        The purpose of this study was to evaluate winter annual forage crops for yield, and horse palatability under horse grazing during the fall and spring in Jeju. The winter annual forage crops such as Italian ryegrass(IRG), rye, and oat were planted in randomized block design in October 30. The horse grazing was initiated on March 17 of the following year. At the first cutting, the dry matter yield of rye was the highest with 4,600 kg/ha compared to the IRG and oat (p<0.05). But there were no significantly different in the yield of winter annual forage crops after the second and third harvests. The total dry matter yield showed rye 12,593 kg/ha, IRG 10,941 kg/ha, and oat 9,424 kg/ha respectively. The horse intake duration of the IRG was significantly higher than the oat and rye (p<0.05). In the first grazing and the second grazing, the intake duration of the IRG was 853.2 seconds and 989.4 seconds, respectively, with oat at 147.6 seconds, and 73.0 seconds, and rye at 89.4 seconds, and 33.18 seconds. The intake duration of IRG was longer than that of oat and rye (p<0.05). The intake rate of the IRG was 60.0% in the first and 82.8% in the second, and the average intake rate was 71.4%. When considering the maintenance of pastures and the palatability of horses, the IRG is the most suitable forage crop in winter annual forage crops in Jeju.

        본 논문에서는 우리나라에서 2019년 7월부터 시행된 특허법 상징벌적 손해배상제도 관련 국내외 판례 및 우리나라 입법 연혁 등에 비추어 특허 침해의 고의성 요건과 배상액 산정 시 고려사항을 분석하였다. 먼저, 특허 침해에 대한 징벌적 손해배상제도를 예전부터 도입한 미국의 사례를 분석하였다. 특히 미국은 최근 30년간 판례에 의해 징벌적 손해배상 기준에 큰 변화가 있어왔는데, 징벌적 손해배상의 대상이 되는 악의적, 고의적 특허 침해의 의미에 초점을 맞추어 판례 변화를 분석하였다. 또한, 미국 판례와 모델법에서 언급된 배상액 산정 시 고려사항과 우리나라 특허법에 도입된 고려사항을 비교하였다. 마지막으로, 징벌적 손해 배상 도입과 관련한 우리나라의 입법 연혁을 살펴봄으로써 고의적 특허 침해의 의미 및 배상액 산정 시 고려사항에 대한 입법 의도를 추론하였다. 고의적 특허침해를 위해서는 침해자에게 유효한 특허의 보호범위에 속하는 발명을 실시하고 있다는 인식이 필요하다. 이를 위해 특허권자는 경고장이나 특허심판원의 권리범위확인심판 심결 등을 활용할 수 있을 것이다. 침해자는 특허의 무효성 또는 비침해 판단을 담은 전문가의 의견이나 경고장의 주장을 반박하는 답변서 등을 통해 대응할 수 있어야 할 것이다. 다만, 침해자에게 최소한의 선행기술분석 의무를 지우기 위해서는 중과실에 의한 침해 또한 징벌적 손해배상의 대상에 포함시키는 것이 합리적일 것이라고 고려된다. 또한, 징벌적 손해배상액을 산정할 때 판사에게 여러 가지 요소를 종합적으로 분석하도록 재량을 부여하는 것이 필요하다. 징벌적 손해배상이 무고한 사람에게 미치는 부정적 영향, 소송당사자로서의 침해자의 행동 또는 침해자가 침해 행위를 숨기려 했는지의 여부 등의 고려사항을 추가 하는 것도 생각해볼 수 있을 것이다.

        This study was conducted to suggest the new grassland grade system on evaluating the grassland status. The grassland status has been evaluated based on the forage yield (good, fair and poor) by municipal authorities. The grassland grades by current system were 19 good, 11 fair and 11 poor among the 41 grassland farms from 6 provinces. This evaluation result differed greatly from the result of actual measurement of forage yields which showed all poor. The big difference was resulted from failing the reflection of the various characteristics, such as different seasonal growth and harvest frequency. Furthermore, the lack of consistent examining date and method added the inaccuracy of current grassland grade system. The new grassland grade system based on the grassland vegetation ratio (grass, weed and bare soil) was initially designed into 6-grade system (1st; 100~80%, 2nd; 79~60%, 3rd; 59~40%, 4th; 39~20%; 5th; 19~1% and 6th; 0% on the basis of grasses proportion), but later was changed into 4-grade system (1st, 2nd, 3rd, and 4th grades are 70% or more, 50% or more, 50% or less, and 0% of forage proportion, respectively) after reflecting the opinion of grassland farms and municipal authorities. Re-evaluation on the grassland status using the 4-grade system resulted in the total 80% consisted of 2nd, 3rd and 4th grade which means most grasslands needs the partial reseeding or the rehabilitation of entire grassland. Pictures and schematic diagrams depicting the 4-grade system were presented to improve the objectivity of evaluation. The optimal time for assessing grassland status is fall when plant height 20~30 cm. Conclusively, the 4-grade system is an efficient method for all non-professionals including grassland farms or municipal authorities in assessing the grassland status. To apply this system to the field, the institutional arrangements such as amendment of grassland act should take place in advance.

