개방 시스템 응용을 위한 개선된 ASN.1 컴파일러 설계 및 구현
김홍열,임제택 대한전자공학회 1996 전자공학회논문지-A Vol.33 No.3
Syntax notation one (ASN.1) defined by ITU-T and ISO, is a formal abstrct specification language which has been widely used in international standards specifiation to inteconnect distributed open systems. It si necessary to have well defined encoder/decoder modules which taranslate ASN.1 datum to BER octets stream to interconnect distributed open systems. In this paper, we designed and implemented a new ASN.1-to-C compiler, called HYASNC (hanyang ASN.1-to-C), which atutomatically translates and ASN.1-to-C compiler, called HYASNC (hanyang ASN.1-to-C), which automatically translates an ASN.1 specification into C-language BER encoders and decoders with simple and neat I/F for the defined ASN.1 data types, and enhanced BER (basic encoding rules)encoding/decoding libraries, called HY(hanyang)BER library, and useful utility functions. And this paper discusses HYASNC compiler, HY BER runtime library's design and implementation principles, and also evaluates the perfomrance of HY BER library and the interoperability with other ASN.1 compilers.

Menopause is an event common to all women. For some women, it is not difficult, but for many it arrives with complication, both physiological and psychological. Although there is perhaps no gynecologic disorder in which the indication for hormone therapy is more rational than in the treatment of typical climacteric symptoms, especially the vasomotor group, it must be remembered that many symptoms frequently observed in menopausal women are not directly due to the endocrine readjustments of this period but are more logically explained as due to environmental and psychogenic factors. Estrogen therapy is indicated for the control of acute symptoms of the hot flush and insomnia. If treated soon after onset with adequate dosage, the symptoms can usually be controlled rapidly. As the menopausal woman is not totally estrogen deficient, but only relatively deficient in respect to reproductive capacity. some women will not need constant low-dose estrogen replacement therapy as indicated in the premature menopausal patient. Prophylactic estrogen therapy for the prevention of arteriosclerotic cardiovascular disease may be needed. For the patient at risk for osteoporosis, low-dose prophylactic estrogen therapy may be needed. The action of estrogen on bone is to prevent calcium resorption, and there is little evidence that it will stimulate new bone formation. The two cardinal principles of hormon therapy are most important in such long-term treatment, as little "as necessary to control symptoms over as short as possible a duration" Consequently, today a healthy fifty-year-old women can resonably expect to live for another thirty to forty years.
삽목시기, 삽상온도 및 생장조절제처리가 낙우송의 발근에 미치는 영향
김홍열,박정주,이영주,고재철 대구효성가톨릭대학교 응용과학연구소 1997 응용과학연구논문집 Vol.6 No.1
낙우송의 경삽시 발근 및 캘루스형성에 미치는 삽수채취시기, 삽상온도 및 여러 가지 생장조절물질의 효과에 대하여 조사하였다. 4월 3일, 4월10일, 4월 17일, 5월 22월에 삽수를 채취하여 발근 및 캘루스형성에 미치는 영향을 조사한 결과 발근은 4월 17일이 가장 좋았으며 그 다음이 4월 10일 이였다. 캘루스형성율의 경우 4월 17일이 가장 좋았으며 다음이 5월 22일 이였다. 삽상온도는 삽수채취시기에 관계없이 20℃가 발근 및 캘루스 형성에 가장 효과적이었다. NAA, IAA, S-07처리에 의해서 캘루스형성이 촉진되었다. This experiment was carried out to evaluate the effects of cutting date, bed temperature and growth regulators on the rooting of stem cuttings of Taxodium distichum (L.) Rich. As a result of investigation for the rooting and callus formation of stem cuttings which were cutted at 3, 10, 17 April and 22 May respectively, rooting cutted at 17 April was best and 10 April in the next. And callus formation rate was highest at 17 April and 22 May in the next. Under 20℃ bed temperature, rooting and callus formation were better than 30℃ regardless of cutting dates. Callus formation was promoted by NAA, IAA, and uniconazole treatments.

우리나라 대부분의 공동주택에 사용되고 있는 콘크리트는 재료의 특성상 콘크리트면에 직접 충격이 가해짐에 따라 발생하는 충격음(고체전달음)이 인접세대에 쉽게 전달되는 특성을 지니고 있어, 현행 우리나라에서 적용되 고 있는 바닥구조로서는 근본적으로 해결하기가 쉽지 않다. 따라서 본 연구에서는 이러한 문제점을 해결하기 위하여 폐타이어를 Cutter로 분쇄하고 이를 수성바인더로 접착하여 제조한 바닥충격음 저감재 의 차단성능 및 바닥충격음 저감재로서 요구되는 물리적 성능평가(건조수 축, 냉·온반복성능, 탄성계수, 단열성능 등)와 화학적 성능평가(인체유해 성, 콘크리트와의 반응성 등)를 실시하고 개선사항을 제시하므로서 효과적 인 활용이 이루어지도록 하는 것을 본 연구의 목적으로 하였다.
