to engage in the ontology design of 47 cases of such registers preserved at the Jangseogak Archives of the Academy of Korean Studies (AKS) with a focus on their content and structure including the names of the relevant government offices and posts assumed by the officials, etc. The work for the ontology design was done with a focus on the officials, the offices they belong to, and records about their transfers kept in the registers. The ontology design categorized relevant resources into classes according to the attributes common to the individuals. Each individual has defined a semantic postposition word that can explicitly express the relationship with other individuals. As for the classes, they were divided into eight categories, i.e. registers, figures, offices, official posts, state examination, records, and concepts. For design of relationships and attributes, terms and phrases such as Dublin Core, Europeana Data Mode, CIDOC-CRM, data model for database of those who passed the exam in the past, which are already designed and used, were referred to. Where terms and phrases designed in existing data models are used, the work used Namespace of the relevant data model. The writer defined the relationships where necessary. The designed ontology shows an exemplary implementation of the Myeongneung seonsaengan(明陵先生案). The work gave consideration to expected effects of information entered when a single registered is expanded to plural registers, along with ways to use it. The ontology design is not one made based on the review of all of the 176 registers. The model needs to be improved each time relevant information is obtained. The aim of such efforts is the systematic arrangement of information contained in the registers. It should be remembered that information arranged in this manner may be rearranged with the aid of databases or archives existing currently or to be built in the future. It is expected that the pieces of information entered through the ontology design will be used as data showing how government offices were operated and what their personnel system was like, along with politics, economy, society, and culture of the Joseon Period, in linkage with databases already established.

Weoldae -which we can find inside Joseon palaces- is usually erected in front of important structures including the Main Hall(Jeongjeon, 正殿). There is no clear definition of its nature that we can find in official law codes or dynastic ritual manuals, and such records do not specify what kind of rules should be observed in creating them either. In illustrations of palaces such as and , Weoldae can be seen at structures such as the Main "Jeongjeon" Hall(正殿), Royal office(Pyeonjeon, 便殿), Royal Quarters(Jeongchim, 正寢), Queen's bedroom(Chimjeon, 寢殿), Quarters of the Crown Prince(Dong'gung, 東宮), and other structures. All these structures equipped with a Weoldae were related to special figures inside the royal family such as the king, the queen, the crown prince, and the crown-prince' son. These figures were literally above the law, and as such their treatment could not be defined by law. And these spaces were where they worked or rested while they lived, and where their posthumous tablets(Shinju, 神主) or portraits(Eojin, 御眞) were enshrined after they died. (When such spaces were used for latter purposes, they were designated either as 'Honjeon[魂殿, chamber of the tablet]' or 'Jinjeon[眞殿, hall of portrait']). Joseon was a Confucian dynasty with a strict social stratification system, and the palace structures reflected such atmosphere as well. We can see that structures described with Weoldae in and were structures which were more important than others that did not have a Weoldae. Among structures with Weoldae, the place which hosted most of the dynastic rituals was the Main Hall. In this Main Hall, the King swore an oath himself, passed the incense(香) himself during memorial services, and observed honoring ceremonies[Manbae-rye(望拜禮)] at the "Hwangdan"(皇壇) altar which was built to commemorate the three Ming Emperors. The so-called "Two Palaces[兩闕]" of Joseon shared a unique relationship in terms of their own Weoldae units and the rituals that were held there. In the early half of the Joseon dynasty period, Gyeongbok-gung(景福宮) and Dong'gweol(東闕) constituted the "Two palaces," but after the war with the Japanese in the 1590s during which the Gyeongbok-gung palace was incinerated, Dong'gweol and Seogweol(西闕) came to newly form the "Two palaces" instead. Meanwhile, Changdeok-gung(昌德宮) became the main palace[法宮], replacing the previous one which had been Gyeongbok-gung. In general, when a king moved to another palace, the ancestral tablets in the Honjeon chamber or the portrait in the Jinjeon hall would accompany him as well. Their presence would be established within the new palace. But king Yeongjo was an exception from that practice. Even after he moved to the Gyeong'hi-gung(慶熙宮) palace, he continued to pay visit to the Jinjeon Hall at Changdeok-gung. While he was positioned inside Gyeong'hi-gung, he did not manage the palace with Gyeonghi-gung as its sole center. He tried to manage other palaces like Changdeok-gung and Chang'gyeong-gung(昌慶宮) as well, and as organically as possible.

