  • Purpose: To study the difference between refractive errors obtained from manifest refraction (MR) and cycloplegic refraction (CR) in first-time spectacle wearers. To study the difference between manifest refractive errors and cycloplegic refractive errors in first-time spectacle wearers. Methods: From January 2002 to December 2002, manifest and cycloplegic refractions were carried out on the patients who visited an ophthalmology clinic for a spectacle prescription for the first-time. The patients were 509 male and 499 female patients aged between from 3 to 15 years old. Results: The cycloplegic refraction showed a less myopia and a more hyperopia compared with the non-cycloplegic refraction. The differences were more in female patients. The CR showed a less myopic and a more hyperopic refractive errors than the MR. The differences were more in female patients. The average results from a pre- and a post-cycloplegic refraction showed a reduction of -0.22D in male, and -0.20D in female for the myopic group. For the myopic group, the myopic refractive errors by MR were -0.22D in male and -0.20D in female higher than the refractive errors by CR. Hyperopic group showed an increase of +0.37D in male, and +0.56D in female. For hyperopic group the hypropic refractive errors by CR were +0.37D in male and +0.56D in female higher than the refractive errors by CR. This difference between the results of a preand a post-cycloplegic refraction was more if the patients were younger. This difference between refractive errors by MR and by CR showed the younger the more and the proportions of pseudo-myopia and or latent hyperopia were also higher with younger patents age. The amounts of with-the-rule astigmatism and the oblique astigmatism were increased for the post-cycloplegic refraction in the CR refraction. Simple astigmatism reduced, but there was no difference found in the amount of astigmatism. The prevalence of simple astigmatism reduced, but there was no difference in the amount of astigmatism. Conclusions: The difference between manifest refraction and cycloplegic refraction was more in younger group. The difference of refrative error between by MR and CR increases with ageing decrease. Pseudo-myopia and latent hyperopia was also found in the younger group. Simple astigmatism reduced after cycloplegic refraction, there was no difference found in the amount of astigmatism. The prevalence of simple astigmatism reduced, but there was no difference in the amount of astigmatism.

  • Housing owners in Korea have a variety of tax advantages such as income tax exemption for the imputed rent of owner-occupied housing, exemption from the capital gains tax and deduction of the estate tax for one-house households. These tax reliefs for housing owners not only conflict with the principle of horizontal and vertical equity, but also lead to resource misallocation by distorting the housing market, and thus bring about regressive distribution effects. Particularly in the case of Korea with its imperfect capital market, these measures exacerbate the inter-class inequality of housing ownership as well as inequalities in wealth, by causing the affluent to demand needlessly large housing, while the poor and young experience difficulties in purchasing residential properties. Therefore, the Korean tax system must be altered as follows in order to disadvantage owner-occupiers, especially those owners of luxury housing. These alterations will promote housing-ownership, tax burden equity, efficiency of resource allocation, as well as the desirable distribution of income. First, income tax deductions for the rent payments of tenants are recommended. Ideally, the way of recovering the fiscal equivalence between the owner-occupiers and tenants is to levy an income tax on the former's imputed rents, and if necessary to give them tax credits. This, however, would be very difficult from a practical viewpoint, because the general public may perceive the concept of "imputed rent" as cumbersome. Computing the imputed rent also entails administrative costs, rendering quite reasonable, the continued exemption of imputed rent from taxation with the simultaneous deduction in the income tax for tenants. This would further enhance the administrative efficiency of income tax collection by easing assessment of the landlord's income. Second, a capital gains tax should be levied on the one-house household, except with the postponement of payments in the case that the seller purchases higher priced property. Exemption of the capital gains tax for the one-house household favors those who have more expensive housing, providing an incentive to the rich to hold even larger residences, and to the constructors to build more luxurious housing to meet the demand. So it is not desirable to sustain the current one-house household exemption while merely supplementing it with fastidious measures. Rather, the rule must be abolished completely with the concurrent reform of the deduction system and lowering of the tax rate, measures which the author believes will help optimize the capital gains tax incidence. Finally, discontinuation of the housing exemption for the heir is suggested. Consequent increases in the tax burden of the middle class could be mitigated by a reduction in the rate. This applies to the following specific exemptions as well, namely, for farm lands, meadows, woods, business fields-to foster horizontal equity, while denying speculation on land that leads to a loss in allocative efficiency. Moreover, imperfections in the Korean capital market have disallowed the provision of long term credit for housing seekers. Remedying these problems is essential to the promotion of greater housing ownership by the low and middle income classes. It is also certain that a government subsidy be focused on the poorest of the poor who cannot afford even to think of owning a housing.

  • Regarding the [Government Organization Act; which is legislated on 19th November, 2014] Korea Coast Guard(KCG) has been re-organized and belong from Korea Coast Guard shall be established under the Minister of Oceans and Fisheries to Ministry of Public Safety and Security. Furthermore, National Police Agency(NPA) Commissioner has the right for administer duties concerning investigation and information by succession from Korea Coast Guard Commissioner. That means that main rule has been moved from prior KCG to Ministry of Public Safety and Security(MPSS) and NPA currently which is dual structure. Meanwhile, This kind of organization change has been effective to investigative agency which exert KCG's call of duty and causes needs of variety problems. In other words, There are quite huge changes such as KCG's reduction of their work, call of duty and re-organization regarding revised government organization act. However this change - including re-organization by government, was not able to take current MPSS's special features such as organization specialty and legal rights. It means, the current change has not been taken present law system CRIMINAL PROCEDURE LAW and there was no preparation to stable maritime police authority action as well. To sum up, this revised GOVERNMENT ORGANIZATION ACT is supposed to provide total, quick security service by establishing strong disasters and safety control tower. However they only contains few area such as organization revision regarding 'Sewol Ferry Disaster', they was not able to contain the other parts of Society. Therefore, in this article I would like to check the part of re-evaluation of current change made by KCC's organization revision. It is supposed to provide better legal stability by making clear of work area by government agencies who acts maritime police authority.
