군산 3.5 만세운동은 전북지역 최초의 독립 만세운동으로써 다른 지역 만세운동을 촉발시키는 계기가 되었다. 당시 미국남장로회는 군산, 전주, 익산에 기독교 학교를 세웠는데 이들 지역의 만세운동에는 이 학교의 학생들이 그 중심에 있었다. 그 대표적인 사례가 군산영명학 교이다. 이 학교는 전킨 선교사가 설립하여 앞선 신학문과 기독교 정신을 가르쳤고, 3.5 만세운동 당시 교장이었던 인돈 선교사는 미국으 로 건너가 한국의 독립만세운동의 정당성을 적극적으로 알렸으며, 영명학교 졸업생이자 교사인 박영세는 3.5 만세운동을 주도했다. 이들 은 학생들에게 나라 사랑과 비폭력평화의 기독교 정신을 가르쳤고, 학생들은 3.5 만세운동에서 배움을 실천으로 옮겼다. 3.5 만세운동과 그 정신은 그 후 군산지역의 자발적인 만세운동으로 계속 이어졌다.

황해 군산분지 지역의 지구조를 해석하기 위하여 2006년 획득한 선상 자력 자료와 Scripps 해양연구소에서 제공하는 고도계위성중력 자료를 이용하였다. 중력자료에 대해 파워스펙트럼 분석과 심도역산이 수행되었고, 자력자료 분석을 위해 분석신호기법과 가중력변환 및 이에 대한 역산을 수행하였다. 중자력 자료 분석 결과 남 중소분지 중심부로 갈수록 기반암 심도가 증가하는 양상이 나타나며, 기반암의 심도는 깊은 곳에서 6-8km, 낮은 곳에서 약 2km로 해석되었다. 또한 남중소분지 중심부이서 기반암 심도와는 달리 중력이상과 자력이상이 높지 나타나는 것은 주변 기반암보다 밀도가 높은 화성암의 관입에 의한 효과로 해석되며, 이는 동일지역에서 수행된 정밀 탄성파 해석 결과와 잘 부합하고 있다.

1997년 11월부터 1998년 6월까지 총 4회에 걸쳐 군산인근 해역을 대상으로 Vibrio 속의 분포와 특성을 조사하였고, 분리동정된 Vibrio 속 3종(V. anguillarum, V. vulnificus, V, metschnikovii)을 대상으로 해수에서 수온 변화에 따른 생존을 관찰하였다. 조사 기간 중 총 해양 종속영양 세균의 분포는 평판도말법으로는 1.2±0.6×103~2.0±1.5×104

대산공단과 군산공단의 대기오염에 의한 삼림피해현상을 연구하기 위하여 조사구를 각각 5개, 3개씩 설치하였다(1개 조사구 당 면적 500m2). 대산공단 삼림의 교목층 아교목층의 우점종은 소나무와 곰솔이었고 관목층에서는 진달래와 참나무류가 우점종이었다. 종다양도는 0.4859~0.9202 이었으며, 조사구간의 차이가 심하게 나타났다. 토양 pH는 4.67~5.12로 약산성이었다. 대산공단지역에서는 아직 대기오염에 의한 삼림의 피해가 심각하지 않은 것으로 나타났다. 군산공단삼림의 교목층 및 아교목층의 우점종은 곰솔과 소나무이었다. 종다양도는 0.8115~l.0983이었고 오염원과 가까운 조사구가 가장 낮게 나타났다. 토양 pH는 4.32~4.76으로 강산성이었다. 군산공단의 오염원 인근삼림은 울산공단과 유사한 피해양상으로 심각한 피해를 받고 있었다.

The tidal current observation was carried out to investigate the characteristics of the circulation and diffusion in the vicinity of Kunsan harbor on March 1415, April 1∼2, and 13∼14, 1988. By harmonic analysis, the semidiurnal tidal current of more the amplitude of vibration was prevailed and its rotary direction was anti-clockwise in this harbor. Apparently constant current which is generated by out flow of Geum river was found to flow from Kunsan inner harbor to Janghang with the speed of about 30㎝/sec. It can be easily considered that deposition of much sand and mud which come from Geum river in Kunsan inner harbor and erosion in Janghang harbor will be occurred respectively. Autocorrelation and diffusion coefficient of each components was calculated to study the some characteristics of diffusion. Correlogram of the east-west component current was regular and nearly the same period as semidiurnal current. But it appeared irregular and considerably small value in the north-south component correlogram. Diffusion coefficient was 4 order in X-axis and 2∼3 order in Y axis in each study station.

