At EUROCRYPT 2015, Todo proposed a new technique named division property, and it is a powerful technique to find integral distinguishers. The original division property is also named word-based division property. Later, Todo and Morii once again proposed a new technique named the bit-based division property at FSE 2016 and find more rounds integral distinguisher for SIMON-32. There are two basic approaches currently being adopted in researches under the bit-based division property. One is conventional bit-based division property (CBDP), the other is bit-based division property using three-subset (BDPT). Particularly, BDPT is more powerful than CBDP. In this paper, we use Boolean Satisfiability Problem (SAT)-aided cryptanalysis to search integral distinguishers. We conduct experiments on SIMON-32/-48/-64/-96, SIMON (102)-32/-48/-64, SIMECK-32/-48/-64, LBlock, GIFT and Khudra to prove the efficiency of our method. For SIMON (102)-32/-48/-64, we can determine some bits are odd, while these bits can only be determined as constant in the previous result. For GIFT, more balanced (zero-sum) bits can be found. For LBlock, we can find some other new integral distinguishers. For Khudra, we obtain two 9-round integral distinguishers. For other ciphers, we can find the same integral distinguishers as before.

The judgement which is subject of research has denied legal rescission of division of the inherited property by agreement based on (1) the fact that the division of inherited property terminated at the time of concluding mutual agreement in its nature while only the relationship of claim and obligation between the inheritor who has paid for such obligation and the inheritor who has acquired such obligation in the mutual agreement remains (2) and the fact that the legal stability is considerably hindered as the re-partition of inherited property having retroactive effect becomes unavoidable in case of approving the legal rescission of the division of the inherited property by agreement. But it is reasonable to also approve legal rescission on the division of the inherited property by agreement in case the division by agreement actually has the nature such as conditional donation between joint heirs (1) from the fact that the division of the inherited property by agreement gets the nature of disposal equivalent to exchange, transfer and abandonment of share between joint heirs in actuality, (2) and the fact that there are no other theories in approving the validity of mutually agreed rescission despite the fact that the re-partition of inherited property having retroactive effect is unavoidable even in case of the mutually agreed rescission of the division by agreement among all joint heirs. However, as the division of the inherited property by agreement is a contract that gets concluded only if all joint heirs participate, even the legal rescission for the reason of not fulfilling the obligations paid by one party of the heirs during the division by agreement must be considered as possible only by expression of intentions from all other joint heirs excluding this one party.

This study, with a view to establishing the objective and concrete methodology of partition of properly by the married couple in the process of divorce, is to suggest the calculation method of impartial division of property by means of applying the system to division of remainder used in Germany. Generally, the process of estimating the amount of partitioned property has two steps, the first of which is to calculate the remainder of the husband and the wife each. The second step is to compare the remainders of the couple and calculate the difference in order for the spouse who has more to claim the payment of a half of the difference. This method has the advantage of dividing impartially the remainder obtained by labor in the married life.

The reformed family law was enforced from Jan.1,1991 and the claim to division of matrimonial property in case of divorce, a newly enacted right in the law, is expected to increase the economic position of married women. By this system, married woman can claim her share in the matrimonial property in case of divorce if she verifies her contribution to it. But actually, household work of housewives has not been evaluated properly as compared with their husbands' work in deciding of property division rate, because there is no economic base about the value of household work. So, this study verified wives' role of contribution to matrimonial property and compared their work hours with their husbands. As the result, following suggestions can be presented. 1. The contribution rates of husband and wife to the matrimonial property have to be acknowledged equally and, in case of employed wife, her rate has to be evaluated higher than her husband. 2. Because the property division is not a solatium but a transfer of wife's share, responsibility which marriage has dissolved should not be taken more to women than men. 3. Decision of division rate has to be made regardless the amount fo property unless there are special reasons. 4. The donation tax and inheritance tax should not be imposed on matrimonoal property which was returned to wife from her husband.

