There are two main problems in formulating population policies. First, is it reasonable to formulate population policy in isolation from other social and economic policies? It is the personal belief of Mr. S. Park that a population policy should be regarded as a part of other social and economic policies. Second, there appears to be no clearly formulated long range objectives in conducting the current population redistribution policy; 1) Community development program should be based on the recognition of the special characteristics of the area. And the re-location program for industries should be strongly supported with special tax and loan consideration. 2) The policy aimed at the dispersion of population should be conducted with the program of providing an equal educational opportunity regardless of geographical location, and family planning. Discussants: Koh, Kap Suk and Chang, Man-Ki. 1. Urbanization may be considered as an inevitable result of industrialization. In order to regulate effectively the population movements into urban centers, there should be a clearly formulated population policy in co-ordination with other social and economic policies. 2. Let us assume that Korea will achieve the zero population growth rate by the year 2,000. The fact that currently there are no long range "visional" proposals to deal with the population composition and distributional problems indicates that there has been no comprehensive research about population planning. 3. The optimal population size for Korea should not be thought of in terms of a static concept but a dynamic concept which is related to manpower supply and housing problems. 4. The problem of aging should not be looked at solely as an economic issue. Instead, it should be examined from a humanistic point of view where high priority is placed on restoring human dignity for the older citizens. Response of Mr. Park: 1. There is a tendency to over-emphasize the economic side of population issues. It should be pointed out that a man not only provides labor which is an input for the production of economic goods, but also he is a consumer for whose welfare economic goods are produced in the first place. It should be remembered that economic growth has beneficial impacts on the population but it also has harmful effects. 2. In order to make the government officials aware of population issues, it has been proposed to the Population Policy Evaluation Committee that the courses in population studies be included in the study program for the re-education of government employees. 3. Issues involved in population dispersion: Urbanization is an inevitable process of economic development. Problems arising from urbanization should be solved not by forcefully preventing the migration of population from rural areas to urban centers but by reducing the rural-urban gap in the living conditions. This policy has already been implemented to some extent as indicated by the government's policy of decentralization of industries and Saemaul Movement. In summary, the basic policy of government is to slow down the rural-urban migration by providing incentives to stay in farms in the rural area rather than by the strong-handed method of preventing the internal migration.

백일해 백신이 Streptozotocin 유발성 당뇨백서의 당대사에 미치는 영향

박상기,문경래,박춘호,김갑승,박영봉,이병래,양남웅 朝鮮大學校 附設 醫學硏究所 1991 The Medical Journal of Chosun University Vol.16 No.1

Streptozotocin(STZ) may produce a permanent form of insulin-dependent diabetes (IDD) in experimental animals. This STZ-induced diabetes has become an useful model to study the pathogenesis of IDD in man primarily because it approximate clinical findings and also because it lends itself easily to controlled manipulation. The diabetogenic activity of STZ, however, is known to be modified by several agents such as nicotinamide, diazoxide, adrenergic blockers and pertussis vaccine (PV). The present study was undertaken to observe the protective effect of PV or boiled pertussis vaccine(bPV; incubating the PV at 80℃ for 30 minutes) against the development of IDD induced by STZ in young rats, and also the effect of PV on the activities of glycolytic & gluconeogeneic enzymes in both liver and muscle of rat. PV at a dose of 1.2×10^(10) microorganism was administrated intrapntoneally on 3days before & 7days after a single injection of STZ (GO㎎/㎏ body wt). The blood glucose and insulin levels were measured at 1st wk, 2nd wk, 4th wk, 6th wk and 8th wk after STZ injection, and the enzyme activities were exemined at 8th wk. The following results were obtained. 1. No significant difference was noted in blood glucose levels between STZ group and STZ+PV or STZ+bPV groups (P>0.05). 2. Blood insulin levels in STZ group decreased significantly from 2nd wk(P<0.05). Compared with STZ group, blood insulin levels in STZ+PV & STZ+bPV groups were higher, but not a significant value except at 2nd wk in STZ+PV grouP (P<0.05). 3. Compared with STZ group, hepatic glycolytic enzyme activities were significantly increased in STZ+PV or STZ+bPV groups, and muscular glycolytic enzyme activities were significantly increased in STZ+PV or STZ+bPV groups. 4. Compared with STZ group, hepatic gluconeogeneic enzyme activities were significantly increased in STZ+PV or STZ+bPV groups. These results suggest that the PV has somewhat protective effects on blood insulin levels and tissue glycolytic enzyme activities in rats, but it could not reduced blood glucose levels significantly, probably because of excessive increase of hepatic gluconeogeneic enzymes.

