Carchesium polypinum and Vorticella campanula were collected in freshwater ponds and reservoirs on Jindo Island and other places in Korea. These two vorticellids are newly recorded in Korea. The two species are described using live and silver impregnated cell observations, morphometry, line drawings, and microphotographs. Characterizations were based on the following diagnostic features: Carchesium polypinum was observed mainly as a funnel to fanshaped colony, basically dichotomous branching pattern, discontinuous spasmoneme, subconical shaped zooid, J shaped macronucleus, ventrally positioned single contractile vacuole, and pellicular striation with 61-80 rows between the peristomial lip and aboral ciliary wreath, and 18-30 rows between the aboral ciliary wreath and scopula. Vorticella campanula was conspicuously characterized by the broadly bulged peristomial lip, wide conical shaped zooid, J or S shaped macronucleus, ventrally positioned single contractile vacuole and pellicular striation with 64-75 rows between the peristomial lip and aboral ciliary wreath, and 27-41 rows between the aboral ciliary wreath and scopula. We provide redescriptions of two well-known vorticellids with detailed drawings and descriptions of oral ciliatures from Jindo Island and other places on the Korean peninsula.

Hermaphroditism occurs rarely in human and animal populations. Previously, in Korea, The hermaphrodite dog in American Cocker Spaniel dogs have been reported in six cases. However, in this case, we found a hermaphrodite dog in Korean native Jindo dog. The characteristics were its enlarged os clitoris that was shown a reddish fingerlike structure protruding from the vulva. The dog was diagnosed as hermaphroditism with ovotestes. To our knowledge, this report is the first case of hermaphroditism in Korean native dog.

Freshwater benthic macroinvertebrates were investigated from five sampling sites on Jindo Island located in the southwestern end of the Korean Peninsula. A total of 47 species (average $14{\pm}3.16$ species per site, 40 species in lotic area, and 13 species in lentic area) belonging to 38 families, 14 orders, 5 classes, and 3 phyla were sampled. Coleoptera, Diptera, Ephemeroptera, and Trichoptera were the major groups of benthic macroinvertebrates with relatively high species richness. Species diversity indices (H') and richness indices (RI) of upper streams were relatively higher than those of lower streams, which were affected by agricultural effluent from the paddy fields.

VTS service results from VTS watchman's mind as all other human conducts. Psychological motivations are divided into 4 factors ; collective unconscious, fear, responsibility, humanity. These motivations are beginning of VTS. Motivations awaken watchman and effect all other steps of service. Out of these motivations, higher factors ; responsibility and humanity act very positively and can be best solution for safety of vessel traffic ; the purpose of coastal VTS. Therefore, VTS officers should be educated to build up these virtues in their mind.

The trunk and limb of the Jindo, Korean native dog was measured in the present study. One hundred and ninety five Jindoes were randomly selected from the 1,985 dogs in the Jindo County in August 1998, which were screened by the judging committee of the County and registered by inserting electronic chips in the withers. They were about a year and half old, and were white and fawn dogs. A total of 18 parts of the trunk and limb were measured using calipers and tapes. The average height at the withers was 50.67 cm in dogs and 47.48 cm in bitches. The average body length was 52.99 cm in dogs and 50.33 cm in bitches. And the average height : body length ratio was 104.70 in dogs and 106.08 in bitches. No differences were observed between the Jindoes of the two coat colors in these measurements. The results of this study would be useful for compiling the official standard for the adult Jindo.

