Jeonbug area is an ideal place for produciug Korean handmade paper, and has a long history of it, There used to be more than 70 plansts, but only 45 of them are at present being operated. Plants operated on a small scale produce paper as a subsidiary work of farm families during the season free. Recently the export of Hwaseunji(Korean handmade artistic paper) and the increase of the demand of the paper in the country have revitalized. The results of the investigation of their location, the continuity of their preperaion, their facilities and the like are as follows 1) Of 74 plants, 20% are located in Jeonju city, and 32% in Wanju district. 2) The plants in Jeonju city and Wanju district produce Hwaseunji, whereas those in the other districts produce sliding screen paper, poor quality paper made of mulberry bark, and Hwasenuji. 3) The bark of the paper mulberry as raw material is to be cooked for 2-3 hours with 10-13% of NaOH or Na₂CO₃etc 4) As the utilization of waste vellum paper rapidly increase in quantity, its amount comes to 50% of materials. As a result it has now become main material. 5) The production amont of paper mulberry was 617_M/T in 1976, and its consumption amount was some 407_M/T. 6) It is advisable to leave alone the cooked bark of mulberry for 5-12 hours. 7) It is advisable to treat waste vellum paper with 15-20% Na₂CO₃. 8) The storage liquid of Abelmoschus manihot medic root is used with the mixture of 2% formaline or 1.5% formaline and 1% CuSO₄·5H₂O. 9) It would be better to see a mixture of 0.02% HgCl₂, 0.1% formaline and PAM for the prevention of decreasing viscosity. 10) In manufacturing sliding screen paper, it is advisable to increase the proportion of the bark of paper mulberry and to revive its originl quality of Korean handmade paper. 11) The output of korean handmade paper in Jeonbug area amounts to Won 53,100,000 in the former half of the year 1977(January-June). 12) Plants operated on a larger scale must be encouraged to be equipped with hollander beater and produce Hwasenuji.

Phlogiston 이론과 그 비판

任齊彬 全北大學校 1972 論文集 Vol.14 No.-

중세까지 Aristoteles의 자연과학의 사상과 그의 4원소설에 기초를 둔 연금술사상 때문에 물리학이나 천문학 분야에서는 이미 고대와 중세의 학문적 성격을 벗어나 근대적인 학문으로 그 모습을 나타냈는데 화학만은 현자의 석(Philosopher’s Stone)을 얻기에 장구한 세월을 보냈던 고로 화학은 발전이 뒤늦었다. 그러나 화학분야에서도 점차로 합리적 화학의 방향을 모색하게 되었다. Paracelsus(1493-1541)는 연금술의 추구에서 탈피하여 화학은 의학의 효력을 연구하고 새로운 의약을 만드는 것이 유일한 목적이라고 주장하여 소위 의화학시대의 문을 열었고, 또 van Helmont(1577-1644)는 최초로 공기와 다른 기체를 구분하고 계량적 방법을 화학에 도입할 것을 역설하였다. 그리고 Robert Boyle(1627~1691)은 연금술과 의화학에서 그들의 전통적인 원소관의 모순을 지적, 학학을 연금술과 의화학에서 해방시켜 합리적 화학으로 그 방향을 전환시키려고 했다. 그러나 고대 4원소설의 결정적인 부정실험이 없었고 아직 공기를 원소로 믿고 있었던 고로 화학변화중 연소의 본질을 설명할 수 없어 화학발전에 많은 지장을 초래하고 있었다. 이러한 처지에서 화학변화 특히 연소현상을 통일적으로 설명하려고 노력한 학파가 나타났다. Becher와 Stahl은 물질적 변화 특히 연소현상에서 오는 물질의 변화를 단 하나의 원리로 설명하려는 생각이 들어서 연소물질에 하나의 입자적 가상물질인 Phlogiston을 생각함으로써 Phlogiston시대의 막이 올랐다.

