  • 우리나라 수출입화물의 주요 관문이었던 마산항이 최근 들어 침체와 위기를 벗어나지 못하고 있다. 즉, 인접 대형항만(신항)의 건설에 따른 물동량의 감소, 항만시설의 노후화, 친수 공간의 부재 등 항만발전에 따른 여러 가지 문제점이 제기되고 있다. 따라서 마산항의 지속적 발전을 위해서는 항만시설의 현대화, 구항의 재개발과 친수공간의 확충, 그린포트의 구축과 관광항만의 개발을 조속히 추진하는 한편, 새로운 고부가가치 항만으로 발전되어야 할 것이다. 향후 마산항의 활성화를 위해서는 중량화물 및 대형화물의 물류전문항으로 특화하는 차별화 전략을 적극 추진하여야 할 것이다.

  • In order to understand the tide and current around the sea route of Jinhae and Masan passages, tide measurement and 2D numerical model experiments of tidal current and residual flow were carried out. Tide is composed of 84% of semi-diurnal tide, 11% of diurnal tide and 4% of shallow water tide, respectively. Phase lags of the major components for the tide around the study area have little differences. The flows are reversing on the whole, but have rotational form around Jamdo Island, south of Masan passage in spring tide and Ungdo Island, north of Masan passage in middle and neap tide. Current flows the speed of 50 cm/s in the sea areas near small islands, 5 cm/s in Jinhae harbor, Hangam bay and near Jinhae industrial complex and 20-30 cm/s in Jinhae passage, Budo channel and Masan passage. Tide-induced topographical eddies are formed near small islands, but few eddies exist and the flow rate of less than 5 cm/s tidal residual current formed in Jinhae and Masan passages. The flows in Jinhae and Masan passage give a good condition for a passage into Jinhae and Masan harbor.

  • We measured the concentrations of organic matter and metallic elements (Al, Fe, Cr, Mn, Ni, Cu, Zn, As, Cd, Pb and Hg) in the surface sediments of Masan Harbor (in the southern sea, Korea) to evaluate the geochemical characters of sediment and the pollutions by organic matter and metallic elements. The mean grain size of the surface sediments in the study area ranged from $5.6{\phi}$ to $7.8{\phi}$, indicating silt sediment. The water content of the surface sediments exceeded 60% except at some stations. The contents of ignition loss (IL), total organic carbon (TOC) and total nitrogen (TN) ranged from 7.2-14.3%, 1.2-3.2%, and 0.10-0.28%, respectively. Based on the C/N ratios, the organic matter in the surface sediments of Masan Harbor may originate from terrigenous sources including fluvial inputs (mainly sewage in urban areas). The chemical oxygen demand (COD) and acid volatile sulfide (AVS) ranged from $11.3-29.9\;mgO_2/g\;dry$ and 0.20-4.47 mgS/g dry, respectively, and low concentrations were observed near a shipping route. In addition, the concentrations of metallic elements showed large spatial variations in Masan Harbor and the distributions of metallic elements were also comparable to those of organic matter. This implies that the distributions of organic matter and metallic elements in the surface sediments of Masan Harbor are mainly controlled by biogenic matter and artificial action (mainly dredging). In addition, we calculated the enrichment facto. (EF) and geoaccumulation index (Igeo) in order to evaluate pollution by metallic elements. The enrichment of metallic elements relative to Al was three to eighteen times higher at the study sites, compared to levels in the Earth's crust except for Fe, Ni and Mn. In addition, the Igeo class indicated that the surface sediments in the study area were moderately to strongly polluted in terms of metallic elements.

  • A 3-D particle tracking model with normalized characteristic equations has been developed to predict the variation of near-field mixing characteristics and the far-field transport of the effluent plumes discharged from sea outfalls. The model was applied to the case study on the Masan sea outfall plumes discharged through a submerged multiport-diffuser. Numerical simulations of the effluent transport for 15 days which cover neap and spring tidal cycles in Masan Bay were conducted using fall velocities of the solid wastes and the initial plume characteristics obtained from normalized near-field characteristic equations. The results showed that time variations in near-field minimum dilutions with tidal ambient flow conditions are about $45{\sim}49$. Most of the heavy particles in the effluent plumes were settled and deposited in the vicinity of the outfalls immediately, and the finer particles were transported eastwards 3 km away from the outfalls for 15 days. A similar depositional trend of contaminated sediment was also found during a recent field survey.

  • Masan barber was situated in S.Korean southern central coast. And it is contributing greatly in S.korea's economy development to international trading port of Heaven's blessing that possess natural, geographical situation. Also, because there are Masan free tax area and chanwon heavy industrial complex, sachon air industrial complex etc. on back, it is important permanency in our country. Specially, because inland transport routes such as southern highway, Guma highway and national road system are developed well, the importance is very high. Masan harbor 1899.05.01 be that opened, the 1st and 2nd (central pier) was build 1938∼1944 year, and the 3rd pier was 1973∼1978 year. the 4th pier was 1974∼1983 year, 5th pier was 1984∼1988, 6th pier (west pier) was 1985∼1992 year. it was developed over 100 years. But, it did great many harbor and bay development of last 100 yens but research about coastline change and seashore reclamation is insufficient. Therefore, this research executed research about coastline change of Masan bay of last 100 years, In this study, we analyzed aerial photographs and tide data for the past 100 years using digital aerial photo analysis and GIS techniques for each 3-year interval. We abstracted beach DEM (digital elevation model) and ortho aerial photographs, and conducted a space analysis. As a result, we were able to identify changes in the area As a result, we drew 10 years cycle coastline change of Masan bay. and we can detect bay coastal line change and calculate refill rate.

