To look at Korea trade environment, as increasing the quantity of goods transported in North-East Asia and deepening national competitive, information-oriented logistics environment is needed. That means it is automated work process and can provide value-added service. To do this, logistics business can be efficiently handled through “Electronic Means for the Clearance of Ships” and electronically data processing. Also, by increasing the risk of international terrorism, regulation regarding to logistics security has strengthened around the advanced country, such as USA and EU, etc. or international organization, such as IMO, ISO, etc.. Furthermore, because trade and logistics environment is changing and security becomes more important in logistics area, movement or status information of goods within the port or in entry in/out becomes more and more be needed in real time. In case cross-border logistics activities, international cooperation or agreement between countries is very important. However, different opinions much happened on defining the interface. If to follow one format or type using at a specific country or organization, it was occurred to difficulty in respect of interoperability as well as additional costs or time. Therefore, this paper proposes common interface model to exchange information for the efficient global SCM for using by the output of Korea R&D project, “National Logistics Standardization System Development”.

WOOL FIBER의 化學反應에 대한 界面活性劑의 影響 : 洗毛工程을 中心으로

朴秀敏 新羅大學校 1981 論文集 Vol.10 No.-

The object of wool scouring is to remove more or less completely the impurities it contains in the raw state such as soluble suint, grease, earth, excrement in order to make it suitable for the subsequent processes of carding, combing and spinning, Inaqueous scouring process tole wool is propelled by fork or arrows through warm alkaline liquors contained soap and detergent, The presence of scouring agent in treatment baths can have a considerable influence on the reations of wool towards Alkali damage and scouring effect. Works on the effect of their presence in wool fiber on the chemical reactivity under various conitions have been published, In order to dissolve this problems, some experiments were carried in the scouring process with scouring machine of 4 bath type. It is considered that a major factor having an effect on quality of scoured wool is the concentration of scouring agent, temperature, treated time and so on. The results of this work are as follows 1. The presence of scouring agent causes an increasing fall in grease content as the concentration of souring agent is raised. 2. Greasy content falls in a long treatment as the temperature rises, on the other hand the damaging effect of the scouring agent increases with methylene blue value as it is increasing absorbed. 3. The structure of wool is rearranged in the hot alkaline treatment of hige concentration of scouring agent and it is damaged on peptide linkages, salt bridges and cystin linkages by alkali action. Owing to this reaction performance of wool fiber is reduced. 4. In order to up yield, it is considered that grease wool can be treated in low temperature of high concentration of scoiurng agent and in a short time.

溶劑處理에 依한 高分子의 吸着擧動 : Polyethylene Terephthalate를 中心으로 on polyethylene terephthalate

朴秀敏 新羅大學校 1982 論文集 Vol.12 No.-

In this paper, the effects of solvents are reported on the shrinkage behavior and the diffusssion properties of polyethylene terephthalate in various solvents. The test results ae that: 1) Supposing T₁as a parameter of the starting temperature of a shrinkage, T₁is related closely with the solubility parameter of the solvents. T₁becomes minimum with solvent whose solubility parameter are similar to these of polyethylene terephthalate. 2) The coefficient of diffusion correlats with T₁, and in creases with decresing T of the polyethylene terephthalate. 3) The temperature dependence of the diffusion coefficient of disperse dyes in solvent dyeing obeys the William-Landel-Ferry equation. 4) The effects of solvents on the diffusion coefficient are explained in terms of the lowering of Ts due to the decrease of the glass transition temperature of the polyethylene terephthalate by absolbing the relevant solvents.

