Noryang Temporary Palace was a place where king Jeongjo (1752-1800) would have lunch after crossing the Temporary Palace River on his way to Hwaseong Temporary Palace to worship at Hyeonryungwon, the tomb of his father, Sadoseja. The government offices in charge of ship bridge construction 'Jugyosa' and 'Byeoljangso' were located in the Temporary Palace. The central buildings of the Haenggung Palace, which ranged up to Yongyangbongjeojeong, were arranged to observe both 'Jugyosa' and 'Byeoljangso' from the Temporary Palace by lifting the ground from Sammun Gate to Yongyangbongjeojeong. Yongyangbongjeojeong, the center of Noryang Temporary Palace, features the style of royal palace architecture and functions of housing architecture. The 'Jugyosa' and 'Byeoljangso' buildings had eight quarters. According to the records, in addition, 15 wood sheds, 5 rice hubs, 3 barns, 1 side gate quarter, 1 front gate, 70 separate sheds, 2 suragan temporary buildings, oesammun gate and hongsalmun gate were found. Such architectural layout is matched with the Temporary Palace Jugyohwaneodo Painting.

Place names are generally composed of first half and second half, whether the originality of those names comes from Korean or Chinese. The first half, modifying the second half, represents the naming flexibility of the name, while the second half of the name points out its directive object, which refers to a branch of the name. For example, 'Myeong' in 'Myeongryang' and 'No' in 'Noryang' represent their naming flexibility while 'Ryang', constituting the second half, points out the name's directive object. The purpose of this study was to investigate the etymology of place names, 'Myeongryang' and 'Noryang', by figuring out the meanings of those two elements. In order to search for the meaning of the second half, 'Ryang', other examples presented in the related literature have been examined. The finding indicated that 'Ryang' means 'dol', or 'do', which refers to 'moon(door)'. Furthermore, it is found out that the meaning of 'Ryang' has been transferred from 'dol' or 'do' to 'moon(door)', furthermore, to the straits. Upon looking into the origins of those names on the field, it is interpreted that 'Myeong Ryang' has been meant as a door in which huge and rough waves cry out, and 'No Ryang' has been meant as a door in which huge and rough waves rise up.

Temporal and spatial variations of surface water temperature in Jinju Bay for the period of 2010~2011 were studied using the data from temperature monitoring buoys deployed at 17 stations in the south coast of Korea. Water temperature shows the maximum late in January and the minimum early in August. Seasonal variation of water temperatures at the north part of the bay is smaller than the middle and the south. In summer, the lowest and the highest of maximum water temperature are distributed around Jijok Channel which is located at the south of the bay. The fluctuations of water temperatures at Noryang and Daebang Channel are smaller than others because of vertical mixing caused by passage of strong tidal currents. Wind and strong currents affect on the stratification of the surface water layer near Daebang Channel. High temperatures come in frequently around the north area when eastward constant flows appear at neap tide as blowing westerly in the springtime at Noryang Channel. Spectral analyses of temperature records show significant peaks at 7~20 day periods at Noryang Channel, 7~20 day and semidiurnal at the west coast of Changsun Island and Jijok Channel and 7~20 day and diurnal at the middle of the bay. Temperature fluctuation at Noryang Channel shows high coherence and has leading phase with those at other stations in the bay. However, the phase of temperature fluctuation at Noryang Channel falls behind that at Daebang Channel. Daebang Channel has an influence on the temperature fluctuation only at the west and middle part of the bay. Cross-correlation analyses for the temperature fluctuation show that Jinju Bay could be classified into six areas; Noryang Channel, the area of convergence and divergence at the north, Daebang Channel, the west coast of Changsun Island, the mixing area at the middle of the bay and the south inside of the bay, respectively.

In this study, a numerical particle tracking experiment was conducted to assess the distribution characteristics of freshwater exclusion resulting from the discharge of Gahwa Stream into Sacheon, Jinju, and Gangjin bays, located downstream of the Namgang Dam. The number of particles discharged into Noryang Channel, Daebang Channel, and Changseon Strait was compared by releasing 1000 particles through Gahwa Stream under three discharge conditions: no discharge, discharge during rainfall, and discharge during flood. Evidently, the percentage of particles in the Noryang Channel increased, whereas that in the Daebang Channel decreased as the discharge from the Gahwa Stream increased. Approximately 95% of the material located downstream of the Gahwa Stream generally escaped through the Daebang Channel. However, as the discharge from the Namgang Dam increased due to rainfall, the percentage of particles in the Noryang Channel increased, reaching 45.5% during floods.

