This study analyzed the educational background, career, and post-retirement activities of notable bureaucrats employed at Chosun Railway Bureau during the Japanese colonial period in Korea. First, significantly, most railway bureaucrats were of Japanese origin, being specialized in railway operations and adjusted to occupation in a reserved organizational environment for a considerable time period. Second, the Japanese showed explicit eagerness to work at the Chosun Railway, which fitted their ideology of railway bureaucrats. In addition, almost 60% of the bureaucrat population had strong educational experience from Tokyo Imperial University, which is equal to the percentage of graduates from other institutions operating during the Japanese colonial period. Moreover, in the very early period of building the railway system, the demand for specialists was higher than for other jobs and divisions because of the railroad's complex infrastructure, which resulted in high job appointment rates. In a similar sense, based on a strong affiliation of bureaucrats with railways, the number of bureaucrats from Japanese Railway Worker's Bureau was higher initially because of bureaucrats from South Manchurian Railway Company. These changes essentially contributed to alteration of bureaucrats' awareness and created a more positive attitude regarding the Chosun Railway. In the meantime, as opposed to the Taiwan and Manchurian Railways, both Chosun Railway and the Taiwan Railway were operated in compliance with strong bureaucratic traditions.

Soybean [Glycine max (L.) Merr.] seed is an important dietary source of protein, oil, carbohydrates, isoflavones, and other nutrients for humans and animals. But, antinutritional factors in the raw mature soybean are exist. Kunitz trypsin inhibitor (KTI) protein and stachyose are main antinutritional factors in soybean seed. The genetic removal of the antinutritional factors will improve the nutritional value of soybean seed. The objective of this research was to breed a new yellow soybean strains (rs2rs2titi genotype) with the traits of lacking of KTI protein and low content of stachyose. Breeding population was developed from the cross of "Jinyangkong" and 15G1 parents. Presence or absence of KTI protein was detected based on Western Blot technique. Content of stachyose in mature seed was detected by HPLC. Total four new strains (603-1, 603-2, 625, and 694) with KTI protein free and low content of stachyose were selected. Four strains (603-1, 603-2, 625, and 694) have yellow seed coat and hilum. Plant height of 603-1 strain was 65 cm and 100-seed weight was 29.2 g. Plant height of 603-2 strain was 66 cm and 100-seed weight was 26.2 g. Plant height of 625 strain was 64 cm and 100-seed weight was 27.1 g. Content of stachyose for four new strains was 3.0~3.50 g/kg. Four strains selected in this research will be used to improve new yellow soybean cultivar with KTI protein free, and low content of stachyose.

Pakistan is a South Asian auspicious developing country. Based on the corruption perception index report 2020 by transparency international, Pakistan has ranked 124 with total scores of 31 globally and 188 ranks with a score of -2.25 in terms of political stability ranging from 0 (lowest) to 100 (highest). More crucially, the inflow of foreign direct investment toward Pakistan has declined between 2008 and 2019. Though political instability and government corruption have both positive and negative linear relationships with foreign direct investment, we tested the moderating impact of government corruption between political instability and inward foreign direct investment over time. We also tested the relationship between political instability and inward foreign direct investment in different phases of political regimes in the same country. Our results suggested that authoritarian regimes attracted more inward foreign direct investment than that during democratic periods of government. Furthermore, we found that there was low inward foreign direct investment when government corruption was high in the country. However, government corruption weakened the positive relationship between political instability and inward foreign direct investment (FDI).

