        Evaluation of Growth, Flowering, and Chlorophyll Fluorescence Responses of Viola cornuta cv. Penny Red Wing according to Spectral Power Distributions

        장인태,이재환,신은지,남상용 인간식물환경학회 2023 인간식물환경학회지 Vol.26 No.4

        Background and objective: The genus Viola, a member of the Violaceae family, is renowned for its ornamental flower crops. Additionally, Viola species are relatively pest-resistant and easy to manage. They are widely used in gardens, and some oftheir flowers are even edible. In this study, our focus was on V. cornuta cv. Penny Red Wing (hereinafter referred to as‘Penny Red Wing’), an experimental plant chosen for its high ornamental value and rapid growth. Methods: We applied a purple light-emitting diode (LED) and three types of white LEDs with varying color temperatures:3000, 4100, and 6500 K, respectively, as artificial light sources. Notably, a purple LED has a far-red wavelength (700-800nm) ratio of approximately 17.6% in their spectral power distribution. Results: The findings indicated that several parameters exhibited higher values under purple LED: shoot size parameters,shoot biomass, moisture content of shoots and roots, photochemical reflectance index (PRI), modified chlorophyllabsorption ratio index (MCARI), total number of flowers, flower size parameters, scent score, Fv/Fm, and PIABS. However,the 6500 K white LED led to higher evaluations of root length, number of shoots and leaves, root biomass, moisture contentof shoots and roots, Fv/Fm, and PIABS. Nevertheless, it was observed that shoot growth was relatively hindered, and theflowering responses were inadequate under the 6500 K white LED, suggesting their unsuitability for the mass productionof ‘Penny Red Wing’. Furthermore, the 3000 and 4100 K white LEDs were also deemed unsuitable for cultivating ‘PennyRed Wing’ due to their lower cultivation efficiency. Conclusion: ‘Penny Red Wing’ was evaluated as having superior growth, flowering, and chlorophyll fluorescence responsesunder purple LED, indicating that the far-red wavelength had a more pronounced effect compared to the green wavelength(500-600 nm). Therefore, we recommend cultivating this cultivar under purple LED, which include the far-red wavelength.

        The main treatment of acute infectious disease in surgical patient is an infusion of antibiotics, although an effect of antibiotics has been deteriolated in chronic status. Therefore many clinician has used combined therapy of antibiotics and anti-inflammatory drugs such as adrenal cortical hormone or non-steroid anti-inflammatory drugs. Adrenal cortical hormone has not been used due to a lots, of compltcations of gastro-intestinal tract and brain. Acetylsalicylic acid and phenylbutazone has long been used as anti-inflammatory drugs. Phenylbutazone derivatives are activated by -acid base, while Solantal is activated by alkali base, which has been made at Fuzizawa Pharmaceutical Co. as benzothiazoline derivatives, namely Tiaramide. Clinical studies of Solantal has been made with 45 patients at Surgical. department of National Medical Center, Seoul, Korea. Most of patients were able to take of food early after surgery. Average daily dosage of Solantal were ranged from 300mg to 600mg for shortest 3 days to 20 days. It has been effected against pain-after surgery with 70~80%. In anti-inflammatory effect, it could not been studied by difficult measure of Solantal effect in surgical patient. Side reaction of Solantal was minimal. with gastrointestinal trouble(0.5%) and itching sensation(0.2%). There has been nothing of complication during long standing use.

        In this paper, the image binarization method using standard specifications of the vehicle license plate to recognize characters on the plates is proposed. The global binarization method that had a threshold over entire image pixels cannot acuratelly binarize in case that local average brightness are varied to each plates characters regions. The proposed method uses the characters regions in the standard specifications of the korean vehicle license plates as binarization blocks. For installed cameras on national roads and parking areas, the computer simulation results showed average characters recognition rate about 5% higher than the otzu global binarization method.