At the center of the Noryang waterway, the Gwangyang bay area (including the Yeosu Strait) is located at the west, and the Jinju bay area (including Gangjin bay and Sacheon bay) is located at the east. Freshwater from several rivers is flowing into the study area. In particula,r the event of flood, great quantities freshwater flow from Seomjingang (Seomjin river) into the Gwangyang bay area and from Gahwacheon (discharge from Namgang Dam) into the Jinju bay. The Gwangyang and Jinju bay are connected to the Noryang waterway. In addition, freshwater from Seomjingang and Gahwacheon also affect through the Noryang waterway. In this study, we elucidated the characteristics of the tidal exchange rate and residence time for dry season and flood season on 50 frequency, considering freshwater from 51 rivers, including Seomjingang and Gahwacheon, using a particle tracking method. We conducted additional experiments to determine the effect of freshwater from Seomjingang and Gahwacheon during flooding. In both the dry season and flood season, the result showed that the particles released from the Gwangyang bay moved to the Jinju bay through the Noryang waterway. However, comparatively small amount of particles moved from the Jinju bay to the Gwangyang bay. Each experimental case, the sea exchange rate was 44.40~67.21% in the Gwangyang bay and 50.37~73.10% in the Jinju bay, and the average residence time was 7.07~15.36days in the Gwangyang bay and 6.45~12.75days in the Jinju bay. Consequently the sea exchange rate increased and the residence time decreased during flooding. A calculation of cross-section water flux over 30 days for 7 internal and 5 external areas, indicated that the main essential flow direction of the water flux was the river outflow water from Seomjingang flow through the Yeosu strait to the outer sea and from Gahwacheon flow through Sacheon bay, Jinju bay and the Daebang waterway to the outer sea.

The ECOM3D is used to study the circulation characteristics and density current from the Sumjin River runoff in the Kwangyang Estuarine System, South Sea, Korea. Annual mean value of $120m^3/s$ was imposed from the Sumjin River. The numerical model results in terms of tidal height, current and salinity field show satisfactory with skill scores over 90%. The current velocity showed the range of 1~2.5 m/s during flood and ebb phases. In particular, very strong flow occur in the narrow Channels of Noryang, Daebang and Changson exceeding over 2.0 m/s. The tidal residual currents in the various locations in the Kwangyang Estuary showed the range of 1~21 cm/s, The density-driven current through the Yeosu and Noryang Channels are about 12 cm/s and 4 cm/s, respectively. The current path through the Yeosu Channel is deflected toward west Bank. Based on budget analysis of the volume flux, the volume flux through the Yeosu Channel and the Noryang Channel were estimated to be 97.4 and $22.1m^3/s$ accounting for the 81.5% and 18.5% of total flux, respectively.

From November 1968 to March 1970, a series of drift bottle experiments were carried out in waters adjacent to and in Chinju Bay with the following results. Of the bottles released, $50\~69$ per cent were recovered. 1. The circulation of Chinju Bay is usually caused by the tidal current except during the winter season when the northwest monsoon prevails to cause a wind-drift current. 2. Sea water in the southern part of Chinju Bay flows northward at ebb tide. The ebb current east of the central submarine bank in Chinju Bay flows northeastward toward Samchonpo Channel through the eastern depression of the bank contributing to form a cyclonic eddy. The ebb current west of the bank, however, flows northward toward Noryang Channel through the western depression of the bank. 3. The ebb current nea. the southernmost part of Chinju Bay flows eastward toward Chijok Channel. 4. At flood tide, the main stream of the tidal current in Noryang Channel flows eastward. Turning smoothly to the right, the southern branch of the flood current flows southward through the depression and along the isobaths at the western margin of the central submarine bank, while the northern branch, turning to the left, flows into the Chin-gyo Bay of Hadong. 5. flood current in the eastern area of Kwang-yang Inlet runs northeastward toward Noryang Channel. A small eddy develops near Kwanumpo of Namhae Island. 6. The results suggest that such a drift bottle experiment can be recommended for the attestation of currents, although it is not suitable for a quantitative study of coastal currents.

A series of physical oceanographic investigations of the circulation in the Kwang Bay' were carried out seven times from May 1974 to May 1975 every other month. The average water transports through the southern entrance of the' Kwang Yang Bay were approximately $1,014{\times}I0^6m^3$/half-tide in ebb current and $278{\times}10^6m^3$$405.6{\times}I0^6m^34/half-tide in ebb current, and $282{\times}10^6m^3 $/half-tide in flood current, at the maximum current intensity. The water from Seomjin River flows into the bay at an annual average rate of $84{\times}I0^6m^3$/half-tide, the rate being fluctuated from month to month from $6.0\times}10^6m^3 $to $11. 5{\times}I0^6m^3 $per half-tide.

This study examined the characteristics of eggs obtained from layer chickens reared with feed that included Tenebrio molitor larvae, which were in turn bred using feed that included dried food waste powder. The eggs showed a tendency to be slightly thinner in the treated groups, but the Haugh unit indicating freshness was higher in the treated groups than the control group, and the 5% larval-treated group showed the highest value. The color of the yolk tended toward higher redness, lower brightness, and lower yellowness in the 5%-treated group, which also showed similar crude fat and protein values to the control group; the 10%- and 15% larval-treated groups had lower crude fat and protein values, although the carbohydrate content was higher. Structural amino acids in the treated groups showed a higher ratio of non-essential amino acids to essential amino acids than the control. The polyphenol content, which is an index of antioxidants, was highest in the 5%-treated group, and it is thought that this may affect the storage and antioxidant properties of the eggs. Thus, when employed with a feed source to maintain high protein and high fat, T. molitor larvae may cause critical changes in the nutrient content of eggs and improve their freshness.
