The soybean [Glycine max (L.) Merr.], an edible legume, has a high protein content in both its hay and grain, so it is often used as a supplement for other forages that have a deficient protein concentration. Therefore, this study investigated the forage quality and yield in the case of mixed planting of soybean and corn. The forage yield and quality were assessed for three cropping patterns: soybean mono planting, corn mono planting, and mixed planting of soybean and corn. For planting, this study used a forage corn cultivar, Kwangpyeongok, and three recombinant inbreed lines, W2, W4, and W11, selected from Glycine soja (PI483463)${\times}$G. max (Hutcheson). The mixed planting of soybean and corn produced a higher forage yield than the corn mono cropping. The crude protein and crude fat content were also increased with the mixed planting of soybean and corn when compared with the corn mono cropping. Some decrease of ADF and NDF, and increase for RFV in mixed planting of soybean and corn than corn mono cropping. Therefore, the results show that mixed planting of soybean and corn is an effective cropping system to improve the forage quality.

서진동,조현,김민수,송종태,이정동 한국육종학회 2019 Plant Breeding and Biotechnology Vol.7 No.2

Soybean [Glycine max (L.) Merr.] cultivar ‘Chookdu 1’ (registration number: No. 7159) and ‘Chookdu 2’ (registration number: No. 6758) were developed as forage soybean cultivars at Kyungpook National University, Republic of Korea. They were grown in tests over three years and compared with a commercial seed cultivar for seed yield and forage productivity planted in the same row in mixed plantings with corn. Chookdu 1 and Chookdu 2 are tall, indeterminate growth habit selections from a cross between wild soybean (Glycine soja Sieb. & Zucc.), ‘PI 483463’, and cultivated soybean, ‘Hutcheson’ (PI 518664). The plant height of Chookdu 1 and Chookdu 2 were 80.9 cm and 81.4 cm, respectively, compared to 54.7 cm for the ‘Pungsannamul’ commercial seed check. The three-year seed yield of Chookdu 1 and Chookdu 2 was 2.0 and 2.2 t/ha, respectively, and not significantly different from Pungsannamul at 2.4 t/ha. Of the two cultivars Chookdu 2 averaged the most total forage fresh weight (65.0 t/ha). The three year mean forage yield of mixed-planting of corn and Chookdu 2 and Chookdu 1 was 10.4% and 3.8% greater, respectively, than corn monoculture. Results show Chookdu 1 and Chookdu 2 are suitable soybean cultivars for mixed planting in the same row with corn to improve forage yield. They should be useful as parents to use in breeding to develop forage-type soybeans of high quality and yield for use in livestock feed.

Soybean has a high protein content in both its hay and seed. Studies have shown that the mixed cropping of corn and soybean improved forage yield and quality. The objective of this study was to select soybean germplasm suitable for mixed cropping with corn on the same row to produce better forage yield and quality. Eleven soybean lines selected from previous evaluations were used in this study. Soybeans were planted with corn on the same row at 10 cm intervals. The planting rate in hills was one corn plant and three soybean plants. The fertilization and time of forage harvest were based on the recommendations for forage corn production. The results showed that in corn–soybean mixed cropping, the forage yield increased by about 19%, the silage protein content increased by 1%–2%, the percentage of acid detergent fibers and neutral detergent fibers decreased, the total digestible nutrients increased, and the acetic acid content decreased. Therefore, the selected soybean lines were suitable for mixed cropping with corn to produce high quality forage and/or as breeding material for the development of forage soybean varieties. Based on this study, we suggest that the agronomic traits of soybean needed for mixed cropping with corn on the same row for forage are as follows: soybean should 1) have the ability to grow well under the corn canopy, 2) have lodging tolerance for ease of mechanical forage harvest, 3) develop to the full pod stage at the time of harvest for increased protein content, and 4) have no adverse effects on corn growth to maintain a high forage yield.

Post-Annealing Effects on Optical Properties of GaAs/AlGaAs Quantum Dots Grown by Droplet Epitaxy

서유량,강태인,김종수,송진동,이상준,김희대 한국진공학회 2023 Applied Science and Convergence Technology Vol.32 No.1

The effects of annealing temperature on optical properties for low-temperature growth (LTG) GaAs/AlGaAs quantum dots (QD) were investigated in this study. The LTG GaAs QDs were annealed at temperature of 650, 700, and 750 ∘C. From the photoluminescence (PL) results, we found that the PL intensity was enhanced as the annealing temperature was increased and the emission wavelength blue-shifted with increasing annealing temperature. We confirmed that the crystal quality of LTG QD could be improved due to the thermal quarrying effect. The GaAs QD size could be smaller due to Ga out-diffusion and Al inter-diffusion during the thermal annealing process. In photoreflectance spectra, the Franz-Keldysh oscillations above the GaAs band gap become stronger with increasing annealing temperature. The interface electric field strength also increases due to the decrease in the defect density. We thus found that the defect density could be decreased by increasing the annealing temperature.

