In the present communication literatures pertaining to the coat color of Jindo dogs, the natural monument of Korea, have been reviewed. It was reported that there were seven different coat colors in Jindo dogs. They are yellow, white, red, black, tiger-like, grey, and spotted. The yellow and red dogs have typical color markings called "Yibaik", and black dogs have yellow or white color markings called "Nenoonbagi". All Jindo dogs, which have 7 different coat colors with typical color markings, could be found nowadays. The pictures of those Jindo dogs were taken and presented in this communication. It was felt that the coat colors of Jindo dogs should not be limited to yellow and white. And Jindo dogs should be judged not by their coat color but by their noble characteristics.

The Jindo is a Korean native dog, well-known for its hunting and guarding abilities. When he gives his devotion to one individual, he gives it whole-heartedly. He is not tempted easily and impetuous. The breed was not developed. but the dog retained their original qualities -loyal, alert, fearless, obedient, watchful, intelligent, energetic- to survive in the harsh environment of the Jindo island. The dog had been spread over the entire Korean peninsula from the time unknown, and the ones in the Jindo island, isolated until lately, survived and maintained their original characteristics. They are now spread over the entire Jindo County consisted of many islands, whence the breed name came. The Jindo comes in a variety of colors and color combinations, with the fawn and white colorings predominant. The dog is one of the Korean natural monuments, protected by law since early 1960s. The Jindo gained official approval by the Federation Cynologique Internationale as a hunting dog. Apart from the basic housetraining, the dog rarely gets training. Many people have attempted to preserve its pure bloodlines and original qualities. Today, there are a total of 10,356 Jindoes being raised over the entire Jindo County, and many more are kept elsewhere. A research into genetic characteristics of the Jindo is now going on, using the technique of isozyme electrophoresis. The Jindo Dog Breeding Management Center has been reinforced lately, and in addition to their routines, the Center is to work on the breeding of the Jindo. Efforts should be made in the future to produce stable, trustworthy Jindoes according to their proposed use and to modify their temperament in order to make it more widely acceptable as a pet and companion dog in the strangers home.

Jindo Ssitgimgut has been known as a funeral ritual for a long time in Korea. However, there is no study for music therapy on anxiety disorder. The aims of this study were to argue that Oral sound Daseureum of Jindo Ssitgimgut may have meaningful effect on anxiety disorder. Jindo Ssitgimgut is literally a cleansing soul. Jindo Ssitgimgut is designated as the Intangible Cultural Property No. 2 by the Korean government. Jindo Ssitgimgut is transmitted from generation to generation, not the descent of God. So, the accent is on art and one's sincere sympathy. So, with careful listening Youtube, this music Daseureum exhibits an exquisite balance between the human voice and the sounds do the instruments. The author think a good combination of his voice, Jing (Korean gong), and Ajaeng (Korean cello) can help with anxiety disorder.

The Jindo dog is a Korean natural monument and is recognized by the Fédération Cynologique Internationale. A prominent feature is the diverse coat color within the breed. To analyze the genetic basis of variation in the Jindo coat color, we sequenced the protein-coding regions of the melanocortin 1 receptor gene (MC1R). The MC1R coding sequence was determined from 154 dogs in five breeds (Jindo, Labrador Retriever, English Springer Spaniel, Belgian Malinois, and German Shepherd). To confirm the genetic structure of sampled populations, we tested for Hardy-Weinberg equilibrium (HWE) and computed $F_{st}$ The sample populations did not significantly deviate from HWE. $F_{st}$ was 0.02 between white and fawn Jindo dogs; this was lower than $F_{st}$ between breeds. Six single nucleotide polymorphisms (SNPs) were detected in the MC1R coding region. Among the six SNPs, five were non-synonymous (S90G, T105A, Q159P, M264V, and R306ter) and one was synonymous SNP (Y298Y). From the SNPs, we predicted four haplotypes (H1, H2, H3, and H4) for Jindo MC1R. Jindo dogs had different haplotypes corresponding to different coat colors. H1 was frequently observed in white Jindo dogs with an odds ratio of 5.03 (95% CI: 2.27-11.18, p<0.0001), whereas H2 and H4 were observed only in fawn Jindo dogs. Our findings indicate that SNP haplotype can influence coat color. Knowledge of MC1R haplotypes can help discriminate white and fawn coats in Jindo dogs. We hope this report will trigger more research into the genetics of this traditional Korean dog and will be a reference for dogs of Asian origin. Also, our results will provide a useful genetic marker for Jindo dog breeders who have selected for specific colors.

