This study examined the networked structure and message types of newspapers advertisements in which universities have put in Daegu and Gyeongbuk provinces in Korea. Data were collected from July to September in 2020. As a result, universities preferred newspapers located in Daegu and Pohang areas. Next, universities have emphasized their cooperations with industries, basic competency capacities, and specialization programs in the advertising messages. When analyzing the findings in terms of university level, key words related to mid- to long-term development plans often appeared in the four-year schools. On the other hand, two or three-year universities frequently used an appeal that emphasized tangible performances. The findings showed the way in which the direction of university newspaper advertisements have been set in line with the rapidly changing environment.

$CO_2$ storage is a very important technology for reduction of greenhouse gas emissions and has been considered as almost the only viable and effective option for immediate large-scale $CO_2$ sequestration. Small-scale demonstration project for offshore $CO_2$ storage in the Pohang Basin is the transitional stage R&D program for technological preparation of large-scale $CO_2$ storage project in Korea. Through the extensive exploration research for prospective $CO_2$ storage sites, the offshore strata in the Pohang Basin was recommended for the storage formation of the small-scale demonstration project. The Pohang Offshore Storage Project launched at 2013, and has accomplished the technical demonstration and technological independence in a wide range of $CO_2$ storage technology, such as geophysical exploration, storage site characterization, storage design, offshore platform construction, injection-well drilling and completion, deployment of injection facility, operation of $CO_2$ injection, and $CO_2$ monitoring. The project successfully carried out $CO_2$ test injection in early 2017, and achieved its final goal for technical development and demonstration of $CO_2$ storage in Korea. The realization of $CO_2$ injection in this project is the measurable result and has been recorded as the first success in Korea. The Pohang Offshore Storage Project has a future plan for the continuous operation of $CO_2$ injection and completion of $CO_2$ monitoring system. The project has provided in-house technical and practical expertises, which will be a solid foundation for the commercial-scale $CO_2$ storage business in Korea. Additionally, the project will help to secure national technical competitiveness in growing international technology market for $CO_2$ storage.

Patinopecten yessoensis is known to be farmed only in the northern part of the East Sea today. In an attempt to extend its production area, we have conducted experiments both in the northern and southern parts of the East Sea and studied on their growth in an aim to use the results for increasing overall productivity of the species. Early juvenile scallops producted in February 2014 showed an average shell length of $0.23{\pm}0.002$. The high growth group showed an average shell length and shell height of $4.11{\pm}0.08mm$ and $4.28{\pm}0.09mm$, respectively, in June while they were $23.63{\pm}3.4mm$ and $24.19{\pm}4.5mm$ in October. The low growth group showed an average shell length and shell height of $2.23{\pm}0.7mm$ and $1.99{\pm}0.9mm$, respectively, in June while they were $1.99{\pm}0.9mm$ and $17.59{\pm}4.5mm$ in October. The daily growth rate of the high growth group was 0.037 mm/day and 0.027 mm/day for the low growth group. In August, we measured the shell length of Patinopecten yessoensis from Yangyang-gun, Gangneung-si, Yeongdeok-gun, and Pohang-si. Patinopecten yessoensis from Pohang-si showed the best growth performance with its shell length of $26.90{\pm}3.6mm$. Patinopecten yessoensis from Yeongdeok was the second largest with its shell length of $23.56{\pm}3.4mm$. We presume that optimal water temperature and phytoplankton abundance of the two regions have contributed to the good growth performance of the species.

The purposes of this study are to evaluate and discuss the importance of geochemical properties of soil materials that play an important role in the occurrence of the landslide, using analyses of microtexture, particle size distribution, XRC, and FE-SEM equipped with energy dispersive spectrum on soils collected from landslide slopes of gneiss, granite and sedimentary rock areas. Soils from gneiss and granite areas where landslides took place have much clay content relative to those from non landslide areas, particularly pronounced in the granite area. Therefore the clay content is considered a sensitive factor on landslide. Clay minerals contained in soils are illite, chlorite, kaolinite and montmorillonite. Especially the content of clay minerals in soils from the Tertiary sedimentary rocks is highest, with abundant montmorillonite as expandable species. It is believed that this area was much vulnerable to landslide comparable to other areas because of its high content of monoorillonite, even though there might be weak precipitation. Since no conspicuous differentiation in mineralogy between the landslide area and non landslide area can be made, the occurrence of landslide may be influenced not by mineralogy, but by local geography and mechanical properties of soils. Geochemical information on weathering properties, mineralogy, and microtexture of soils is helpful to better understand the causes and patterns of landslide, together with engineering geological analyses.