This study was conducted to evaluate water quality in coastal sea of Kunsan using multivariate analysis. The analysis data in Coastal Sea of Kunsan use of surveyed data by the NFRDI from April 2000 to November 2002. Twelve water quality parameter were determined on each sample. The results was summarized as follow ; Water quality in coastal sea of Kunsan could be explained up to 62.782% by four factors which were included in loading of nitrogen-nutrients by Keum river(24.688%), suspended solids variation (12.180%), seasonal climate variation (18.367%) and variation of DIP (10.546%). To analyze spatially and monthly variation by factor score, it was divided by inner area and outer area spatially, and spring and summer monthly. The result of time series analysis by factor score, inner area of Kunsan coastal sea(St.1 and St. 2) was the most affected by nitrogen-nutrient and suspended solids due to runoff by Keum river. It could be suggested from these results that it is important to reduce the pollution loads from Kuem river for the control of the water quality in coastal sea of Kunsan.

Recently, eutrophication or lake and reservoir has become serious problem to man who want use that water for several purpose. In order to solve the eutrophication problem, the trophic state of that eutrophic lake and reservoir should be measured properly. For the purpose of this, various method to indicate the trophic state of lake and reservoir was developed by many researchers. This research was conducted to evaluate characteristics and eutrophication of water qualitymfor small scale reservoir in Kunsan. On-site investigation to 5 reservoirs and laboratory experiment were carried out during four seasons from November, 2003 to July, 2004. Twelve items measured field ana a laboratory. Measured data was analyzed to quantitative method by multivariate approach and eutrophication index. The result is summarized as following. 1) Showing the characteristics of water quality for reservoir in Kunsan, Okgu reservoir and Oknua reservoir was exceeded 4 grades of agricultural water standard in TP, TN and COD. This means that eutrophication was gone much, therefore, water-purity control of reservoir need. While, Mije reservoir that is used to Kunsan citizens' recreation was good in water quality. But, water quality exceeded 4 grades of agricultural Dater standard sometimes. 2) As a results of correlation analysis between variables of water qualify, Interrelation between variables which is connected with eutrophication was expressed good relationship as above 6.000 in correlation coefficients. The correlation coefficient(r) between COD and chlorophyll-a, total phosphorus and chlorophyll-a, total nitrogen and chlorophyll-a were 0.750, 0.720 and 0.600 respectively. Therefore, Change of water quality can grasp according to eutrophication progress degree. 3) If do evaluate to eutrophication by quantitative method which is proposed by OECD, US-EPA and Forsberg & Ryding, in the case of chlorophyll a, Okgu, Oknua and Daewi reservoir was eutrophic state and Mije and Geumgul reservoir was mesotrophic state. But, estimation by TN and TP showed highly eutrophic state (hypereutrophic) in all reservoirs. 4) If do evaluate by eutrophication index which is Carlson's TSI, revised carlson TSI and Walker's index, in the case of chlorophyll a, TSI values of Okgu, Oknua and Daewi reservoir is eutrophic state more than 50 and Mije and Geumgul reservoir was mesotrophic state as range of 40∼50 in TSI value. But, in the case of TP as nutrients, all reservoirs showed highly eutrophic state which was exceed to 70 in TSI value. According to above results, the water quality for small scale reservoirs in Kunsan is progressing by trophic state. therefore, for continuous use as agriculture water, we had better do establishment of management plan about water quality.

Diurnal variations of air quality due to the characteristic features of local weather phenomena over Kunsan, Taegu, and Pohang are analyzed using various synoptic wind fields and the characteristics of local weather during the period of 1990 to 1992. The air pollutants analyzed are sulfur dioxide(SO_2), nitrogen dioxide(NO_2), and oxidants (O_3). The synoptic wind fields estimated at over the 850 hPa geopotential height are divided in terms of four wind directions and two wind speed categories for each season. The synoptic weather conditions are also classified into two categories depending on the total cloud amounts. The present study shows that the SO_2 concentration over Kunsan, and Taegu was maximum at the two or three hours after sunrise and second primary was three or four hours after sunset. On the other hand, its concentration over Kunsan was maximum at 1900 LST or 2000 LST. The O_3 concentration over the three cities shows its maximum in the afternoon when the solar radiation is strong. The NO_2 concentration over Kunsan shows in reverse proportion to the 0_3 concentration over the Kunsan.