        This study was conducted to evaluate feed value of imported hays and examine current situation of species and hay grade. To evaluate the quality of the imported hay, 133 pieces including 9 species of roughage types were collected at the national hay importers, the TMR companies and livestock farms from 2016 to 2018. The quality grades of imported hay were 3~4 and most imported hay were considered to had low. The ADF, Ash, TDN and DDM in feed composition of alfalfa by quality grades presented significant differences(p<0.05). The quality grade on alfalfa was not similar to the actual quality grades calculated through feed composition. The feed composition of grasses by quality degrees presented significant differences in all contents except DM and CP (p<0.05). As the distributed grasses of the unmarked quality grade was low quality and accounted for 49%, it is urgent to present quality standards based on feed composition. As these results, the grades of imported hays were lower than the marked quality grades. Therefore, the imported roughage’s(hay) price that considered to only quality grades on the marked imported roughages(hay) package can cause a loss to the livestock farms as economic damage. An institutional arrangement should be established to review the quality grades of imported hay.

        In this study, whole crop rice samples were used to develop near-infrared reflectance (NIR) equations to estimate six forage quality parameters: Moisture, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), Ash and relative feed value (RFV). A population of 564 whole crop rice representing a wide range in chemical parameters was used in this study. Undried finely chopped whole crop rice samples were scanned at 1 nm intervals over the wavelength range 680–2500 nm and the optical data recorded as log 1/Reflectance (log 1/R). NIRS calibrations were developed by means of partial least-squares (PLS) regression. The correlation coefficients of cross-validation (R2 cv) and standard error of cross-validation (SECV) for whole crop rice calibration were 0.98 (SECV 1.81%) for moisture, 0.89 (SECV 0.50%) for CP, 0.86 (SECV 1.79%) for NDF, 0.89 (SECV 0.86%) for ash, and 0.84 (SECV 5.21%) for RFV on a dry matter (%), respectively. The NIRS calibration equations developed in this study will be useful in predicting whole crop rice quality for these six quality parameters.

        Near infrared reflectance spectroscopy (NIRS) has become increasingly used as a rapid and accurate method of evaluating some chemical compositions in forages. The objective of this study was to evaluate the potential of NIRS, applied to imported forage, to estimate the moisture and chemical parameters for imported hays. A population of 392 imported hay representing a wide range in chemical parameters was used in this study. Samples of forage were scanned at 1 nm intervals over the wavelength range 680-2500nm and the optical data was recorded as log 1/Reflectance(log 1/R), which scanned in intact fresh condition. The spectral data were regressed against a range of chemical parameters using partial least squares(PLS) multivariate analysis in conjunction with spectral math treatments to reduced the effect of extraneous noise. The optimum calibrations were selected based on the highest coefficients of determination in cross validation(R2) and the lowest standard error of cross-validation(SECV). The results of this study showed that NIRS predicted the chemical parameters with very high degree of accuracy. The R2 and SECV for imported hay calibration were 0.92(SECV 0.61%) for moisture, 0.98(SECV 0.65%) for acid detergent fiber, 0.97(SECV 0.40%) for neutral detergent fiber, 0.99(SECV 0.06%) for crude protein and 0.97(SECV 3.04%) for relative feed value on a dry matter(%), respectively. Results of this experiment showed the possibility of NIRS method to predict the moisture and chemical composition of imported hay in Korea for routine analysis method to evaluate the feed value.