This study is aimed to figure out the way Yoon Hee-sun perceived the real situations of the society under the Japanese ruling and responded to overcome difficulties in the process of anti-Japanese independence movement. Yoon Hee-sun played an important role as a female activist of the righteous army movement in Kangweon-do and Manchuria. She was a daughter-in-law of Yu Hong-seok, wife of Yu Jae-won, and mother of Yu Don-sang. Three generations of her family had taken the lead in anti-Japanese independence movement. The Yus belonged to a school of 'Hwaseo' and devoted their lives to the independent movement based on the thought of 'wijung chuksa sasang', which means 'defending orthodoxy and rejecting heterodoxy'. They desired to go back to the past and recover as it was rather than building a new society. Therefore, their fights against Japan's invasion were not for establishing a modern nation-state but for recovering the royal authority of the existing order. Both her maiden home and her in-laws belonged to a school of 'Hwaseo' and Yoon Hee-sun couldn't go out of the boundary of her family background. Also, the motivation of her participation in the righteous army movement was based on the confucian values such as loyalty to the king, filial piety and fidelity. In particular, she possessed a high level of self-awareness not only as a wife but also as a woman. On the basis of this, she faced up to reality. For the more effective way of revolt against Japan's invasion, she determined to change the perception of women identified only as a wife of somebody. She thought her duty was to enlighten women through 'education'. As a result, manifestoes and songs supporting the righteous army movement were used as a powerful method.

Since the signing of the Korea-Europe Free Trade Agreement, the volume of trade transactions between South Korea and Europe has increased. The traditional single-mode transport system has been transformed into an intermodal transport system using two or more modes of transport. In addition, the conventional sea and air transport routes have been restricted, leading to a decline in Korean exports to Europe, and the rail transport mode is becoming mainstream in the market due to the influence of COVID-19. This paper focuses on the China-Railway Express to explore a new intermodal transport route from Korea to Europe. First, the fuzzy analytic hierarchy process (AHP) is used to evaluate the factor weights when selecting intermodal transport routes from Korea to Europe. Then, the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method is used to rank three alternatives. The results show that among the four factors (total cost, total time, transportation capability, and service reliability), the total cost is the most significant factor, followed by the total time, service reliability, and transportation capability. Furthermore, the alternative route 1 (Incheon-Dalian-Manchuria-Hamburg) is preferred.

The flora of Oesorak in the Soraksan National Park including Chombongsan(Mountain) and Kwanmobong(Peak) were surveyed from February to August, 1996. These areas have very rich and diverse flora;620 taxa with 89 families, 321 genera, 526 species, 2 subspecies, 89 varieties and 3 forms in the Oesorak, 404 taxa with 251 genera, 350 species, 1 subspecies, 51 varieties and 2 forms in the Chombongsan(Mountain), 286 taxa with 206 genera, 233 species, 1 subspecies, 50 varieties and 2 forms in Kwanmobong(peak). The Oesorak had very distinct floristic characteristics such as the wild habitats of Asarum maculatum(Aristolochiaceae) and Ilex macropoda(Aquifoliaceae). In the phyorgeographical point of view, the six species such as Sapium japonicum (Euphorbiaceae), Euphorbia joldini(Euphorbiaceae), Ilex macropoda (Aquifoliaceae), Styrax japonica (Styracaceae), Carex sideros ticta (Cyperaceae) and Asarum maculatum (Aristolochiaceae) were naturalized into this region, while the 17 taxa such as Abies neprolepis(Pinaceae), Pinus pumila(Pinaceae), Thuja koraiensis(Cupressaceae), Allium senescens(Liliaceae), Lilium distichum(Liliaceae), Saxifraga punctata(Saxfragaceae), Rosa marretii(Rosaceae), Bupleurum euphorbioides(Umbelliferae), Androsace cortusaefolia (Primulaceae), Peducularis mandshurica(Scrophulariaceae) and Leontopodium coreanum (Compositae) were distrivuted to this region. The colonizing weedy species such as Ixris repens (Compositae) were distributed to this region. The colonizing weedy species losa(Labiatae) and Rosa rugosa(Rosaceae) were naturalized into ca. 900m at sea level mainly due to the sand soil from the seashore. Mountain roadbed is susceptible than other areas to the slippery road problems, due largely to snow and rain, particularly during winter. Sand soils from seashore are utilized to minimize this slip in traffic operation.

