The inner gate(The last gate inside a temple, facing the main hall) is not a well-known part in the temple construction of Joseon. This study is focused on seeking truth about the inner gate arrangement of the existing temples as well as proving that it has changed while maintaining a certain relationship with the gate-pavilion arrangement. The inner gate is related to the Cheondo ritual which is letting the dead people's spirits go to heaven, mainly performed in Buddhism, and it has been demonstrated that the inner gate has gradually disappeared as the importance of gate-pavilions has been emphasized along with the changes of the ritual. The inner gate was a common construction before the 18th Century but since that time, it has gradually disappeared and finally it faced the main hall as the gate-pavilion and made the 4 halls-centered arrangement with the temple dormitories on both sides.

In inner harbour of Inchon Port, there are two lock gates (50KT, 10KT) which have two gates per lock gate in inner/outer sides except a gate in inner harbour side 7f 10KT. Due to the lack of the fore-mentioned gate, the use of 10KT lock gate Is suspended in every 3 years for regular maintenance. Now an additional gate is under construction in order to improve the efficiency of the 10KT lock gate. This paper will be aimed to evaluate the operational utilization levels of lock gates in present and future. The present operational utilization levels of lock gates are 0.2119 in 10KT lock gate, 0.2051 in 50KT lock gate which were considered the 46.5 closed days every 3 years for 10KT regular maintenance. The levels are estimated to 0.2246(10KT), 0.2539(50KT) in 2006 and 0.2241(10KT), 0.2560(50KT) in 2011. The levels of 50KT lock gate are evaluated to be more rapidly increased up to 24.5% in 2011.

This paper aims at the comparative study of practicing Buddhism and Taoism related to "life gate". The term "life gate", as a physiological entity of disputed morphological identity, first appears in The Inner Canon where it refers to the eyes. Reference to a "life gate" as an internal organ body first appears in The Classic of Difficult Issues which states, "The two kidneys are not both kidneys' The left one is the kidney, and the right is the life gate." Successive scholars refers to life gate as a gi point of Taoists.. The question of the life gate invited little discussion until the Myeong and Cheong Dynasty, when various different theories were put forward. Especially Jin Sa-taek says "life gate" is the governor of the twelve place in the human body, throwing light on the meaning of it. Not that life gate denotes a local point, it does a system of life gate. Generally speaking, life gate designates cinnabar field. I think that the human body produces essence by way of life gate. That is, the human body is unified by the system of life gate. Life gate is not only the source of infusing the engine of the human body with vital energy but also as well as gi-point.

Analyzing the tide data taken at Kunsan inner and Outer ports, non-tidal and mean sea level and harmonic constants of major constituents are investigated to examine the effects of the dyke gate operation on the sea level change in Keum River estuary. Non-tidal and annual mean sea levels decrease at Kunsan Inner and Outer ports after the dyke gate operation, especially showing an abrupt drop of non-tidal sea level at Kunsan Inner port. This non-tidal sea level drop results in the mean sea level gradient change between the inner and outer port, which can be mainly explained in terms of the decrease of river discharge from the dyke. Amplitudes of the $M_2$ and $S_2$ tides at the Inner port increase after the dyke gate operation, showing an abrupt jump, and phases of both tides slightly decrease. Amplitude and phase of the $K_1$ and $O_1$ tides show slight changes after the dyke gate operation. This significant change of semi diurnal tide amplitude is believed as a result of superposition of incident tidal wave and reflected tidal wave from the dyke.

In this paper, we proposed an algorithm to solve the problem that can't maintain hop synchronization using only early-late gate tracking loop due to the drift of geo-stationary satellite in frequency hopping satellite communication system. When the signal is transferred to downlink through DRT(Dehop-Rebop Transponder), the problem with synchronization loss is occurred periodically when using only early-late gate tracking loop, because of energy loss in each side portion of hop due to orbital variation of the satellite. To solve this problem, we have developed Anti-Shrink synchronization tracking algorithm which uses the prediction value of transmission timing and the structure of inner-outer gate instead of early-late gate with the ranging information. Through simulations, we showed that the performance of the Anti-Shrink algorithm is better than that of simple inner-outer energy ratio algorithm and similar to that of conventional early-late tracking loop algorithm with ranging information. No synchronization failure in the proposed algorithm was occurred because of less energy loss and robustness without the ranging information.

