한반도 남동 해안은 중부 동해안의 정동진 지역과 더불어 많은 지형학자들에 의해 해안단구 지형발달에 대한 연구가 이루어져 왔다. 대보에서 방어진에 이르는 해안에서 해안단구는 크게 고위면, 중위면, 저위면으로 나누어지며, 이들은 다시 고위 I (H I)면, 고위II(H II), 중위면, 저위 I(L I)면, 저위II(L II)면으로 세분되었다. 특히 연구지역에서 북북동쪽으로 약 22km 떨어진 경주시 감포읍 대본리와 나아리에서는 고위면보다 더 높은 해발고도에서 고고위 I(HH I)면, 고고위II(HH II)면이 확인되었다(황상일ㆍ정혜경ㆍ윤순옥, 2000).

The existence of coastal terraces, HH(High higher) surfaces found at Gampo of southeast coast and at Jeongdongjin of the central east coast were confirmed at Jjgyeong-Ri, the areal border between Gyeongjuand Ulsan city on the southeast coast of Korea Peninsula. Especially this study reports HH JK-surface located on the 155m a.s.l, which is the highest altitude among the ancient shorelines of the coastal terraces in Korea. The HH surfaces on the study area are classified into HH JK at 155m, HH I at 140m and HH II at 115m, and each formation stage is related to MIS 17(720∼690ka BP), MIS 15(630∼560ka BP) and MIS 13(510∼480ka BP) respectively. The HH-surfaces remain to be larger than those of H- and L-surfaces. The reason is caused by the unique factors of the coastal geology and morphology on the study area during the formation stage. And also the areal difference by the magnitude of upheaval doesn't exist from north to south because the altitude system of ancient shoreline on each coastal terrace is same along the east coast. The upheaval rate of the eastern coastal areas was measured in the relation to the ancient shoreline and formation stage among the coastal terraces such as HH JK-, HH I-, HH II, H I- and H II surface, and was almost same as 0.23mm/y.

This paper is to classify subregions of Yeongnam region, to realize their core area, and to provide the basis on studying inherent cultural characteristics in Yeongnam region. To do so, I made a overlay human factors of administrative district and dialect with physical factors of drainage basin and climate area. The limit of subregion is the range of possessing environmental factors similar to provincial center. The parcels possessing a equivalent combination of environmental factors are 27, the size of parcel is various from one-city/county to six-city/county. These parcels are classified to six subregions(Andong, Sangju, Kyeongju, Daegu, Kimhae, Jinju). The boundary of subregion is high mountains and large river which are obstacle to communication between subregions, and in case of little obstacle exists transitional zone.

As a part of geophysical studies on segmentation of the Ulsan fault, walkaway refraction seismic data were measured at 17 stations near National Road 7 between Kyungju and Ulsan. Seismic anisotropy was analyzed in the offset range of 1-48 m. The average refraction velocity of 1787 m/s indicates the refractor is the upper boundary of weathered basement. P-wave anisotropy is computed to be 0.056 in average, which may serve as a weak evidence that the strike of major geologic structure coincide with the inferred fault direction. In the south of the province boundary between Kyungsangnam-do and Kyungsangbuk-do, the velocity anisotropy is normal in that P-wave velocity in the strike direction is faster than the one measured in the dip direction. On the contrary, it appears that the fault strikes in many directions or that fractures may be developed better in the dip direction in the northern par. Such a difference in anisotropic pattern is believed to be a seismic evidence indicating that a segmentation boundary of the Ulsan fault locates near the province boundary.

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.

In this paper, a Quaternary fault is described, which is developed in the mid-eastern part of Ulsan Fault Zone, near the southern Gaegok-ri, Oedong-eub, Gyeongju, Korea. The Gaegok 6 fault is developed along the contact between Early Tertiary granite and Quaternary gravel deposit overlying unconformably the granite. The fault strikes $N02^{\circ}{\sim}22^{\circ}E$ and dips $45^{\circ}{\sim}80^{\circ}$ to the west. This fault has a 30~50 cm wide cataclastic shear zone with gouge zone, mixed with Quaternary sediments and fault breccia of granite. In the main Quaternary fault plane, the orientation of striation is $17^{\circ}$, $356^{\circ}$, indicating a dextral strike-slip faulting with some normal component. There is another striation ($78^{\circ}$, $278^{\circ}$ and $43^{\circ}$, $270^{\circ}$) with reverse-slip sense, developed on the subsidiary plane which cuts the main Quaternary fault plane. In brief, the fault has been developed between the granite in the western part and the Quaternary gravel deposit in the eastern part. The western block of fault is uplifted. The striations and movement senses of faults indicate multiple compressional stages in this region. The fault has a similar orientation, westward dipping geometric pattern, and reverse sensed kinematic pattern with Gaegok 1 fault developed in the north. Thus, the Gaegok 6 fault is probably a southern extension of Gaegok 1 fault.

The study aims to identify economic interdependencies between regions and define functional economic areas of Korea by analyzing inter-firm transaction networks. Previous research has relied on pre-given administrative boundaries or cultural homogeneity and used data such as commuting, population movement, and cargo flows which could not fully explain economic activities. To overcome the limitations, this study applies a community detection method to inter-firm transaction networks derived from the CRETOP+ database of Korean corporate data. The novel dataset and the network analysis enables us to identify Korea's functional economic areas based on actual inter-firm linkages. The result shows that there are six to seven economic blocs in the networks as of 2018. In particular, one huge economic bloc is formed integrating the Seoul metropolitan area, Chungcheong, and Gangwon provinces. Meanwhile, North Jeolla and South Jeolla provinces form two economic blocs separately rather than being tied up in one bloc due to the low frequency of transactions between each other. The two big economic blocs of Daegu-Gyeongbuk and Busan-Gyeongnam exist, and interestingly, Ulsan, Gyeongju, and Pohang form a separate middle-sized bloc across the administrative boundaries. The results reveal that the future balanced national development policies should be implemented based on functional economic areas derived from empirical data.

Even after the Gyeongju earthquake and the Pohang earthquake, hundreds of aftershocks and micro-earthquakes are still occurring in the southeastern part of the Korean Peninsula. These phenomena mean that the stress is constantly working, implying that another huge earthquake may occur in the future. Therefore, the gravity field interpretation method was used to analyze the deep geological structure of the Pohang-Ulsan region in the southeastern Korean Peninsula. First, a gravity survey was performed to collect the insufficient data and to calculate the detailed Bouguer gravity anomaly in the study area. Based on the gravity anomaly data, the location, direction, and maximum depth of deep fault lines were analyzed using the inversion methods "Curvature analysis" and "Euler deconvolution method". As a result, it is interpreted that at least six fault lines(C1~C6) exist in deep depth. The deep fault line C1 is well correlated to the Yeonil Tectonic Line(YTL), suggesting that YTL is extended up to about 4000m deep. The deep fault line C2 consists of several segment faults and well correlated to the fault lines on the surface. Inferred fault lines C3, C4, and C5 have an NW-SE direction, which is parallel to the Ulsan fault. The deep fault line C6 has the direction of NE-SW, and it is interpreted that the eastern boundary fault of Eoil Basin is extended to the deep. Comparing the inferred fault lines with the distribution of micro-earthquakes, the location of the deep fault line C1 is well correlated to the hypocenter of micro-earthquakes. This implies that faults in deep depth are related to the recent earthquakes in the southeastern Korean Peninsula.