In 2007, according to the records, I made an on-the-spot survey of the place where Doju Cho Jeongsan and his family might have lived in exile in Manchuria and released a paper in which I decided that the site could be the Shuidongchun (village) of Luotongshanzhen in Liuhexian, Jilin Province. Thereafter, sponsored by the Doju Cho Jeongsan's Memorial Project from 2008 to 2013, many times, I carried out the field investigations and researches on Liuhexian, including the visits of the institutions which have the historical documents, in order to find the data related to the participation of him and his family in the anti-Japanese movement. I was, hence, able to reconfirm that the village had been the place of their exile, based on my collected data and the oral reports which the local historians and ethnic Korean elders had provided. In this study, using the historical documents and maps and the oral materials, I made an attempt to prove the historical truth thoroughly once again. First, the existing sources of Doju Cho and his family's settling in Manchuria from March 1909 to 1917, were carefully analyzed which were described in The Jin-gyeong. In doing so, the misspelling of the names and the spatio-temporal errors of the people's activities were corrected. Next, I researched on another town, Shuitungou of Liuhexian in Fengtian Province (in West Gando of Manchuria), which it is known that Doju and his family stayed in, and the Laogushan (mountain), which it is believed that Doju cultivated himself in. Finally, through the attempt, I reached the conclusion that Doju and his family had settled at Shuidongchun (once called Shuidonggou or Shuitongchun) of Luotongshanzhen (once called Datonggou) in Liuhexian, Jilin Province. In the Liuhexian-related documents and maps published in the eras of Republican China and Manchuria, the place name called Shuitungou was not found. However, I discovered a map in the era of Republican China on which Shuitongchun was recorded as Shuidonggou. In addition, considering the administration system of Republic China, tun(屯) and gou(溝) could not be used together in the place names. Accordingly, Shuitungou was more likely misspelled as Korean people in those days mispronounced Shuidonggou. Furthermore, people in China has habitually called the Dagushan(大孤山), located in the north of Gushanzizhen of Liuhexian, as the Laogushan(老孤山). This means that the Korean people who lived in the area then perhaps recorded the mountain as the Nogosan(老姑山), the mountain of the old goddess, according to Korean enunciation, because they had the custom of worshipping the mountain goddess. I tried my best to find the historical documents regarding Doju and his family's anti-Japanese activities to prove the location of exile in which they settled in northeastern China (Manchuria). However, I was not able to reach the initial goal completely due to the shortage of objective evidences, only to leave tasks to be solved. I hope that this study can give a little help to researchers who are interested in this matter.

On the musical stage in 2019, there were many works depicting the Japanese colonial period. This is due to 2019 the timeliness of the March 1st Movement and the centennial of the establishment of the Provisional Government of the Republic of Korea. The way of remembering and commemorating historical facts reflects the power relationship between memory subjects and the time, namely the politics of memory. Until now, stage dramas dealing with the era of Japanese rule have focused on the commemoration of modern national and national defense, including feelings of misfortune and respect for patriots. This study analyzed the metaphor of the memorials emphasized to the audience in the commemorative musicals Shingheung Military School, Ku: Songs of the Goblin, and Watch which were performed in 2019, and looked at how to adjust memories and memorials. The above works highlight the narratives of ordinary people as well as those recorded against the backdrop of the Manchurian Independence Movement and Hongkou Park, expanding the object of the commemoration. Through this, active armed resistance efforts, self-reflection and reflection were highlighted. The case of Shingheung Military School revealed the earnestness of ordinary people who led the independence movement through the movement of central figures. Ku: Songs of the Goblin revises memories by reproducing forgotten objects and apologizing through time slip. Watch has strengthened the spectacles of facilities through documentary techniques such as photography, news reels, and newspaper articles, but it also reveals limitations limited to records. In the 3.1 Movement and the 100th anniversary of the establishment of the Provisional Government of the Republic of Korea, devices that actively reveal that the "people's movement" is connected to the present. To this end, the official records reflected the newly produced values and memories and devoted themselves to the daily lives and emotions of the crowd. In addition, both empirical consideration and calligraphy were utilized to increase reliability. These attempts are meaningful in that they have achieved the achievement of forming contemporary empathy.

