차광처리에 의한 가시오갈피의 생상촉진현상을 구명하기 위해서, 차광막으로 전천광을 55%, 75%, 90% 차광 처리한 조건과 노지에서 3년간 생장한 개체의 기관별 건물중을 조사하고, 광-광합성곡선과 A-Ci곡선을 통하여 광합성계의 특성을 조사하였다. 그 결과 75%의 차광조건에서는 지하부에 대한 지상부의 비율이 높아지는 현상이 있었으나, 가장 높은 건물중을 나타내 생장촉진에 효율적임이 확인되었다. 그리고 차광처리에 의해서 엽면적당의 엽록소 a+b 함량과 a/b가 감소하고 잎이 얇아지는 반응을 나타냈으며, 개엽 및 개체 당의 엽면적이 증가하는 등의 낮은 광도에 대한 적응반응이 확인되었다. 광합성계에서는 차광처리에 의해서 순양자수율(apparent quantum yield)이 높아지고 광보상점이 낮아졌으며, 탄소고정효율(carboxylation efficiency)과 재인산화속도가 상승하였다. 그러나 순양자수율은 차광처리구의 건물중 상승과는 대응되지 않는 결과를 나타내는 반면에 탄소고정효율은 건물중 상승과 대응된 결과를 나타내, 차광처리구의 광합성능력 증가가 탄소고정계의 활성증가에 기인함이 시사되었다. 광합성에 대한 수분이용효율은 차광처리구가 대조구에 비하여 약간 낮았으나, 모든 차광처리구가 포플러류와 같은 양수에 비해 높은 값을 나타냈다. This study was conducted to investigate and effects of shading treatment on photosynthetic activity of Acanthopanax senticosus. We investigated plant growth, light response curve and A-Ci curve to photosynthesis of A. senticosus at 55%, 75%, and 90% shading treatment. As results, the ratio of above-ground/under-ground biomass was increased at 75% shaded condition and showed highest dry biomass. Under shaded conditions, plants had lower chlorophyll a+b content and a/b ratio and also showed thinner leave. But shaded plants showed higher leaf area and higher total leaf area per a plant. This apparently indicates adapted responses to shaded treatment. Effects of shading treatments on photosynthetic activity were higher in apparent quantum yield, carboxylation efficiency, re-phosphrylation but lower in light compensation point. These results suggested that higher photosynthesis rates in shaded treatments were due to activated carboxylation efficiency. Shading treatment had lower water use efficiency thatn controls but still higher than other tree species.

Ginkgo biloba L. has been planted in the city as street trees because reported as resistant species to air pollutant. Especially, the trees planted on the street of `Cheongro`, Mt `Nam`, and `Jamsil` have been exposed to air pollutant for a long time. This study was conducted to examine chlorophyll contents and genetic variation of Ginkgo biloba in the areas. Chlorophyll contents measured in the above three areas were variable although the the diameter at breast height measured in `Cheongro` and Mt. `Nam` were constant. In addition, the result showed positive relation between chlorophyll contents and DBH in this study. Eight enzyme systems were analyzed in megagametophytes which were collected in the areas and separated to two groups based on chlorophyll contents. All the enzymes appeared to be polymorphic : Got-2, Pgi-2, Pgm, Acon, Mnr, Mdh, Skdh, and 6Pgd. The sensitive (S) groups varied from 1.253 to 2.571 in the genetic diversity and the tolerant (T) groups ranged from 1.416 to 2.825. The observed single locus heterozygosities (H_o) ranged from 0.056 to 0.611 in the S groups, and from 0.179 to 1.643 in the T groups. The expected heterozygosities (H_e) ranged from 0.208 to 0.629 in the S groups and from 0.321 to 0.658 in the T groups. In addition, the H_o values averaged over all loci were 0.326 for the T groups and 0.299 for the S group, respectively. A difference between the two groups was 0.027. The T groups had the unique alleles and genotypes and all the parameters for genetic diversity showed that the T groups had higher genetic diversity than the S groups.

According to court statistics, the number of condominium buildings in Korea was 17,244,047 as of April 2021, and the number of owners of f condominium buildings was 19,809,165. And the number is increasing every year. As a result, various forms of disputes arise between owners of condominium buildings. In particular, section for common use where the distinction is not clear, such as in the subject judgment, can be easily exposed to disputes. In practice, problems arise that are directly related to the economic interests of each sectional owner. This is because the obligation for management (such as payment of administrative expenses) is borne by all of the sectional owners, and sections for common use are borne by the sectional owners who share section for common use. Article 10 of Act on ownership and management of condominium buildings stipulates that “The section for common use is under the co-ownership of all sectional owners: Provided, That the section for common use which is obviously provided only for common use by a certain sectional owners belongs to the co-ownership of those sectional owners.” However, Act on ownership and management of condominium buildings does not mention by what criteria to distinguish between section for common use and section for partial common use. As a result, different judgments are made in each case. The rooftop of apartments subject to the review of the ruling was generally understood as a section for common use, but the first trial ruled that it was a section for common use, the second trial ruled that it was a section for common use, and the third trial judged that it was a section for common use. In this study, I reviewed on the standard of judgment of section for partial common use around court precedents. And then I present interpretations of reasonable criteria under current law and critically consider the conclusions of the decision.