        支給利子에 대한 損金規制

        張仁太(In Tae Chang) 한국세법학회 2001 조세법연구 Vol.7 No.-

        오늘날 다양한 금융기법이 확정손익과 미확정손익의 구별을 무너뜨림에서 한 걸음 더 나아가 근본적으로 부채와 자본의 구별은 그 자체가 상대적인 개념에 불과하고, 일반론으로 돌아가면 부채와 자본을 대치시키는 기본 축은 투자위험과 기업운영에 대한 지배권 두 가지 뿐이라고 할 수 있는데도 법인기업의 입장으로 보아서는 자기자본에 의한 자금의 조달보다는 타인자본에 의한 자금의 조달방법을 선호하여 왔다. 현행 세법은 배당과 지급이자에 대해 중립성을 유지하는 방법으로 배당에 대해 손금산입을 부인하고 지급이자에 대해서는 손금산입을 인용하나 일정한 경우에 있어서 이를 불산입하는 방법을 취하고 있다. 본 논문에서 현행 법인세법상 지급이자에 대한 손금규제의 취지와 그 내용 및 문제점을 살펴보면, 지급이자의 손금부인에 대한 규정이 동시에 적용되는 경우에는 일정한 순서 및 방법으로 적용되어야 하므로 법인세법에서 정하고 있는 지급이자의 처리방법을 살펴보고 이어서 채권자불분명 사채이자, 지급받는 자가 불분명한 채권ㆍ증권의 이자와 할인액, 기준초과차입금에 대한 지급이자, 건설자금이자, 타 법인의 주식 및 임야 등 특정용도 부동산 등에 관련한 차입금이자, 비업무용 부동산ㆍ비업무용 동산ㆍ특수관계자에 대한 업무무관가지급금에 관련한 차입금이자 및 기타 관련문제로서 특수한 이자 등에 대하여 고찰한다. In today the various financial know-how is advanced a step forward from the collapse of distinction of fixed loss & profit and unfixed loss & profit and, the distinction of debt and capital is nothing but relative concept itself fundamentally and if returns to general theory and notwithstanding the basic axes to replace debt and capital is only two controlling power of investing risk and enterprising operation but from the position of corporate enterprise has been preferred procurement of funds by outside capital than the funding by equity capital. To look back the reason from aspect of the tax law, the current tax law takes the manner to subtract the total loss from the total income in deciding assessable income and, as per the dividend to shareholders by the enterprise it is not allowed as loss whereas it is allowed as loss as per the interest payable to the loan. Since therefore, it would be preferred from the position of a corporation by the method to reduce the assessable income in calculation of income by the corporation and therefore, the method by outside capital accompanied by interest will be preferred. There is a big problem as an enterprise as the interest burden to loan is not less and whether the interest payable will be by acquisition cost of the fixed assets or to be disposed as simple cost in the current transaction status as the enterprise taxation cost. Such a problem will be a matter in the essential theory as there is tendency used as evading means in the tax law by counting of loss into interest paid. It is therefore, that is required by the neutrality in the taxation law about dividend & interest paid will also be natural. As for method of maintaining of the neutrality, there will be such method to allow the dividend as loss and be the method to do disposition of dividend & interest paid as the same by not allow the interest paid as a loss however, the current tax law disposes the dividend & interest paid as follows: That is to say, it denies calculation of loss of dividend but allows for calculation of loss of the interest paid and in a certain case, it takes the method not counting it in. Since therefore, under this thesis to look back the purport of loss restriction, the details and the problems of interest payable in the current Corporate Tax Law and, if the provision of denial of loss to interest paid it has to be applied under a certain order and method, to look into the disposing method of interest paid as set forth by the Corporate Tax Law and is to give consideration to interest of debenture the creditor is not clear, the credit of the person to be paid is not clear, the interest & discount amount of securities, the interest paid to loan in excess of the standard, the interest to construction fund, the interest to loan related to such specific use as stock and forest of other corporation, the interest to loan in respect to provisional payment having no relation with business of specially related person, real estate not for business, personal property not for business and special interest as related problems.

        다중 카메라를 이용한 실시간 객체 추적 방법

        장인태(In-Tae Jang),김동우(Dong-Woo Kim),송영준(Young-Jun Song),권혁봉(Hyeok-Bong Kwon),안재형(Jae-Hyeong Ahn) 한국산업정보학회 2012 한국산업정보학회논문지 Vol.17 No.4

        최근 보안 감시 분야에서 영상처리를 이용한 객체 추적에 관한 연구가 활발히 이루어지고 있다. 기존 여러 대의 카메라를 이용한 보안 감시 시스템은 각각 독립적으로 운영되었다. 따라서 추적 객체가 다른 카메라의 감시영역으로 이동 시 계속해서 추적이 어려웠다. 이 문제를 해결하기 위해 본 논문은 다중 카메라에서 객체의 이동방향에 따라 자동으로 카메라의 제어권을 변경하는 방법을 제안한다. 제안방법은 객체를 검출하고 객체의 색상 정보와 방향 정보로 객체를 추적한다. 색상 정보는 hue를 이용하고 방향 정보는 광류를 이용하여 획득한다. 이때 광류는 전체 영상이 아닌 객체가 검출된 영역에만 적용하여 계산량을 줄여 실시간 추적이 가능하게 한다. 또한, 자동으로 객체를 추적함으로써 기존 카메라를 이용한 보안 감시 시스템의 불편함을 해결할 수 있다. Recently, the study about object tracking using image processing has been active in the field of security and surveillance. Existing security and surveillance systems using multiple cameras have been operating independently. Thus, the chase was difficult when the tracking object move to other monitored areas. In this paper, we propose the way to change the control of camera automatically following the moving direction of objects in multiple cameras. The proposed method detects the object and tracks the object using color information and direction information of object. The color information obtains using the hue and the direction information obtains using the optical flow. At this time, the optical flow is detected for the entire image area of an object that is not applied only to reduce the computational complexity makes it possible to track in real time. In addition, it can be solved to inconvenience of security surveillance system to use existing camera by tracking an object automatically.