        우리나라 특허법은 “자연법칙의 이용성”을 기준으로 발명의 성립성을 판단하고 있다. 또한 법원은 발명의 성립성을 판단할 때 발명에 기술적 특성이 있는지, 발명이 구체적이고 실용적인 효과를 가져다주는지, 혹은 그러한 효과를 가져다주는 기술적 수단이 있는지에 초점을 맞추었다. 하드웨어 내부 또는 외부에서 물리적 변환을 야기하는 경우에 자연법칙의 이용성을 인정한 판례가 있었다. 또한 소프트웨어에 의한 정보처리가 하드웨어 또는 컴퓨터상에 구체적으로 구현되고 있는지를 발명의 성립성 기준으로 삼은 바 있다. 이러한 우리나라의 발명의 성립성은 일본, 미국 및 유럽의 발명의 성립성과 어느 정도 유사한 점을 공유하는 것으로 보인다. 인공지능기술이 발전함에 따라 인공지능기술이 우리나라 특허법 하의 발명의 성립성과 다음과 같은 면에서 충돌할 가능성이 있다. 첫 번째, 인공지능의 메커니즘은 설명하기가 어려워, 명세서에 발명에 대한 구체적인 설명을 요구하는 발명의 성립성 법리를 만족하기 어려울 수 있다. 두번째, 인공지능이 과학, 공학, 컴퓨터 등 기술적 분야뿐만 아니라 언어학, 문학, 경제학 등의 비기술적 분야에 적용됨에 따라 기술적 특성이 있어야 발명으로 인정하는 발명의 성립성 법리와 부딪칠 수 있다. 세 번째, 인공지능이 약한 인공지능에서 강한 인공지능으로 발전함에 따라 추상적 아이디어 또는 인간의 정신적 프로세스를 범용 컴퓨터에 단순히 적용한 것에 불과하다는 이유로 인공지능 발명의 성립성을 부정할 가능성이 있다. 하지만 이러한 잠재적 갈등은 우리나라 특허법의 발명의 폭넓고 유연한 정의에 의해 자연스럽게 해결될 수 있을 것으로 보인다. 입법부에 의해서 주도되는 특허법의 대대적인 개정 없이도, 사법부 또는 특허청이 특허법의 “자연법칙의 이용성” 문구를 유연하게 해석, 발명의 외연을 넓힘으로써 인공지능기술을 포섭할 수 있도록 하는 것이 좋을 것으로 사료된다.

The optimum calibrations were selected based on the highest coefficients of determination in cross validation(R2) and the lowest standard error of cross-validation(SECV). The results of this study showed that NIRS calibration model to predict the moisture contents and chemical parameters had very high degree of accuracy except for barely. The R2 and SECV for integrated winter annual forages calibration were 0.99(SECV 1.59%) for moisture, 0.89(SECV 1.15%) for acid detergent fiber, 0.86(SECV 1.43%) for neutral detergent fiber, 0.93(SECV 0.61%) for crude protein, 0.90(SECV 0.45%) for crude ash, and 0.82(SECV 3.76%) for relative feed value on a dry matter(%), respectively. Results of this experiment showed the possibility of NIRS method to predict the moisture and chemical composition of winter annual forage for routine analysis method to evaluate the feed value.

        This study was conducted to investigate the effect of supplementary feeding levels on livestck and forage productivity and grazing intensity in Elk stags (Cervus canadensis). A fifteen 2-year-old Elk stags about 195 kg were randomly assigned to one of three dietary treatments (five animals per treatment). The dietary treatments consisted of a feeding concentrate of 1.0% of body weight (T1), 1.5% of body weight (T2) and 2.0% of body weight. Total dry matter intake (TDMI) was increased with increased with an increasing supplementary feeding levels. Average daily gain (ADG) were significantly increased with an increasing supplementary feeding levels (p<0.05) and reached a maximum on July and was lower in spring than autumn. The velvet antler production was no differences among treatment groups. Forage productivity of pasture and crude protein content were highest on May and decreased thereafter, however, crude fiber content was the reversed. The grazing intensity of Elk stags was increased in spring (38 to 59 head per ha) than summer and autumn (13 to 32 head per ha). The average grazing intensity of Elk stags ranged from 21 to 34 head per ha, which is affected by supplementary feeding levels. This result suggests that feeding supplementary diet at 1.5 % of body weight was needed to maintain the stable wight gain in antler growing periods and control the proper grazing intensity of Elk deer stags.