In this study, three tree species (Populus euramericana, Kalopanax pictus and Quercus serrata) exhibiting different levels of shade tolerance were employed to investigate photosynthetic responses to the lower light condition on forest floors. Chlorophyll contents, spectral properties and photosynthetic characteristics were examined by using the tree species grown under high light intensity (PPFD 920μmol m^(-2) s^(-1)) or low light intensity (PPFD 80μmol m^(-2) S^(-1)) . Plants grown under the low light intensity tended to have reduced leaf area, chlorophyll content per unit leaf area, light absorption and respiration in the shade intolerant tree species of P. euramericana. However, the shade tolerant species K. pictus and Q. serrata showed increased leaf area, chlorophyll content and net apparent quantum yield. Therefore, light absorption and light utilization efficiency were improved under the low light intensity. Also shade tolerant species maintained activities of photosystems and CO₂ fixation systems with little changes in low light intensity condition.

동산채권담보법에 의한 채권담보권자의 제3채무자에 대한 대항요건과 제3채무자의 면책기준 - 대법원 2016. 7. 14. 선고 2015다71856, 71863 판결 -

동산채권담보법은 2010. 6. 10. 제정되어 2012. 6. 11.부터 시행된 비교적 신규 입법으로 이와 관련된 대법원 판례가 흔치 않은데, 대상판결은 동산채권담보법에 의한 채권담보권자의 제3채무자에 대한 대항요건과 제3채무자의 면책기준을 다룬 의미 있는 판결이다. 선순위자인 채권담보권자가 동산채권담보법 제35조 제2항의 대항요건을 갖추지 못한 경우에는 제3채무자가 후순위자인 채권양수인에게 변제를 하더라도 해석상 문제는 없어 보인다. 그러나 채권담보권자와 채권양수인이 모두 제3채무자에 대한 대항요건을 갖춘 이후에는 제3채무자가 누구에게 변제를 하여야 면책이 될 것인지가 문제가 될 수 있다. 현행법에는 제3자에 대한 대항요건과 제3채무자에 대한 대항요건이 달리 규정되어 있다. 이로 인해 제3채무자가 누구에게 변제를 하여야 면책이 가능할지에 대해 여러 가지 경우의 수에 따른 해석론이 존재할 수 있다. 그럼에도 현행법에서는 이에 대한 명확한 해석기준을 제시하고 있지 않아 학계의 의견이 분분하였는데, 대상판결은 이에 대한 해석론을 제시고 있다는 점에서 상당히 의미가 있다. 또한 그 구체적인 내용에 있어서도 일정한 요건만 갖춘다면 제3채무자에 대한 대항요건 구비의 선후가 아니라 담보권자와 제3자간의 우열을 따져 선순위 담보권자를 우선적으로 보호되도록 판시한 것은 민법의 기본 법리에 부합하는 타당한 결론이라고 생각된다. 향후에는 이러한 판례의 해석론이 입법의 기초자료로 참고 되어 동산채권담보법의 개정으로까지 진전이 되어야 할 것으로 생각된다. 다만 개인적으로는 장기적인 측면에서는 향후 채권양도, 채권양도담보 등을 동산채권담보법으로 일원화 하여 기존 민법에 의해 인정되던 제도를 폐지하는 방안을 통해 거래계의 혼란을 방지하는 것이 보다 근본적인 해결 방안이 아닐까 생각된다. Act on Security over movable property, claims, etc. is a relatively new legislation enacted on June 10, 2010. The Supreme Court precedent related to this is not uncommon. The object judgment is a meaningful decision against a valid defense against a third-party obligor and immunity from responsibility of a third-party obligor by Act on Security over movable property, claims, etc. If the secured person fails to meet the requirements of Article 35 of Act on Security over movable property, claims, etc., there is no problem with the repayment of assignee. But, after secured person and assignee meet the requirements against a third-party obligor, it may be a matter of question whether the third-party obligor will be entitled to immunity or not. The current law stipulates otherwise about a valid defense against a third party and a valid defense against a third-party obligor. Therefore, there may be an interpretation according to the number of cases in which the reimbursement can be made to whom. Nevertheless, the current law does not offer clear interpretation criteria for this. Thus, opinions of scholars were divided on the subject. However, it is significant that the object judgment is presenting interpretation. The object judgment is significant in its benefits. In addition, it is believed to be a reasonable conclusion to abide by the basic principles of civil law that the court gives priority to secured person. In the future, the interpretation of these precedents should be progressed to the revision of Act on Security over movable property, claims, etc.

取得時效의 要件으로서의 所有의 意思

There are two types of acquisitive prescription system in Korean Civil Law; the one is an acquisitive prescription system by possession, the other is an acquisitive prescription system by register. To obtain ownership by acquisitive prescription by possession, it is required that peaceful and openly possession with intention of holding as the owner for 20 and registration. This study is focused on intention of holding as the owner. We define it as intention of exclusively holding as the owner. And, whether possession with intention of holding as the owner or not is decided not by the inner intention of possessor but by the objective characteristic of title. Article 197 of Korean Civil Law presumes that an occupant possesses by intention of holding as the owner, and the opposite must prove the reason why the presumption can be broken. It is certain that an intention of holding as the owner is only inner intention. But there is question that we decide it by a subjective intention. So whether intention of holding as the owner or not must be decided not by the inner intention but by the objective criterion. Conclusively speaking, it is right that the intention of holding as the owner must be decided by the objective characteristic of title or the circumstances connected with possession.