  • 1999년 8월, 마산만의 용존산소는 표층으로부터 저층으로 가면서 급격히 감소하는 수직분포를 보였다. 모든 정점에서 저층수중 빈산소현상이 나타났으며 무산소 상태인 정점도 있었다. 마산수로에서 표층수의 용존성 Cd, Zn은 마산만 안쪽에서 바깥쪽으로 가며 점차 감소하였고 Pb의 경우 안쪽에서부터 바깥쪽으로 가며 증가하는 경향을 보였다. 저층수중 Cd, Cu Pb, Zn의 용존성 미량금속농도는 표층수보다 대체로 낮은 농도를 보였으나 Co는 빈산소 상태이거나 혐기성 환경인 저층수와 퇴적물로부터 용출되었기 때문에 저층수에서 높은 값을 보였다. 입자성(acid-teachable fraction) Cd, Cu, Pb 그리고 Zn은 표층보다 저층에서 대체로 높은 함량을 나타냈다. 본 조사에서는 저층수의 용존산소의 포화율이 낮을수록 Cd, Cu, Pb 그리고 Zn의 K/sub d/ 값이 증가하는 경향을 보였다. 표층퇴적물에서 Cd, Cu 그리고 Zn 등 원소들은 내만 육수유입원으로부터 멀어질수록 농도가 감소하는 경향을 보였다.

  • Hydrodynamic mixing characteristics of submerged effluent discharges into Masan Bay were investigated by both field observations and numerical model simulations. CORMIX model, a length-scale mixing model, was adopted to obtain the near-field dilution and wastefield characteristics of the effluent discharges into Masan Bay. Model predictions of the near-field dilution rates were in a good agreement with field observations in summer and winter seasons. Seasonal variations in the dilution rates showed that the highest dilution rate was obtained in winter while the lowest dilution rate was in summer. As the effluent discharges are increased with the treatment capacity expansion to be completed by 2011, the dilution rates are expected to be much reduced and the near-field stability of the wastefields will become unstable due to the increased effluent discharges.

  • Objectives: Outdoor workers are exposed to thermally stressful work environments. In this study, heat stress indices for harbor workers in summer were calculated to evaluate thermal comfort based on a human heat balance model. These indices are Physiological Subjective Temperature (PST), Dehydration Risk (DhR), and Overheating Risk (OhR) according to respective stage of cargo work in a harbor. In addition, we constructed a forecast system to provide heat stress information. Methods: Thermophysiological indices in this study were calculated using the MENEX model (i.e. the human heat balance model), which used as inputs the meteorological parameters, clothing insulation, and metabolic rate for each stage of cargo work in the harbor of Masan over the course of seven days, including a four-day heat wave. The forecast heat stress information constructed for Masan harbor was based on meteorological data supported by the Dong-Nae Forecast from the KMA (Korea Metrological Administration) and other input parameters. Results: According to higher metabolic rate, thermophysiological indices showed a critical level. In particular, PST was evaluated as reaching the 'Very hot' or 'Hot' level during all seven days, despite the heat occurring over only four. It is important in a regard to consider the work environment conditions (i.e. labor intensity and clothing in harbor). On a webpage, the forecast thermophysiological indices show as infographics to be easily understand. This webpage is comprised of indices for both current conditions and the forecast, with brief guidance. Conclusion: Thermophysiological indices show the risk level to health during a heat wave period. Heat stress information could help to protect the health of harbor workers. Further, this study could extend the applicability of these indices to a variety of outdoor workers in consideration of work environments.

  • This study aims at examining the change of the urban space of the original Masan Area during the Japanese-forced colonial era of Korea(1910-1945) after circa 1912. That year is very important because the modern map of land was introduced. The land area of the original Masan was about $17,000m^2$ composed of small houses and shops. Colonial era could be divided into 3 periods according to the change of colonial policies. And the change of the urban space is examined according to these 3 periods. During the 1st period(1911-1920) the following 3 development occurred. 1. Land was reclaimed along the coast line by a Japanese civilian named 'Bakgan'. And his ownership of land continued until 1945. 2. A government ware house(Cho-Chang), which was the symbol of Masan harbor, was demolished and the land was divided into small lots. 3. Main artery and trunk roads(14-15m wide) were built replacing 2-3m wide narrow roads and connected to the reclamation land. During the 2nd period(1921-1930), also land reclamation and road making was more frequently carried out. And the infrastructure of the city was developed gradually. Also public buildings began to be built. Modern roads were constructed city-wide not only in the center of the city. In the 3rd period reclamation was at its peak. Especially Sinpo-Dong area located at the middle of New and original parts of Masan was reclaimed connecting 2 parts and making of a central Masan. During that time original Masan was enlarged because of reclamation. The coast line of Masan became straight from e original organic shape. Roads were constructed in the outskirts also. The size of land lots were more or less the same during the colonial era. But gradually lots were divided into smaller lots. Japanese entrepreneurs gradually occupied the central area of the original Masan until the liberation day. But Chinese ownership of land gradually diminished.
