The germination characteristics of Pseudolysimachion kiusianum var. diamantiacum (Nakai) T.Yamaz., a rare and endemic plant designated by the Korea Forest Service, were investigated according to light conditions, temperature, and pretreatment. As a result of the germination experiment according to light conditions, it was determined that P. kiusianum is a photoblastic seed that does not germinate at all in dark conditions. The optimum germination temperature of the seeds was found to be 20-25℃, considering the final germination rate and germination time. Three growth regulators (IAA, GA₃, kinetin) and two inorganic salts (KNO₃, KCl) were pretreated to improve the germination rate of P. kiusianum seeds. The growth regulators IAA and kinetin had no significant effect on improving the germination rate of P. kiusianum seeds. On the other hand, GA₃ significantly increased the final germination percentage and germination rate regardless of the concentration, especially the treatment of more than 500 mg·L^-1 at 20℃ was more than 4 times more effective than the untreated. The inorganic salts KNO₃ and KCl had no significant effect on the seeds of P. kiusianum at low concentrations, but at higher concentrations (40 mM and 300 mM, respectively), they improved the germination rate and germination age by 2 times compared to the untreated. The results of this study will be useful for the mass propagation of P. kiusianum, which has the potential to be utilized as a native plant for restoration.

Analysis of chemical components in the cultivars of Korean figs(Ficus carical L.), Bongraesi and Seungjung Dauphone were performed. The results of analyses for Bongraesi and Seungjung Dauphine were found out to he moisture content of 88.70, 88.40%, protein 0.70, 0.72%, fat 0.31, 0.27%, fiber 1.12, 0.83%, ash 0.47, 0.44%, pectin 2.81, 2.71% and ascorbic acid 1.33, 1.67 mg%, respectively. The total and reducing sugar contents of two cultivars were 9.0%, 9.6% and 8.5%, 8.8% respectively. Glucose and fructose were major sugar components of figs. The organic acids in figs were mainly composed of citric and tartaric acid. The amino nitrogen contents of the two cultivars were 47.6 mg/100g in Bongraesi and 38.7 mg/100g in Seungjung Dauphine. It was found that major amino acids in figs were serine, aspartic acid, proline and alanine. The content of these fraction in total amino acid were shown 62.8% in Bongraesi and 64.0% in Seungjung Dauphine, respectively.

Gangwon Provincial Office, which is Historical Landmark No. 439, existed from 1395 to 1895. It played a significant role of provincial administration. Gangwon Provincial Office was rebuilt in the $17^{th}$ Century when governors' additional job system began. It had 50 buildings and 670 sections. During the Japanese colonial era and the Korean War, most of the buildings were demolished, and in 2005 partially restored. Currently, after the old Wonju City Post Office was demolished, the back garden facilities of the Provincial Office are being restored. The back garden of Gangwon Provincial Office was completely destroyed when the Japanese army base at Wonju made it a playing field during the Japanese colonial era. After demolishing the old post office in the back garden, excavation and investigation were made. A pond and building relics were found, but they were too damaged to be restored. However, this thesis found that there were Bongraekak, Yeongjusa(Kwanpungkak), Cheyako, Joojeong Rainbow Bridge after studying literature and paintings. There were also Hwansunjeong and Bangjangdae outside the pond. The names of the back garden and how they were made are related to hsien. In the pond, they made 3 islands signifying Mt. Samshin(immortal world) in the legend and built pavilions on that. The pavilions of the back garden were named Bongrae, Yeongju, and Bangjang, and the titles of other pavilions also had the names of hsien. The back garden of Gangwon Provincial Office was made like an immortal world, befitting its role of governing Mt. Bongrae(Mt. Geumgang.) The governors of Gangwon Province often went to the back garden and enjoyed becoming a hsien. They regarded themselves as the owners of Bongrae, i.e., the immortal world. Gangwon Provincial Office has a unique historical significance because it implemented an immortal world, making use of the characteristic of Gangwon Province.

Volcanostratigraphy in Ulleung Island is divided into 4 stratigraphic groups: Dodong Basaltic Rocks, Ulleung Group, Seonginbong Group and NariGroup. The main pyroclastics in them includes lapilli tuff intercalated within the Dodong Basaltic Rocks, lapilli tuff at the top of Sadong Breccia, Sataegam Tuff, Gombawi Welded Tuff, Bongrae Scoria Deposits, Maljandeung Tuff, Nari Scoria Deposits and Jugam Scoria Deposits. Analysing eruption types, The lapilli tuff in the Dodong Basaltic Rocks is derived from Surtseyan eruption, and the Bongrae, Nari and Jugam Scoria Deposits are caused by Strombolian eruptions or/and sub-Plinion eruptions, but the Sataegam Tuff and Maljandeung Tuff are derived from Plinian and phreatoplinian eruptions. Among them the large-scaled eruptions. In particular, the eruptions of Maljandeung were large enough to result in caldera collapse, and had falled out tephras to the eastern Korean peninsula but even Japan Islands. The magma with high potential to be still alive is judged to be trachyandesitic and phonolitic in composition. If the trachyandesitic magma explodes, it will probably result in a strombolian eruption and have a fairly low explosivity, but if the phonolitic magma explodes, it will probably result in a plinian eruption and have a much higher explosivity. If the eruption had a high explosivity, there is a possibility that it could easily be converted into a phreatoplinian eruption due to the influx of groundwater by the easy generation of fractures. These large-scaled eruptions could fall out tephras to the eastern Korean peninsula but even Japan Islands.