Hemoglobin, albumin and transferrin phenetypes observed in a population of 255 dogs of various breeds by agar gel electrophoresis for hemoglobin and albumin, and by starch gel electrophoresis, for transferrin. The results obtained were as follows: 1. The hemoglobin phenotypes were classified as HbAA, HbAB and HbBB and the frequencies of appearence were 91.77, 6.27 and 1.96%, respectively. Gene frequency studies of $Hb^A$ and $Hb^B$ showed the $Hb^A$ gene to have a frequency of 94.9% and $Hb^B$ gene to have a frequency of 5.1. The frequency of hemoglobin phenotypes of the Korean Jindo dog (ylelow) was HbAA 76.19%, HbAB 17.46% and HbBB 6.35% and HbBB was recognized only in the Korean Jindo dogs. 2. The albumin phenotypes were calssified as AlbAA, AlbAB and AlbBB and the frequencies of appearence were 28.71, 43.57 and 27.72% respectively. Gene frequency stduies of $Alb^A$ and $Alb^B$ showed the $Alb^A$ gene to hate a frequency of 50.50% and $Alb^B$ gene to have a frequency of 49.50. The frequency of albumin phenotypes of the Korean Jindo dog was 26.32% for AlbAA, 34.21% for AlbAB and 39.47% for AlbBB. The frequency of albumin phenotypes of the Korean Jindo dog was slightly different from others and gene frequency of $Alb^B$ was 56.58. 3. Transferrin studies resulted in findings of 10 different phenotypes and frequencies of transferrin phenotype were 30.08% for $TfA_1A_1$, 8.02 for $TfA_2A_2$, 2.11 for TfBB, 4.64 for $TfC_1C_1$, 1.69 for $TfA_1B$, 41.35 for $TfA_1C_1$, 5.49 for $TfA_2C_1$, 0.84 for $TfA_2C_2$ and 3.79 for $TfBC_1$. Gene frequency studies of $Tf^A$, $Tf^B$ and $Tf^C$ showed the gene to have a frequency of 63.08% for $Tf^A$, 4.85 for $Tf^B$ and 32.07 for $Tf^C$ 4. Transferrin studies revealed two different band patterns on starch gels with a strong and weaker stained one. The $TfC_2C_2$ and $TfA_2A_2$ which were found in the Korean Jindo dog only showed a weaker stained band and the gene frequency of $TfA_1A_1$ was highly recognized in this dog.

This investigation was conducted on 249 Jindo dogs aging from 2 to 12 months to determine body type and external appearance of the dogs. The results of this investigation were as follows. 1. The withers height of male dogs growed rapidly during the period between 2 months and 7 months of age, and was 22.94cm and 49.77cm, respectively. Afterward the growth rate slowed down up to 12 months, 53.33cm. The growth rate of female was similar to male, and the withers height was 22.91cm, 46.81cm, 48.70cm at 2, 6 and 12 months of age. 2. For male and female the body length was 27.21, 27.23cm at 2 months, 51.40cm, 51.62cm at 6 months, 58.33, 52.15cm at 12 months, respectively. Growth rate of the body length was very rapid from 2 to 6 months of age, but afterwards the growth rate was slow and somewhat retarded. 3. For male and female, the withers height to body length ratio was 100 : 109.4 and 100 : 107.1 in 12 months old group. 4. Cross over between the sexes in growth rate occurred between 5.3 to 6.5 months of age for wither height, between 6.0 to 7.2 months for hody length, respectively. 5. The average chest girths of male and female were 31.46, 30.46cm at 2 months, 54.92, 52.20cm at 7months, 60.25, 57.90cm at 12months, respectively. The growth rate of chest girth was rapid between 2 to 7 months of age and gradual between 7 to 12 months. 6. The average skull lengths of male and female were 11.76, 11.32cm at 2 months, 21.83, 19.60cm at 12 months, respectively. The average head widths of male and female were 8.37, 7.94cm at 2 months, 15.47, 12.46cm at 12 months. 7. Erected type of ear was completed from oblique type at 6 months in male and 7 months in female. On our detailed examinations, we concluded that Jindo dogs completed their growth at 6 to 7 months of age.

This study is planned to discover the behavior of Korean peasants cope with the changes of structure last 30 years. So, I have surveyed the activists of Jindo Peasants Association through questionnaire. The outcome of survey are as follows; First, Peasants movement have been become weakened and the hope of future have disappeared. Although they have resisted the pressure of structural changes zealously, their life conditions have worsened. So, Peasants movement have been become weakened and they have no alternative choice. Second, The economic situations of all activist those who surveyed have worsened and there is no exits. If looking only at the surface of things, the socio-economic situations of Jindo peasants activists show a tendency to polarization. But, to tell the truth, overall immiseration have occurred at Jindo area. Third, confusion of their sense of values and weakening of self-esteem have occurred among the Jindo peasants activists. It is because that farming which is evaluated high in respect to cultural and industrial perspective, have been eliminated and disregarded. Especially, worsening of earnings and expenses make the peasants to be in the worse situations.
