This study aims at reviewing the effect of the non-verbal communication of salespersons at service encounter on customers' non-verbal communication and responses. The previous studies overlooked the correlation between salespersons' non-verbal communication and customers' non-verbal communication at service encounter, although non-verbal communication of salespersons has potentialities evoking customers' non-verbal communication and emotional responses in various ways. If it is a salesperson who a customer first encounters within a shop, the non-verbal communication of salesperson affects his/her non-verbal communication and these non-verbal communication affect his/her emotional responses, and these emotional responses affect his/her behavior. This phenomenon is based on the theory of emotional contagion, mimic, and face feedback. Therefore the non-verbal communication such as greetings, postures and eye-contact manners through the personal interactions between salespersons and customers, can be said to be an antecedent variable which affects the positive responses of customer. As a result of the study, the kinesic of salesperson's non-verbal communication was found to affect customers' non-verbal communication, and customers' non-verbal communication affect emotional responses experienced at service encounter, and customers' positive emotion affect customers' behavior responses. This result provides an opportunity which makes one turn eyes on salespersons' non-verbal communication at sales encounter both practically and scientifically, through introducing salespersons' non-verbal communication as an important factor which can enhance customers' positive responses but has been passed over by the previous studies.

Purpose: To investigate request for optical shop startup education of ophthalmic optics students as a basic source for startup education. Methods: Total of 287 students' from three ophthalmic optics college in Kyung-gi region was surveyed and analyzed the data using SPSS analysis. Results: Most students didn't have experience of optical shop startup business education (94.4%). However, the request of startup education was very high (89.9%) and there was significant difference according to grade (p<0.01). The most wanted education for the student who want to opening a shop was a lecture related to finding best place for the shop. For importances of select a site and purchasing information of frame, lens, contact lens in startup education were significant difference according to correction of visual acuity (p<0.001, p<0.05) and optician family present (p<0.05, p<0.001). For importance of customer management and publicity activities was significant difference according to correction of visual acuity (p<0.05). Conclusions: For request of optical shop startup education was very high and need to having startup education.

Purpose: The purpose of this study is to investigate antimicrobial activity of ally derivative of garlic against eye diseases, and to get basic data for an application development of the derivative, as a natural preservative, to multi-purpose solution (MPS). Methods: Antimicrobial activity of allyl derivative of garlic, diallyl sulfide (DAS), against Pseudomonas aeruginosa (P. aeruginosa) and Staphyloccus aereus (S. aereus) was determined. After DAS treatment in MPS of no microbial activity, its growth inhibition effect to bacteria was also determined. Results: DAS concentrations of $IC_{50}$ against P. aeruginosa and S. aereus were found when both bacteria were treated with DAS concentration of 0.25% and 0.64%, respectively. At MPS test, a product from Company A did not show any effects against both bacteria, but one from Company B showed antimicrobial activity against both bacteria. Antimicrobial activity test of the product from Company B in MPS did not showed any significant difference on both gram-negative and gram-positive bacteria. For a trial application of antimicrobial activity of DAS as a natural preservative, DAS was added to MPS of Company A which did not show any antimicrobial activity at treated concentration. Addition of DAS into MPS of Company A resulted in antimicrobial activity of DAS, which suggested a possible application of DAS as a germicide for contact lenses. Conclusions: This study showed allyl derivative of garlic has antimicrobial activity against both P. aeruginosa and against S. aereus, but more effects on P. aeruginosa. The result suggests that allyl derivative derived from garlic can be developed to a preservative of MPS as a natural substance.

We analyzed the demand of competent authorities requiring adequate technical information for initial investigation of chemical accidents. Reflecting technical reports on chemical accident response by environmental agencies in the U.S. and Canada, we presented information on environmental diffusion and toxic effects available for the first chemical accident response. Hydrogen fluoride may have the risk potential to corrode metals and cause serious burns and eye damages. In case of inhalation or intake, it could have severe health effects. The substance itself is inflammable, but once heated, it decomposes producing corrosive and toxic fume. In case of contact with water, it can produce toxic, corrosive, flammable or explosive gases and its solution, a strong acid, may react fiercely with a base. In case of hydrogen fluoride leak, the preventive measures are to decrease steam generation in exposed sites, prevent the transfer of vapor cloud and promptly respond using inflammable substances including calcium carbonate, sodium bicarbonate, ground limestone, dried soil, dry sand, vermiculite, fly ash and powder cement. The method for fire fighting is to suppress fire with manless hose stanchions or monitor nozzles by wearing the whole body protective clothing equipped with over-pressure self-contained breathing apparatus from distance. In case of transport accident accompanied with fire, evacuation distance is 1,600m radius. In cae of fire, fire suppression needs to be performed using dry chemicals, CO₂, water spray, water fog, and alcohol-resistance foam, etc. The major symptoms by exposure route are dyspnoea, bronchitis, chemical pneumonia and pulmonary edema for respiration, skin laceration, dermatitis, burn, frostbite and erythema for eyes, and nausea, diarrhea, stomachache, and tissue destruction for digestive organs. In atmosphere, its persistency is low, and its bioaccumulation in aquatic organism is also low.