This study examines and compares music-related records in the mubo (舞譜; choreography notes) written by Sung Gyeonglin (成慶麟, 1911 - 2008), based on the records of 11 kinds of jeongjae (the music and dance performances at the royal court) found in Lee Byungseong's (李丙星, 1909 - 1960) Changsa and Jungjaecheol (呈才及唱詞綴). Even though these records are personal, they provide valuable information about the mubo of the Iwangjikaakbu (the Royal Music Institute) during the period of Japanese colonization. The eleven kinds types of jeongjae-'Cheoyongmu (處容舞)', 'Hyangryungmu (響鈴舞)', 'Mugo (舞鼓)', 'Bosangmu (寶相舞)', 'Chunangjeon (春鶯?)', 'Gainjeonmokdan (佳人剪牧丹)', 'Suyeonjang (壽延長)', 'Mansumu (萬壽舞)', 'Bongraeeui (鳳來儀)', 'Jangsaengboyeonjimu (長生寶宴之舞)', and 'Musanhyang (舞山香)'-can be largely divided into two types: Dangak (Tang dynasty music) and 'Hyangak (traditional Korean music).' The former is distinguished musically by whether or not the jukganja appears. For the appearance of the jukganja in 'Sujeyongjang', 'Bongraeeui' and 'Jangsaengboyeongjimu', the 'boheojaryung (步虛子令)' was used and given the impressive name of jangchunbullojigok (長春不老之曲).' The term punggyungjigok (豊慶之曲)' was used for music that guides a group dance and dancers. For the latter, hamnyungjigok (咸寧之曲) was performed during the development of the dance, and the pungungyeonghoijigok (風雲慶會之曲) was played at the end of the piece. As for the accompaniment for the jeongjae performed by the Iwangjikaakbu, it is significant that various elaborate names were attached to Sangryungsan, Jungryungsan, Seryungsanm, Garakdeoli, Samhyunhwanip, Yeombulhwanip, and taryung (the traditional Korean ballad), which were all parts of 'Samhyunyoungsanhoesang (靈山會上).' Specifically, the 'Hyangdanggyoju (鄕唐交奏)' in 'Jeongjaemudoholgi' was accompanied by various melodies of the 'Samhyunyoungsanhoesang', which were given extravagant names. These are the personal records of the Iwangjikaakbu mubo that were retained by Lee Honggu (李興九, b. 1940), who owns the 'Hakyeonhwadaehapseolmu.' Among them, the ten kinds of jeongjae found in the notes of Sung Gyeonglin are often referred to as 'mueui (舞儀)' and widely used for research on individual jeongjae performances and the history of their development. The notes of Lee Byungseong have not been investigated thoroughly until now and this is the first study that provides a comparative analysis of the notes of Lee Byungseong and Sung Gyeonglin. This investigation is expected to contribute to the further research and knowledge of the jeongjae performance during the period of Japanese colonization.

Under Article 19, Paragraph 1 of the Food Industry Promotion Act, Rural Development Administration renews the Korean foods composition table every five years. Before the publication of the tenth revision of the Korean foods composition table in 2021, this paper suggests methods for collecting representative samples of 182 highly consumed foods in Korea. Food markets are categorized by their distribution channels, which are supermarkets and local markets. Eight samples are collected from each category by applying the National Food and Nutrient Analysis Program (NFNAP)'s stratified multi-stage sampling. The NFNAP was implemented in 1997 as a collaborative food composition research effort between the National Institute of Health (NIH) and the US Department of Agriculture (USDA) to secure reliable estimates for the nutrient content of food and beverages consumed by the US population. Selected supermarkets for selecting representative food samples are Emart Kayang, Homeplus Siheung, Lottemart Dongducheon, Emart Suwon, Lottemart Dunsan, Lottemart Yeosu, Emart Ulsan, and Hanaroclub Ulsan. Selected local markets also are Doksandongusijang in Geumcheon-gu and Pungnapsijang in Songpa-gu, Seoul, Ilsansijang in Ilsanseo-gu, Goyang, Unamsijang in Buk-gu, Gwangju, Beopdongsijang in Daedeok-gu, Daejeon, Bongnaesijang in Yeongdo-gu and Jwadongjaeraesijang in Haeundae-gu, Busan, and Jungangsijang in Jinhae-gu, Changwon.