This study was conducted to find a correlation between blood COHb and calculated COHb with expiratory air and related variables such as occupational and smoking factors. Author selected 69 healthy workers in 8 workplaces suspected CO exposure. Basic informations were collected by self-reported questionnaire and medical history taking. Author measured Indirect COHb concentration with expiratory air using Micro II-Smokerlyzer and blood COHb concentration using Oxymeter. The results of the study were summarized as follows : 1. In the smoker, mean blood COHb and calculated COHb with expiratory air were 2.21±0.98% and 2.27±0.97 %, and there was not a statistically significant difference. In the non-smoker, mean blood COHb and calculated COHb with expiratory air were 0.42±0.43 % and 0,65±0.30 %, and there was also not a statistically significant difference. 2. There were positive correlations between blood COHb and calculated COHb with expiratory air in both the smoker (r=0.91, p=0.0001) and non-smoker (r=0.73, p=0.0001). 3. In the smoker, the factors affected COHb were total smoking index (Pack × years) and passed time after the last smoking. 4. In the nonsmoker, the parking and driving groups had higher COHb concentration than others (p<0.05). In conclusion, there was no significant difference between indirect COHb concentration with expiratory air using Smokerlyzer and blood COHb concentration and there was a highly significant correlation between indirect and blood COHb concentrations. Therefore indirect COHb concentration with expiratory air is a useful screening method for CO exposure. Author suggest the resection of smoking during at least 90 minutes before measuring COHb concentration in order to exclude smoking effects.

흡착에 의한 식염폐수의 처리

박영태,도갑수 慶北工業專門大學 1980 論文集 Vol.18 No.-

식품공장에서 배출되는식염폐수는 주로 채소를 소금물에 절이는 과정에서 생겨나며, 이 폐수는 생물학적으로 분해 불가능한 염과 유기고체의 혼합물로 되어 있으므로 응접 및 생물학적 처리만으로는 좋은 결과를 얻을 수 없다. 또한 소금의 농도가 10% 이상을 유지하므로 이 소금을 재생시키는 것이 바람직하다. 본 연구는 식염폐수를 공장에서 직접 채취하여 모래 층에서 여과한후 흡착질용액으로 하고 흡착제로 zeolite와 입상활성탄을 사용하여 회분흡착실험을 통하여 흡착평형과 흡착능 및 식염폐수의 재상용 능성을 조사하였다. 평형에서의 흡착량은 입상활성탄이 6.1㎎/g adsorbent, zeolite가 5.5㎎/g adsorbent가 되었다. 실제 공장에서 쓰여질 흡착탑의 설계를 위하여 fixed bed에서 연속실험을 했으며 유량과 폐수의 초기농도 및 흡착제 종류에 따른 break through curve 를 얻어 설계를 위한 제반인자를 설정하고 흡착 process를 제안하였다. 제안한 process의 고정투자비를 각 흡착제별로 계산하고 경제적인 타당성을 고찰한 결과 폐수의 량을 20㎥/day로 가정했을때 고정투자비 기준으로 약 0.12원/liter SPB 이 되어서 경제성이 있음을 알았다. A continuous process ofr recovery of spent pickle brine(SPB) by preliminary filteration on a sand bed to remove suspended solids, followed by adsorption treatment in an granular activated carbon and zeolite-sand micture column to remove colour and odor causing organic compounds is investigate. Batch isotherm adsorption experiments revealed that the adsorption capacity of the SPV-adsorbent system is respectively 6.1㎎ total organic carbon per gram granular activated carbon and 5.5㎎ total organic carbon per gram zeolite a t25℃. It is estimated that a low capital investment of 0.12 won per liter of recycled treated SPB is required for a 20㎥/day capacity. This cost is much lower than that of fresh salt, and thus will be defrayed by savings on recycled salt.

This study conducted a survey on 401 soccer club members for lifetime sports of Seoul and Gyeonggi district in 2004, as part of the attempt to inquire injury types and precautions between them and to offer basic data for their injury prevention and treatment. The results are as following. First, for injury season it showed that this is happening with th highest level do injury at the winter season, compared with order season. Second. for injury cause, it showed that this is happening with the highest level of injury by the foul play and severe body battle with counterparts. Third, for injury frequency, it showed that this is happening with very low level, if it takes a long time in warming up before the game. Fourth, for injury part by position, it showed that GK players are largely wounded at the shoulder. FW and DF players at the waist, elbow joint, pelvis, hand and wrist, and MF and FW players at the leg, Lastly, for injury type, it showed that DF and FW players largely undergo distortion. MF, FW, DF and GK players in the listed order at the muscle pain and MF and DF players leg pain, compared with other position. The results demonstrates that it is imperative to wear protective devices and at the same time to particularly pay attention to the game for frequently being-experienced injury prevention.

CROSS 공법을 이용한 폐수의 생물학적 처리에 관한 연구

This study aims to develop using a continuous removal of organic and settling solid(CROSS) to increase the efficiency of aeration system for wastewater treatment. To solve many problems of the conventional activated-sludge process, authors suggested a new CROSS model in conjunction with aeration systems in 1996. This system is characterized by utilizing an intensive aeration pipe with inlets at the lower portion and outlets at the higher portion in an aeration tank. Through the experiments on CROSS process, the average removal efficiences of BOD, COD_(Mn), SS, T-N and T-P were showed 98.8%, 93.9%, 98.0%, 71.3% and 49.8%. The average DO (Dissolved-Oxygen) concentration was constantly maintained at 8.0 mg/L by the intensive aeration which was accompanied by rapid reduction of BOD. Degradation of the organic matters in sewage then continued for the whole aeration period. The process demonstrated that it was very adaptive without seeding and returning the sludge. Compared to the activated sludge system, the system was very flexible for the continuous flow treatment. This preliminary assessment showed that the porous media in CROSS reactor is viable for the sewage treatment, since the porous media under the intensive aeration achieves acceptable effluent quality.