Purpose: To investigate the visual function with prescription swimming goggles. Methods: 15 university students (mean age: $22{\pm}1.54$ years) participated, with a mean distance refractive error of RE: S-1.67 D/C-0.40 D, LE: S-1.70D/C-0.37 D. Inclusion criteria were no ocular pathology, able to wear soft contact lenses to correct their refractive error to emmetropia and able to swim. Participants were fitted with contact lenses to correct all ametropia. Subjective evaluation for satisfaction of visual acuity, asthenopia and balance were also measured using a questionnaire while wearing swimming goggles with cylinder (C+1.50 D, Ax $90^{\circ}$) compared with plano sphere outside the swimming pool area. Visual acuity was assessed using the same ETDRS chart. The prescription swimming goggles powers were assessed in random order and ranged in power from S+3.00 D to S-3.00 D in 0.50 D steps. Results: Subjective evaluation was significantly worse for the swimming goggles with cylinder than for the plano powered goggles for all 3 questions, visual acuity, asthenopia and balance. Visual acuity were significantly affected by the different power of the swimming goggles (p<0.05), but there was no significant difference between the in-air in-clinic and underwater in-swimming pool measures (p=0.173). However, visual acuity measured in the clinic was significantly better than underwater for some swimming goggle powers (+3.00, +1.00, +0.50, 0, -1.00 and -2.00 D). Conclusions: Wearing swimming goggles underwater may degrade the visual acuity compared to within air but as the difference is less than 1 line of Snellen acuity, and it is unlikely to result in significant real-life effects. Having an incorrect cylinder correction was found to be detrimental resulting in lower score of satisfaction. Considering slippery floor of swimming pool area, it can be a potential risk factor. Therefore, it is important to correct any refractive error in addition to astigmatism for swimming goggle.

Purpose: This study was assessed to investigate adverse effect induced by overuse of disposable soft contact lenses (CL). Methods: Three disposable lenses (etafilcon A, hilabilcon A, and nelfilcon A) were applied to 19 normal subjects free from any eye diseases for either a single day or variable periods by when subjects complained any discomforts. On the first and last days, localizations of lens' center on corneal surface and blink rates were recorded at every case. Results: Among CL wearers, 10.5% and 47.4% of total subjects quit wearing on the second day and third day, respectively. The case of stopping disposable lens wear was continuously increased with extended hour of lens application. On fourth day, 70.2% of CL wearers reported severe discomforts such as redness, dryness, irritation, pain and blurred vision. When subjects stopped CL wear, decentration of lens from the center of cornea was observed when it compared to the case of single usage of disposable CL. Also about 80% of total subjects showed increased blink rate when CL were worn for more than 2 days. These changes in lens centration and blink rate were consistantly shown regardless of lens types. Conclusions: Blurred vision and acute/chronic discomforts could occur to CL wearers by decentration of lens and increased blink rate when CL were overused more than 2 days even the numbers of two parameters measured in this study were variable by each subject or lens types. Therefore, consideration of individual characteristics and lens types is critical to prevent adverse effects may induced by overusage of disposable lens.

Corona 19 brought about a major shift in the Korean church's pastoral style. Contact and non-contact ministry styles using the Internet and media devices are being held together. The elderly, who have been classified as digital vulnerable, need to see whether they are properly adapting to these changes and they have any difficulties in their religious lives. This study is to organize the current status of Corona 19 related to Korean churches, look at the current state of church programs for Christian elderly people, look at how important the religious life is to their lives, and to suggest educational pastoral methods for their religious lives based on the theory of Maria Harris' educational ministry. First, in terms of Koinonia, it was suggested that the heritage, beliefs, values and ways of life held by the Christian elderly be shared with people inside and outside the church in order to entertain and embrace everyone without alienation. Second, from the perspective of Leiturgia, educational ministry was proposed to expand prayer life from a personal area to a public area to become a life of practicing prayer and justice by providing public prayer content with media that can be used by the elderly to perform spirituality. Third, it was suggested that in terms of Didache, it should be required that the elderly should be educated to be familiar with the changing technologies, that teaching environment should be extended from church to online, and that the educational content of tradition and new forms should be dealt with extensively. Fourth, from the perspective of Kerigma, Christian elderly people who have suffered in various life environments, both personally and socially, should listen to the words again and gain the power to overcome the corona crisis through the God's words, so that they can be melted into the curriculum of koinonia, leiturgia, didache, and diakonia. Fifth, it was suggested that senior citizens should switch their consciousness to become subjects of service, not objects of service, and that digital literacy education should be provided individually at eye level to narrow the digital gap for Diakonia curriculum.