이번 지역건축을 기획하면서, 여러 가지 상념에 잠기게 되었다. 건축에서 지역성이 어느 정도 내재되어 있는지 살펴보고자 하는 것이 혹시 더욱 부정적 결과를 확인하는 것이라면 이를 확인할 필요가 있을지, 또 어떤 긍정적 결과를 확인할 수 있을지, 게다가 여러 개발도상국의 상황과 아시아의 건축적 진행을 보면서, 어쩌면 우리는 더욱 난감한 상황을 보게 될지도 모른다. "건축을 발전시켜온 어떤 민족도 각기 독자적 언어, 복장, 민속이 있는 것처럼, 그들이 좋아하는 형태를 발전시켜왔다. 19세기에 문화의 국경이 붕괴될 때까지 온 세계의 건축에는 지역고유의 형태와 디테일이 있었다. 그리고 어떠한 지역특유의 건물도 사람들의 창조력과 그 지역의 필요성의 결합에 의하여 태어난 아름다운 산물이었다. 그러나 현대 이집트에는 이집트 고유의 토착양식을 찾아볼 수가 없다. 바로 이집트인의 서명이 없다. 그것이 부자들의 집이건 가난한 자의 집이건 무성격하기는 마찬가지이며 이집트인의 자취란 사라져 버렸다."(하산 화티,1973년) 선진국은 스스로 산업혁명을 일으켰고, 이런 사회적 문화적 변동에 적응하기 위하여 1세기 이상의 시간적 여유가 있었다는 것이다. 개발도상국의 급속한 변화에는 건물도 변화의 수단으로 이용되었다는 것이다. "민족적이며, 지역적인 전통이야말로, 새로운 지역주의의 기초로서 보존하고 사용되어야 된다는 '섬세한' 서양의 관찰자들의 탄원은 이같은 상황에서는 전연 고려되지 않았다."고 커티스는 보았다. 섬세한 서양인이 아니라 자국민 스스로 자신의 문명에 대하여 파괴적인 입장에 서 있다면 더욱 난감한 일이다. 지역주의의 의미는 무엇일까? 건축에서 '지역'의 범주는 어디인가? 인종적 분포 또는 민족적 무리를 이름지은 것인가? 아니면 인종과 민족의 공통점인가? 그것도 아니라면 정치적 경계선으로 둘러싸인 경계를 말하는 것인가? 모든 지역이 다 지역주의로 대별될 수 있는가? 어느 곳이 건축에서의 중심지역이며, 또 지역주의는 누가 판별하는가? 프램튼은 문화적인 중심지와 종속적 관계를 지니는 지역주의를 잘못된 구조로 보았다. 근래 10년간 세계적으로 다양한 지역주의가 대두했다. 지역의 개념적, 제도적, 법적인 상태가 어떠한가가 중요한 요인이 된다. 19세기 동안에 유럽사람들이 그들의 정치적 독립을 위한 목적에 활용하기 위하여 부분적으로 거짓된 역사관을 피력했을 때, 유럽지역에서의 지역주의 개념들은 아이리쉬, 까딸로니아, 핀랜드 등을 평가하는 역할이 있었다고 한다. 지역주의를 "감상적인 민족적 편견에서 비롯된 광신적 배타주의"라고 낮추어 바라보는 그로피우스의 시각에 대해, 당당히 맞설 수 있어야 할 것이다. 리꾀르의 말대로 미래에 어떠한 유형의 참된 문화를 유지하는 것은 궁극적으로는 문화나 문명의 단계에서 외래의 영향을 적절하게 하면서 지역문화의 활기찬 형태를 발생시키는 우리 능력에 달려있다. '지역적' 범위는 서구에서 합중국으로 존재하는 경우, 대부분 이질적 문화들의 혼합지역이기 때문이다. 한국과 같이 비교적 단일한 성분의 종족으로 한 국가가 유지된 경우와 미국과 같이 다양한 종족이 모인 경우 등과 비교하면 '지역'이란 이름에 어떤 판단기준이 있어야 할까? 근래 지역적 변동이 적었던 한국의 경우는 상대적으로 재론할 여지가 적다. 그러나 한국의 역사시대 내에서도 확인되지 않은 부분들이 존재하고, 역사시대의 범위를 넘어서 선사시대로 확대하면 '지역'의 개념의 외연적 대상은 더욱 모호해진다.

The occurrence and regional distribution of low temperature and drought during rice cropping period in Korea were studied to characterize the climatic impacts. The long term changes in rice yield, air temperature and precipitation were analyzed, and regional distributions were characterized. The significant climatic impacts on rice yield were heavy rain or flood, drought and low temperature. Since 1910, the occurrence of drought was 29 times, that of flood was 24 times and that of low temperature was 9 times; however, the drought and flood damages were decreased due to expansion of irrigation system since 1970 but low temperature damage was remarkedly increased. The long term changes in air temperature since 1908 in Suweon showed that the 5-year moving average from July to August decreased while that from May to June increased. The occurrence probability of the long term and early term low temperature types were the greatest in Korea and were in order of Suweon, Daegu and Kwangiu. The long term changes in 10-year moving average precipitation from April to June showed a 15 year cycle and recent years were in low precipitation period. The drought frequencies were the highest in Daegu and Pohang area. According to the precipitation from April to June and resevtoir storage at late June, the severest dry area were the Youngnam inland and the southwest coastal area.