In inner harbour of Incheon port, there are two lock gates (50KT, 10KT) which have two gates per lock gate in inner/outer sides except a gate in inner harbour side of 10KT. Due to the lack of the fore-mentioned gate, the use of 10KT lock gate is suspended in energy 3 years for regular maintenance. Now an additional gate is under construction in order to improve the efficiency of the 10KT lock gate. This paper will be aimed to evaluate the operational utilization levels of lock gates in present and future. The operational utilization levels of lock gates in 1998 are evaluated 0.2119 in 10KT lock gate, 0.2061 in 50KT lock gate which were considered the 46.5 closed days every 3 years for 10KT regular maintenance. The levels are estimated to 0.2246(10KT), 0.2539(50KT0 in 2006 and 0.2241(10KT), 0.2560(50KT) in 2011. The levels of 50KT lock gate in 2011 are evaluated to be more rapidly increased up to 24.5% from the levels in 1998.

Numerical simulations were done using depth integrated ADCIRC model in order to evaluate dynamic response on the inner Saemankeum reservoir due to flood flow and gate operation for the both situations of dike construction and inner development. According to 2-dimensional dynamic flood routing, temporal variation of hydrographs shows sensitive at upstream riverine region while it becomes stable from the center part of the reservoir due to sudden expansion of physical changes. Dynamic response of hydraulic changes such as water surface elevation and velocity on the inner region arises suddenly by gate operation and more rapidly after the inner development than dike construction. Temporal surface fluctuation arises during inflowging of outer sea water and propagates upstream up to 10km to 16km in accordance with inner development status.

The Gyeongbok Palace was completed during the reign of King Taejo and King Sejong in the early Joseon Dynasty. The most remarkable spacious feature of the palace is that it has an inner palace wall without an outer palace wall. The absence of the outer palace wall had its origin in the palace of the late Goryeo Dynasty which did not provide the outer palace wall. Gwanghwamoon was the main gate of the palace, and the office buildings of the Six Ministries were arranged on the right side in front of the main gate. A wide road called Six Ministries Avenue was made between the builidings. The avenue was completed during the reign of the third king of Joseon, Taejong, and it was assumed that this arrangement was influenced by the government office arrangements of Nanjing, the early capital city of the Ming Dynasty. Gwanghwamoon held national rituals as well as the civic and military state examinations nations in front of the gate. The avenue was decorated with flowers and silks when kings and the royal families, or Chinese envoys enter the gate, and the civilians watched the parade, Because there was no outer palace wall, all the events held at Gwanghwamoon and the Six Ministries Avenue ware opened to the public, it was the unique feature of Gyeongbok Palace that the palaces of Goryeo dynasty and China did not have.

Nagaya is one of the traditional Japanese housing types in which multiple houses are attached together. In Nagaya, walls are shared by several houses but entrances are privately owned by houses. Nagaya consists of many wooden houses for common people located in parallel with narrow alleys between them. Nagaya was one of the representative housing types in Japanese architectural history. This research is to study the background of the origination of Nagaya in Japan, the characteristics of space and land planning, the features and causes of the changes in the space and land planning. In this research, we observed and analyzed unit plans of a block of gate-type Nagayas in Hanan, Osaka. The results are as follows. First, as the inner alleys(Roji) are closed, the number of entrances to each housing lot decreased from two to one since one entrance that used to be open to inner alleys(Roji) are permanently closed. Second, walls between streets and housing lots which used to be one of the outstanding characteristics of gate-type Nagayas are disappearing. Third, as the bathrooms are added to houses, the front gardens are being degraded to empty spaces or sometimes totally removed. Fourth, the space in the first floor of houses become family spaces, and that in the second floor is divided into private rooms for individuals.