One hundred Sixty two quadrats were sampled from natural forests, in Kangwon-do and Kyungsangbuk-do. On the basis of Mueller-Dombois & Ellenberg method, field survey, which accounts for the characters of the species structure of Pinus densiflora community and Quercus mongolica community, was carried out between 1991 and 1994. To analyze the data, CCA ordination and D.B.H, analysis were used. 1. DBH analysis showed that Pinus densiflora community is likely replacing Quercus mongolica or Quercus variabilis community. DBH analysis also showed that Quercus mongolica - Lindera obtusiloba community balances among the Quercus mongolica, Fraxinus rhynchophylla, and Tilia amurensid in the canopy, and that Quercus mongolica-Abies nephrolepis community, mixed forest balances among the Quercus mongolica, Pinus koraiensis, and Abies nephrolepis in the canopy. In general, Quercus mongolica seems to remain as a dominant species. 2. A certain correlation seems to exist between nutrients types and Pinus densiflora community. Quercus mongolica prefered to grow in the medium elevation area that has medium level of total nitrogen, organic matter, and C.E.C. Pinus densiflora, Quercus serrata and Quercus variabilis were found in the low elevation area that has low level of total nitrogen, organic matter, and C.E.C. 3. There seemed to be a certain correlation between nutrients types and Quercus mongolica community. Quercus mongolica and Acer pseudosieboldianum was distributed in the slope area that has medium level of $Mg^{{+}{+}}$, $Ca^{{+}{+}}$, and C.E.C., while Abies nephrolepis, Taxus cuspidata and Pinus koraiensis in the high elevation and ridge area that has low level of $Mg^{{+}{+}}$, $Ca^{{+}{+}}$, and C.E.C. Carpinus laxiflora and Abies holophylla were found in the medium elevation area that has medium level of $Mg^{{+}{+}}$, $Ca^{{+}{+}}$, and C.E.C., while Kalopanax pious, Carpinus cordata and Acer truncatum in the moderately moist and valley area that has high level of $Mg^{{+}{+}}$, $Ca^{{+}{+}}$, and C.E.C. Pinus densiflora and Fraxinus rhynchophylla seemed to prefer the slightly dry, low elevation and ridge area.

In this study, the atmospheric vertical structure (AVS) associated with summertime (June, July, and August) heavy rainfall in Seoul was classified into three patterns (Loaded Gun: L, Inverted V: IV, and Thin Tube: TT) using rawinsonde soundings launched at Osan from 2009 to 2018. The characteristics of classified AVS and precipitation property were analyzed. Occurrence frequencies in each type were 34.7% (TT-type), 20.4% (IV-type), 20.4% (LG-type), and 24.5% (Other-type), respectively. The mean value of Convective Available Potential Energy (1131.1 J kg^-1) for LG-types and Storm Relative Helicity (357.6 ㎡s^-2) for TT-types was about 2 times higher than that of other types, which seems to be the difference in the mechanism of convection at the low level atmosphere. The composited synoptic fields in all cases showed a pattern that warm and humid southwesterly wind flows into the Korean Peninsula. In the cases of TT-type, the low pressure center (at 850 hPa) was followed by the trough in upper-level (at 500 hPa) as the typical pattern of a low pressure deepening. The TT-type was strongly influenced by the low level jet (at 850 hPa), showing a pattern of connecting the upper- and low-level jets. The result of analysis indicated that precipitation was intensified in the first half of all types. IV-type precipitation induced by thermal instability tended to last for a short term period with strong precipitation intensity, while TT-type by mechanical instability showed weak precipitation over a long term period.