Recently, we sequenced the entire genome of a freshwater agar-degrading bacterium Cellvibrio sp. KY-GH-1 (KCTC13629BP) to explore genetic information encoding agarases that hydrolyze agarose into monomers 3,6-anhydro-L-galactose (L-AHG) and D-galactose. The KY-GH-1 strain appeared to possess nine β-agarase genes and two α-neoagarobiose hydrolase (α-NABH) genes in a 77-kb agarase gene cluster. Based on these genetic information, the KY-GH-1 strain-caused agarose degradation into L-AHG and D-galactose was predicted to be initiated by both endolytic GH16 and GH86 β-agarases to generate NAOS (NA4/NA6/NA8), and further processed by exolytic GH50 β-agarases to generate NA2, and then terminated by GH117 α-NABHs which degrade NA2 into L-AHG and D-galactose. More recently, by employing E. coli expression system with pET-30a vector we obtained three recombinant His-tagged GH50 family β-agarases (GH50A, GH50B, and GH50C) derived from Cellvibrio sp. KY-GH-1 to compare their enzymatic properties. GH50A β-agarase turned out to have the highest exolytic β-agarase activity among the three GH50 isozymes, catalyzing efficient NA2 production from the substrate (agarose, NAOS or AOS). Additionally, we determined that GH117A α-NABH, but not GH117B α-NABH, could potently degrade NA2 into L-AHG and D-galactose. Sequentially, we examined the enzymatic characteristics of GH50A β-agarase and GH117A α-NABH, and assessed their efficiency for NA2 production from agarose and for production of L-AHG and D-galactose from NA2, respectively. In this review, we describe the benefits of recombinant GH50A β-agarase and GH117A α-NABH originated from Cellvibrio sp. KY-GH-1, which may be useful for the enzymatic hydrolysis of agarose for mass production of L-AHG and D-galactose.

As the information technology industry develops, various kinds of data are being created, and it is now essential to process them and use them in the industry. Analyzing and utilizing various digital data collected online and offline is a necessary process to provide an appropriate experience for customers in the industry. In order to create new businesses, products, and services, it is essential to use customer data collected in various ways to deeply understand potential customers' needs and analyze behavior patterns to capture hidden signals of desire. However, it is true that research using data analysis and UX methodology, which should be conducted in parallel for effective service development, is being conducted separately and that there is a lack of examples of use in the industry. In thiswork, we construct a single process by applying data analysis methods and UX methodologies. This study is important in that it is highly likely to be used because it applies methodologies that are actively used in practice. We conducted a survey on the topic to identify and cluster the associations between factors to establish customer classification and target customers. The research methods are as follows. First, we first conduct a factor, regression analysis to determine the association between factors in the happiness data survey. Groups are grouped according to the survey results and identify the relationship between 34 questions of psychological stability, family life, relational satisfaction, health, economic satisfaction, work satisfaction, daily life satisfaction, and residential environment satisfaction. Second, we classify clusters based on factors affecting happiness and extract the optimal number of clusters. Based on the results, we cross-analyzed the characteristics of each cluster. Third, forservice definition, analysis was conducted by correlating with keywords related to happiness. We leverage keyword analysis of the thumb trend to derive ideas based on the interest and associations of the keyword. We also collected approximately 11,000 news articles based on the top three keywords that are highly related to happiness, then derived issues between keywords through text mining analysis in SAS, and utilized them in defining services after ideas were conceived. Fourth, based on the characteristics identified through data analysis, we selected segmentation and targetingappropriate for service discovery. To this end, the characteristics of the factors were grouped and selected into four groups, and the profile was drawn up and the main target customers were selected. Fifth, based on the characteristics of the main target customers, interviewers were selected and the In-depthinterviews were conducted to discover the causes of happiness, causes of unhappiness, and needs for services. Sixth, we derive customer behavior patterns based on segment results and detailed interviews, and specify the objectives associated with the characteristics. Seventh, a typical persona using qualitative surveys and a persona using data were produced to analyze each characteristic and pros and cons by comparing the two personas. Existing market segmentation classifies customers based on purchasing factors, and UX methodology measures users' behavior variables to establish criteria and redefine users' classification. Utilizing these segment classification methods, applying the process of producinguser classification and persona in UX methodology will be able to utilize them as more accurate customer classification schemes. The significance of this study is summarized in two ways: First, the idea of using data to create a variety of services was linked to the UX methodology used to plan IT services by applying it in the hot topic era. Second, we further enhance user classification by applying segment analysis methods that are not currently used well in UX methodologies. To provide a consistent experience in creating a single service, from large to small, it is necessary to define customers with common goals. To this end, it is necessary to derive persona and persuade various stakeholders. Under these circumstances, designing a consistent experience from beginning to end, through fast and concrete user descriptions, would be a very effective way to produce a successful service.