A survey on the seroprevalence of Dirofilaria immitis infection among 2,197 Jindo dogs (371 males, 1,826 females) was conducted from 2011 to 2015 using an antigen test (SNAP 4Dx plus, IDEXX, USA). The overall seroprevalence of D. immitis infection in Jindo dogs was 21.8% (479/2,197), and an increase was observed in the seroprevalence of infection from 19.4% in 2011 to 25.8% in 2015. The infection rates were higher among male dogs (32.1%, 119/371) than female dogs (19.7%, 360/1,826)(P<0.01). The infection rates of D. immitis in Jindo dogs at the age of under 1 years-old, 1 to 2 years-old, 2 to 3 years-old and over 3 years old were 10.7% (76/710), 20.0% (190/950), 36.4% (156/428) and 52.3% (57/109), respectively. The older dogs had higher infection rates than the younger dogs (P<0.01). This study indicates that the prevalence rate of D. immitis in Jindo dogs is higher than previously reported in studies which utilized an antigen test.

This study was performed to investigate the characteristics within ages and freezing tolerance of spermatozoa in Jindo Dog. Experimental animals were selected 12 herds within 1~8 year's old and collected semen for 2 times in a week. Collected semen was evaluated whole volume and sperm number with CASA system (SIAS, Medical Supply, Korea). Then seminal plasma were separated and diluted with modified Tris-egg yolk extender and added 4, 6 and 8% glycerol for 4 times to final concentration and equilibrated for 1.5 hrs. Before and after freezing, equilibrated semen were evaluated the survival rates. Total volume of sperm at 1~2 year old group is as $5.2{\times}10^8\;cells/ml$ largest and there were no significance among groups. The motility of 1~2 year old group is highest as 90.9% and there were significance among groups. Abnormal sperm showed similar among groups. The survival rate in terms of pre-freezing and post-freezing were decreased all levels of glycerol and reveled 87.0% to 64.5% in 4%, 87.5% to 51.9% in 6% and 73.4% to 29.7% in 8%, there were significant difference among the groups (p<0.05). These results suggest that the optimal sperm-freezing methods in Jindo Dog are utilized with modified Tris egg-yolk extender with 4% glycerol and were improve the reproductive activity by these methods.

The origin of Jindo dogs has been controversial. It has been informed by words of mouth that they are the offsprings of either the digs of Sung dynasty (960~1279 A.D.) in China or the Mongolian dogs. Some breeds of dogs in Japan now have almost same appearance as Jindo dogs. The authors reviewed the history of Japan and found that Korean hunting dogs were sent to Japan in early 5th century, which was before Sung dynasty of China. Dr. Jae-Keun Ryu of National Institute of Environmental Research has done some work on serums of dogs of both Korea and Japan; the results of his serological and molecular biological studies indicated that Korean dogs were sent to Japan 1,300~2,500 years ago. Jindo dogs appear to be the descendants of the dogs of the Stone Age. They have adapted themselves to the unfavorable environment of Jindo island so that they can maintain pure line-age and wild nature until today. It was concluded that they are Korean native dogs, not the offsprings of the dogs of Sung dynasty or the Mongolian dogs.

This study was performed to develop ethogram of the Jindo dog's temperament categories under various conditions. A set of 12 behavioral tests were developed to investigate temperament categories expressed by the dogs. Fourty-three adult Jindo dogs(24 males, 19 females) from three different farms located in Jindo island were tested in 12 different behavioral tests. All test procedures and dog's behaviors responded to the tests were recorded using two digital video cameras and one digital still camera. A single observer reviewed all of the videotapes focused on dog's vocalization, movement, head, ears, eyes, mouth, and tail-positions. After all of the behavioral variables expressed throughout the testing period were described in detail, an ethogram of four temperament categories of 'sociability', 'aggression', 'fearfulness', and 'submission' revealed by 12 behavioral tests was developed.

As a part of the commemorative joint faunal survey for the 30th anniversary of the Korean Society of Systematic Zoology, the molluscan fauna of Jindo Island was investigated based on sample collection from 6 localities from the 6 to the 8 of Jul 2016. A total of 114 molluscan species from 47 families were collected and identified. Among these, 42 species from 11 families are newly reported from Jindo Island and combining the previous records with the present study totals 157 species from 57 families. Distribution of species records indicates that marine biogeography of Jindo Island represent an overlapping zone for marine organisms which dwell in the Yellow sea and the southern sea areas of Korean waters.