反應性染料의 染色性에 관한 硏究 : Cellulose Fiber를 中心으로 On Cellulose Fiber

朴秀敏 新羅大學校 1981 論文集 Vol.11 No.-

Reactive dyes have been used extensively because of having benefits of bright colour and good fastness by a simple dyeing method. It was widely known that good fastness of reactive dyes was due to strong covalent bonds with hydroxyl group or amino group of fibers. In 1937, triazinyl dyes containing one chlorine atom were described by Fierz and others and the dyes were capable of forming covalent bonds with cellulose. In 1952, Hoechst marketed Remaian dyes containing Vinyl sulfone group to be applicable to wool and silk. In 1954, Cibalan Brilliant dyes, monochlorotriazinyl dyes, were developed. in 1956, the first dichlorotriazinyl reactive dyes for cotton procion MXdyes (ICI) were marketed and they were applicable to cellulosic fiber as surprising dyes. Moreover Cibacron, Procion, and Cibacron Pront dyes for cellulosic fiber were marketed. The characteristic structure of a reactive dye is W-F-B-RG(RG:reactive group, B:bridge, F:chromophore, W:water solubilizing group). and chlorotriazine, vinyl sulfone and chloropyrimidyl as reactive Components are used. Works on chemical reactivity and thermodynamic problem of reactive dyes on cellulose fiber and polyamide fiber have been studied. In order to dissolve problems as the shortening of reactive time and fixing time of reactive with cellulose Fiber, simplicity of dyeing process, saving energy and down of production cost, some experiments about cellulose Fiber dyeing with reactive dyes and assistant under various conditions were carried for the optimum. It is cosidered that major factors having the effect on dye exhaustion ratio are PH, temperature, concentration of assistants of dye bath and treated time. The results of this work are as follows: 1. Dyeing exhaustion increase as PH in dye bath raises. 2. Dyeing exhaustion increases with the increasing concentration of sodium silicate as fixing agent and have very sharp increasing at 6.0% owf. 3. The increasing temperature in dye bath cause dyeing exhaustion upping with the shortening of treated time. 4. Colour fastness to chlorine bleaching and perspiration of cloth treated under the condition tested is excellent. 5. In order to improve dyeing reactivity of reactive dyes on cellulose fiber, it is considered that Cellulose Fiber can be dyed in high PH, temperature and concentration in dye bath according to various structure of dyes.

水溶性高分子와 染料의 相互作用 : Sodium Poly(styrene sulfonate)와 P-Amino Azobenzen과의 相互作用 Interaction between Sodium poly (styren sulfonate) and p-Aminoazobenzene

朴秀敏 新羅大學校 1983 論文集 Vol.14 No.-

The interaction of p-aminoazobenzen with sodium poly(styren sulfonate) was investigated by means of solubility measurement, equilibrium dialysis, spectrophotometric method and dynamic dialysis technique. The solubility of PAAB increases in the presence of PSSNa. The increase in solubility depends on the degree of sulfonation of the polymer. The smaller the D.S., the larger becomes the solubilization. The thermodynamic quantities of transfer of PAAB from water to the aqueous solutions of PSSNa are ??. It was suggested the interaction between PAAB and PSSNa could be interpreted in terms of partition of PAAB between polymer and aqueous phase similar to the dyeing system of nonionic dye and polymer. The spectrophotometric results showed the presence of two different bindings with equilibrium in each case; one was the electrostatatic binding of PSSNa with the dyes protonated at B-nitrogen of the azo group (complex 1) and the other was the binding of these dye molecules with the polymer in term of a mechanism accompanying a change in electronic state of the dyes (complex 2). The binding constants, Kb and K for complex 1 and 2, respectly were calculated by the measurements of absorptivities at 510 and 460 nm for PAAB-PSSNa system. From the results using the dynamic dialysis, the apparent biding donstant, calculated on the basis of free residue of polymer and free and bound dye, was dependent on the dye concentration in all cases examined. The positive cooperativity in the dye binding was suggested by Sigmoidal increases of the binding density, the molar ratio of bound dye to polymer residue, with rise of free dye concentration and by concave upward shape of the Scatchard plot. A speculative model of the interaction was presented in term of the three parameters, n. K. ω.

朴秀敏 新羅大學校 1985 論文集 Vol.20 No.-

Permeabilitles of herium, neon and argon gas into polyacrylonitrile membrane have been discussed in the wide range of temperature from 70 to 140℃ by means of timelag method. The Arrhenius plots of log P and log D vs. 1/T for herium, neon and argon gases gave a sharp changed-point at 96℃ and this point was considered to be the Glass Transition temperature Tg This results have given good incidence to the WLF equation in the region higher than Tg. Diffusion activation enerey of argon was 105 Kcal-mol-1 at 96℃. S lubility of herium, neon and argon gases was interpreted by segment motion and free volume phenomena.