채용시 건강진단 폐지 후 배치전 건강진단의 실태

서춘희,이종태,김대환,손병철,이창희,김휘동,안진동 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.3

목적: 산업안전보건법 개정 후 배치전 건강진단의 실시 현황 및 보건관리자의 인식도를 파악하고자 하였다. 방법: 부산과 경남에 위치하는 특수건강진단기관 2개소 에서 2006년 1월 1일에서 2006년 12월 31일까지 배치전 건강진단을 받은 근로자 6,507명을 대상으로 배치전 건 강진단서 판정결과를 검토하였다. 건강관리구분 유소견자 판정을 받은 근로자 330명을 대상으로 전화인터뷰를 시도하여 성공한 185명을 최종 연구 대상으로 하였다. 그리고 동 기관에서 관리하고 있으며 특수건강진단을 실시하는 보건관리대행 사업장 중에서 169개의 사업장 보건 관리자를 대상으로 2007년 5월 1일에서 9월 30일까지 설문조사를 하였다. 결과: 근로자 전화 인터뷰 조사에서 배치전 건강진단 결과 질환 유소견 판정때문에 채용이 거부된 사람은 51명 (27.4%)이었다. 보건관리자를 대상으로 한 설문조사에서 채용시 건강진단의 폐지를 모르는 사업장이 39개(23.1%)였다. 배치전 건강진단을 근로자 채용결정 후 부서배치 전에 실시하는 사업장 73개(43.2%)중에서 그 결과를 부서배치에 활용한다고 응답한 사업장이 63개 (37.3%)였다 질환유소견 판정을 받았을 때 고혈압,당뇨병,고지혈증 등 만성 칠환이 있는 경우 각각 20개(11.8%),21개(12.4%),22개(13.0%) 사업장에서 근로자를 고용하지 않는다고 답했고,업무상 질병과 관련된 청력이상,요추부 방사선 이상소견이 있을 때 각각 76개 (44.4%),75개(43.8%) 사업장에서 근로자를 고용하지 않는다고 답했다. 결론: 채용전 건강진단이 폐지되고 배치전 건강진단에 대한 법 조항이 개정되었음에도 불구하고 사업장에서는 법규에 대한 이해가 불충분하여 여전히 배치전 건강진단이 취업시 불건강자를 가려내는 목적으로 이용되고 있으며,업무 적합성 개념에 대한 이해가 불충분하였다. 따라서 사업주는 배치전 건강진단 실시시기를 준수하고 건강 진단 기관에 배치 예정 업무에 대해 구체적인 정보를 제공하여야 한다. 정부에서는 법규 개정 후 홍보에 힘쓰고,법규 시행 후 적절한 정책 평가도 병행하여야 한다. Objectives: We investigated the status of the preplacement medical examination after the revision of the industrial safety and health law on Oct. 7, 2005 by the Ministry of Labor. Methods: Preplacement medical certificates of 6,507 recruits issued by two hospitals in Busan, Kyeongnam Province from Jan. 1 to Dec. 31,2006 were reviewed. Telephone interviews were performed to the recruits with disease and self-reported questionnaires were administrated to health and safety personnel from May 1 to Sep. 30, 2007. Results: Interviews were conducted with 185(56.1 %) recruits with disease, 51(27.4%) of whom were rejected for employment due to the preplacement medical certificate. The questionnaire survey for the health and safety personnel revealed that 39(22.9%) personnel were unaware of the annulment of the preemployment medical examination. Eighty(48.8%) of the health and safety personnel answered that they performed a preplacement medical examination after employment, and 63(37.3%) made a practical application of the workers' placement. The recruits with chronic conditions were refused employment: 20 (11.8%) due to hypertension, 21 (12.4%) diabetes mellitus and 22(13.0%) hyperlipidemia. The recruits with work-related diseases were also refused employments: 76(44.4%) due to lumbar spine abnormality and 75(43.8%) hearing loss. Conclusions: Despite the annulment of the pre-employment medical examination, a preplacement medical examination was often used to discriminate among healthy and diseased recruits. Employers must respect the law for the point of time of the preplacement medical examination and the payment of cost. The government should publicize the revision of the objectives of the law. We suggest that health professionals elucidate the job fitness through the development of the assessment tools and maintain the confidentiality of recruits.

간세포암을 치료하는 방법 중에서 경동맥 화학 색전술 (Transarterial chemoembolization TACE)은 종양의 괴사를 일으켜 치료하는 방법으로 수술이 불가능한 간세포암 환자를 치료하기 위해서 사용되고 있으나 정상적인 조직에도 손상을 일으켜 구역, 고열과 우상복부 통증, 간 기능저하, 담낭염, 췌장염, 간성 혼수 및 총수담관 폐쇄, 폐동맥 색전 및 뇌 경색 등의 부작용을 야기할 수 있다. 이 중에서 뇌 경색이나 하지마비 등의 신경학적인 부작용은 드문 편이나 발생시 심각한 후유증 및 영구적인 장애를 야기할 수 있으므로 즉각적이고 효과적인 치료가 요구된다. 본 증례에서는 간세포암으로 진단 후 반복적인 경동맥 화학 색전술 및 고주파 열치료 시행을 받은 환자가 우측 7번 늑골로의 전이를 진단 받았고, 이에 대한 치료를 위해 방사선 치료를 시행하였으나 효과를 보이지 않아 늑간동맥을 통한 경동맥 화학 색전술을 시행하였다. 환자는 시술 이후 흉골 이하의 감각 및 운동저하를 호소하였고 신경학적 검사 및 자기공명 영상검사를 시행한 결과 허혈성 척추손상으로 인한 척수병증으로 진단하여 스테로이드 펄스요법을 5일간 시행하였고 이후 지속적인 재활치료 및 근 이완제 및 프레가발린을 사용하였다. 이후 환자는 운동 능력은 호전되었으나 감각이상 및 경직은 유지되고 있는 상태이다. 국내에서는 경동맥 화학 색전술 이후에 발생하는 신경학적인 장애에 대한 보고는 드물고 국내 문헌을 검토한 바에 의하면 간세포암의 우측 늑골로의 전이에 대한 색전술 시행 이후 발생한 양측하지마비가 발생한 증례는 보고된 바가 없어 이에 저자들은 늑골로 전이된 간세포암의 경동맥 화학 색전술 시행 후 발생한 양측하지 마비 1예를 경험하였기에 보고하는 바이다.