The purpose of this study is to provide improvements and standards of trial lens, in a situation that there is a lack of standards of trial lens set that have been used for self-conscious refraction test after helm refraction test at about 5,000 opticians, ophthalmologic clinics and hospitals, and contact-lens shops, that there is a lot of discrepancies between refraction specified and the actual power, and that there is no regulation of optical tolerance error. For the study, opticians who have used Trial lens set were asked to participate in a questionnaire survey through continuing education, and divided into those who have used domestic lens and those who have used imported lens, 5 opticians each for less than 5 years, 5 to 10 years, more than 10 years. The measurement of both refraction specified and the actual diopter was compared to Japan Industrial Standards(JIS T4402). As a result of comparative analysis, more than 80% of respondents have had reliability on the refraction of trial lens they had used, indicating that they have never measured the refraction specified and the actual diopter after buying them. Besides, Korean Industrial Standards(KS P4402) has been imperfect in diopter range since it was legislated in 1979. More than 95% of respondents have been unsatisfied with optometry. Also, it has indicated that refraction error is more frequent in long-term-used trial lens. The conclusion is that it is necessary to standardize trial lens set and that it is required to add lens to lens set provided under KS P4402. Moreover, it is necessary to have supervisory agency for a standardization of trial lens. I hope that both domestic lens and imported lens, as in German and Japan, will be tested to find whether they meet optical tolerance error and standard trial lens will be distributed. Good optic inspection is required for the improvement and management of eye health and optical function, and the same standard trial lens set should be used. whoever is tested. Also, I hope that trial lens set will be specified within standards and tolerance error.

Culture is already deeply imbued in our lives. The furniture has become a way of life and the human became part of the culture. In this study, the aim is to explore the traditional furniture that is projected through the culture as a lifestyle. Therefore, the purpose of this study is to explore the cultural implication in Korean traditional wooden furniture. Specific research questions in this study are as follows; 1) How to reflected house structure culture at traditional woodcraft furniture? 2) How to reflected interior space culture at traditional woodcraft furniture? 3) How to projected life form style culture at traditional woodcraft furniture? 4) How to harmonize between modern life culture and traditional woodcraft furniture? In order to achieve the purpose of this study, the literature of review was used masters of Korea's traditional woodcraft furniture. To collect information of Korean traditional furniture, the furniture was selected representative pieces of Korean Joseon Dynasty and interviewed an important intangible cultural asset somokjang. Based on the explore of Korean traditional furniture, the conclusions of this study are as follows; first, in the viewpoint of house framework culture, most of traditional furniture was made u sing a narrow interior space and was to be placed in close contact with the walls, and was developed as a type of molding on the front of the furniture to pursue beauty. Second, in the viewpoint of ondol culture, traditional furniture was closed to the wall by using low height furniture and furniture legs the structure punghyeol was used to reflect the phenomena of convective heat and humidity. Third, in the viewpoint of life form culture, traditional furniture was made that sat-down at eye level configuration is proportional to its size and height and appropriately been made. And patterns reflect the wishes of most things in nature and to be blessed with longevity origin were used in the decoration of wooden furniture. Finally, in the viewpoint of modern life culture, traditional furniture is simple but not dirty, and splendid but not luxurious. So although traditional wooden furniture are in any room or place, never discouraged by the dignity.

The purpose of this study is to research the correlation of Sijo with Akjang. In Joseon Dynasty, the contact of folk music and court music was brisk. Although they had some political premises, many Jeongjaes presented in the royal court parties accepted Gagok, one of the representative folk song genres. It was an eye-opening matter. The song words sung by Gagok music accompaniment were the lyrics of Sijo. We can give Sijo that was used in diverse royal court parties as an typical example about introduction of folk music to the court music. A lot of Goryeo Dynasty's Jeongjaes were introduced to Joseon Dynasty nearly as they are. Naturally so most Sokak-gasas were. Bukjeon was sung to Jinjak tune which Jeong-gwajeong was sung. Bukjeon in the music book Akhak-Guebum is a long song, but instead Bukjeons in the music book Geumhapjabo and Yang'geum-sinbo are short. It suggests that the poetic form of Sijo was introduced to the Lyric of royal court music from a point of time in the early Joseon Dynasty. Especially, Bukjeon had been continued to the late Joseon Dynasty after exchanging to the lyric form of Sijo. Bukjeon had been used In the royal court to the first half of Joseon Dynasty It became established in the repertory of Gagok after spreading to people out of court. Turnover from the long Bukjeon to the short was a result that the folk music influenced royal court music. Bukjeon. song words praying King's longevity. was used in the diverse situations such as a small royal parties, royal archery, and King's outing. It can be a clue that the Korean song words continued to late Joseon Dynasty were used for the lyric of royal court music. In the correlation of the poetic form of Sijo and Akjang, we can find out some characteristics different from our common sense to distinguish royal court music from folk music.