The effective methods of phosphorus removal in the small scale or large scale of sewage disposal plant were: 1) biological method [anaerobic oxic system, activated sludge (removla rate, 20-30%)] 2) flocculation by coagulants [FeSO_4, Al_2(SO_4)_3, poly aluminium chloride] 3) recrystallization by hydroxy apatite 4) Ca(OH)_2. But the ability of phosphorous removal was certified in mineral pyrite, which is a new method. And the ability was compared with other removal methods. In the 0.002% of Na_3PO_4 solution, contacting with mineral pyrite for 20 minutes, the removal rate became 90%. Mineral pyrite reacts neither strong acids nor NaOH alkali solution, but adsorbed Na_3PO_4 is easily solubed to acid, 2% H_2SO_4. When mineral pyrite became a critical point by adsorbed phosphorous, if the adsorbed phosphorus was washed out, and was treated with saturated Ca(OH)_2 solution, the ability of phosphorous removal is regenerated. It is useful and effective to remove 90% phosphorus of 0.002% Na_3PO_4 solution in 2m height of pyrite column, at 100ml/minute flow rate. Phosphrous concentration of Kumkang is low at the upper stream and high at the down stream. COD, SS and phosphorous concentration of the tributary rivers are very high, especially, the plentiful algae and foul smelling were easily certified at Kap-Chon and caused the eutrophication of main river. Therefore, the pollutants must be completely removed at the sewage disposal plants near cities.

In our country, the Ministry of Health and Social Affairs adopted the WHO standard from December 1993. However, the standards have not been monitored carefully throughout the province and there is little research on the effects of aluminum on people's health and management of cleaning bed. In this research, we measured Al in raw and treated water of major cleaning beds of chonbuk province and got the situation of contamination. The results are summarized as follows; 1. The range of the aluminum concentration in row water is from ND(non-detected) to 0.08㎎/ℓ, to average is 0.03㎎/ℓ, and it is the highest figure at 0.08㎎/ℓ in Wal-Iock bed of Nam-Won district. 2. The major concentration extent from ND to 0.009㎎/ℓ, ranks 35% and its average is 0.07㎎/ℓ. 3. When we analyzed the aluminum concentration over the passage of time, we found a lot of A1 in samples that were taken from P.M 10 to A.M.I. 4. There are no samples exceed 0.2㎎/ℓ which is the drinking water standard of WHO. 5. It is revealed that the average concentration is 0.15㎎/ℓ in big cities whose population supplied water is more than 500,000. 6. Investigating the effect on the coagulant, we knew the factors that the residual Al concentration. In the place where no coagulant was used Al concentration is 0.04㎎/ℓ on the average. The ones using the aluminum sulfate and activated carbon is 0.09㎎/ℓ on average. So the one using Al_2(SO_4)_3 is 0.11㎎/ℓ on average. 7. The concentration fluctuate with the seasons : Jenuary is 4 times as much as July. 8. It is also connected with the other water pollution the consumption of KmnO_4, NO_3-N, SO_4^2- ect.

Chongeub Chon (drainage area : 50.1㎢, length : 23.5㎢ is one of the severely polluted streams among the branches of Tongjin river by industrial wastewater and domestic sewage. In order to investigate the pollution source and its influence at Chongeub Chon in Chonbuk, water quality analysis were undertaken at 7 stations from January to November in 1988. The following conclusions were obtained as a result of this investigation. 1. The pollutions of Chongeub Chon in winter and autumn is more serious than in summer because a little quantity of rainfall. 2. Because domestic sewage inleted the downstream at Site 3. from pollutants concentration at the downstream of that point was increased. 3. the portions of Chongju sewage and industrial complex westewater in Chongeub Chon are 68% and 32% as BOD basis, respectively. 4. In oredr to purify the stream, it was necessary to the intercepted domestic sewage and the constructed rubber dam for flux control. 5. It is necessary to construct the weatewater treatment plant oxidation pond(ditch) is economically proper to the process of that plant. 6. A pollution level of Chongeub Chon is more seriously than the Han river and Mangyoung river, lower than Auyang Chon, Kwangju Chon and Wonju Chon.