Silkworm powder's thermal property is an important factor for its storage and marketing. This study examined the effect of edible enzyme on the thermal property of silkworm powder using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). Results of the TGA showed that regardless of the enzyme treatment, the weight loss patterns of silkworm powders exhibited 3 step thermal property deterioration at approximately $80^{\circ}C$, $280^{\circ}C$, and $480^{\circ}C$ due to water evaporation and thermal degradation. This is similar with the DSC which also resulted in all samples two endothermic peaks attributed also to water evaporation and thermal degradation. These results indicated that the use of enzyme such as protease and cellulase might not affect significantly the thermal properties of silkworm powder.

Film morphology, crystallinity, and luminescence property of solution processed ZnO films have been studied. Fluorine addition and annealing ambient significantly change the defect-related emission band as well as the structural property. Using the overall emission behaviors, we can predict an optimized process condition for solution-based ZnO thin film.

In tissue engineering application, a fibrous structure of scaffolds has been issued as an alternative system to regulate cell survival and tissue regeneration, and electrospinning technique has been popularly used to generate fibrous meshes or sheets mimicking the structure of native extracellular matrix (ECM). However, recent strategy in the scaffold development is expanded to provide the structural property as well as a biological property of native ECM, a variety of surface modification techniques have been used to introduce biological property. In this study, we developed biomimetic poly(L-lactide-co-${\varepsilon}$-caprolactone) (PLCL) nano- and micro-fibrous scaffolds as a unique platform with structural and biological properties with native ECM using electrospinning method and gamma-ray irradiation. Surface morphology of the scaffolds was observed by scanning electron microscopy, and alteration of surface property was evaluated with toluidine blue O staining, water contact angle measurement and ATR-FTIR analysis.

When 4-hexylresorcinol (4HR) incorporated silk mat is used for clinical application, sterilization process is essential. In this study, 4HR incorporated silk mat was sterilized with ethylene oxide (EO) gas or autoclave, and then antibacterial property was evaluated. For the examination of micro-structure after the sterilization, scanning electron microscopic (SEM) exam and Fourier Transform Infrared (FT-IR) spectroscopy were also done. There was no gross difference after sterilization in SEM exam and FT-IR spectra. Antibacterial property of 4HR was also maintained after the sterilization. In conclusion, EO gas or autoclave did not damage the antibacterial property of 4HR in the silk mat.

We investigated on the additive effect of carbon nanotube in the sulfur electrode on the first discharge curve and cycling property of lithium/sulfur cell. The sulfur electrode with carbon nanotube had two discharge plateau potentials and the first discharge capacity about 1200 mAh/g sulfur. The addition carbon nanotube into the sulfur electrode did not affect the first discharge behavior, but improved the cycling property of lithium/sulfur cell. The optimum content of carbon nanotube was 6 wt% of sulfur electrode

This study was carried out to investigate the cause of leaf discoloration occurring frequently in paddy cultivation. Chemical property of soil and inorganic nutrient component of leaf were analyzed on abnormal fields of 7 regions where leaf discoloration occurred severely and normal fields of 7 regions among ginseng garden. The pH of abnormal fields was strong acidic condition (pH 5.51) compare to normal fields of slightly acid condition (pH 6.42). Calcium and magnesium content in abnormal fields were lower distinctly than that of normal fields, while EC, organic matter, phosphate, and potassium content showed not distinct difference between abnormal and normal fields. Whereas calcium and magnesium content were distinctly high in normal fields, both of potassium and iron content of ginseng leaf were distinctly high in abnormal fields. In particular, iron content of abnormal fields was more 1.94 times in soil, and 3.03 times in leaf than that of normal fields. In soil chemical property, there were significant negative correlation between leaf discoloration ratio and soil pH, and there were also significant positive correlation between leaf discoloration ratio and iron content. In ginseng leaf, there were highly significant negative correlation between leaf discoloration ratio and calcium content, and there were also highly significant positive correlation between leaf discoloration ratio and iron content.
